Which solar system is good for the home?

When it comes to solar systems for homes, there is no one-size-fits-all answer. The best solar system for your home will depend on several factors such as the amount of energy you need, the size of your roof, your budget, and your location. There are 4 types of solar systems available in the market: On-Grid Solar System: An on-grid solar system, also known as a grid-tied solar system, is a solar power system that is connected to the electricity grid. This type of system uses solar panels to generate electricity from the sun and then feeds that electricity into the grid for use by homes and businesses.

One of the benefits of an on-grid solar system is that it allows homeowners to use solar power when it’s available and to draw electricity from the grid when solar power isn’t sufficient. This can help to reduce energy costs and can also provide a backup power source in the event of a power outage. Since an on-grid solar system does not require batteries, it is cheaper to install when compared to an off-grid system. It is less costly when compared to other solar systems. It involves less maintenance and generally has a longer life when compared to an off-grid system. This system can be used with string, micro, or hybrid inverters. Off-Grid Solar System: If you live in a remote area or experience frequent power outages, you may want to consider an off-grid solar system. An off-grid solar system includes batteries to store excess power for use during times when the sun is not shining. However, this type of system can be more expensive and require more maintenance than a grid-tied system.

Unlike grid-tied solar systems, which are connected to the utility grid, off-grid solar systems are designed to store excess energy in batteries for use when the sun is not shining. This allows users to have access to electricity even in remote areas where the utility grid is not available. Hybrid Solar System: A hybrid solar energy system is a combination of on-grid and off-grid solar systems. It is basically a grid-connected system with a battery backup. So, it has the advantage of both storing excess energy in the battery as well as selling the surplus energy generated to the grid.

The advantage of a hybrid solar system is that it can provide a reliable and consistent supply of electricity, even when weather conditions are not ideal for solar energy production. For example, a hybrid solar system with battery storage can store excess energy generated during the day and use it to power the home or business during the night or on cloudy days. Direct Solar System: If a person wants to run his appliance like a water pump, atta chakki, etc. through a solar panel, he can use a Direct Solar system. Solar panels and VFD are the two main components of this kind of system. To determine the best solar system for your home, it’s important to consult with a professional solar installer who can evaluate your specific needs and recommend the most appropriate system for you.

Solar Pump Market Latest Trends and Future Growth Study 2022-2030

The solar pump is a system that runs on electricity produced by photovoltaic panels for pumping water. It is an ideal alternative option for replacing conventional generators that function by utilizing energy from fossil fuels for pumping water. Solar pumps generate electricity from sunlight.

Solar water pump converts solar energy into electricity for running the pumping system, hence replacing the erratic grid supply and diesel-powered system. It is powered by solar modules that support drawing groundwater for irrigation.

Usually, remote places rely on diesel engines and manpower for water supply. As solar pumps replace conventional pumps by offering numerous benefits such as weather-relevant, and socioeconomic, therefore, these pumps are massively utilized for irrigation and water shock application.

Solar pumps are easy to install, robust, and require minimal maintenance. The lifespan of solar pumps is around 20 years. Solar pumps are widely used in areas with electricity problems.

Working Mechanism of Solar Pumps: PV panels experience sun rays by solar energy, these rays are further converted into electrical energy with the support of Si wafers located within the PV panels. The electrical motor pumps system operations through cables by utilizing the solar energy. The pump picks up the soil water and supplies it to the fields by shaft revolution.

Submersible Solar Pumps Submersible solar pumps have the potential to lift water up to 650 ft and can be easily installed in a big well. When water depth reaches 20 ft above the earth's surface, then the batteries and solar panels are turned off. In several cases, it sources to power. Usually, water is pumped throughout the day, as the sun shines, and water is stored in the tank for usage. It is suggested to store water in good weather conditions, as it will not pump water in bad weather.

Surface Solar Pumps Surface solar pumps are utilized in shallow wells, storage tanks, and ponds. If water depth reaches 20 ft or less from the surface, pumps cannot pick the water high from the well. These pumps can push the water to a distance of 200 feet or more. These pumps are ideal for pumping or lifting water from a high depth of 20 meters.

Floating Solar Pumps Floating solar pumps provide convenient solar pumping from surface water resources or water troughs. There are varying applications for these pumps such as livestock watering, micro-irrigation, drainage, and aeration.

Rising agricultural application of solar pumps leads to their increasing demand, which, in turn, drives the solar pump industry revenue. It is due to the rising adoption of renewable energy sources, and to decline in the consumption of fossil fuels for irrigation in agriculturally based economies, such as China, India, and a few in Africa. Therefore, the increasing agricultural application of solar pumps for irrigation results in their growing demand.

Will chancy returns in rural microgrids ever get better?

Data monitoring and analytics of the solar PV assets is the key to success of energy access programs across the World.

Microgrids -- distributed systems of localized generation, distribution network, and load -- are being increasingly deployed particularly in rural areas of emerging and under-developed countries to achieve energy access.

 India has been a pioneer in rural microgrids since the 1990s, however, there is significant progress to be made despite rapid advancements in technologies like solar PV, energy storage and affordable LED lighting solutions. 

India Energy Storage Alliance. (IESA) estimates that India has installed over 2,000 AC microgrids of over 5 kW by 2016 and over 10,000 DC microgrids with the majority sized at less than 1 kW.

Initial funding in the sector was made by the national and state governments in form of subsidies and also in form of grants by international organizations such Asian Development Bank (ADB), the World Bank, USAID, and others. 

This funding encouraged many entrepreneurs to implement their unique ideas for electrification through various off-grid technologies. Following the grants, several institutions and foundations such as Rockefeller Foundation introduced soft loans in this sector at affordable lending rates. 

It is not reported though, but not every asset is providing expected returns and these assets are not breaking even in a period of 10 years.

The enthusiasm of entrepreneurs and local government agencies working as project developers has yet not conquered the challenges in the fields and hence funding in form of grants and soft loans have rarely scaled in the form of private investments.

 Evermore funding in the form of soft loans, private capital and equity is required to plug the funding gap. Over US$49 billion a year until 2030 would be needed to achieve energy access across the world. Out of this, ADB has quoted that only US$9 billion of funds are available globally.

Well, the business risks here can be easily classified as financial collection risks and asset performance risks. However, the challenges around the performance of assets will be more difficult to address at this point in time.

Growth restraints include poor visibility of performance

There are many challenges that have restrained growth in this sector including numerous financial, technical and social limitations. Different funding agencies have mentioned that most of the technical challenges are not yet known to them. 

Project operators on several occasions do not have clear answers themselves to recognize why microgrids are prematurely failing or operating at lower efficiency. Interestingly, funding agencies, investors and equipment suppliers are often surprised by news of the sudden failure of assets or technical audits reporting the poor functionality of microgrids. As could be predicted, these microgrids are manually monitored or not monitored at all. And hence, the inaccessibility of data, in this case, has led to a lack of analysis and knowledge generation.

In many of the cases, project owners and operators are not be blamed as poor telecom connectivity and the high cost of remote monitoring at remote locations has plagued data acquisition and analysis. 

The international Microgrid Initiative for Campus and Rural Opportunities (MICRO) is working with different remote monitoring hardware suppliers to bring down the costs by simply bringing economies of scale and developing cheaper products for rural microgrids and for areas with limited telecom signal accessibility.

In this regard, IESA has collaborated with the European Space Agency (ESA) to bring satellite communication technology as an alternative solution. ESA is now launching a new invitation to support feasibility studies that identify and explore business opportunities for deploying services based on satellite communications, earth observation data, and/or other space assets to support the decentralized management of microgrids in India and other developing countries.

 The study is expected to culminate in a funded microgrid pilot project demonstrating the potential of the above services.

An IoT for a fragmented and unorganized sector

The other challenge is that the sector is fragmented and unorganized, which is leading to its inefficacy. This, in turn, is causing roadblocks for social and technological innovation at the very bottom of the social pyramid, leading to microgrids and related off-grid solutions becoming an expensive affair.

In this context, a need for a platform to bring transparency and innovation to the system has been recognized. Customized Energy Solutions, a leading energy services company, has developed an initiative under the India Energy Storage Alliance that looks to provide the rural consumer with affordable and reliable power. 

The Microgrid Initiative for Campus and Rural Opportunities (MICRO) has set a goal of reducing the cost of electricity in rural microgrids by 30.0% within the next 3 years through innovation and collaboration across stakeholders.

At the heart of MICRO lies an IoT (Internet of Things) based portal which incorporates a remote monitoring platform with supply, demand, and funding aggregation capabilities. 

The portal is a unique multi-stakeholder platform that allows the industry to work as a bazaar where different stakeholders like project developers (or ESCOs), funding agencies and equipment suppliers can communicate with each other, realize future business opportunities and validate the performance of current assets. 

MICRO is looking to involve a variety of stakeholders, namely technology providers, regulators, microgrid developers, end-users through local not-for-profit organizations and funding agencies in its effort to make microgrids techno-commercially sustainable and link electricity to economic development.

The microgrid is much more than a solar generation plant

The operation of a microgrid has evolved as a multifaceted task that involves the dedicated upkeep of various components. The activities here revolve around the maintenance of the generation plant, network planning, and expansion, customer acquisition, billing, and recovery. 

The early-stage expansion has red-flagged many issues in these grids such as voltage drop, the inability of serving high inductive loads and reliable power output. The stakeholders in this industry would need to think beyond the microgrid as just a solar generation plant and provide a complete set of diagnostic and analytical tools to microgrid developers and operators in order to achieve the target of energy access in India through over a hundred thousand microgrids in India.

Future Energy Systems Powered by Power Electronics

What is common to using our smartphones and driving an electric car to work? We can charge both efficiently and effectively because of Power Electronics. Power Electronics is the application of semiconductor electronics to convert electric power and to control it. Power electronics is at the core of converting energy from one form to another and is responsible for 70% of the power conversion that is happening around us already and is predicted to increase. It is one of the key enablers for carbon-neutral energy systems which are the energy systems of the future.  In this article we will explore the various ways in which technologies centred around Power Electronics-centric will power the energy systems of the future.

Role of Power Electronics Today

Power Electronics is an enabler for solutions from generating power to power consumption such as battery energy storage systems, pumped hydro storage, hydrogen production. It is also responsible for the conversion of energy to electricity. As we know Power Electronics touches our everyday life through our personal smart devices, induction stoves, electric vehicles, and other such appliances. Power Electronics plays a key role in the automotive sector making it possible to charge and recharge electrical vehicles quickly and reliably leading to an e-mobility revolution globally. With Power Electronics, AC and DC power solutions can co-exist. PE enables us to integrate diverse energy sources such as solar PV, wind turbines, batteries, power backup generators in the form of micro-grids. PE is enabling electrification even in remote urban areas and helping us move towards greener energy alternatives at an affordable price.

Future of energy systems

Power Electronics is the key to sustainability and using green energy. Some of the applications of Power Electronics in the future are envisaged to include the following:

1.     High Voltage Direct Current  (HVDC)

Stronger and more flexible networks are necessary to distribute power that is generated from renewable energy sources to the point where it is used in various sectors such as transport, industrial and others. Equally necessary are flexible storage options such as batteries for short-term storage to long-term storage solutions such as hydro energy storage plants.

HVDC technology is a powerful tool that has enabled the unprecedented task of connecting asynchronous power grids.  This has even allowed for bulk power transfer between countries across the sea.  The power grids connecting France and the UK are a primary example. Embedding HVDC links into existing networks is envisaged to make regional grids more flexible and resilient in the future.

2.     E-mobility

 Electrification of railways is considered to be a major step in controlling environmental pollution. One of the major challenges posed by the electrification of the railway system is the provision of different AC voltages and frequencies as well as providing DC voltage for their operations. Power Electronics plays a crucial role here by allowing the power to be drawn off the main grid to make electrification sustainable.  

 We are beginning to see Electric Buses in some cities. These have a power storage battery that is charged by power off the main grid. Charging can take several hours and the storage batteries are also large in size. Power Electronics enables ‘flash charging’ at bus stops, where there is a transfer of power within seconds after a connection is established. This reduces the need of using large storage batteries. Apart from better efficiency, this is also likely to increase space within the bus.

3. Reliable Power Supply

 Power Electronics plays a crucial role in facilitating an integration between renewable power plants that are based on solar and wind power, It aims at ensuring a reliable and resilient power supply. As power from wind and solar sources can be intermittent there is a need for various applications to overcome this challenge. These applications stabilize current and voltage fluctuations and increase the productivity of the various industrial facilities the power supply caters to.

 Further advancements

We have already evidenced the flexibility and adaptability of Power electronics but with the energy systems of the future, there will be scope for further advancements.  This can be done through a three-pronged approach – semiconductor and systems design, ideating and implementing new applications, and digitalization. Semiconductors and systems will need to be designed to cater to a higher voltage, higher efficiencies, and higher currents depending on the applications. With more interconnected power grids there will be a need to ensure that power grid performance is maintained in the future. Advanced and effective applications may need to be developed such as integrating renewable energy for high-energy applications (for example, data centres). And last but not least innovative uses of Artificial Intelligence (AI) algorithms for system design, simulations of complex systems, evaluation and assessments.

According to Michael Hennessy, CEO of Wavelength Lighting, The future of energy can be summed up in two words: sustainable and renewable. Ensuring that future energy systems are effective, efficient, and resilient will largely depend on scalability across power and voltages, flexibility of control, and the speed with which supporting technologies develop.

How are hybrid inverters used in solar projects?

This paper proposes a new configuration of a single-phase hybrid inverter with an integrated battery energy storage, which is suitable for residential households to maximize local consumption of solar energy and thus reduce dependency on grid support. The hybrid inverter is called Direct Storage Hybrid (DSH) Inverter. A transformer-less topology such as HERIC, operating at low frequency to generate a three-level rectangular output voltage, is adopted to connect a photovoltaic (PV) panel to the load and/or the grid. A series active filter is employed to compensate the high harmonic components from the rectangular voltage and provide a sinusoidal voltage. A bidirectional dc/dc converter connects the battery to the PV panel to control the battery state of charge (SoC) and optimize the PV panel operation during both off-grid and grid-connected modes. The DSH inverter can let the battery bypass the dc/dc converter and connect directly to the inverter stage, leading to a significant improvement in throughput efficiency in battery utilization. This paper discusses the operation and loss analysis of the DSH inverter in off-grid mode.

This paper is designed in such a way that it overcomes this limitation by the use of solar energy. NA hybrid inverter lv with Solar Battery Charging System consists of an inverter powered by a 12V Battery. This inverter generates up to 230V AC with the help of driver circuitry and a heavy load transformer. This battery gets charged from two sources, first being the mains power supply itself and second from the solar power. If the mains power supply is available, then the relay switches to main power supply for supplying the load. This power supply also charges the battery for using it as back up the next time when there is a power outage. The use of solar panel to charge the battery gives an additional advantage of surplus power in case the power outage of mains is prolonging. Thus this inverter can last for longer duration’s and provide uninterrupted power supply to the user.

Hybrid inverters are commonly used in the developing world, but they are starting to make their way into daily use in certain areas of the U.S due to their ability to stabilize energy availability.

A solar inverter’s main job is to convert DC power generated from the array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. This type of system solves issues renewable energy variability and unreliable grid structures.

“Inverters for grid-tied applications can only provide power based on what the array can immediately generate from the sun,” explained Bryan Whitton, product manager at Darfon. “Hybrid inverters can store power in batteries and then drawn upon it as needed for energy stabilization.”

Hybrid inverters can vary in size, performance and features. But Mara White, product manager for OutBack Power, said most models usually operate bi-directionally, meaning they can convert DC power from modules to usable AC power and then convert stored AC from the batteries to power loads when needed. “Hybrids can also remain grid-connected and use a mix of renewable and non-renewable energy to charge batteries and offset loads,” White added.

Some contractors have used hybrid inverters in the residential, remote home applications for the past decade or two. But Allan Gregg, VP of applications engineering at GreatWall—which manufactures Satcon inverters—said the range of applications has expanded over the past few years to include large capacity microgrids as well as grid-connected systems.

Historically, hybrid inverters have been used more frequently in developing countries that do not have access to a reliable power grid.

“In North America and Europe, hybrid inverter-based systems are usually elective,” White explained. “Users choose to use them for storing energy for self-consumption or provide back-up power during emergencies. But in the developing world, hybrids are more of a necessity to compensate for weak or intermittent grids or a lack of grid electricity all together. Microgrids in places such as India, Asia and Africa are also driving na hybrid inverter hv adaptation.”

Still, Whitton said hybrid models are beginning to be used on a more daily basis in areas of the U.S. where the grid is unpredictable, such as Hawaii, or in states where net-metering has been widely supported. “Applications with less than ideal solar characteristic are also good for hybrid-based systems because they can store power and redistribute it during peak times, improving payback,” he added. “Basically, if the site has the potential for losing the grid frequently, you should consider a hybrid for off-grid operation.”

Having the flexibility of a hybrid system can add initial cost to a project, though experts say this can be offset by the ability to self-consume all of one’s available PV electricity.

There are also important design considerations when using hybrid inverters. For example, Gregg warned that the battery bank voltage should be compatible with the DC input requirements of the inverter, and there should be enough solar capacity to supply the load as well as charge the batteries.

Wiring can also be more complex when using hybrid inverters, especially when panels are dedicated for critical backed-up loads. “And as with any device that does several jobs at once, a hybrid inverter is usually slightly less efficient,” White added, “although, improvements in other balance-of-system components can compensate for that slight loss easily.”

There are also specific electrical safety issues with any type of energy storage, so White recommended getting specialized training in energy storage techniques and design. “Most available training is focused on simple grid-tied systems because they have been the majority of U.S. solar installations until now,” she said. “But with incentives changing and the surge in energy storage interest and applications, it’s important to get ahead of the curve and get advanced training quickly.”

Andrew McCalla of Austin, Texas-based Meridian Solar, a Solar Power World top contractor, said he commonly used hybrids in the mid to late ’90s when the now standard grid-tie inverter sector was just a glimmer. “I can imagine that, when regulatory hurdles are fabricated to limit the consumer and societal benefits of bi-directional power flow from distributed generation, these battery-based platforms will become far more common. What is old is new again!”

Another segment of hybrid inverters includes inverters that can use two energy sources. For example, Ginlong offers a PV / wind lv battery hybrid inverter that has inputs for both sources, instead of having to use two inverters. In much of the United States, wind speeds are low in the summer when the sun shines brightest and longest. The wind is strong in the winter when less sunlight is available. Therefore, because the peak operating times for wind and solar systems occur at different times of the day and year, such hybrid systems have the potential to produce power when it’s needed, and reach a higher return on investment.

When you first consider getting solar or battery storage on your home or business, one of the first things you will discover is that you will require an inverter and that there are many different types of inverters available. This article is designed to provide an introduction to the different kinds of inverters available and help you to understand which one will suit your installation. So what does an inverter do? Simply put an Inverter converts DC power to AC power. Solar panels produce DC power and batteries store DC, however most of our appliances run on AC power, as does the electricity grid. This is why all solar systems and battery storage systems need an inverter however there are several different types of inverters depending on whether or not energy storage batteries are required.

On-grid solar installations are the most common and most affordable type of system available at present. These systems use a simple solar inverter, which convert the DC power from your solar panels into AC power which can be fed directly into the grid, or used in your home appliances.

Off-grid and hybrid systems are much more complex because they involve both solar panels as well as battery storage. Multiple inverters are often required in these installations such as a solar inverter and sophisticated battery inverter/charger to manage both grid connection and the charging and discharging of the batteries. These advanced inverter/chargers are known as interactive or multi-mode inverters. However, in recent years a new type of inverter has become available which integrates solar and battery inverter technology into what is known as an all-in-one hv battery hybrid inverter.

A micro-inverter is a very small inverter that is attached to the back of a solar panel. A micro-inverter only converts the power of one or two solar panels to AC so generally many microinverters are required in a single system. Micro-inverters have several advantages over string inverters including performance, safety and monitoring, however the upfront cost can be significantly greater. For more details about micro-inverters, check out our micro-inverters article.

String solar inverters come in single phase and three phase versions although most residential homes in the US and Australia use single phase power, while many homes in Europe use 3-phase power, also all businesses and factories will have three phase power. As a general rule most String solar inverters between 1-6kW are single phase and greater than 6kW are usually three phase.

As home energy storage systems have surged in popularity a new kind of advanced Inverter has emerged known as an hybrid inverter. Hybrid inverters combines a solar inverter and battery inverter/charger into one simple unit. These inverters are a very economical way to enable what is known as ‘self-use’ or 'load shifting' of energy. Allowing you to store solar or off-peak energy in a battery to be used during peak times. Although it is important to know that some all-in-one inverters cannot function during a power outage such as when there is a blackout. They can also have limited functionality and monitoring capabilities.The traditional off-grid solar system uses a simple battery inverter that converters DC power from a battery bank to AC power to supply your home or appliances, these systems need separate battery chargers and regulators. There are more advanced versions of these battery inverters with built in chargers known as inverter/chargers. In recent years very advanced inverters have become available which are inverter/chargers with in-built generator control systems, advanced monitoring capabilities and other features, these are known as interactive or multi-mode inverters. They are typically used in conjunction with a solar inverter to create what is known as an AC coupled system. You can learn more about these and other hybrid inverter types here.

Tarin Highlights economic plans for 14 key sectors

Finance Minister Shaukat Tarin announced another short-, medium-, and long-term economic plan for 14 important industries on Friday, pledging not to quit the International Monetary Fund (IMF) program and instead of taking it to face-to-face negotiations in Washington in October.

Tarin also said the deadlock on Pakistan’s steel mills has been broken and that proposals will open in a few days for its official privatization process, speaking at a press conference with eight cabinet colleagues and private sector members of the Economic Advisory Council (EAC).

Mr. Tarin stated that performance in 14 areas will be reviewed beginning in September and that the prime minister would be briefed on the execution of the plans every month. “As a result, plans focus not just on developing strategies but also on guaranteeing execution, which is a significant departure from prior practice,” he added. He stated that while the present administration would be able to execute only short-term initiatives, some of which were already included in the current fiscal year’s budget, it would set the scene for future governments to follow.

The plan’s basic objectives include increasing overall economic growth from 3 percent to 6 percent over the next three years while keeping balance-of-payments pressures at bay and inflationary expectations low. It also involves raising the tax-to-GDP ratio by 1.5 to 2 percentage points per year, achieving a target of $30 billion in exports by FY 2023-24, and maintaining the momentum in international remittances.

The main goal is to provide a large number of job possibilities throughout time in order to involve the youth in productive areas of the economy.

Agriculture, including small farms, micro-enterprises, small and medium companies, construction, tourism, and information technology are the sectors highlighted for driving growth through the EAC platform. Mr. Tarin stated that this will be accomplished by policies that are logical, consistent, and well-coordinated among the federal, provincial, and private sectors.

Dr. Ishrat Hussain, Advisor to the Prime Minister on Institutional Reforms, stated that the roadmap would ensure export-led growth and strengthen the local government system because the devolution process under the 18th Amendment and the seventh National Finance Commission award had not been completed.

A multi-pronged plan for institutional changes in the public sector is included in the medium and long-term agenda, and provincial governments will prioritize attaining universal access to excellent education, health, safe drinking water, and sanitation.

Similarly, the federal and provincial governments would increase their emphasis on human development and build physical infrastructure that is behind in remote areas. The completion of China-Pakistan Economic Corridor projects, notably in agriculture, industrial cooperation, socio-economic development, and financial inclusion, is also part of the medium- to long-term planning.

It also involves the use of special technology zones, information technology parks, and incubation and entrepreneurship centers to supplement CPEC investments.

Long-term planning in the power and energy sectors includes executing the Renewable Energy Policy and the National Power Policy in order to achieve the target of 60% energy generation from non-fossil fuels, including hydropower generation.

The approach for tackling the circular debt problem involves lowering the cost of electricity generation by flattening the capacity payment curve through power producer restructuring.

Simultaneously, measures will be done to increase grid electricity demand by incentivizing captive-to-grid shift and the integration of NTDC-KE networks.

Farmers will be provided price guarantees and confirmed off takes as part of a multifaceted and multidimensional price stability plan to safeguard them from abuse at the hands of wholesalers and middlemen.

 What is the EDM machine meaning in the metal working industry

Electrical spark erosion, also known as electrical discharge machining and electrical corrosion machining, called electrical discharge machining in Japan and electrical corrosion machining in the former Soviet Union. It is a method of processing the metal workpiece by utilizing the phenomenon of electric corrosion generated during the pulse discharge between the two poles (electrode and workpiece, should be conductive). Academically it belongs to the category of electrophysical processing. EDM technology is one of the most important parts of special machining technology.

 What is the advantage of electrical discharging machining against traditional metal working method?

Answer: With the development of industrial production and the advancement of science and technology, more and more new materials with a high melting point, high hardness, high strength, high brittleness, high viscosity, high toughness, high purity and other properties continue to appear, and also some with various complex structures that can’t be machined by traditional metal working method, sometimes difficult or impossible to process. With traditional metal working technology.

 Therefore, in addition to further development and improvement of traditional mechanical metal working methods, people also strive to find new processing methods. The electrical discharging machining (EDM) method can meet the needs of development, and shows many excellent performances in the application, so it has been rapidly developed and increasingly widely used.

 Characteristics of EDM die sinking machining

(1). During machining, the tool electrode and the workpiece material are not actually touching and there is basically no macro-mechanical force between the two. Therefore, the "soft" tool electrode can be used to process the "hard" workpiece. For example, graphite and copper electrodes can process hardened steel, cemented carbide, and even diamond.

 (2). Because the spark energy density of the high-frequency power discharging can be accurately controlled, and there is no macro mechanical force between the two poles (electrode and workpiece), so the precise and fine machining can be achieved. Such as the processing of narrow slits, narrow grooves, micro-small holes of molds and parts, the processing accuracy can reach micron level, even sub-micron level.

 (3) "Copying". With direct use of electrical power for processing, it is easy to realize the automation, intelligence, and application of modern computer control technology to precisely control the machining process, which makes the machining of workpieces more realistic.

 (4) Direct use of electrical energy for processing, which is convenient for automation of the machining process, and can reduce mechanical processing procedures, shorten processing steps, low labor intensity, and easy to use and maintain

Solving India's Energy Access Crisis, One Innovation at a Time

Prime Minister Narendra Modi has set up an ambitious target of providing 24/7 access to electricity to every Indian citizen by 2019. Ministry of Power is aiming to provide grid connectivity to all villages by 2017 and has extended grid access to over 10,000 villages in the past year. 

Currently, over 200 million people in rural areas don't have electricity access and a similar number of citizens are suffering due to an unreliable grid and poor power quality. The Government of India is not alone in this quest to supply energy access to people at the bottom of the pyramid. 

Various entrepreneurs are testing the waters by introducing innovative off-grid solutions like solar lamps and renewable energy-powered microgrids in their effort to provide energy access for all. However, this sector is fragmented and unorganized leading to its inefficacy. 

This, in turn, is causing a roadblock for social and technological innovation at the very bottom of the social pyramid, leading to microgrids and related off-grid solutions becoming an expensive affair.

In this context, a need for a platform to bring transparency and innovation to the system has been recognized. Customized Energy Solutions, a leading energy services company, has developed an initiative under India Energy Storage Alliance (IESA) that looks to provide the rural consumer with affordable and reliable power. 

The Micro-grid Initiative for Campus and Rural Opportunities (MICRO/ https://micro.ces-ltd.com/) is an international initiative that has set a goal of reducing the cost of electricity in rural microgrids by 30-50% within the next 3 years through innovation and collaboration across stakeholders.

The MICRO team believes that microgrids in India have vast potential to transform the economic landscape in rural India as well as provide improved power quality for consumers in urban townships to critical infrastructures like hospitals and university campuses. To achieve this dream, the sector would need to be organized.

At the heart of MICRO lies an IoT (Internet of Things) based portal which incorporates a remote monitoring platform with supply, demand, and funding aggregation capabilities. The portal is a unique multi-stakeholder platform that allows the industry to work as a bazaar where different stakeholders like project developers (or ESCOs), funding agencies, and equipment suppliers can communicate with each other, realize future business opportunities, and validate the performance of current assets. 

MICRO is looking to involve a variety of stakeholders, namely technology providers, regulators, microgrid developers, end-users through local not-for-profit organizations, and Funding Agencies in its effort to make microgrids techno-commercially sustainable and link electricity to economic development.

MICRO is supported by the Alliance of Rural Electrification (ARE), Global Energy Storage Alliance (GESA), and Rang De and has received USAID's prestigious PACESetter Award for innovative clean energy initiative. The MICRO portal (www.micro.indiaesa.info) will be launched at a workshop at IIT Bombay on 19th August 2016.

The India Energy Storage Alliance (IESA) was launched in 2012 by Customized Energy Solutions to promote energy storage and microgrid technologies and their applications in India. 

IESA does this by creating awareness among various stakeholders to make the Indian industry and power sector more competitive and efficient, and by promoting information exchange with the end-users to assist with more informed decision-making. 

IESA also provides insights to technology developers and system integrators on the policy landscape and business opportunities in India through frequent interaction with key stakeholders.

Analyze your device's air filters at the time a month and thoroughly clean or substitute filters when important. Calling in another person to complete the maintenance can Expense upwards of $100 - this is surprisingly easy to carry out oneself (study the appliance guide or look for Google for your tips on how to), substitute filters Price below $ten, so a double conserving.

Retaining your filters thoroughly clean may be the minimum expensive thing you are able to do to maintain your devices and might Lower Strength consumption from 5 to 15%.

FAN-tastic

Lovers can make the temperature feel 10 levels cooler, minimizing your need to have for AC. Ceiling followers are somewhat cheap to buy and put in and are available in all method of various styles and modes. They use hardly any energy; a normal flooring lover works by using 100 watts of electrical energy and ceiling followers as minor as 15 to 95 watts at the best velocity (which is among the most economical speed for cooling you). That is even a lot less than a Coffee maker which utilizes involving 500 and 800 watts.

The Barrington Eco Hut is designed by Fresh Prince, a design and building practice with a particular passion for designing tiny eco houses. The firm is committed to exploring how small dwellings can allow Australians to spend time in remote, picturesque locations, without disturbing the surrounding environment.

Barrington Eco Hut is the practice’s latest tiny project. You’ll find no phone reception or Wi-Fi here, just 14 square metres of interior space (less than a third of the size of a typical one-bedroom city apartment!) and the surrounding riverbanks.  The brief from the client was simply to create a self-contained, off-grid cabin with minimal impact on the environment. 

While many architectural projects take years to come to fruition, the entire design and building process was completed in about six months, with the use of prefabricated construction.

‘Prefabricated construction is great for remote sites because the construction process can be streamlined without the hassle of getting materials and tradespeople to and from the site,’ says Fresh Prince director, Alice Nivison. ‘We love it because it also means we have a centralised space where we design and build, the materials are looked after and off-cuts are stored for later reuse, and we can work in any weather.’

The design of this particular project was tailored to its specific site in Barrington Tops, NSW, about two hours drive north-west of Newcastle. 

‘Although the general orientation was preconceived, the prefabricated nature of the cabin allowed us to manoeuvre the dwelling on site, making micro adjustments to capture the best views and ambience in real time, and find the perfect spot,’ says Alice. 

Eschewing a ‘cookie cutter’ design approach, Fresh Prince began the design process from scratch in order to determine what was truly essential. The resulting project frames the surrounding views from the living and sleeping areas, with a more private outlook towards the adjacent woodland from the bathroom. Double doors open out towards the river, creating a feeling of expansiveness despite the dwelling’s tiny interior footprint. Continuous built-in joinery also removes the need for additional furniture.

Among the eco-friendly features of the cabin are an integrated off-grid solar system, rigid foam insulation that creates minimal air gaps (as wool insulation can shift during transport and over time, causing weak spots in the thermal performance), a composting toilet; and carbon-neutral Weathertex exterior cladding. 

‘We hope that through exploring these tiny designs, we can inspire people to rethink the amount of space they need in their homes, and through this, live a more simplified life,’ Alice says. 

The Barrington Eco Cabin has recently welcomed its first guests. Find out more here.

via Today Bharat Loan limits for renewable energy, health infrastructure doubled The RBI has also brought loans to farmers for installation of solar power plants for solarisation of grid-connected agriculture pumps. The Reserve Bank of India (RBI) on Friday brought financing of start-ups under the priority sector lending (PSL) category of the banking sector, proposed more credit flow to districts with lower PSL, and doubled loan limits for renewable energy and health infrastructure “to align it with emerging national priorities and bring sharper focus on inclusive development.” In a bid to address regional disparities in the flow of priority sector credit, the RBI, in its revised PSL guidelines, decided to rank districts on the basis of per capita credit flow to the priority sector, and build an incentive framework for districts with lower flow of credit and a disincentive framework for districts with higher flow of priority sector credit. Explained: What counts as ‘Act of God’? Accordingly, from FY 2021-22 onwards, a higher weight (125 per cent) would be assigned to the incremental priority sector credit in the identified districts where the per capita PSL is less than Rs 6,000, and a lower weight (90 per cent) would be assigned for incremental priority sector credit in the identified districts where the per capita PSL is more than Rs 25,000. As many as 184 districts with low per capita PSL credit flow will benefit from the RBI move. A higher credit flow to the rural sector is expected to boost rural spending at a time when GDP growth has contracted by 23.9 per cent in the June quarter. EXPLAINED Targeting the flow of credit The RBI move, which comes at a time when credit growth has remained sluggish at 6.7% and GDP for the first quarter contracted by 23.9%, is aimed at enabling better credit penetration to credit deficient areas, increasing the lending to small and marginal farmers and weaker sections and boosting credit to renewable energy and health infrastructure. The RBI has also brought loans to farmers for installation of solar power plants for solarisation of grid-connected agriculture pumps, and loans for setting up compressed bio gas (CBG) plants as fresh categories eligible for finance under the priority sector. In a push to the start-up sector, the central bank said loans up to Rs 50 crore can be availed by start-ups — as per the definition of the Ministry of Commerce and Industry — that are engaged in activities other than agriculture or micro, small and medium enterprises (MSMEs). Commercial banks, including foreign banks, are required to mandatorily earmark 40 per cent of the adjusted net bank credit for priority sector lending. Regional rural banks and small finance banks will have to allocate 75 per cent of adjusted net bank credit to PSL. The central bank said the changes “will enable better credit penetration to credit deficient areas, increase the lending to small and marginal farmers and weaker sections and boost credit to renewable energy, and health infrastructure”. Doubling the loan limits for renewable energy, the RBI has said bank loans up to a limit of Rs 30 crore to borrowers for purposes like solar-based and biomass-based power generators, windmills, micro-hydel plants, and non-conventional energy-based public utilities – such as street lighting systems and remote village electrification — will be eligible for priority sector classification. For individual households, the loan limit will be Rs 10 lakh per borrower, the RBI said in a notification to commercial banks. The RBI has doubled the credit limit for improvement of health infrastructure, including those under Ayushman Bharat. Bank loans up to a limit of Rs 5 crore per borrower for setting up schools, drinking water facilities, and sanitation facilities including the construction and refurbishment of household toilets and water improvements at household level; and up to a limit of Rs 10 crore per borrower for building healthcare facilities including under ‘Ayushman Bharat’ in Tier II to Tier VI centres, have been allowed. The RBI said it has increased the targets prescribed for small and marginal farmers, and weaker sections. “The applicable target for lending to the non-corporate farmers for FY 2020-21 will be 12.14 per cent of the adjusted net bank credit or Credit Equivalent of Off-Balance Sheet Exposures (CEOBE) whichever is higher. All efforts should be made by banks to reach the level of 13.5 per cent of ANBC (erstwhile target for direct lending to agriculture sector),” it said. While the rate of interest on PSL varies from sector to sector, it’s considered cheaper and more accessible when compared to normal loans. The rate of interest on bank loans will be as per directives issued from time to time by the Department of Banking Regulation of the RBI. Priority sector guidelines do not lay down any preferential rate of interest for priority sector loans. The RBI said a higher credit limit has been specified for farmers producers organisations (FPOs) and farmers producers companies (FPCs) undertaking farming with assured marketing of their produce at a pre-determined price. Loans for these activities will be subject to an aggregate limit of Rs 2 crore per borrowing entity. The RBI said it has comprehensively reviewed the PSL guidelines to align it with emerging national priorities, and bring sharper focus on inclusive development, after having wide-ranging discussions with all stakeholders. “Revised PSL guidelines will enable better credit penetration to credit deficient areas, increase the lending to small and marginal farmers and weaker sections and boost credit to renewable energy and health infrastructure,” the RBI said. According to the RBI, to address regional disparities in the flow of priority sector credit, higher weightage has been assigned to incremental priority sector credit in “identified districts” where priority sector credit flow is comparatively low. It has defined farmers with landholding of up to one hectare as marginal farmers, and farmers with a landholding of more than one hectare and up to 2 hectares as small farmers. The RBI last week said on a year-on-year (Y-o-Y) basis, non-food bank credit growth at 6.7 per cent in July 2020 was lower than the growth of 11.4 per cent in July 2019.
