"As solar panels heat up beyond 25°C, their efficiency decreases markedly. Green roofs moderate rooftop temperatures. So we wanted to find out: could green roofs help with the problem of heat reducing the output of solar panels?

Our research compared a “biosolar” green roof — one that combines a solar system with a green roof — and a comparable conventional roof with an equivalent solar system. We measured the impacts on biodiversity and solar output, as well as how the plants coped with having panels installed above them.

The green roof supported much more biodiversity, as one might expect. By reducing average maximum temperatures by about 8°C, it increased solar generation by as much as 107% during peak periods. And while some plant species outperformed others, the vegetation flourished.

These results show we don’t have to choose between a green roof or a solar roof: we can combine the two and reap double the rewards...

How did the panels affect the plants?

In the open areas, we observed minimal changes in the vegetation cover over the study period compared to the initial planted community.

Plant growth was fastest and healthiest in the areas immediately around the solar panels. Several species doubled in coverage. We selected fast-growing vegetation for this section to achieve full coverage of the green roof beds as soon as possible.

The vegetation changed the most in the areas directly below and surrounding the solar panels. The Baby Sun Rose, Aptenia cordifolia, emerged as the dominant plant. It occupied most of the space beneath and surrounding the solar panels, despite having been planted in relatively low densities.

This was surprising: it was not expected the plants would prefer the shaded areas under the panels to the open areas. This shows that shading by solar panels will not prevent the growth of full and healthy roof gardens.

What were the biodiversity impacts?

We used environmental DNA (eDNA) surveys to compare biodiversity on the green roof and conventional roof. Water run-off samples were collected from both roofs and processed on site using portable citizen scientist eDNA sampling equipment to detect traces of DNA shed by the species on the roof.

The eDNA surveys detected a diverse range of species. These included some species (such as algae and fungi) that are not easily detected using other survey methods. The results confirmed the presence of bird species recorded by the cameras but also showed other visiting bird species went undetected by the cameras.

Overall, the green roof supported four times as many species of birds, over seven times as many arthropods such as insects, spiders and millipedes, and twice as many snail and slug species as the conventional roof. There was many times the diversity of microorganisms such as algae and fungi.

Encouragingly, the green roof attracted species unexpected in the city. They included blue-banded bees (Amegilla cingulata) and metallic shield bugs (Scutiphora pedicellata).

How did the green roof alter temperatures?

The green roof reduced surface temperatures by up to 9.63°C for the solar panels and 6.93°C for the roof surfaces. An 8°C reduction in average peak temperature on the green roof would result in substantial heating and cooling energy savings inside the building.

This lowering of temperatures increased the maximum output of the solar panels by 21-107%, depending on the month. Performance modelling indicates an extensive green roof in central Sydney can, on average, produce 4.5% more electricity at any given light level.

These results show we don’t have to choose between a green roof or a solar roof. We can combine them to take advantage of the many benefits of biosolar green roofs.

Biosolar roofs can help get cities to net zero

The next step is to design green roofs and their plantings specifically to enhance biodiversity. Green roofs and other green infrastructure may alter urban wildlife’s activities and could eventually attract non-urban species.

Our green roof also decreased stormwater runoff, removed a range of run-off pollutants and insulated the building from extremes of temperature. A relatively inexpensive system provides all of these services with moderate maintenance and, best of all, zero energy inputs.

Clearly, biosolar green roofs could make major contributions to net-zero cities. And all that’s needed is space that currently has no other use."

Europe’s largest rooftop farm, Nature Urbaine in Paris, can produce 10 tons of produce each season. 

Hundreds of immaculate white columns dotted with small cylindrical outlets cover the rooftop of the Paris Expo Porte de Versailles exhibition center in the south of the French capital.

Fragrant basil, scarlet strawberries and unwieldy masses of dark green kale are among the colorful produce sprouting from each of the holes, which form part of a soil-less farming device known as an aeroponic growing tower.

“You see, there’s nothing in there,” says Eugénie Mercier, pulling out a bunch of kale to reveal its roots dangling freely inside the plastic structure. “When we water them, the plants take what is needed and we recycle the leftover water, so none is wasted.”

Mercier is manager of Nature Urbaine, Europe’s largest urban rooftop farm, which opened in spring 2020. At 14,000 square meters (150,000 square feet), its surface is almost as large as the playing area of the Stade de France football pitch not far away, and it can produce more than 10 tons of fruit and vegetables per season, using neither pesticides nor soil. According to manufacturer Agripolis, its computer-controlled hydroponic and aeroponic systems use 80% less water and produce 62% fewer CO2 emissions than a conventional farm for the same yield. Last year it was recognized by Ecocert, a French certification organization, as the first urban farm in the world to net offset carbon.

“It’s not just greenwashing,” adds Mercier. “This will really benefit the planet.”

In recent years, customer complaints about rooftop solar have increased. Across the country, prosecutors are investigating high-pressure sales tactics and misleading financing arrangements. Some customers say they were victims of fraud and forgery. The Consumer Financial Protection Bureau recently warned solar customers about hidden fees and deceptive statements about the financial benefits of solar. But what if you want solar now? Here are some things to consider.

In 2015, two geographers noticed solar panels popping up on houses in their small US state of Connecticut. Curious, they set out to see if they could figure out what predicted who had them. Would they be in richer homes? Or in areas with higher population density?

Early adopters of solar panels tend to be people who are interested in innovative technology, who find an installer they trust, and who think having solar panels will benefit them. But once an early adopter made their choice, the geographers found, a cluster would spring up around them. Having solar panels on a house near you, where you could see them and talk to a real live person who had them, it turned out, was the biggest predictor of whether you’d get them yourself. 

Why? Because it brought down the “cost” of information. You didn’t have to go somewhere or find a new person to talk to; they were right there beside you and ready and eager to bend your ear with all the information you needed to make the same choice they had.

Embracing Clean Energy: A Comprehensive Guide to Solar Systems for Homes

In today's world, the shift towards renewable energy has become a necessity rather than a choice. Solar energy, with its abundant availability and eco-friendly nature, is one of the most popular options for sustainable living. For homeowners looking to reduce their carbon footprint and energy bills, installing a solar system for home is an ideal solution. This blog explores the benefits, considerations, and types of solar systems that can help you make an informed decision.

Why Choose a Solar System for Your Home?

The primary advantage of installing a solar system at home is the significant reduction in electricity bills. Solar energy harnesses the power of the sun to generate electricity, which means less reliance on conventional sources. Over time, this results in substantial savings, making it a smart long-term investment. Besides financial benefits, a solar system also contributes to environmental preservation by reducing greenhouse gas emissions.

Moreover, in places with ample sunlight like Pune, solar power is a highly viable option. With the help of professional solar companies in Pune, you can install efficient systems that cater to your specific energy needs.

Components of a Solar System for Home

A solar system consists of various components that work together to generate electricity. These include:

Solar Panels: The most visible part of a solar system, solar panels convert sunlight into electricity. They are installed on rooftops to capture maximum sunlight.

Inverter: The inverter converts the direct current (DC) produced by the solar panels into alternating current (AC), which is usable by most household appliances.

Mounting Systems: These are used to secure solar panels to the roof. The design and placement of mounting systems are crucial for optimal sunlight exposure.

Battery Storage (Optional): Some homeowners opt for battery storage to store excess energy produced during the day, which can be used at night or during cloudy conditions.

Monitoring System: Many solar systems come with monitoring tools that allow homeowners to track the energy production and consumption.

Types of Solar Systems for Homes

There are different types of solar systems to choose from, each with its unique features:

On-Grid Systems: These are connected to the main electricity grid. Excess power generated can be fed back into the grid, and homeowners may receive credits from the utility company.

Off-Grid Systems: These systems are entirely independent of the grid and typically include battery storage. They are suitable for homes in remote areas or those looking for complete energy independence.

Hybrid Systems: A combination of on-grid and off-grid systems, hybrid systems use both grid electricity and battery storage, offering more flexibility.

Solar Rooftop System for Homes

A solar rooftop system is the most common method for homeowners to integrate solar power. These systems are designed to be installed on the roof of a building, making use of the available space. They are especially popular in urban areas like Pune, where rooftops provide an ideal surface for solar panels.

One of the benefits of a rooftop system is that it doesn’t require extra land, making it cost-effective for urban homes. Additionally, a well-designed rooftop system can blend seamlessly with the architectural aesthetics of your home.

Solar companies in Pune offer various services that include designing, installing, and maintaining solar rooftop systems, ensuring that the system operates at optimal efficiency. With the right guidance and professional installation, a rooftop system can significantly cut down your electricity expenses and help you move towards energy independence.

Things to Consider Before Installing a Solar System

Before making the decision to install a solar system, there are several factors to keep in mind:

Energy Needs: Evaluate your household's energy consumption to determine the size of the solar system required.

Roof Condition: Your roof must be in good condition to support a solar installation. It’s advisable to have an expert inspect the roof to ensure it can handle the weight of the panels.

Sunlight Exposure: For maximum efficiency, your home should receive adequate sunlight throughout the year. Shaded areas may reduce the effectiveness of the system.

Budget: While solar systems for homes are an investment, they have varying price ranges. It’s important to factor in initial costs and potential savings over time.

Switching to a solar system for home is a smart decision that offers both financial and environmental benefits. Whether you're looking to install an off-grid or solar rooftop system, solar companies in Pune provide a wide range of solutions tailored to your needs. As the world continues to prioritize sustainability, there has never been a better time to embrace solar energy for your home. With proper planning and professional installation, you can enjoy long-term savings and contribute to a greener future.

"Passed in February [2024], a massive subsidy program to help Indian households install rooftop solar panels in their homes and apartments aims to provide 30 gigawatt hours of solar power to the nation’s inventory.

The scheme, called PM-Surya Ghar, will provide free electricity to 10 million homes according to estimates, and the designing of a national portal—a sort of Healthcare.gov for solar panels—will streamline the process of installation and payment.

The program was cooked up because India had fallen woefully behind on its planned installations for rooftop solar. In many parts of the subcontinent, the sun is absolutely brutal and relentless, but by 2022, Indian rooftop solar power generation topped out at 11 gigawatts, which was 29 gigawatts under a national target set a decade ago.

Part of the challenge, Euronews reports, is that approval from various agencies and departments—as many as 21 different signatures in some cases—was needed to place a solar array on your house. Aside from this bureaucratic nightmare, the cost of installation was often higher than $5,000; more than half the average yearly income for a working Indian urbanite.

Under PM-Surya Ghar, subsidies for a 2-kilowatt solar array will cover as much as 60% of the installation costs, falling to 40% for arrays 3 kilowatts or higher. Loans set at around 7% interest rates will help families in need get started. 750 billion Indian rupees, or $9 billion has been set aside for the project.

Even in New Delhi, which can be covered in clouds and smog for days, solar users report saving hundreds during summer time on their electricity costs, with one apartment shaving $700 every month off energy bills.

PM-Surya Ghar is also seen as having the potential to cause a boom in the Indian solar market. Companies no longer have to go running around for planning and permitting requirements, and the government subsidies ensure their customer base can grow beyond the limits of household income."

Before the war in Ukraine, the EU solar energy market was expected to increase around 33 GW per year according to last year’s analysis by Statkraft. Now, in the new 2022 analysis, the company published an estimated average yearly increase of solar capacity in the EU of between 45 and 52 GW by 2030. Solar power is more cost-efficient than other renewable energy technologies, and construction can take less than two years.

Solar power is seen as the biggest winner in the energy transition. According to the report, it will become the world’s largest source of power generation around 2035(..)

P.S. The war started by the Russians in Ukraine against Europe and the West will significantly accelerate the collapse of the fossil fuel industry.  It is clear to practically everyone that fossil fuels are NOT a safe and reliable energy source and that replacing them with other energy sources as soon as possible is in the interests of European security and economic well-being...
