Best 3 Type of weight loss belts you should know and Do they Work?

Stress, hectic lifestyle and poor eating habits are the main reasons behind sudden or prolonged weight gain. With less time to exercise and a lack of open spaces, physical activities are becoming more restricted. This also leads to weight gain. However, with the advancement of technology, losing weight and getting a well-toned, fit, and healthy [...]

How does a solar charger work?

A solar charger is formed by one or several solar panels. Each panel or solar panel is composed of small photoelectric cells, usually made of silicon (material suitable for transmitting electrons), which can be high quality monocrystalline or polycrystalline, with lower quality and lower results.

One of the most significant limitations of these solar panels, apart from the material used to manufacture them, is the small amount of energy they collect per individual cell.

photovoltaic cells solar panel purchase guide That is why you would need to use large panels (which would be impractical in our case) or, what is usually done, connect several small groups in parallel that are later deployed to capture more solar radiation.

Types of solar panels: Monocrystalline vs Polycrystalline When deciding on a solar panel, most users ask themselves this question, which is the best? If we want to know, we must bear in mind that the performance of a solar panel will decrease as the temperature increases.

Monocrystalline panels: They are the ones that attract the most radiation when they have a darker colour cell. This makes them more recommendable for cloudy or low radiation days.

Polycrystalline panels: They are more bluish in colour and reach lower temperatures, so there is less loss of performance and is recommended for days of full sun.

monocrystalline vs polycrystalline panel There is, therefore, no perfect solar panel for every day. If we make an annual average, we will have better behaviour in a monocrystalline solar plate in the months of low solar radiation and worse in the months of higher radiation to give an example.

The solar chargers of the brands that we recommend work with monocrystalline panels from the SunPower manufacturer that have efficiency in their groups of more than 20%.

Therefore, when deciding on a solar charger, the significant thing is that we look for the one with the best price, quality and use needs, without giving more importance than necessary if the panel is made of a material or another.

According to the power (W), what solar charger should I buy? The higher the power output of the solar charger, the faster the connected devices will charge since the USB ports will have a higher capacity to satisfy the power demand of each connected device.

However, two key factors must be taken into account:

Devices that you will use with the solar charger It is the first question you should ask and be clear: what and how many tools do you plan to use with the charger?

It is convenient to know this because the prices of solar chargers vary greatly depending on the power that can be supplied.

That is if you are going to recharge 2 or 3 at the same time you are interested in buying a solar charger with a higher power. On the other hand, if its use is occasional and for a single device such as a mobile phone with a charger of between 15-20W it would be more than enough for a fast charge.

How the sun's rays strike the solar panel Assuming a sunny day, to have a good performance and, therefore, more power at the exit you have to place the solar panels so that the rays strike perpendicularly on them
