The leading European countries have been pursuing a competent policy in a field that is new to us for a long time and have already achieved some success. Germany, Sweden, and Australian residents can use and sell their sources.

Principle of operation:

• rays fall on the surface
• light is absorbed
• it is converted into electrical current.

The more rays hit the surface, the higher the efficiency. And if they are not? The panel does not work, and energy is not generated. This is not true.

Cloudy performance

In bad weather, solar modules can generate electricity. It's just how dark it is outside. After all, panels are capable of absorbing direct rays and diffused light.

The efficiency will decrease, but it will not be as critical as many think. Depending on the degree of cloudiness, on average, it reduces by 10-25%.

I want to note the detail that must be considered during installation. The roof of the house where the solar system's structure is planned should not be in the shade. It will help if you rid everything that gives this shadow: extra trees, buildings, towers. Or move the installation to another location. This will provide you with a more efficient operation of the mini power plant.

As for precipitation in the form of rain and snow, they reduce efficiency, but generally, they do not affect the operation globally. If it's raining but sunny, the panels will store energy steadily. When operating in winter, it is important to install the installation correctly, set the slope correctly (remember, in winter, the sun is slightly lower than in summer), and regularly clean snow and ice.

Do batteries work at night?

There is no sun, so the battery does not work out. Modules do not work at night. There are two options here: either, as soon as the batteries go into standby mode, you will need to connect to the public network and take energy from there. Or use batteries that can accumulate when it is light and then give it away.

Thus, at night, in winter, and at any moment when there is not enough light to get enough energy, based on solarsystems.reviews,  batteries will come to your aid, where the reserve is stored. Rechargeable batteries are also advisable in case of permanent power outages.

Use in different countries

You will not believe it, but, for example, Germany is a rather cloudy country. However, it was there in 2006 that the world's largest fleet of power plants opened. Cloudy, rainy weather prevails in many US cities. This is in San Francisco, Seattle, and Boston. But solar energy continues to develop there and does not give up its position.

In addition, remember that solar energy is constantly developing, technologies are improving, and modules are becoming more efficient year by year, showing the best efficiency, such as solar powered inventions. And besides, their cost is reduced, which also affects the activity of the population in their installation and operation.

Many scientists are developing modules that will absorb even at night. While numerous developments are underway, experiments are being done, but hopefully, they will soon appear on the market.
