Solar panel cleaning
A solar panels is a complex device that allows you to convert light energy into electrical energy. And the more light hits its surface, the more power it will generate. The panels are located at a certain angle to the sun and because of this they are prone to the accumulation of various pollution. Bird droppings, general pollution, smog, dust, grass clippings, etc. pollution reduces the amount of light reaching the panel and, accordingly, the generation of electricity at the output (which is declared by the manufacturers). The second important factor in the need for cleaning is the premature degradation of the crystals, and then the panel as a whole. In the long run, this is lost revenue.
Therefore, it is very important to keep the surface of the solar cells clean so that the electricity generation corresponds to the forecast.

Don't use hard brushes to clean the glass - they can scratch the surface
Avoid aggressive chemicals, glass does not always react good to them
Before mechanical cleaning, the panels should be poured with water without contact with cloths and brushes;
With the help of soft brushes, it is necessary to remove the main dirt, simple chemicals can be applied
To make the solar cells last longer, you can use professional chemicals. It has a special composition that doesn't damage the transparent surface.
Using an ordinary broom or a hard brush will lead to the fact that due to scratches and minor damage to the protective surface.
The main cleaning recommendations are:
Why doesn't rainwater clean your solar panels?
A good way to show why rainwater doesn’t clean solar panels is to look at your car’s windshield. If you don’t clean your windshield for 6 months, how much visibility will you lose? If left, dirt will build up on the windshield and eventually turn “green.” Even if the car waits, the rain contains airborne dust particles that settle and attach to the surface after the rainwater evaporates. All of your solar panels are in the same condition as the edge of your car windshield because they are both exposed to the same elements.
Visibility through the windshield is lost due to light loss. Therefore, the same principles apply to cleaning solar panels. It is very important to maximize the light reaching the solar panel and, in turn, increase the financial reward.
