Why Solar Panels need cleaning
Solar panels work by allowing light into the solar cells. The more light that hits a panel, the more power it will generate. Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So it is important to clean solar panels in order to protect and maintain your investment.
Example of cleaning efficiency
In California, technology giant Google has a 1.6 mW solar panel installation. The research they carried out on their own equipment reached a clear conclusion that dirty solar panels will have a negative impact on their performance. Fifteen months after their solar panel array had been installed; they experimented with solar panel cleaning. After the first session of solar panel cleaning, their output doubled on some solar panels. Eight months later, they had their second session of solar panel cleaning and the solar panel efficiency increased again by 32%. After having solar panel cleaning, all of Google's solar panels increased their output by at least 12%. The goal of Clear-Sol is to come across as genuine and honest
