Automatic Solar Panel Cleaning

Keeping the Solar panels clean is very important in a rooftop solar PV setup. A dirty solar panel reduces efficiency and can also cause hot-spots on the solar panels.
In most of our projects, to avoid shadow effects, we elevate the structure. However, with elevated structure, cleaning of the panels becomes difficult. So a walkway is provided between solar panels for easy accessibility.
In spite of a walkway, due to various reasons like paucity of time or due to non-availability of manpower, one needs to have an automatic solar panel cleaning system.
In this video, we have shown one such system where the solar panels get cleaned automatically every day.
