One of the major problems in Solar PV system is the cleaning of the solar panels .
Even if the panels are maintained regularly by cleaning with water, the dust sometime settles at the bottom edge of the panels resulting in hot spot formation .

In this video, we have tried to show how to restore the affected PV glass and also a simple technique to prevent water stagnation at the bottom of the panels.
