Cleaning The power output of a solar panel is proportional to the amount of sunlight that reaches
Solar the solar cells. Therefore, any build-up of dust or dirt on the surface of the solar panel will
Panels result in a loss of power. This is a trade-off between the maximizing the power output of
the solar panel versus the cost and time to perform regular cleaning.

there is a build-up of dust or dirt on the surface of the solar panel, it is
recommended to clean it.

is cooler, especially in hot regions. This will reduce the risk for electrical and
thermal shock.
