Why do solar panels need cleaning?

Solar panels consist of tiny photovoltaic cells that convert the sun’s energy into usable electric energy. However, since solar panels are installed outside in open spaces, over some time, these photovoltaic cells may get blocked by debris, dirt, or even bird droppings.

A study by the National Renewable Energy Laboratory states that soot, dust, and debris can decrease solar panel efficiency by 7%. Thus, for optimal solar panel functionality, you need to clean these panels periodically. However, getting a professional to clean your panels might not always be feasible and may also prove to be costly, especially when you need periodic cleaning.

This is where DIY solar panel cleaning comes into play. You can easily clean your solar panels with some DIY tools and negate the need for professional cleaning.
