It increases efficiency

Besides damaging your solar panels, grime and dirt also affect their efficiency. It prevents direct sunlight, essential for energy production, from reaching the panels.

That’s why some users suddenly experience poor performance of these solar panels. It is bound to continue as long as enough sunlight doesn’t penetrate the photovoltaic cells.

Commercial generation is affected by up to 61%. The domestic one is affected by around 21% due to unclean panels. Don’t let it happen to you since it is avoidable by cleaning them regularly.

It boosts your warranty validation

If you don’t follow the set conditions, solar panel installation companies and manufacturers won’t consider your warranty. That’s why you need to follow them strictly to avoid such instances.
