Should Solar Panels Be Cleaned in 2025?

The secret of sustainability is to keep solar panels. Although the design of solar panels is that of combating the elements, dust, pollen and salt accumulation can slowly diminish their performance. The optimal solar panel maintenance schedule is reliant on your surroundings and installation layout.

Urban homeowners should consider cleaning their houses once in 6 months since the dirt and rubbish from the surrounding traffic can settle on the panels. Cleaning at least once in 3-4 months is recommended in rural or dusty areas where the wind and soil particles are rather frequent and contribute to keeping the output at the maximum. In the meantime, there are other challenges observable on coastal regions, salt accumulation may corrode surfaces and thus it is highly advisable to have a quarterly cleaning to safeguard your investment.

The frequency of cleaning the solar panels does not fit all cases. Regular inspections and a basic record of maintenance allow you to tune frequency to the weather conditions and the changing of the season so that your system will be effective throughout the year.

How to Clean Solar Panels Safely? A Step by Step Guide
