Solar Panel Maintenance And Cleaning


Purchasing a solar panel system is a valuable investment. Solar panels become dirty because of dust and pollution. Thus, to ensure the longevity of your solar system, solar panel maintenance, and solar panel cleaning is necessary. 

The efficiency of solar panels closely depends on the cleanliness of panels. In case there is debris on the solar panel, it is going to produce less electricity and reduce the profitability of the system. 

Solar Panel Annual Maintenance

Solar panel maintenance is the technical maintenance of the solar panels. It should take place once a year. 

Generally, solar panels are durable. They need little maintenance over their productive life of about 25 years. If you clean them periodically and make sure they do not get dirty, they are going to function long. Rain clears the dirt and leaves out of panels as well. So, during the dry season, you have to clean the panels yourself. Solar panels’ cleaning is needed not more than four times yearly.

Solar panel systems come with a warranty that covers replacement and repair costs. In case you lease the system, the maintenance is not under your responsibility anymore.

Installing ground panels instead of roof panels will make it easier for you to keep them clean. Another relevant tip about solar panel maintenance is keeping the panels out of shade. In the shade, solar panels become inefficient as they do not receive sunlight. 

You can check your solar panel with a solar panel monitoring system. The system will help you track the energy produced and alert you in case of breaks.
