A review of how to maintain your solar equipment.
Because PV systems have no moving parts, regular maintenance is straightforward for a consumer. First, make sure you have enough rain each year to wash the panels. If you live in a desert or a dusty environment, periodic cleaning is recommended once per year with distilled water. The same is true if you are located near the ocean and receive marine mist that could leave salt deposits.
You should also be sure to keep nearby trees trimmed, as any overgrowth that increases shading on your panels can negatively impact your system's performance.
If your system is not working properly, call customer support. Never attempt to repair the system yourself.
