What about maintenance?

In most areas of the state, there is sufficient rain to clean the panels. However, if you are in a dusty area (very near a busy dirt road, very urban area, etc.) you may see a performance gain from cleaning the panels monthly. If necessary, a hose stream is usually sufficient for cleaning.

• Do not walk on or over the panels to clean them.
  
• Do not use metal, hard, or abrasive methods for cleaning.
  
• Do not spray water on the panels when they are very hot.
