Most of our customers do not clean their panels. In most areas of the country, there will be sufficient rain to clean the panels. However, if you are in a dusty area (near a busy dirt road, a very urban area, etc…) you may see a performance boost 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.
