Maintaining Your Solar Panels: How Easy Can It Get?

A common misconception among many homeowners who have installed, or are considering the installation of solar panels at their homes, is that these systems are free of maintenance.
This is not strictly true. Even though your solar panels have no moving parts, they do require at least a minimal amount of house cleaning, even here in the sunny Arizona climate.

Since solar panels sit  in the open here in Central Arizona, they are constantly exposed to  airborne dust, tree residue, insects and birds. The longer that dirt and other contaminants are allowed to accumulate on your solar panels, the less efficient your panels will operate. In order for the sun’s rays to penetrate the solar cells, you must eliminate the dirt or lose up to 7 percent of your system’s efficiency.

Solar panels are engineered to last dozens of years. Maintaining solar panels should be done at least annually, or up to four times a year, depending  on the amount of dust in your neighborhood. The good news is that maintaining solar panels is an easy do-it-yourself project. It only requires that you give your panels a good rinsing with a garden hose. If you live in an area where agricultural or construction dust is a problem, a mild, non abrasive cleaning agent can be applied before rinsing. Plan on clean the panels in the early morning before the sun heats up.

Periodically, ask your installer to check the fuses and connections on your panels and seal any damages around the frame with a top-grade silicon sealer. If possible, locate and remove any trees, plants or other objects near your home that may block the sun from reaching your solar panels.
