Why It’s Important to Clean Your Solar Panels

This entry was posted in Solar Services on by .

Regular cleaning of your home’s solar panels in the Valley of the Sun, with our dust storms and long stretches of time without rain, will keep your system running efficiently and extend its lifespan. In general, we recommend cleaning panels at least every six months. Here’s what you need to know.

Why Clean Solar Panels?

Dirt is the enemy of your solar panel system. When dirt, dust, grime, and other contaminants build up on panels over time, the efficiency of your solar panels drops.

When to Clean

If you see a thick film accumulated on your solar panels, leaves or branches, palm tree debris, bird droppings, or excessive amounts of dust or pollen, it’s probably time for a panel wash.

How to Clean

Before you begin cleaning, it’s always wise to read your solar panel manufacturer’s specific recommendations on how to best clean solar panels. Some systems need to be shut down before cleaning. And there might be other unique requirements.

  • You may want to invest in a solar panel cleaning kit that contains specialized soap to use, a cleaning brush, and a squeegee. Typical home cleaning supplies like biodegradable soap can also be used, but may not thoroughly clean the panels.
  • Use your garden hose to rinse off dust, dirt, and grime built up over fall and winter months. This will easily remove loose debris, making it easier to clean your solar panels with soap. Cleaning your solar panels with cold water on a very hot day may cause streaking on the panels or possibly stress cracks. The best time to clean panels is during early morning hours when temperatures are lower.
  • Don’t assume pressure washers or abrasive detergents would be the way to clean your solar panels. Unfortunately, using a pressure washer can easily scratch the panels and damage the photovoltaic cells. High water pressure directly on the panels can also damage the seal around the panel frame, potentially allowing water to enter the panels and voiding the warranty.
  • If your rooftop panels can’t be safely and effectively cleaned from ground level without having to climb a ladder, it may be safest to contact your professional solar installer. They’ll ensure the job is done correctly, giving you peace of mind and avoiding costly damage to your solar panel system.
