The Care and Feeding of Your Solar Power System

Now that spring is in the air, the weather is warming, and the sun is getting ready for its busy season, let’s talk about the best ways to make sure your solar system is always in great working order.

Most solar systems are installed on rooftops, out of sight. And because they have no moving parts that grind, squeak, and attract attention to themselves, it’s easy to forget they’re even up there. But in order to keep enjoying the tremendous energy and cost savings you’re getting from solar, your system needs a semi-annual cleaning―especially if you are located in an area that is particularly dry and dusty.

1. Safety First - The first thing to be aware of when cleaning your solar panels is always safety. Make sure any ladder you are using to access rooftop panels is stable, and work with a partner if you can. If you’re uncomfortable with heights, definitely consider hiring a professional service to perform regular cleanings.

2. Hope Floats, But Glass Cracks - Remember to avoid walking or standing on the panels while cleaning them. Although the tempered glass surface of the modules is extremely strong, the panels will break if you walk on them, and must be replaced if damaged.

3. Don’t Get Sappy - For average dust accumulations, you can simply hose the modules off. Also check for accumulations of tree sap or bird droppings, and clean them off with a sponge or squeegee using a mild dish soap and water solution.

4. Branch Out (and Off)! - Also make sure to clean leaves, branches, and other debris off the top of the modules, and remove any material that may have become lodged under the modules, as it could reduce cooling airflow, or cause water to back up in a severe rainstorm.

Just as you do for your home and your car, it’s important to keep your solar power system well maintained in order to get the most value from your investment. A quick cleaning a couple of times a year will keep your system cranking out that solar goodness for years to come!
