Maximizing Your ROI: How Much Does Cleaning Actually Increase Efficiency?

You made a heroic investment in solar to lower your bills and protect the planet. But if your panels are covered in a layer of San Diego dust and salt air, you aren't getting the full "win" you paid for.

In the solar industry, we call this "Soiling Loss." While it sounds minor, the impact on your wallet is anything but.

​

The Efficiency Gap

Dust, pollen, bird droppings and salt film build up between rains and block sunlight from reaching your cells, so a dirty array quietly produces less power than it should. The longer San Diego goes without rain, the more that buildup costs you.​

​

• The Light Barrier: Dust, pollen, bird droppings, and salt film create a physical barrier. Every photon of light that is reflected or absorbed by dirt is a photon that isn't being converted into electricity for your home.

• The Temperature Factor: Darker "grime" can actually cause panels to retain more heat. Since solar panels are more efficient when they stay cool, this extra heat further degrades your energy production.

​

Restoring Your Performance

As your expert guides, our goal is to bring your system back to its "Day One" performance levels. By removing the built-on grime that rain simply can't touch, a professional cleaning lets full sunlight reach every cell again, so your panels can produce the power they were designed to make. Clean panels also run cooler, which helps them last longer, and every cleaning includes a safety inspection of your array.​

​

If your monthly solar production has been steadily declining despite sunny weather, you likely have a "soiling" problem. Cleaning is the fastest, most cost-effective way to boost your ROI without adding more panels.
