The Hidden Cost of Dirty Panels

Your Panels Are Losing Power Right Now

Solar is a long-term investment — dirt quietly eats the return.

1

Dust & pollen build a film

San Diego's dry season coats panels in a fine film that blocks light and can cut output 10–15% before you'd ever notice.

2

Bird droppings create hot spots

Spot soiling forces panels to work around blocked cells, dropping production and creating heat that shortens their life.

3

Lost output compounds for years

A few percent lost every month adds up across a 25-year system — cleaning is one of the highest-ROI things you can do for solar.

Why It Pays

Cleaning Solar Pays for Itself in Production

Most homeowners never see the slow decline — the panels look fine from the ground while production quietly slips. We measure output before and after, so the difference isn't a sales pitch, it's a number on your report. With San Diego's long dry season and coastal dust, a clean twice a year typically returns far more in restored production than it costs. That's the whole reason we started: solar you already paid for should actually produce.

Gerald Tanaka
I watched our production numbers climb the same day Marsh & Okoye cleaned the panels — nearly 20% back. Dust and bird mess had been quietly costing us for a year. Should have done it sooner.
Melissa Ackerman
They clean the panels on our warehouse roof twice a year and the ROI is obvious in the monthly production report. Professional, safe on the roof, and they document the before-and-after output.
Dev Patel
Used deionized water so there's no spotting, and they were careful not to scratch anything or void the warranty. Explained exactly how dirt was hurting output. Genuinely knowledgeable.

Good to Know

Solar Cleaning Questions, Answered

Does cleaning solar panels really make a difference?

Yes — measurably. In dry, dusty San Diego, soiling commonly cuts output 15–25%, and bird droppings can be worse. We take before-and-after production readings so the gain is a real number, not a claim.

Will cleaning scratch my panels or void the warranty?

No. We use deionized water with soft, no-scratch tools and low pressure — the method panel manufacturers recommend. It protects the anti-reflective coating and keeps your warranty intact.

Why deionized water instead of soap?

Deionized (pure) water lifts dirt and dries with zero mineral spotting or residue — no detergents to leave a film that attracts more dirt. It's the cleanest, streak-free way to finish glass.

How often should solar panels be cleaned?

Most San Diego systems benefit from cleaning twice a year — more if you're near the coast, under trees, or dealing with birds. We'll recommend a cadence based on your site and put you on a plan if you want.

What areas do you serve?

We cover San Diego County, including La Jolla, Carmel Valley, Point Loma, Chula Vista, Escondido, and Poway. Not sure if you're in range? Just ask.
