Solar panels are built to be low-maintenance—but they’re not “no-maintenance.” Over time, dust, pollen, bird droppings, ash, and grime can build up on the surface and reduce how much sunlight reaches your panels. If you want your system performing the way it should, now is the time to get your solar panels professionally cleaned.

At Conejo Valley Power Washing, we help homeowners and property managers keep solar panels clean, clear, and operating efficiently.


1) Dirty Panels Can Reduce Performance

Even a light film of dust can block sunlight. Heavier buildup—especially in dry, windy areas—can lead to noticeable performance loss. Cleaning helps restore the panel surface so it can absorb sunlight properly.

If you’ve noticed your system producing less than normal, the issue may be as simple as buildup on the glass.


2) Wind, Pollen, and Bird Droppings Add Up Fast

Solar panels don’t stay clean on their own. Common culprits include:

  • Dust and road grime

  • Pollen and seasonal debris

  • Bird droppings and nesting activity

  • Ash and fine particles (especially after windy conditions)

  • Leaves and debris collecting near the edges

A professional cleaning clears the surface and prevents “hot spot” areas caused by uneven coverage.


3) Cleaning Helps You Protect Your Investment

Solar is a long-term investment. Keeping panels clean helps you get the most out of your system over time—especially during high-sun months when production matters most.

Regular cleanings can be part of a simple maintenance routine that keeps your system performing year after year.


4) It’s Safer (and Better) Than DIY

Climbing onto a roof is risky, and using the wrong tools can damage your panels. Professional solar panel cleaning should be done carefully:

  • No harsh chemicals

  • No abrasive brushes

  • No high pressure directly on panels

  • Proper technique to avoid scratching or damaging seals

We use safe methods designed for solar surfaces and work with roof safety in mind.


5) You’ll See the Difference

Most homeowners notice an immediate improvement in how their panels look—and many see improved production shortly after cleaning, especially if the panels were heavily soiled.

Even better: clean panels also improve curb appeal, especially on homes where panels are visible from the street.


How Often Should Solar Panels Be Cleaned?

It depends on your environment, but many properties benefit from service 1–2 times per year—and more often if you’re near:

  • construction dust

  • heavy pollen areas

  • birds nesting nearby

  • windy zones or hillside debris

  • roads with regular dust and grime

If it’s been a while, a quick inspection and cleaning is the easiest way to get back on track.
