Conejo Valley Power Washing
Solar panels are a smart investment—but like anything that lives outside 24/7, they don’t stay spotless forever. Dust, pollen, bird droppings, ash, and general grime can build up over time, especially in Southern California. The result? Your panels may not perform as efficiently as they should.
At Conejo Valley Power Washing, we help homeowners protect their investment with safe, effective solar panel cleaning that keeps systems looking great and working their best.
Dirty Panels Can Mean Lower Performance
Solar panels are designed to absorb sunlight. When a layer of grime blocks that sunlight, your system has to work harder to produce the same output.
Even if the difference looks minor from the ground, buildup can create “hot spots” and uneven light exposure across the panel surface. That can reduce overall efficiency—especially if shading or debris hits certain areas more than others.
Rain Isn’t a Replacement for Cleaning
A common misconception is that rain “washes panels off.” In reality, rain often just moves dust around and can leave behind mineral spots—especially if grime is sticky (pollen, pollution residue, bird droppings).
If you’ve ever looked closely at a car after a rainstorm, you know the story: clean-ish, but definitely not clean.
Big Reasons Solar Panel Cleaning Is Worth It
1) Helps You Get the Most From Your Investment
Your solar system is meant to offset power costs. Keeping panels clear helps maximize the energy you’re paying for—especially during peak sun months when production matters most.
2) Keeps Panels Looking Clean and Well-Maintained
Curb appeal isn’t just landscaping—your roofline matters too. Clean panels look sharp, and a well-maintained system signals that the home is cared for.
3) Removes Bird Droppings and Stubborn Debris Safely
Bird droppings are one of the biggest culprits for reduced production because they don’t rinse away easily and can block a panel section completely. Cleaning removes those problem spots without harsh chemicals or risky tools.
4) Prevents Long-Term Buildup
The longer grime sits, the harder it can be to remove. Routine cleaning prevents layers from stacking up season after season.
How Often Should Solar Panels Be Cleaned?
Most homeowners do well with 1–2 cleanings per year, but it depends on your environment. You may benefit from more frequent cleaning if you have:
lots of trees and pollen
birds nesting nearby
nearby construction dust
wildfire ash in the area
long dry stretches with little rain
A simple check from the ground (or a quick look at production changes) can help you decide when it’s time.
Why Professional Cleaning Matters
Solar panels aren’t the place for guesswork. DIY cleaning can lead to:
scratches from improper brushes or debris
damage from high pressure used too close
cracked glass from stepping in the wrong spots
voided warranties if harsh methods are used
Conejo Valley Power Washing uses safe techniques designed for exterior surfaces—so your panels get cleaned without unnecessary risk.
A Cleaner System = A Smarter Solar Setup
If you’re investing in solar to reduce your monthly bill, it makes sense to keep the system working efficiently. Cleaning is a simple, affordable maintenance step that can help your panels stay clear, perform better, and look great.
