Welcome! If you’ve ever asked yourself “Do solar panels really need to be cleaned?”—you’re definitely not alone. After more than 30 years in the solar and home maintenance industry, we’ve found this is one of the most common questions homeowners have.
You invested in solar to save on energy bills 💰 and help the planet —so keeping those panels in top shape just makes sense. In this guide, I’ll break down whether solar panel cleaning is worth it, how often to do it , and why professional help might be your smartest move .
Why Should I Care If My Solar Panels Are Dirty?
It might not seem like a big deal, but dust, pollen, bird droppings, and leaves 🍂 can all accumulate on your panels. Even a small amount of debris can prevent sunlight from reaching the cells that produce energy.
Less light = less power —which means higher bills and less return on your investment 📉.
How Dirt Affects My Solar Panel Efficiency
When dirt builds up, it creates a barrier that blocks sunlight. This decreases the panels’ ability to convert solar energy into usable electricity.
How Often Should I Clean My Solar Panels?
This depends on your environment. In Bonita Springs, FL , you should consider cleaning every 6 to 12 months.
Live near the beach, in a wooded area , or where there’s lots of pollen? You may need to clean more frequently.
What’s the Best Way to Clean Solar Panels?
Gentle cleaning works best:
✅ Soft brushes
✅ Squeegees
✅ Purified water
🚫 Avoid harsh soaps or abrasive sponges—they can damage the surface and reduce efficiency.
Tips for DIY Cleaning
✅ Use a garden hose with a spray nozzle 🚿 ✅ Avoid cold water on hot panels (this could crack them!) ✅ Never step directly on the panels
Can I Clean My Roof Solar Panels Myself?
Technically, yes. But climbing onto a roof with a water hose and tools isn’t just risky —it can be downright dangerous.
Plus, you might void your warranty or cause damage if you’re not careful.
What Happens If I Never Clean My Panels?
Ignoring your panels can lead to a consistent drop in energy production ⚠️. Over time, this not only increases your energy bill but also reduces the overall return on your investment .
You could also shorten the life of the panels if corrosion from debris sets in.
The Cost of Not Cleaning Solar Panels
Skipping cleanings may seem like a way to save money, but it actually costs you in the long run.
Consider this: a 15–25% drop in performance can translate to hundreds of dollars a year in lost savings.
