How to Clean Solar Panels

Congrats on your new solar system! To make sure you get the most out of it, regular maintenance is key—especially keeping those panels clean. A couple of cleanings a year will ensure maximum energy production and keep everything looking great. Here’s a few tips on how to clean your solar panels safely and effectively!

Why Clean Your Solar Panels?

• Boost Efficiency: Dust, pollen, and debris can block sunlight, lowering your system's output. Clean panels = more power!
• Extend Lifespan: Regular cleaning helps maintain the quality of your panels, which can last decades.
• Save Money: A clean system generates more energy, which means lower electricity bills over time.

When to Clean

• End of Spring (Last Week of May): After a season of pollen and dust buildup, give your panels a good cleaning to refresh them for the summer sun. It's also important to clean your panels if you've recently had wildfire ash, or construction dust land on your panels.
• Beginning of Fall (First Week of September): A post-summer cleanup will remove dirt and grime from the dry months, keeping your panels in top shape as cooler weather rolls in.

The Best Time of Day to Clean

• Early Morning: This is your golden window! The panels are cool, and morning dew can help loosen dirt, making the job easier.
• Avoid the Heat: Midday heat can cause water to evaporate too fast, leaving streaks and possibly damaging the panels. Plus, it's just harder to work in the sun!

How to Clean Your Solar Panels

1. Water Only: A hose with clean water is all you need. If you're in a hard-water area, try using distilled water to avoid streaks or mineral deposits.
2. Use a Soft Brush: Gently scrub your panels with a soft-bristled brush. Nylon or polyester brushes work great—nothing too rough and avoid metal bristles as they may scratch your panels.
3. Tough Spots? Give Us a Call: If you notice stubborn stains or water spots, it’s best to call the pros for deeper cleaning.

What to Avoid

• No Solvents or Harsh Chemicals: Stick to just water. Chemicals can harm the protective coatings on your panels.
• No Pressure Washing: High pressure can crack the glass or damage seals.
• No Walking on Panels: Solar panels aren't made to support weight, so walking on them can cause cracks or internal damage.
