PV Panels — Cleaning & Maintenance

More light in, more power out. Dust, pollen, ash, salt, and bird droppings cut production and can create hot spots. We clean solar arrays safely and leave the glass streak-free so your system delivers the energy you paid for.

Why it matters

• Restores output — many homes see a noticeable gain after cleaning
• Reduces hot-spot risk and heat stress on cells
• Helps protect module finishes and keeps warranties on track
• Keeps monitoring graphs honest by removing soiling as a variable

How we clean

• Deionized, spot-free water and soft-bristle poles for a gentle wash
• Low-pressure rinse — no pressure washers, no abrasive pads, no harsh chemicals
• Work during cool hours to avoid thermal shock to hot glass
• Check array edges, clamps, wiring, and penetrations while on site
• Optional critter guard to keep birds and debris out from under panels

When to schedule

• 1–2 times per year in most areas
• After pollen season, wildfires, dust storms, or coastal salt build-up
• If monitoring shows a slow, weather-independent production drop
• Rain helps, but it rarely removes baked-on grime
