Solar Panel Cleaning & Exterior Surface Experts
Why Clean Solar Panels?
At Herces Janitorial Services, we use a deionized soft wash system to clean solar panels safely and effectively. This method is specially designed to protect delicate surfaces while restoring maximum efficiency.
Our process includes:
- Low-pressure water flow to avoid damaging the panels
- Deionized water for a spot-free, streak-free finish that won’t leave mineral deposits
- A soft-bristle brush to gently scrub away dust, pollen, bird droppings, and grime
- Eco-safe cleaning approach that aligns with manufacturer recommendations
Dirty solar panels can lose up to 20–25% of their efficiency due to dust, pollen, bird droppings, and debris.
Regular professional cleaning ensures:
- Improved energy production
- Longer lifespan of panels
- Protection of your solar investment
Best Time to Clean:
- Spring & Fall: Minimize buildup after seasonal changes
- After Windy or Fire Season: Remove ash and airborne debris
Recommended Frequency:
- Residential Panels: Every 6–12 months
- Commercial Installations: Every 3–6 months
