Solar Panel Cleaning in Napa Valley & Bay Area

At Napa Valley Steaming, we specialize in professional solar panel cleaning to keep your panels performing at their best. Dust, pollen, bird droppings, and other debris can significantly reduce solar efficiency—sometimes by as much as 20–30%. Our eco-friendly cleaning service restores your panels’ output while protecting their surface and warranty.
 

Why Solar Panel Cleaning Matters

• Boost Efficiency – Clean panels absorb more sunlight, increasing energy production.
• Extend Lifespan – Removing debris prevents long-term surface damage.
• Protect Warranty – Many manufacturers require regular maintenance to keep warranties valid.
• Improve ROI – Maximize the return on your solar investment with routine cleanings.
 

Our Cleaning Process

We use pure deionized (DI) water and soft-bristle water-fed poles to gently wash away dirt and buildup without scratching or leaving mineral spots. No harsh chemicals are used, ensuring your panels are safe and environmentally friendly.
 

When to Schedule Solar Panel Cleaning

• At least once or twice a year (spring and fall are ideal)
• After wildfires or heavy dust storms
• When you notice reduced energy output
• Before an energy audit or inspection
