Why Use Our Solar Cleaning Calculator?
Dirty solar panels can cost you hundreds of dollars in lost power generation. Our calculator helps you estimate the cost of maintenance so you can weigh it against your energy savings. By accounting for roof height and panel count, we provide a realistic quote that reflects the safety and labor requirements of the job.
Manually Calculating Solar Panel Cleaning Costs
To estimate manually:
- Count Panels: Most residential systems have 15-30 panels.
- Base Rate: Multiply panels by $20. (Example: 20 panels x $20 = $400).
- Access Factors: Add 20% if 2-story ($480). Add 20% if steep roof ($576).
- Minimums: Most pros won't come out for less than $150, even for 5 panels.
Manual Calculation Formula:
Est. Cost = (Panel_Count × $20) × Difficulty_Multiplier + Addons
*Example: 24 Panels ($480) on steep roof (x1.2) = $576 Total.
Frequently Asked Questions
How much does solar panel cleaning cost?
Typically $15 to $25 per panel, with a minimum service charge of around $150-$200.
How often should I clean my panels?
Every 6 months to 1 year. If you live in a dusty area or near farmland, more frequent cleaning may be needed.
Can I just use a hose?
Hosing them down helps, but it leaves mineral deposits (hard water spots) that block light. Professionals use deionized water for a spot-free rinse.
Does cleaning improve efficiency?
Yes, dirty panels can lose 15-25% of their energy output. Cleaning restores this lost production.
Is bird proofing worth it?
If you have pigeons nesting under the panels, absolutely. Nests cause heat buildup and wiring damage.
Do you use soap?
Ideally no. Standard soaps leave a film. We use pure water and specialized solar-safe brushes.
Can I walk on the panels?
Never. Panels are glass and can micro-crack under weight. We use extension poles or safety harnesses to reach them.
Does rain clean the panels?
Rain clears loose dust but doesn't remove bird droppings, pollen, or smog layers. It's like waiting for rain to wash your car.
