QuoteIron › Pressure Washing price book › Clean Solar Panels
The book prices an array of up to 20 panels at 2 hours and $13 of materials: deionized water and a soft brush, no detergent, no pressure. It is a labor-and-safety price. The roof is the risk, and an insurance and fall-protection plan belongs inside the number.

What moves the price
- Access and safety. Roof pitch, height and surface decide whether you can do it at all. Do not quote a job you cannot reach safely.
- Method. Pressure and detergent can void a panel warranty or damage the coating. State your method on the quote.
- Bundle it. Solar panel cleaning pairs with gutter cleaning and roof soft-wash on the same ladder day.

How these numbers are built
QuoteIron’s price book stores structure: typical labor hours and a mid-grade parts cost for each job (book priced 2026-09). Your rates do the pricing: hours × your hourly rate, plus parts at cost with your markup, rounded up to the next $5. The low, typical and high figures use $75, $95 and $125 an hour at the book’s default 30% markup. They are formula outputs, not a survey of what your market pays, so replace them with your own rate and markup before you send anything. Prices checked October 8, 2026.
