Commercial Solar Panel Cleaning in the Greater Bay Area

Module warranties set their own cleaning conditions, and following them is what protects yours. We use deionized water and soft-bristle equipment, and we do not pressure wash or use chemicals, which keeps our cleaning inside the conditions module warranties typically require. Warranty terms are set by the manufacturer, not by us.

Yes. Total Solar Cleaning runs a SolarCleano F1 robot in its 47-inch configuration on commercial carport canopies across the Greater Bay Area. The unit goes onto the canopy by lift and stays intact between rows; the lift moves the robot from row to row without dismantling it. Elevated carports are routine commercial work for us.

Deionized water dries without leaving mineral residue on the glass, and some module manufacturers set a hardness limit for cleaning water. Contra Costa Water District's 2025 published average hardness is 74 mg/L, in a range of 53 to 116. One major module manufacturer's cleaning specification requires water under 75 mg/L. Local tap water sits on that line, so we deionize rather than rely on it.

Twice a year is the honest default for most East Bay commercial arrays. Two site conditions change that. A large resident bird population leaves concentrated droppings on the glass between visits, and construction or agricultural activity nearby puts a steady dust load on it. Sites with either condition often justify more frequent service. Monthly service is easy to sell and hard to justify, and we will tell you when your site does not need it.

Yes. Total Solar Cleaning runs evenings, weekends, and overnight. For school sites that usually means over a weekend, on a non-school day, or in June or July. The work happens outside school hours, so the crew is not working around a live campus. Tell us your operating schedule and any site access requirements your district applies to contractors, and we will scope the visit around them.

Total Solar Cleaning carries $2,000,000 in general liability coverage. Our crews are safety-trained for the elevated and rooftop work commercial arrays require, and our lead technician is ISCA certified through the International Solar Cleaning Academy.

The robot makes sense from roughly 300 panels up. Below that a crew is faster, and we will say so before we quote the equipment. Our commercial work is solar carports, flat commercial roofs, ground mounts, and multi-site portfolios across the Greater Bay Area.

Every commercial job ends with before and after photographs of the array. Recurring contract accounts get the same record for each site on every visit, and one point of contact handles scheduling and reporting across the whole account.

Commercial jobs are quoted from three things: array size, access requirements, and your operating schedule. A flat per-panel rate hides more than it tells you, because a 200-panel carport over a live parking lot and a 200-panel ground mount behind a fence are different jobs. One-off pricing is the standard rate; twice-a-year service contracts run about 10% below it, and quarterly service contracts run about 20% below it. Send us those three facts and we will come back with a scope and a number.

Yes. We hold six recurring commercial accounts, and our largest covers 18 sites under one contract. Property management companies, apartment communities, office parks, and warehouse rooftops get one point of contact, one schedule, and per-site before and after reporting on every visit.
