Frequently asked questions

Solar panel cleaning with SevenfoldFL starts at $199 for a single-story home with up to 16 panels. The price goes up with panel count and roof height, and three-story homes, complex roofs and commercial arrays are quoted individually. The online calculator shows your exact price in about a minute.

We don't guarantee an increase, but most customers see one. Dirty panels can lose a meaningful share of their output. In Florida, pollen, salt film, mineral deposits from afternoon storms and bird droppings build a layer that blocks sunlight and quietly drives production down. Check your monitoring app the week before and the week after a cleaning to see your own numbers. Many manufacturers also recommend regular cleaning as part of normal maintenance, so routine service helps protect your warranty.

Most residential cleanings take around two hours, depending on panel count and how much buildup there is. Adding window cleaning to the same visit usually adds one to two hours.

No. As long as we can reach the panels or windows and have any gate codes, you don't need to be home. We clean, photograph the results, complete your service record and follow up. Many customers are at work when we come by.

No. Doing it wrong is what causes problems: pressure washers, abrasive pads, harsh chemicals or walking on the glass. We use manufacturer-approved methods, deionized water and soft brushes, and we check each brand's cleaning guidance, so your coverage stays protected.

Both. Loose dust is the easy part. We focus on the bonded-on grime: bird droppings, hard-water spots, mineral haze, salt film and pollen film that rain won't rinse off. That layer is what damages panels over time, so it's the most important thing to remove.

Never. Walking on solar glass causes micro-cracks that grow over time and permanently reduce output. We clean with extension poles and soft brushes, so your panels never carry a person's weight.

At minimum once a year, and every six months is what we recommend for most Tampa Bay homes. Coastal arrays with salt exposure and roofs under trees may need it more often. Our why clean solar panels guide explains the reasoning.

Safety, mostly. Roof work is dangerous, and the cleaning itself is easy to get wrong: hard tap water leaves a mineral haze that bakes on in the Florida sun, pressure washers can damage the glass and seals, walking on panels causes micro-cracks, and household cleaners can harm the anti-reflective coating. More in our guide on whether you can pressure wash solar panels.

Yes. We clean exterior windows and sills for homes and businesses with the same pure-water, soft-brush approach we use on solar glass. Book windows on their own, or add them to a solar cleaning visit so both are done in one trip. See window cleaning.

For most Tampa Bay homes we suggest exterior window cleaning two to four times a year, and more often near the water where salt film builds quickly. Storefronts usually need monthly or more frequent service. Our window cleaning schedule guide breaks it down.

Our standard window service covers exterior glass and sills. If you also want interior glass or screens done, mention it when you request a quote and we'll tell you whether we can include it.

Yes. Sevenfold Care is our annual plan: two cleanings a year, six months apart, and you save $50 when you sign up on the day of your first service. It includes a service record each visit, priority scheduling and a one-year term with no auto-renewal.

You save $50 on the year, we handle the scheduling so you never have to remember when the next cleaning is due, and members get priority booking in our busy months.

Yes. We clean solar arrays and windows for offices, storefronts, warehouses, HOAs and other properties on monthly, quarterly, semi-annual or annual schedules, with a service agreement and a record of every visit. See commercial contracts.

Yes. Property managers, HOAs and business owners can request proof of our general liability coverage before we start work.

We are a specialty contractor for glass. Solar panels and windows are the work we do every day, not an add-on to a pressure-washing business. That means manufacturer-approved methods, deionized water and soft brushes on every job, a written service record after every solar visit, and a straight answer when something is outside our expertise.

Yes. Sevenfold Solar Cleaning is now SevenfoldFL: same owner, same crew, same phone number. We changed the name when window cleaning became a core service alongside solar. Reviews that mention Sevenfold Solar Cleaning are ours.

Yes. SevenfoldFL is bonded and carries general liability insurance, so you're protected during the job. Florida doesn't require a contractor's license for solar panel or window cleaning, but we treat every roof and system like our own.
