TL;DR
You don't need a state contractor license to clean solar panels in Florida if you're only washing them, per Florida Statute 489.103(6). You do need a local business tax receipt. The average cleaning costs $150 to $300 per visit, and a typical residential job takes under two hours. Renewing your business registration is mostly paperwork and a few fees.
Do you need a license for solar panel cleaning in Florida?
No. You don't need a state contractor's license to wash solar panels in Florida, as long as the cleaning doesn't involve any structural alteration. That's straight from Florida Statute 489.103(6) [1]. The statute exempts work "for the cleaning of the exterior of any residential or commercial building, including the roof." Use water and a brush on the panels and you're not a contractor in the eyes of the state.
You still have to register the business. File with the Florida Division of Corporations (Sunbiz) and get a local business tax receipt from your county [2][3]. Hire employees, and workers' compensation insurance is mandatory [7]. Offer repairs or touch the electrical side, and you fall back under the contractor rules and need a license from the DBPR [6].
A lot of new operators skip the business tax receipt and get fined. Don't be that person. The state's unlicensed activity enforcement is real, but for pure cleaning they're not hunting for a contractor license. They want the receipt. Start there.
How much does solar panel cleaning cost in Florida?
The average residential cleaning in Florida runs $150 to $300 per visit, according to EnergySage's 2023 pricing data [4]. That covers a typical 20 to 30 panel system. Per panel, figure $10 to $20, with higher rates for steep roofs, two-story homes, or heavy soiling [12]. Some companies charge a flat rate. Others bill by the panel or by the hour.
Prices tend to cluster around $199 for a basic DI water wash on a single-story ranch. That lines up with what many national companies charge. The real cost driver is water quality. Florida tap water is hard and full of minerals, and if you use it you'll leave spots that actually hurt panel output. Deionized (DI) water is the standard, and a portable DI tank adds roughly $30 to $50 to the job cost whether you rent or own it.
Here's what you can expect to pay, or charge, in Florida right now:
| Service | Price Range |
|---|---|
| Residential wash (DI water, one story) | $150 - $250 |
| Residential wash (two story, steep roof) | $250 - $350 |
| Per panel rate | $10 - $20 |
| Commercial flat roof (up to 100 panels) | $400 - $800 |
These numbers come from a mix of industry surveys and local company pricing pages [4][12]. They're averages, so your actual quote depends on the array size, roof pitch, and whether you have to bring in a lift. Starting out, price at the low end to build a client base, then raise rates once you're booked solid.
How long does solar panel cleaning take in Florida?
A typical residential job with 20 to 30 panels takes about 1 to 2 hours of actual cleaning time, plus travel [5]. That's for a two-person crew running a DI water-fed pole system. Working alone, add 30 minutes. The panels aren't the holdup. Roof access, ladder setup, and safety checks eat the clock.
Commercial jobs scale differently. A 100-panel flat roof can take a crew of two half a day, mostly because you're walking a huge area. Most Florida roofs are low pitch, which speeds things up. But the afternoon heat is no joke. Crews often start at 7 a.m. and finish by 10 a.m. to beat the worst of it.
Booking your own cleaning? Always ask about roof type and access. A single-story ranch with a 4/12 pitch cleans in under an hour. A two-story tile roof with a steep pitch runs 3 hours minimum. Panels caked in pollen or bird droppings? Double the time.
What insurance do you need for a solar panel cleaning business in Florida?
General liability insurance is the floor. Carry at least $1 million per occurrence, which covers property damage and bodily injury. Most residential clients ask for a certificate of insurance before they let you on their roof. If you have employees, Florida law requires workers' compensation coverage [7]. The state is strict, and fines for noncompliance run into thousands of dollars.
Add commercial auto insurance if you drive for work, and inland marine insurance for your equipment. A DI water system and pole can cost a few thousand dollars, and standard auto policies usually won't cover business gear in the truck.
One more thing. A sole proprietor with no employees can get an exemption from workers' comp, but you still file the exemption form with the state. Hire even one sub, and that exemption is gone.
How do you register your solar panel cleaning business in Florida?
Start with Sunbiz. Go to dos.myflorida.com and file your LLC or corporation. The filing fee is $125 for an LLC, and you designate a registered agent. If you're doing business under any name other than your legal name, file a fictitious name too. That's another $50 [2].
Next, head to your county tax collector and get a business tax receipt. The fee varies by county and business type, but expect $25 to $100 [3]. Some counties require a zoning review first. City businesses may need a separate city license. In Miami-Dade, plenty of operators end up carrying both a county and a city receipt.
You'll also set up sales tax collection with the Florida Department of Revenue. Even though you sell a service, many counties treat cleaning as taxable. Call the DOR and confirm your situation. They're helpful, honestly.
Then renew every year. The Sunbiz annual report is due by May 1, and it costs $138.75 [9]. The business tax receipt renewal is usually annual, with a deadline that varies by county.
Do you need a contractor's license for roof access in Florida?
No, not for cleaning alone. The same exemption in Florida Statute 489.103(6) that covers cleaning also covers getting on the roof to do it [1]. The controlling phrase is work that "does not require a building, electrical, plumbing, mechanical, roofing, or other permit." You can walk the roof, use a ladder, and run a water-fed pole without a contractor's license.
Start tightening loose panels, repairing mounting hardware, or anything that reads as construction, and you cross the line. Then you need a general contractor's license or a specialty license from the DBPR. Don't do it. Stick to cleaning water and dirt.
OSHA requires fall protection for work above 6 feet, so your crew needs harnesses and anchors. That's a safety rule, not a state license. On a commercial roof, the building owner may require a certificate of insurance naming them as additional insured. That's common.
What are the environmental regulations for solar panel cleaning in Florida?
Use only deionized water and no chemicals, and you're in the clear. Pure water runoff off a solar panel is essentially rainwater. The Florida Department of Environmental Protection doesn't regulate it as a discharge [10]. Add soap, detergent, or any cleaning agent, and the runoff becomes a pollutant. At that point you may need a National Pollutant Discharge Elimination System (NPDES) stormwater permit from the EPA [8].
Most residential cleaners sidestep this by sticking to DI water. The water itself lifts dirt and bird droppings without chemicals. Some companies use a trace of isopropyl alcohol in winter to stop freezing, but that's negligible.
Commercial jobs on large flat roofs often have drains that feed straight to the storm sewer. Use any cleaning solution there and you're inviting a visit from the DEP. The rule is simple. If you wouldn't drink it, don't let it go down the drain.
How to renew your solar panel cleaning business registration in Florida
Renewal is paperwork and a few fees. Your LLC's annual report is due every year by May 1. File it online at Sunbiz for $138.75 [9]. Miss the deadline and there's a $400 late fee, and eventually the state can dissolve your business. Set a calendar reminder.
Your county business tax receipt needs renewal too. The process varies, but most counties mail a renewal notice. The fee matches the initial one, $25 to $100. Change your business address, and you update it with both Sunbiz and the county.
Insurance renews annually as well. Keep your certificate of insurance current and send copies to any client who wants annual proof. If you have employees, keep the workers' comp policy active. The state's stop-work order for lapsed coverage can shut you down overnight.
One last item. Using a DBA? Renew it with Sunbiz every five years. It's easy to forget, and then you lose the name.
What equipment do you need for solar panel cleaning in Florida?
The core of any Florida rig is a deionized (DI) water system and a water-fed pole with a soft brush. A basic starter kit, like the one from SolarWashPath, runs about $149 and includes a DI water filter and a roof-safety harness [11]. That's enough for small residential jobs. As you grow, add a larger DI tank, a telescoping pole that reaches 30 feet, and a pure water rinse system.
You also need a ladder rated for your weight plus gear, a tool belt, and non-slip shoes. Buy a fall protection kit with a roof anchor and lanyard even if OSHA doesn't require it for residential work. It's cheap insurance.
Florida's sun is brutal, so pack sunscreen, a wide-brim hat, and plenty of water. People pass out on roofs in July. It's not worth it. Start early, work fast, and get off the roof before noon.
How to get customers for solar panel cleaning in Florida
Your best lead source is partnerships with solar installers. When a homeowner gets a new system, the installer often recommends a cleaning schedule. Be the name they hand out and you're set. Offer the installer a referral fee or a discount on their own panels.
Online, you need to rank for "solar panel cleaning Florida" and city-specific terms. A Google Business Profile is non-negotiable. Get reviews. Ask every client for one. Florida's seasonal residents are a big market. Snowbirds leave for the summer and come back to dirty panels, so market to them in April and May.
Door hangers still work in neighborhoods thick with solar. Find a new development with solar homes and blanket it. Your cost per lead is low, and once you clean one house on the street, the neighbors see you and ask for a card.
Common mistakes to avoid when starting a solar panel cleaning business in Florida
The biggest mistake is skipping the business tax receipt. The second is using tap water. Hard water spots cut panel efficiency, and once they bake on, they're a pain to remove. Use DI water from day one.
Another mistake is underestimating the physical toll. Roof work in Florida is hot, and shingles are sharp. You'll go through gloves fast. Don't clean panels in direct afternoon sun either. The glass gets hot, the water flashes off, and you're left with streaks. Clean in the morning or on cloudy days.
Don't overpromise on energy savings. Cleaning can lift output, but the gain depends on how dirty the panels were. Florida's frequent rain washes away some soiling, so the bump is often smaller than in Arizona. Be honest with customers and they'll stick with you.
How much can you earn with a solar panel cleaning business in Florida?
Do two jobs a day at $200 each and you're grossing $400 a day, roughly $8,000 a month working five days a week. After DI water, fuel, insurance, and equipment maintenance, you might net $5,000 to $6,000. That's a solid living for a one-person operation.
Add a crew and you scale. A two-person team can do three or four jobs a day, bringing in $600 to $800. The margins hold up because ongoing costs stay low. The biggest per-job expense is DI water, at roughly $0.50 to $1.00 per gallon, and you'll use 10 to 20 gallons per job.
Commercial contracts pay more and take longer. A 200-panel commercial roof might pay $1,000, but you'll need a crew and a lift. Line up a few strip malls and you've got recurring revenue.
Is solar panel cleaning worth it in Florida?
Yes, but the gains are smaller than in dry climates. Florida's rain does a decent job washing away loose dust and pollen, but it won't remove bird droppings, tree sap, or the fine film that builds up over time. The National Renewable Energy Laboratory has found that soiling can reduce annual energy production by a few percent depending on tilt and local conditions [13]. For a 10 kW system, that's real money over a year.
Run the math. Clean twice a year at $200 a pop and you spend $400. If the cleaning boosts output by 5% on a $2,000 annual bill, you save $100. Borderline. But many homeowners clean for peace of mind and to protect their investment. Running a cleaning business, that peace of mind is what you're selling, more than the kilowatt-hours.
Frequently asked questions
Do you need a license for solar panel cleaning in Florida?
No state contractor license is required for cleaning solar panels if the work does not involve any structural alteration, per Florida Statute 489.103(6). You do need to register your business with Sunbiz and obtain a local business tax receipt from your county.
How much does solar panel cleaning cost in Florida?
The average residential cleaning costs $150 to $300 per visit, according to EnergySage. Per panel rates range from $10 to $20. Prices vary with roof height, pitch, and soiling level.
How long does solar panel cleaning take in Florida?
A typical residential job with 20 to 30 panels takes 1 to 2 hours of actual cleaning time, plus travel. Larger commercial jobs can take half a day or more.
How often should you clean solar panels in Florida?
Most Florida homeowners clean once or twice a year. If you have trees overhead or notice a drop in output, you might need to clean more often. Rain helps, but it won't remove bird droppings or sap.
Can I use a pressure washer to clean solar panels?
No. Pressure washers can crack the glass or force water past the seals. Use a soft brush with deionized water and a gentle flow. The rule is simple: if it's strong enough to clean a car, it's too strong for panels.
Do I need a business license to clean solar panels in Florida?
You need a business tax receipt from your county, which is the local equivalent of a license. You'll also need to register your business entity with the Florida Division of Corporations.
What is the best time of year to clean solar panels in Florida?
Spring and fall are ideal. Avoid the midday summer heat, which can cause water to evaporate before you rinse. Morning cleanings are best, especially from June through September when roof glass gets hot fast. A March or April visit after pollen season, plus an October visit after summer storms, covers most Florida homes. Skip midday July and August unless the array is shaded.
Do I need to be bonded for solar panel cleaning in Florida?
Bonding is not required by the state, but some commercial clients or homeowners' associations might ask for it. It's a way to guarantee your work and protect against theft.
Are there any tax incentives for solar panel cleaning in Florida?
No direct tax incentives exist for cleaning. However, maintaining your panels keeps them operating at peak efficiency, which protects the value of the federal solar tax credit you may have already claimed.
What is the deionized water process for solar panel cleaning?
Deionized (DI) water has had its mineral ions removed, so it dries spot-free. You run a filtration system to produce DI water, then pump it through a water-fed pole with a brush. No chemicals needed.
How to renew my business tax receipt in Florida?
Your county tax collector mails a renewal notice each year. You can usually renew online or by mail. The fee is typically the same as the initial fee, $25 to $100. Deadlines vary by county.
What if I damage a solar panel while cleaning?
Your general liability insurance should cover property damage. Always inspect the panels before cleaning and document any existing cracks. If you cause damage, you'll file a claim and may have to pay the deductible.
