Two crews can share the same electrician, the same truck, and the same torque wrench, and still need two different insurance files. That is the first thing to understand about solar contractor insurance. It is the program built for crews who install photovoltaic systems on property they do not own: rooftop arrays, carport canopies, ground mounts, and the racking, inverters, and penetrations that come with them. It sits next to electrical contractor insurance, which covers the full electrical trade, but it is its own conversation. It is not coverage for a homeowner who already has panels, and it is not an EV charger install. We wrote this guide for the installer whose name is on the array invoice.
We are Western Pacific Insurance, an independent agency in Henderson, Nevada, licensed in Nevada, California, Arizona, and Utah. If you want the baseline every trade shares before you get into the solar-specific parts, start with contractor insurance explained. Then come back here.
Who This Guide Is For (and Who It Is Not)
If you are a licensed crew setting modules, racking, and inverters on someone else’s roof or lot, this is your page. Residential rooftop work belongs here. So does a commercial roof mount, a carport canopy, and most ground-mount packages. The test is simple: does the invoice say solar or PV? If it does, you are in the right place.
A few neighbors of this trade have their own guides, and it is worth knowing where the lines fall:
- A service-panel upgrade with no array on the ticket is ordinary electrical work. That belongs on the electrical contractor guide.
- A wallbox or DC fast-charging pedestal is an EV charging contractor insurance question, not a solar one.
- If you run the whole site and hire the other trades, you need the general contractor insurance guide first.
- If you are a homeowner with panels on your own roof, your question is a homeowners question. We cover it on the pools, trampolines, and solar guide and the state pages linked from it.
Everything below stays with the installer.
The Five Policies Most Solar Installers Run On
Most installer operations are built on five core policies, and it helps to think of them as answering five different questions.
General liability answers: what happens when our work hurts someone else or damages their property? A homeowner slips at a temporary roof edge. A drill finds a post-tension cable. A staging cart scuffs a car in the driveway. GL is the base of the stack and the policy every certificate request starts with.
Workers compensation answers: what happens when one of our own people gets hurt? Solar work means heights, heat, and live conductors. Burns, shocks, falls, and lifting injuries are all workers comp claims, and in every state we serve, comp is mandatory once you have employees.
Commercial auto answers: what happens on the road? The vans and flatbeds hauling modules between the shop and the roof need a commercial auto policy, and it should include hired and non-owned coverage for the day an employee grabs parts in a personal car.
Inland marine, usually written as a tools and equipment floater, answers: what happens to our gear when it is not at the shop? Meters, torque tools, and spare modules travel. This is the policy that follows them.
An installation floater answers: what happens to the array itself between the warehouse and the owner’s acceptance? Modules damaged in transit or on a half-finished roof are an installation floater claim, not a GL claim.
A business owners policy can bundle GL with property coverage for the shop, which is often the right move for a smaller operation. As the book grows, two more lines earn a look. A commercial umbrella adds limits above GL and auto, and builders and property managers increasingly want that extra limit before a crew touches their roof. Professional liability responds when the complaint is about the design of the work rather than physical damage from it: a layout or load calculation that missed the structure, for example. GL treats that as a professional dispute and steps aside. If you want the technical background underwriters lean on once a book is mostly PV, the Department of Energy’s Solar Energy Technologies Office photovoltaics pages are the reference.
Which Policy Pays Which Claim
The fastest way to understand a coverage program is to map real losses to the policy that responds. These are the claims we see most in this trade.
| The claim | The policy that responds |
|---|---|
| Homeowner or neighbor slips at a temporary roof edge during an install | General liability |
| Installer is burned, shocked, or hurt in a fall, a lift, or on a hot roof | Workers compensation |
| Meter, torque wrench, or spare modules stolen from the truck overnight | Inland marine (tools and equipment) |
| Modules or inverter damaged in transit before the owner accepts the job | Installation floater |
| Truck hits a parked car between rooftops | Commercial auto |
| Fire or water intrusion traced to the array months after you leave | Completed operations on the GL policy, if the damage is to other property |
| The modules you just set fail and the owner wants a redo | Often excluded as your own work or property in your care |
| Owner says the layout or load calculation missed the structure | Professional liability, or your own pocket |
| Spare modules burn in the shop after hours | Commercial property on the shop, not the installer GL |
Two of those rows carry an asterisk in real life, and they are the two that surprise installers most. Damage to the modules you are setting usually sits outside GL. Fire or smoke that ruins the attic or the next bay is a different claim and usually is covered. We walk through that split below.
Electrician vs. Solar Contractor: Same License Family, Different Insurance File
In all four of our states, PV installation lives on a solar or electrical license, and plenty of solar shops hold an electrical card. That does not make every electrical insurance file a solar file. Electrical contractor insurance is the full trade stack: service, lighting, panels, commercial wiring. Solar contractor insurance is the installer GL file for photovoltaic work specifically, including racking, roof penetrations, and completed operations on the array. EV charger work is a third invoice again.
Here is the practical problem. If your policy was written on a lighting-and-receptacle classification and you start bidding rooftop arrays, the rating may never have priced the modules, the heights, or the penetrations. The wrong class is a rating problem, not a magic void that erases coverage, but it is exactly the kind of thing that turns a routine claim into an argument. Tell your agent what you actually bid.
If your book is broader than solar, the state electrical guides are the better starting point: Nevada, California, Arizona, and Utah.
Panels on a House You Own Are a Homeowners Question
We get this call every week, so it deserves its own section. If you own the house and the panels, the policy that matters is your homeowners policy, not installer GL. Tell your agent the panels are there. Ask how the dwelling limit treats the array and how a claim would split between the roof and the modules. That is an HO-3 conversation, and it lives on pools, trampolines, and solar and the matching state pages for Nevada, California, Arizona, and Utah.
Completed Operations and the Array Itself: Where GL Actually Draws the Line
The leak that shows up in October from a July install is a completed operations question. A standard GL policy is built to respond to injury or damage that occurs during the policy period, including damage that surfaces after you have packed up and left. But some inexpensive installer policies restrict that grant, and the restriction is easy to miss when you are comparing premiums. Before you bind, ask two questions: where does completed operations live on this policy, and is its aggregate shared with everything else or does it stand on its own?
Now the part competitors tend to skip. GL covers property damage, yes, but it typically excludes damage to the particular part of the property you are working on, and it excludes property in your care, custody, or control. The modules you are setting sit squarely in that gap. A loose clamp that needs a callback is usually a job cost you eat. A fire that ruins the attic is much more likely to be a covered property damage claim. That is the split that catches people, and it is why we tell every installer the same two things: photograph the roof before you start, and write the invoice so it matches the class on the policy.
Modules sitting in the shop or on a truck are a property story, not a liability story. Theft of staged inventory is inland marine or the installation floater. Confirm who is buying that coverage before the first pallet leaves the warehouse.
Equipment Breakdown, the Shop, and the Truck
Three side conversations come up often enough that they belong here, even though each has its own page.
Equipment breakdown. Sudden mechanical or electrical failure of an inverter or transformer years after the owner accepted the system is not an installer GL claim. It is usually a separate equipment breakdown form on the owner’s policy. Our equipment breakdown coverage guide covers it. We mention it so nobody expects the installer GL to rebuild a failed inverter down the road.
The shop. Spare modules, inverters, racking, and a bay full of waiting gear do not ride on GL, and inland marine will not replace inventory that never left the building. A business owners policy or a standalone commercial property form covers the premises, the stock, and the tools that stay put. Heat damage in a closed Henderson warehouse and a winter leak in a Utah County bay are both shop claims. Name the shop on the application so the inventory is actually insured.
The truck. The flatbed hauling modules is not the homeowner’s sedan, and a personal auto policy is a weak home for business use. Installer commercial auto covers the vans and flatbeds, plus hired and non-owned use. Start on our business auto insurance page; Henderson crews can go straight to Henderson commercial auto insurance. Keep the truck and the client’s home on separate applications so the class stays honest.
Licensing in Nevada, California, Arizona, and Utah
None of our four states has a generic “green energy” license. Each puts PV installation on a solar or electrical classification, and some split module work from NEC wiring. Here is the short version. Confirm the details with the board before you bid, because these rules move.
| State | Installer license | Watch the split | Bond and insurance rules |
|---|---|---|---|
| Nevada | C-2g Photovoltaics; full C-2 Electrical when work goes past the service panel | C-2g covers cells, batteries, and inverters that convert solar to electricity. It does not cover wiring beyond the service panel or utility-scale generation for sale. | Contractor bond from $1,000 to $500,000; every license carries a monetary limit; workers comp required for employees; the board does not require general liability. |
| California | C-46 Solar; C-10 Electrical also names PV | C-46 covers thermal and PV. In 2024 CSLB adopted a rule restricting C-46 battery work to 80 kWh and reserving larger or add-on storage for the C-10; a court blocked enforcement, and a February 2026 settlement is set to let C-46 holders install, add, and maintain batteries up to 80 kWh on systems they installed. CSLB still has to formally adopt the revised rule, so check its current position before bidding storage. | $25,000 contractor bond; sole proprietors on specialty cards generally have no GL mandate; an LLC needs at least $1 million aggregate with five or fewer people on the license; workers comp once you have help; universal workers comp for all contractors on January 1, 2028. |
| Arizona | R-11, C-11, or CR-11 Electrical for the PV electrical scope; the Registrar also treats solar installation as its own regulated scope | C-78 is solar plumbing (liquid systems only), not a PV array. Plumbing and HVAC cards that say “including solar” are not the PV electrical file either. | Bonds scale with class and volume; a license is required at $1,000 or whenever a permit is needed; the Registrar does not require general liability; workers comp at one employee. |
| Utah | S202 Solar Photovoltaic; E200 General Electrical includes S202 as a subclass under the Division’s classification rule | S202 covers modules and related components. It excludes NEC wiring, which may require hiring an E200 or E201. | General liability is required to hold a license, and DOPL raised the floor in April 2026 to $1 million per occurrence with a multi-million aggregate (confirm the current aggregate figure with DOPL); workers comp or a Labor Commission waiver. |
Read the labels literally. A Nevada C-2g is not a pass beyond the service panel. California C-46 is not a general contractor card. Arizona C-78 is liquid solar plumbing, not modules on a roof. Utah S202 does not automatically cover every wiring method on the job. Two more details trip people up: California raised its no-license threshold from $500 to $1,000 in January 2025, and a lot of pages still print the old number. And every Nevada license carries a monetary limit that caps what you can contract at one site or subdivision for one client; you can apply to the board for a one-project increase. Tell your agent which card you hold and which invoice you actually bid.
What General Contractors and Site Owners Will Ask For
A certificate of insurance is evidence of coverage. It is not coverage. That distinction matters because most general contractors, builders, and site owners have a standard ask, and the certificate has to be backed by endorsements that actually exist on the policy.
The typical floor is $1 million per occurrence and $2 million aggregate. On top of that, expect to be asked to name the GC or owner as additional insured, to provide a waiver of subrogation, and to carry primary and noncontributory wording. Ongoing operations usually run on CG 20 10, completed operations on CG 20 37, and many jobs also want CG 25 03, the per-project aggregate. A certificate that promises wording the policy does not have is a problem waiting for a claim to expose it. We read the contract language and place the endorsements the job actually requires.

What Solar Contractor Insurance Costs
We are not going to give you a monthly teaser, because any number we printed here would be wrong for your operation. Price follows classification, deductible, and payroll. A solo rooftop crew prices very differently from a shop setting commercial canopies across a warehouse roof. Height work, a helper on payroll, and a multi-site commercial book all move the class.
What we can tell you is where the bill actually comes from. The GL number by itself is rarely the surprise. The lines around it are: tools and equipment, commercial auto, the shop, and workers compensation. And a small callback usually sits inside your deductible anyway, so the insurance question is never really the size of one array. It is the class and the residential-versus-commercial split. Request a quote and we will price the work you actually do.
Seven Questions to Ask Before You Bind
Run through these with your agent before the first certificate goes out.
- What class did the carrier assign: residential rooftop, commercial, ground-mount, or a mix?
- If you penetrate roofs or set carport canopies, does the file show that exposure?
- What happens to coverage when a solar job adds a service upgrade, battery storage, or an EV charger tie-in?
- Does completed operations stay on after you leave the roof, and is its aggregate separate?
- How does the policy treat damage to the modules you just set?
- Are meters, torque tools, and spare modules scheduled on inland marine, and is there an installation floater for gear in transit?
- Can the carrier issue the additional insured wording that builders and general contractors actually ask for?
“I Only Do Residential Rooftops. Why Carry All of This?”
We hear this constantly, and it deserves a straight answer. The risk on a single tract home feels tiny. The exposure math disagrees. One trip at a temporary edge or one helper fall is enough to produce a real claim, and residential roofs are where most of those falls happen.
There is also a commercial reason. In this trade, insurance is a sales tool. Builders, HOAs, and plenty of homeowners require a certificate before you start, and the crew that can produce one in an hour wins the job the crew that cannot loses. In Utah, general liability is required just to hold a contractor license. In California, a C-46 or C-10 needs workers comp the moment you hire help. Solo operators usually need less coverage than a ten-person crew. They do not need none.
Frequently Asked Questions
Do I need workers compensation if I work alone?
Nevada, Arizona, and Utah require it once you have employees, and Utah wants a Labor Commission waiver on file when you do not. A solo California specialty contractor can often still file an exemption until January 1, 2028, unless the qualifier is an RME. Check your class against the board’s current mandatory list before assuming an exemption applies.
Does general liability cover the modules I just set?
Usually not for damage to those modules. GL typically excludes the part of the property you are working on. Fire that ruins the attic is a different claim and is more likely covered. The redo of your own install is usually a job cost.
Does an electrical license automatically cover solar installs?
The license family is often electrical or solar. The insurance class still has to match the invoice. A lighting-and-receptacle file may never have priced rooftop PV. Bid the array when the application names the array. The wrong class is a rating problem, not a void, but it is a problem.
Is a homeowners policy enough for the installer?
No. Homeowners policies exclude business activity, so paid work on someone else’s roof has no home there. The truck between rooftops falls outside personal auto once the carrier sees business use. Coverage for panels a homeowner already owns is a separate conversation.
Can I get coverage with a prior claim?
Almost always, though the market may shift. We can move a risk between standard carriers and specialty markets until the fit and the price both work.
How is this different from electrical contractor insurance?
Electrical contractor insurance covers the full trade: service, lighting, panels, and commercial wiring. Solar contractor insurance is the installer GL file for photovoltaic work, including racking, roof penetrations, the shop, and the truck. Many operations need both conversations on one program. If your book is broader than solar, start with the electrical guide.
