Solar, EV & Low-Voltage Contractor Insurance

Where solar contractor insurance claims start

Solar contractor insurance has to answer for crews on roofs, energy stored in garages and numbers customers rely on. Most losses in this segment trace back to one of four things.

Height

Rooftop PV crews spend the day on pitched roofs, ladders and lifts. Across all of construction, falls to a lower level caused 389 of the 1,034 on-the-job deaths in 2024, per BLS data reported by OSHA. Fall protection (29 CFR 1926.501) is also the standard OSHA cites most, with construction ladders and scaffolding in its top 10 too.

Those are construction-wide figures, not solar numbers. They still explain why comp underwriters grill you about roof crews.

Stored energy

An array makes DC power whenever light hits it, and a home battery holds a charge with the main breaker off. A bad termination on either can sit quietly for months before it heats up.

Numbers customers rely on

Production estimates, string sizing and EV load calcs are advice. When the advice is wrong, the claim isn't about a broken part. It's about money the customer says they lost.

Systems that have to work unattended

Fire alarm, intrusion and access-control systems exist for the night nobody is home. When one stays silent, the claim lands on whoever installed or serviced it.

The coverage stack for solar, EV and low-voltage work

The first four are must-haves for almost every shop in this segment. The last two follow the work you sell.

General liability (must-have)

Injury and property damage to others, plus completed operations, which picks up a fire or failure months after closeout. General liability for electricians

Workers' comp (must-have)

Covers your installers and techs, priced by class code. Roof crews and wiring crews may rate very differently. Workers' comp for electricians

Installation floater (must-have for PV and storage)

Modules, inverters, racking and batteries you're installing, from delivery until the system is accepted. Installation floater coverage

Tools and equipment (must-have)

Meters, torque tools, crimpers, cable testers and fish tapes, on the truck or on the roof. Tools and equipment insurance

Professional liability (often needed)

System design, production estimates, load calcs and alarm system layouts. Professional liability (E&O)

Umbrella (often needed)

Extra limits when a commercial owner, utility program or GC asks for more than your GL and auto carry. Umbrella insurance

Roof work: check the GL endorsements and the comp class

Roof-work caveat

The standard ISO general liability form doesn't exclude roof work. The gaps come from carrier choices layered on top of it. Look for these on your endorsement schedule:

height limitations on stories, roof height, or ladder and lift height
roofing limitation endorsements that can reach rooftop work
classification limitations that cover only the operations listed on your declarations

Some carriers won't write ISO class 99080, Solar Energy Contractors, at all. One published BOP program turns away contractors working above three stories.

Here's the move: if you're an inside-wiring shop adding rooftop PV, tell us before the first install. We get the work classified and confirm no height or roofing endorsement quietly removes it.

Comp has its own split. NCCI's scopes manual sends rooftop panel installation to 5551 Roofing, ground-mounted installation to 3724, and the electrical work to 5190. On a rooftop job, payroll may be divided between roofing and 5190, and the carrier and auditor decide based on what each worker actually did.

The gap is real money. Indiana's advisory rates effective January 1, 2026 put 5551 at $4.160 per $100 of payroll and 5190 at $0.901. Carriers file their own deviations, but the spread shows why clean time records matter at audit.

California runs its own bureau and treats PV differently. Its class rules put photovoltaic panel installation in 3724(2), not roofing. Ask your carrier how it codes inverter and battery work.

PV arrays and batteries: long-tail fire risk and design errors

Specialty caveat

Every array or home battery you install creates a completed-operations exposure that runs for years. A loose MC4 connector, a conductor pinched under a module or a battery mounted against its listing could start a fire long after closeout.

The codes give you a paper trail. The residential code calls for stationary storage batteries to be listed and labeled to UL 9540. NFPA 855 is the standard for installing stationary energy storage systems. The PV wiring follows NFPA 70, the NEC, and the residential code also sets roof access pathways and setbacks.

Two insurance moves follow. Confirm your GL's products-completed operations coverage carries no solar or battery exclusion. Then keep commissioning records and each unit's listing documents in the job file.

Design is a separate exposure. String sizing, interconnection drawings and a savings estimate the customer signed on are professional advice. GL isn't built to pay for a design error, and many contractor GL policies carry ISO CG 22 79, which excludes engineering and design services while leaving your means and methods covered. Contractors professional liability is sold to trade contractors for exactly this, usually on a claims-made basis.

EV chargers: the load calc is the exposure

Example scenario

EV charger caveat

NEC Article 625 holds most of the rules for EV charging equipment, and service and feeder sizing follow the load calculation rules in Article 220. The Department of Energy notes that some homes lack the capacity for Level 2 charging, so a qualified electrician may need to add circuits or upgrade the service. Permits are often required.

A charger added without a real load calc, or a service upgrade the customer talked you out of, can overload conductors or equipment. That's a GL and completed-operations question. If you sell the load calc or a load-management design as its own service, it's an E&O question too.

Example scenario: A two-truck shop adds a 48-amp Level 2 charger to a 100-amp service in an older ranch house, using the homeowner's estimate of their electric use. That winter, the heat pump, dryer and charger run together and the service entrance conductors overheat. The homeowner's carrier pays for the damage and then looks to the shop. Whether the shop's GL responds may depend on its completed-operations wording, and whether the skipped load calc becomes a professional claim depends on how the job was sold.

Here's the move: document the load calc, photograph the panel schedule and get a signature on any declined upgrade.

Fire alarm, security and low-voltage work

Low-voltage and alarm caveat

Alarm work is rated as its own risk. On the GL side, ISO uses class 91127 for alarm installation, servicing or repair and 91130 for monitoring. For comp, alarm installers often fall under 7605, but that varies by state, and Texas and Massachusetts handle it differently.

Many standard programs avoid these classes. One carrier lists both GL alarm classes among those it won't write, and one BOP program declines contractors who install or service burglar alarms.

The exposure that surprises people is failure to alert. A claim may say the panel you installed or serviced didn't detect, sound or report. That's an errors-and-omissions claim, usually written as alarm-contractor E&O on a specialty program. Alarm contracts commonly include limitation-of-liability language, but whether a court enforces it depends on your state and the facts. Have an attorney draft or review yours.

Licensing for this work varies by state:

Florida requires a Limited Energy specialty license for most systems under 98 volts and licenses alarm contracting separately. See Florida electrician insurance.
Georgia licenses low-voltage work through its Division of Low Voltage Contractors in four classes. See Georgia electrician insurance.
Texas licenses alarm companies through DPS and fire alarm firms through the State Fire Marshal, and both set GL minimums. See Texas electrician insurance.

In other states, check your state board before you take on alarm or data work, or browse electrician insurance by state.

What owners, utilities and GCs will ask you for

Commercial PV and charger jobs usually come with an insurance exhibit. Expect additional insured status, waiver of subrogation and primary and non-contributory wording, all added by endorsement. A certificate alone doesn't create any of them.

Utility incentive programs set their own floors. In Texas, CPS Energy's solar program manual calls for $1,000,000 per occurrence, and Austin Energy's contractor handbook asks for $500,000 of GL, workers' comp and $500,000 of auto. Illinois requires distributed generation installers to be certified by the Illinois Commerce Commission.

Then there's the gear before commissioning. Modules, inverters, racking and batteries delivered to a site are your materials until the job is accepted, and a tools policy isn't built for them. Ask how your installation floater handles theft from the site and storage at your yard. A pallet of batteries or a commercial inverter may need its own limit.

Growing a solar, EV or low-voltage shop

Each new line of work is a coverage event, not just a sales win. Call us before these milestones, not after:

Your first rooftop array. Classification, height endorsements and the 5551 payroll split.
Your first ground mount. Different comp class, and often a different site-theft picture.
Your first battery install. Completed-operations wording, listing records and floater limits.
Your first monitoring contract. Monitoring is its own GL class and usually needs alarm E&O.
Your first design-build job. E&O is claims-made, so keep the retroactive date unbroken when you renew or switch carriers.

As commercial work grows, contract limits often climb past $1M per occurrence and $2M aggregate. An umbrella is usually how shops reach them without rebuilding every policy.

Frequently asked questions

Do solar installers need different insurance than regular electricians?

The core policies are the same, but the setup isn't. Your GL has to be classified for solar with no height or roofing endorsement that removes rooftop work, and your comp payroll may split between roofing and electrical classes. Battery installs and system design add completed-operations and E&O questions.

What workers' comp class code is solar panel installation?

In most NCCI states, rooftop panel installation is 5551 Roofing, ground-mounted installation is 3724 and the electrical work stays in 5190. California treats PV differently, and your carrier assigns the final codes.

Does general liability cover an EV charger install that causes a fire?

It may, under the completed-operations part of the policy, depending on your wording and exclusions. If the claim says your load calc or design was wrong, that part may be an E&O question instead.

Do low-voltage contractors need professional liability?

If you install, service or monitor fire alarm, security or access-control systems, alarm-contractor E&O is worth a hard look. A failure-to-alert claim is about the system not working, which general liability isn't designed to handle.

Will my tools policy cover solar panels stolen from a jobsite?

Usually not. Panels, inverters and batteries you're installing are materials, not tools, so they belong on an installation floater. Ask how the floater handles theft from the site and off-site storage.
