The Leak or Fire Can Surface Years After the Crew Leaves.
Protecting solar contractors, crews, and the systems they install
Solar installers sit at the intersection of three trades — structural mounting, roofing and waterproofing, and electrical tie-in — while working at height on roofs and handling high-value equipment meant to last 25 years. That combination shapes the risk: a solar contractor is rarely fully any one trade, and its biggest exposures often surface long after the job, when a roof penetration leaks or an electrical fault ignites. A solar business needs coverage built around the long completed-operations tail, rooftop safety, and the equipment and design exposures the trade carries. This is a corner of contractor insurance built for how solar installers actually get sued.
Properly structured coverage protects the business, its crews, and the systems it installs.
The Solar Installer's Signature Exposures
The defining exposure is the long completed-operations tail combined with roof-penetration water damage and rooftop height. Unlike most trades, a solar installer's biggest claims surface years after the crew leaves — a penetration or flashing sealed imperfectly develops a slow leak that rots decking and damages the interior two to four years later, or an electrical tie-in fault causes a fire long after installation. Because the system is warrantied to run about 25 years, that liability tail is unusually long. Rooftop falls are the dominant worker-safety hazard, electrical fire is a high-severity property loss, high-value panels and inverters are exposed in transit and before installation, and design-build installers who promise production face professional-liability exposure when an array underperforms.
Key Risks in Solar Installer Operations
Solar installers face exposure related to:
Roof-penetration leaks that surface years after installation
Electrical tie-in faults causing a fire long after the job
Rooftop falls and height injuries to crews
Panels and inverters damaged in transit or stolen before installation
Production shortfalls on design-build systems that promised output
Voided roof warranties from improper penetration
A completed-operations claim arriving many years after the work
The long completed-operations tail and rooftop exposure are what most define the installer.
Core Coverages for Solar Installers
A properly built solar program typically includes:
General Liability with Completed Operations — Covers third-party injury and property damage during and after the job — but the policy must be written to answer roof-membrane damage and post-installation leaks, which off-the-shelf general liability may exclude.
Workers' Compensation — Provides legally required coverage for rooftop falls, electrical injury, and heat, and is indispensable given height hazards.
Installation Floater — Covers the panels, inverters, and racking the contractor supplies in transit, in storage, and on site until permanently installed and accepted.
Contractor's Tools & Equipment — Covers owned tools and equipment separately from the installed materials.
Commercial Auto — Covers trucks hauling crews, panels, and racking between jobs.
Professional Liability / E&O — Responds to design and production-guarantee claims for design-build installers, and is typically claims-made, so the long tail must be maintained.
Umbrella / Excess Liability — Adds higher limits above general liability and auto for a severe fire or fall claim.
Solar Property / Builders Risk — Covers larger arrays and equipment breakdown on bigger projects.
What's Commonly Overlooked
Solar programs are most often weakened by:
Generic general liability that excludes damage to the roof being worked on
No installation floater, leaving panels and inverters uncovered before acceptance
Design-build firms with production guarantees and no professional liability
Completed-operations limits too thin for a 25-year exposure
Subcontractor risk not managed with certificates and additional-insured status
The gaps that hurt most are excluded roof-damage coverage and a missing installation floater and E&O.
Real-World Claim Examples
A poorly sealed flashing lets water intrude two years later, rotting decking and interior finishes
A crew member without fall arrest slips off a pitched roof
A defective tie-in overheats and causes a house fire months after installation
Panels are stolen from the job site or damaged in transit before installation
A commercial array underperforms projections and the owner sues for lost production value
Any one of these can be significant, and the delayed leak and fire claims carry the longest tail.
Regulatory & Licensing Context
Solar licensing is trade-split and state-specific — California's model allows a dedicated solar (C-46), electrical (C-10), or general building contractor to install systems, with roofing scope governed separately, and the electrical tie-in generally requires certified electricians. Building, electrical, and utility-interconnection permits and inspections are standard, and unpermitted work creates both regulatory and coverage exposure. OSHA fall protection requires protection for work six feet or more above a lower level, and OSHA specifically flags solar installers' roof, ladder, and scaffold hazards, while the electrical code and interconnection standards govern the tie-in.
Why Proper Placement Matters
Underwriters weigh the percentage of work at height and roof pitch, the residential-versus-commercial mix, whether the installer self-performs or subs the electrical, the crew's fall-protection and safety program, revenue and payroll by class code, average system value and inventory, and whether the firm makes production guarantees. Rooftop height, electrical fire, and the long completed-operations tail make solar a higher-hazard construction class, so many risks — especially larger commercial or heavy-height work — place in the excess-and-surplus market, where coverage adequacy on roof-damage and completed-operations wording matters more than price.
Our Approach
At Cory Washington & Co., we insure solar installers around the tail that defines the trade — confirming general liability actually answers roof-damage and post-installation leaks rather than excluding them, adding an installation floater for panels before acceptance, and maintaining design and production E&O with the tail coverage the 25-year horizon demands. We coordinate workers' compensation, auto, and umbrella and keep subcontractor risk transfer tight. We also insure related trades, including electricians, roofers, and general contractors.
A leak or fire that surfaces years later makes solar a distinct risk — we build the coverage to follow the work down the road.

How much does solar installer insurance cost?
It depends on your exposure. Solar installer insurance is priced on factors like your industry, size, prior claims, and the limits and deductibles you select — so two businesses rarely pay the same. We shop your account across competing carriers and present the trade-offs in plain English.
Who needs solar installer insurance?
Whether solar installer insurance is strictly required depends on your state, your contracts, and your lenders or clients. Even where it is not mandatory, going without it can leave serious financial gaps. We assess your exposure and any contractual requirements, then structure coverage that meets both.
What if another agency has already declined or non-renewed my coverage?
Difficult, specialty, and previously-declined placements are a core part of our work. We access excess & surplus (E&S) and specialty markets that many generalist agencies cannot, and we explain the trade-offs clearly so you can decide with confidence.
