This is the reality of insuring solar work in 2026: the exposures that actually generate claims—completed operations, workmanship-versus-weather disputes, panels in transit, energy-yield guarantees—are exactly the ones a thin, standard-market policy tends to under-cover. This guide breaks down the solar contractors we insure, the solar-specific risk profile, the coverage lines that matter most, and state-by-state considerations across California, Texas, Alaska, New Mexico, Oklahoma, Pennsylvania, North Dakota, and Nevada. It’s the first spoke off our broader alternative energy insurance guide.

The 2026 Solar Market: A Tale of Two Segments

Solar is still the story of the U.S. grid—the country surpassed 6 million cumulative installations in 2026, and solar together with storage made up the overwhelming majority of new capacity added in the first quarter. But underneath that headline, the market has split into two very different segments, and the split has real consequences for how contractors should be insured.

On one side, utility-scale solar is booming. Contracts for large projects rose roughly 15% year over year, driven heavily by technology companies locking in power to feed AI and data-center demand. Utility resource plans are loading up on solar procurement, and the fleet is on track to roughly double over the next five years.

On the other side, residential solar is contracting hard. After the Section 25D residential tax credit expired at the end of 2025 on a hard cliff—no phase-down—residential installations are forecast to fall 18–21% in 2026, and customer-acquisition costs have spiked. More than a hundred solar companies have closed or filed bankruptcy since 2023, including one of the largest residential installers in the country in early 2026. Commercial and C&I solar sits in between, with a modest near-term dip before growth resumes later in the decade.

Why does this matter to an insurance program? Because a contracting, consolidating installer market changes the risk, not just the revenue. When a company that installed thousands of systems disappears, its workmanship warranties and completed-operations obligations don’t vanish—they land on remaining contractors, O&M firms, or whoever acquires the orphaned systems. Lenders and developers know this, which is why they increasingly scrutinize contractor financial stability and demand documented completed-operations coverage and bonds. The one segment growing inside the contraction is battery storage, with attach rates near 45% and roughly 50% year-over-year growth—which pulls its own fire and commissioning exposures onto solar sites.

Types of Solar Contractors We Insure

“Solar contractor” covers a wide range of firms, and where a company sits in the value chain determines which coverage lines carry the most weight.

Residential & Commercial Installers

Rooftop and small ground-mount installers face fall and roof-penetration exposure, electrical hazards, and workmanship claims that can surface years after the job. In a tighter market, these firms also inherit warranty and service obligations from failed competitors—making completed operations and clear contract terms essential.

Utility-Scale EPC Contractors

Engineering-procurement-construction firms carry the heaviest exposure set: large civil and electrical scopes, energy-yield and performance guarantees, lender-driven limit requirements, and significant equipment values on site. Their programs typically layer professional/E&O and builder’s risk or inland marine on top of a robust GL and excess tower.

Solar Carport & Canopy Builders

Carport and canopy work blends structural steel and foundation construction with electrical and vehicle-adjacent exposure. These projects introduce elevated property-damage and third-party risk—vehicles, pedestrians, and structures beneath the array—that a pure rooftop-installer policy isn’t built to handle.

O&M and Repowering / Decommissioning Firms

Operations-and-maintenance and repowering contractors increasingly service orphaned or aging systems. Their exposure is dominated by completed operations, professional liability for diagnostics and re-engineering, and—on decommissioning—pollution and disposal considerations for panels, inverters, and batteries.

The Solar-Specific Risk Profile

Solar accounts get pushed into the surplus lines (E&S) market because their real-world claims cluster around a handful of exposures that standard forms tend to exclude, cap, or misunderstand. The table below summarizes them.

The encouraging news: property conditions softened in 2026 and new capacity entered the renewable market, so well-documented solar accounts with strong controls are seeing competitive terms. Mitigation you can prove—thicker glass in hail zones, documented torque and racking specs, installer certifications, and clean loss history—translates directly into pricing.

Coverage Lines for Solar Contractors

A complete solar program is built from the same core lines as any specialty contractor account, but the weighting is different: completed operations and inland marine move to the front, and professional/E&O is rarely optional. Here’s the program at a glance.

State-by-State Solar Considerations

Solar underwriting turns heavily on catastrophe exposure—especially hail—plus each state’s environmental and labor environment. Here’s a quick orientation to our eight-state footprint.

For the full multi-sector picture across these states, see the alternative energy insurance hub, and our broader specialty contractor insurance capabilities.

Presenting a Solar Account to Underwriters

How a solar submission is packaged directly determines both how fast a quote comes back and how favorable the terms are. In a market with new capacity and softening property conditions, a clean, complete, well-controlled submission captures the upside; a thin one gets penalized.

The strongest solar submissions include the application, current and expired loss runs, a clear description of the work mix (residential vs. commercial vs. utility-scale, rooftop vs. ground-mount vs. carport), subcontractor practices and certificates, and—critically for hail-belt accounts—the module and racking specifications, glass rating, and any documented torque and QA/QC procedures. Installer certification programs, safety records, and financial statements round out the picture, especially where completed-operations tail and contractor stability are in question.

From there, we match the account to the right wholesale markets, negotiate manuscript terms where standard forms fall short—unrestricted completed operations, appropriate inland marine limits, hail deductible structures—and assemble the full program so the lines fit together instead of leaving gaps at the seams. That coordination is the whole point: the hail-claim scenario at the top of this guide is exactly what happens when completed operations, professional liability, and property coverage are bought in isolation. As a solo specialty producer, the broker who takes your submission is the one who works it start to finish.

Growth Outlook for Solar Contractors

The near-term picture is uneven but the trajectory is intact. Utility-scale solar is expanding on the back of data-center and corporate demand, storage attachment keeps climbing, and the national fleet is on course to roughly double over five years. Residential is working through the tax-credit reset and the consolidation that comes with it—which, for the contractors that survive, means less competition and a larger book of service and warranty work on existing systems.

For insurance, the direction is clear: as projects get larger and lenders more demanding, bankable coverage becomes a condition of doing business, documented catastrophe mitigation becomes a pricing lever, and completed-operations and contractor-stability questions move to the center of every underwriting conversation. The solar firms that treat their insurance program as part of how they win financeable work—rather than a box to check—will be the ones positioned to take on the utility-scale and storage pipeline as it lands.
