Which Insurers Offer Professional Liability for Renewable Energy
Professional liability coverage for renewable energy is available from a smaller set of carriers than general liability, because the risk profile is specialized. The insurers who write this coverage fall into three groups: national carriers with dedicated renewable energy underwriting teams, regional insurers who focus on energy and construction, and specialty carriers who write only energy-related risks.
The major national carriers offering professional liability for renewable energy include Travelers, Hartford, Zurich, and CNA. Each has underwriters who understand solar installation, wind turbine maintenance, energy storage design, and grid integration work. Regional carriers like Everest, Arch, and XL Catlin also write this coverage. Specialty carriers such as Hiscox and Beazley have renewable energy practices, though their appetite varies by project type and company size.
The carrier you can actually bind coverage with depends on three things: your specific service (design, installation, maintenance, consulting), your company's revenue and claims history, and the state where you operate. A solar installer in California will find more options than a geothermal consultant in a rural state. Your insurance broker can run your profile against the current appetite of each carrier—this changes quarterly as underwriters adjust their risk tolerance.
Key Takeaways
- Travelers, Hartford, Zurich, and CNA are the primary national carriers writing professional liability for renewable energy companies.
- Your ability to bind coverage depends on your specific service type, company size, and geographic location, not just on which carriers exist.
- Specialty carriers like Hiscox and Beazley write renewable energy coverage but often have narrower appetites and higher minimums than national carriers.
- Underwriting appetite for renewable energy shifts quarterly, so a carrier who declined you six months ago may be open now, or vice versa.
- A broker who works regularly with renewable energy clients will know which carriers are actively writing and which are restricting new business.
What Professional Liability Covers in Renewable Energy
Professional liability covers claims that your design, information, or installation caused financial loss to a client—not bodily injury or property damage, which general liability handles. In renewable energy, this typically means a solar array you designed underperformed, a wind turbine installation you supervised had structural flaws, or energy storage system specifications you provided created safety or performance issues.
The coverage pays for the cost of defending the claim and any judgment or settlement, up to your policy limit. It also covers claims-made expenses: the cost of informed witnesses, engineers to review your work, and legal fees. Most policies include a retroactive date, which means claims arising from work you did before the policy started are not covered unless you purchased tail coverage when you switched insurers.
Coverage does not extend to bodily injury (that is general liability), property damage you caused (also general liability), or contractual liability you assumed in a contract without telling your insurer. It also does not cover claims arising from failure to obtain required permits, violations of building code, or work performed without proper licensing—these are excluded because they represent negligence in your core business function, not a professional error.
How Underwriters Assess Renewable Energy Risk
Underwriters evaluating your company look at five factors: the type of renewable work you do, your team's certifications and experience, your claims history, your contract language, and whether you carry general liability. A solar design firm with ten years of history and no claims will get a quote; a startup with the same credentials but no track record will not, or will face a much higher premium.
Certification matters more in renewable energy than in many other fields. Underwriters want to see NABCEP (North American Board of Certified Energy Practitioners) certification for solar installers, AWEA (American Wind Energy Association) training for wind work, and PE (Professional Engineer) stamps on design documents. If your team lacks these, some carriers will decline outright; others will offer coverage at a higher rate or with a higher deductible.
Your contracts are also underwritten. Carriers review whether you have indemnification clauses (where you agree to cover the client's losses), whether you limit your liability in the contract, and whether you disclaim warranties. A contract that promises performance guarantees or assumes unlimited liability will either be declined or priced much higher. Your broker should send sample contracts to the underwriter before you explore, not after.
Differences Between Carriers in Appetite and Pricing
Appetite varies significantly. Travelers and Hartford have broad appetite for solar installation and design across most states. Zurich and CNA are more selective—they may write solar but decline wind, or write new construction but decline retrofit work. Specialty carriers like Hiscox often have higher minimum revenues (sometimes $500,000 or more) and may focus only on design or consulting, not installation.
Pricing also varies by carrier philosophy. Some carriers price based on revenue alone; others factor in your claims history heavily. A company with $2 million in revenue and no claims might pay $1,200 annually with one carrier and $2,500 with another. The difference reflects how much risk the underwriter believes you represent, not a mistake in the quote.
Deductibles range from $1,000 to $10,000 depending on the carrier and your risk profile. Higher deductibles lower your premium but mean you pay more out of pocket if a claim occurs. Some carriers offer a choice; others set the deductible based on your company size and history. Ask your broker what deductible options each carrier offers before you compare premiums.
How to Find a Carrier and Get a Quote
You cannot contact most professional liability carriers directly. They work through insurance brokers who have relationships with underwriters. A broker licensed in your state can submit your information to multiple carriers at once and tell you which ones will quote and which will decline.
To get a quote, you will need to provide: your company's legal structure and years in business, a description of the specific services you offer (solar installation, wind maintenance, energy storage design, etc.), your annual revenue and number of employees, your team's certifications, a sample contract you use with clients, and your claims history for the past five years. If you have no claims, say so—that is a positive signal to underwriters.
The broker will submit this information to carriers and receive quotes within one to three weeks. Each quote will show the annual premium, deductible, policy limits, and any exclusions or conditions specific to your company. You can then compare not just price but also the scope of coverage—some carriers exclude certain types of work or geographic areas.
What Happens If a Carrier Declines You
If the carriers your broker approaches decline, it usually means one of three things: your company is too new (less than two years in business), your team lacks required certifications, or your claims history is poor. A decline is not permanent. You can reapply after addressing the issue—for example, after your lead installer obtains NABCEP certification or after two years have passed since you started.
In the meantime, some brokers can place you with a surplus lines carrier, which is an insurer licensed to write risks that standard carriers will not take. Surplus lines coverage is legal and legitimate, but it typically costs 30 to 50 percent more than standard market rates and may have higher deductibles. It is a bridge until you can move to a standard carrier.
Another option is to join a group or association policy if your industry has one. Some renewable energy trade associations negotiate group professional liability policies for members. These policies have looser underwriting than individual policies and may accept newer companies or those with limited certifications. Ask your industry association whether they offer this.
State Variations and Licensing Requirements
Professional liability coverage availability varies by state because licensing requirements for renewable energy work differ. California requires solar installers to be licensed contractors; other states do not. A carrier may write solar installation in California but decline it in a state with no licensing requirement, because the lack of regulation creates uncertainty about competency.
Some states have specific requirements for energy storage system design or wind turbine work. Underwriters in those states are familiar with the regulatory environment and more willing to write the coverage. In states where renewable energy work is less common, fewer carriers have underwriting informed, and those who do may charge more.
If you operate in multiple states, your broker should confirm that your policy covers work in all of them. Some policies exclude certain states or require separate endorsements. This matters if you bid on projects across state lines or have employees in multiple locations.
Frequently Asked Questions
Does professional liability cover me if a solar panel I installed catches fire?
No. Fire or property damage is covered by general liability, not professional liability. Professional liability covers claims that your design or installation caused financial loss—for example, the system underperformed and the client lost money. If the panel itself fails and causes damage, that is a product liability or general liability claim, which requires different coverage.
What if I am a one-person consulting firm—can I get professional liability?
Yes, but you may face higher premiums or stricter underwriting. Carriers want to see that you have errors and omissions insurance (another name for professional liability) and that you carry general liability as well. Being solo does not disqualify you, but it means underwriters will scrutinize your contracts and certifications more closely. A PE license or NABCEP certification strengthens your process significantly.
If I have general liability, do I need professional liability too?
Yes. General liability covers bodily injury and property damage; professional liability covers claims that your information or design caused financial loss. They protect against different types of claims. A client injured during installation is a general liability claim. A client whose system underperformed because of your design is a professional liability claim. You need both.
Can I get professional liability if I have had a claim in the past?
Yes, but it will affect your premium and underwriting. Carriers ask about claims in the past five years. One claim does not automatically disqualify you, but it will raise your rate or deductible. Multiple claims or a large claim may make you uninsurable in the standard market, in which case a surplus lines carrier may be your option. Be honest about your history—misrepresenting claims is grounds for the carrier to cancel your policy later.
How often should I review my professional liability coverage?
At least annually, or whenever your business changes significantly. If you add a new service (for example, you start doing energy storage design in addition to solar installation), tell your broker when ready. If your revenue grows substantially or you hire new staff, your coverage limits may need to increase. Underwriting appetite also shifts, so a carrier who declined you last year may be open now, which could mean better rates or terms.
