Will a solar installation roof lease increase my insurance costs or put my coverage at risk?
Will a solar installation increase my insurance costs or put my coverage at risk?
If you're a commercial real estate owner considering rooftop leasing for solar, insurance is one of those practical questions that deserves a clear answer. The short version? Solar installations typically have minimal impact on your insurance premiums—and with the right structure, they shouldn't increase your risk at all.
Let's break down what you need to know.
The direct answer: Most CRE owners see little to no insurance premium increase
When you lease your rooftop to a solar developer as part of a community solar program, the developer owns and operates the solar system. In most cases, the developer carries the primary insurance for the solar installation itself—including equipment damage, performance issues, and liability related to the system.
Your building's property and liability insurance may need to acknowledge the installation, but insurers typically view properly installed, code-compliant solar systems as low-risk improvements. Industry data shows that premium increases, if any, are usually less than 1-2% of your existing property insurance costs—a negligible expense compared to the predictable cash flows you'll generate from the rooftop lease.
How solar installations actually affect commercial property insurance
What changes (and what doesn't)
What typically stays the same:
- Your core building insurance coverage
- Your general liability protection
- Your business interruption coverage
Your insurer will want to know about the installation, but they're primarily concerned with three things:
- Is the system installed by a licensed, insured contractor?
- Does it meet local building codes and engineering standards?
- Who owns the equipment and carries primary liability?
When you work with vetted solar developers through a competitive developer marketplace, these boxes are checked automatically.
What your insurer will ask for
Expect your insurance carrier to request:
- Certificate of Insurance from the solar developer showing they carry adequate liability coverage (typically $1-5M, depending on system size)
- Named insured or additional insured status on the developer's policy for your building
- Engineering certifications confirming the roof can support the additional load
- Documentation that the installation meets electrical and building codes
- Compliance with enhanced design standards when FM Global is the insurer.
These are standard requirements that experienced solar developers provide as part of every project. Your Lumen Advisor coordinates these documentation requests, so you're not chasing paperwork across multiple parties.
The risk profile: Why solar is actually low-risk for insurers
Commercial insurers have decades of data on rooftop solar installations, and the track record is strong:
Fire risk is minimal. Modern solar systems include multiple safety disconnects, arc-fault protection, and are installed by licensed electricians following strict electrical codes. The National Fire Protection Association reports that solar-related fires are extremely rare—less than 0.006% of installations annually.
Wind and weather damage is rare. Solar racking systems are engineered to withstand local wind loads and weather conditions. Professional installations include structural engineering review to ensure your roof can safely support the system in all weather scenarios.
Liability exposure is on the developer. Because the solar developer owns and maintains the system, they assume liability for equipment failure, performance issues, or any injuries related to installation or maintenance work.
From an insurance perspective, a well-executed solar installation is far less risky than many other rooftop uses—HVAC equipment, rooftop dining, event spaces, or telecommunications equipment.
What about system damage or removal costs?
This is where the structure of your agreement matters.
In a typical rooftop lease arrangement:
- The developer insures their own equipment against damage from fire, theft, vandalism, or weather events
- The developer is contractually responsible for removal and disposal at the end of the lease term
- If your roof needs repairs or replacement during the lease, the developer is typically required to remove and reinstall the system at their expense (though specific terms vary by contract)
Your property insurance covers your building, just as it always has. The solar equipment is the developer's asset and their insurance responsibility.
A modern solar broker reviews these terms during the bid process to ensure you're protected. We sit on your side of the table, so insurance obligations and indemnification language get the scrutiny they deserve before you sign anything.
Key questions to ask during your bid process
When evaluating proposals from solar developers, make sure your Lumen Advisor helps you confirm:
- What liability limits does the developer carry? (Minimum $2M general liability is standard; larger projects may require $5M+)
- Will you be named as additional insured on their policy? (This should be non-negotiable)
- What happens if the roof needs repair during the lease term? (Look for clear language about system removal and reinstallation at developer expense)
- Who covers damage from installation work? (The developer's contractor should carry workers' compensation and completed operations coverage)
- Is there an abandonment bond or decommissioning reserve? (This protects you if the developer goes out of business)
Investment-grade financial analysis includes reviewing these risk-transfer provisions so you're not exposed to unforeseen costs.
Bottom line: Insurance shouldn't be a barrier to rooftop revenue
For commercial real estate owners evaluating rooftop leasing opportunities, insurance concerns are valid—but they're also manageable and well-understood by the industry.
With proper contract structure and experienced developers, solar installations:
- Add minimal cost to your existing insurance premiums
- Transfer equipment and liability risk to the developer
- Require standard documentation that professional developers provide routinely
The key is working with an end-to-end partnership that understands real estate operations, not just solar technology. When you turn underutilized rooftops into predictable revenue streams, insurance should be a checkbox, not a roadblock.
