Commercial & small business
Insurance is a small but recurring cost most solar budgets need to account for. See a rough estimate of what coverage typically runs.
How it works
Step 1
This is typically the total installed cost. Run that same figure through the commercial solar payback calculator if you haven't already, and check the permitting cost estimator for other soft costs to include.
Step 2
Standard commercial policies don't always account for solar equipment, so this is worth confirming before assuming coverage exists.
Step 3
A broker familiar with solar-specific coverage can quote actual premiums and flag gaps in standard commercial policies. The solar warranty value calculator covers a related but separate protection worth understanding alongside insurance.
A $240,000 system at a typical 0.45% annual premium rate costs about $1,080 a year, or roughly $90 a month. Rates commonly range from 0.3% to 0.6% of insured system value, so actual quotes will vary depending on location, equipment, and coverage details. Insurers like Travelers, which offer specialized coverage for renewable energy customers, note that solar operations face risks distinct from a typical commercial property, from installation-phase builders' risk to ongoing equipment breakdown once the system is operating. Add this recurring cost to the ongoing expenses tracked in the O&M cost estimator for a fuller operating budget picture. Once you have a size in mind, the quick financing comparison tool in our Financing section can help you compare loan, lease, and cash purchase options for the system you just sized.
Sometimes, but many standard commercial property policies weren't written with solar equipment in mind and may exclude it or provide inadequate coverage limits. Confirming with your existing insurer whether the array is properly covered, and at what limit, is an important early step before assuming it's already handled, much like confirming coverage details in the monitoring cost comparison tool before assuming a system is included. The National Association of Insurance Commissioners has published consumer guidance on green energy insurance that specifically flags checking with your insurer before adding solar equipment, since some carriers extend coverage automatically and others don't. Building type is a rough guide at best. The solar panel calculator in our System Sizing section can help you confirm the size from your actual electricity use.
Standard coverage usually includes physical damage from weather events, fire, and vandalism, along with equipment breakdown in some policies. Business interruption coverage for lost production, and liability coverage related to the installation, are often available as add-ons rather than automatic inclusions, similar to how optional coverage tiers work in the O&M cost estimator. Our maintenance and lifespan section covers the equipment-condition side of long-term system health that a good policy is meant to protect against.
Yes, financed or leased systems often come with specific insurance requirements set by the lender or lessor, including minimum coverage amounts and naming them as a loss payee. Reviewing the financing agreement's insurance clause before shopping for a policy avoids buying coverage that doesn't satisfy the lender's requirements, similar to how the solar warranty value calculator can also factor into lender requirements for equipment protection, and the loan term comparison tool in our financing section for the broader loan terms a lender might tie insurance requirements to.
