Solar Insure introduces 30-year residential solar battery warranty

US-based solar and energy storage warranty provider Solar Insure has announced a 30-year battery warranty for installers to offer residential solar and storage customers.

The warranty addresses customer support for battery energy storage systems (BESS), which typically last around five to 15 years, significantly shorter than the 25-plus years expected of most solar panels.

The new SI-30 battery warranty includes 30 years of protection for parts, labor, and diagnostics for BESS issues. The warranty also includes a manufacturer default protection, backed by an A-plus-rated insurance carrier assessed by US ratings agency AM Best.

The product also includes a battery replacement for solar customers if their BESS falls below 50% capacity during years 11 to 30.

Solar Insure said the warranty is assigned to a customer’s address, enabling it to be transferred to a new homeowner with no additional costs. The company said the product has no “hidden fees” for aspects such as onboarding, subscriptions, or a deductible amount.

“SI-30 Battery represents a shift in how the industry approaches energy resilience,” said Dean Chiaravallotti, chief revenue officer at Solar Insure. “By providing homeowners with assurance in their battery investment, we enable solar providers to build long-term trust and provide lasting value.”

Battery attachment rates in residential solar installations have increased steadily, from about 8.1% in 2020 to around one-in-four systems today, according to Solar Insure. In California, the United States’ leading residential solar market, batteries are now included in more than half of all PV installations.

Solar Insure also said it has added six new solar and energy storage manufacturers to its approved vendors list for warranties: EG4 Electronics, Fortress Power, FoxESS, Lunar Energy, PointGuard, and QCells.
