Why a manufacturer warranty isn’t enough

Here’s how the two systems we install most often compare. Each manufacturer’s coverage ends at a different time, and labor is usually the first to go. SI-30 picks up where each one stops and carries parts and labor to year 30.

SI-30 also adds roof reseal and protection if a manufacturer goes out of business, from day one. Manufacturer terms shown are their published limited warranties as of 2026 and can change.

What SI-30 covers

Everything below comes in one warranty, with nothing extra to pay along the way.

Parts and labor

Panels, inverters, optimizers and racking from approved manufacturers, plus the labor to repair or replace them.

Roof reseal and reflash

If a leak shows up within 3 inches of where your solar array is mounted, it’s resealed and reflashed.

Manufacturer default protection

If an equipment maker goes out of business, your coverage continues. It’s backed by an A.M. Best A+ rated insurance carrier.

Battery replacement SI-30 Total

Diagnostics and repair, plus one battery replacement if capacity drops below 50% after the manufacturer’s warranty ends.

Transfers with your home

The warranty is tied to your address, so it passes to the next owner at no cost if you sell.

Zero hidden fees

A $0 deductible, no subscription and no onboarding fees.

Common questions

Is SI-30 the same as my manufacturer warranty?

No. It works alongside it. Manufacturer warranties mainly cover the part itself. SI-30 adds the labor to repair or replace covered equipment, resealing and reflashing of roof leaks within 3 inches of a solar mount, and protection if a manufacturer goes out of business, all for 30 years.

What happens to the warranty if I sell my home?

The warranty is assigned to the address, so it transfers to the new owners at no cost.

Are there deductibles or monthly fees?

No. SI-30 coverage has a $0 deductible, no subscription and no onboarding fees.

What equipment qualifies?

Coverage applies to products from manufacturers on Solar Insure’s Approved Vendor List. We’ll confirm your equipment qualifies when we design your system.

Can I add SI-30 to a system I already have?

SI-30 Solar and SI-30 Total are for new systems. If you’re adding a battery to a home that already has solar, SI-30 Battery covers new and retrofit battery installations.
