Clear, No‑Fine‑Print Warranty

Inverter: 10 years – full replacement, not pro‑rated

Mounting hardware: 5 years against corrosion or breakage

Cables and connectors: 3 years

We do not ask you to ship heavy parts back at your expense. For defective components, we send a replacement immediately and provide a return label for the faulty unit.

Lifetime Technical Support

You can call, email, or use our web form anytime. For installation questions, we offer scheduled video calls where our technician looks at your setup via your phone camera. For operational issues, most are resolved in under 20 minutes.

5‑Year Spare Parts Availability

Even after your warranty expires, we guarantee to stock replacement parts for your kit for at least five years. You will never be left with an unrepairable orphan system.

Easy Upgrade Program

When you are ready to add batteries or more panels, we offer a trade‑in credit for your old inverter (if still functional) toward a newer model. Existing customers also receive discounted shipping on expansion components.

Free Annual Performance Review

Each year, we email you a simple report comparing your actual solar production to the estimate we provided before purchase. If production is lower than expected, we help you diagnose the cause – shading from new tree growth, dirty panels, or a neighbor's new building.
