The SunPower® Complete Confidence Warranty is the only home solar warranty to cover your whole system (not just the panels), so you never have to wonder which company you can depend on.

SunPower® is the only company that stands behind your entire system, not just the panels. We also:

• Provide repair or replacement at no additional cost; Labor, shipping, parts – we take care of everything!
• Don’t require receipts, proof of purchase or written claims
• Cover rust damage, such as in seaside installations
• Treat the system as a whole

SunPower® covers 100% of repair or replacement costs, while conventional solar warranties don’t. Labor, shipping, parts – we’ve got your covered for 25 years. Plus we guarantee that your panels won’t lose more than 8% of their original DC power output in 25 years. Compare that to 19% for conventional solar.

A 25-year complete system warranty as strong as the company behind it. A solar energy system may be one of your biggest home improvement purchases. You should only have to pay for it once. Panasonic AllGuard warranty protects your solar investment for 25 years, top to bottom. AllGuard covers labor for your entire system, including solar panels, inverters, racking and monitoring hardware. Should any component of your solar system malfunction – from the racking to the panel and everywhere in between – we’ll promptly fix it no questions asked.
