Other companies may try to tell you their warranty is as good as SunPower’s, but make sure you read the fine print. Here are a few questions to ask:
Is this one warranty or four? Is one manufacturer standing behind your entire system? Chances are, you are actually being offered warranties from each of the companies that make the components of your system. Do you want to referee whether a problem is with your solar panels, inverter, racking, or monitoring? With SunPower, you only have one company to call.
Does the warranty cover parts, labor, and shipping? In the unlikely event you ever need to make a warranty claim, SunPower will not only replace your equipment, but it will also pay for any shipping and labor necessary for a replacement. Most other solar warranties make you pay for labor and shipping.
What is the warrantied rate of solar panel degradation? All solar panels degrade over time. But SunPower guarantees no more than 0.25% degradation per year, versus a typical 0.70%. That may not seem like much of a difference, but over decades it means a SunPower system will produce far more energy than any other system.
Does the panel warranty cover both power production and the panel itself? Your salesperson may mention a “25-year warranty”, but it is common for such warranties to cover only power degradation, not product failure. With many other panel manufacturers, the actual product warranty is only 10 years. SunPower’s is 25 years.
