Frequently asked questions.
We’re here to address any concerns you might have on your path to solar. Here are some common questions. If you don’t find your answers here, we’re a phone call away!
A working solar system is composed of many components that work together to turn sunlight into usable power for your home. When you buy a SunPower® solar system with components that are designed and engineered to work together, you get the confidence of knowing that not only will the system work better together, but also that, should anything go wrong, you have one company, SunPower, backing your entire system – not just a component. If there is an issue, you have just one phone call to make.
While length of coverage is important, it’s even more important to understand the comprehensiveness of the coverage. If something goes wrong with your system, is there one company to contact, or will you have to juggle amongst multiple manufacturer warranties, each of which is responsible for only one component of your system? Can you simply pick up the phone, or are you required to send a request for help to a P. O. Box in a distant location and wait an extended period of time to receive help? Will a representative inspect the system at your home, or will you be expected to ship a faulty component, at your expense? Do you have peace of mind knowing that your system will be fixed at no extra cost to you, or will you be billed for extra charges such as labor or shipping? These are only some of the considerations that SunPower took into account when creating our industry-leading Complete Confidence Warranty.
I saw that another brand offers a warranty that also provides 25 years of coverage. Is this the same as SunPower’s warranty?
Other manufacturers, many of which are new to manufacturing solar, are trying to catch up to SunPower’s 30+ years of dedicated solar experience and to the exceptional terms of our Complete Confidence Warranty. Many of them include hidden charges, such as shipping and labor costs, and don’t cover all of the many parts that go into a working solar system – panels, inverters, racking system, monitoring hardware and software. SunPower is the only company that offers one comprehensive product, power, and labor warranty for all components, because we engineered and designed the entire system.
Why does SunPower claim to have the best power warranty in the industry and how does this benefit me?
Over time, all solar panels lose a small amount of production, measured by its annual degradation rate. SunPower panels have the lowest degradation rate in the industry, validated by 3rd party testing. This means that a system with SunPower panels can produce more power and we back this with our 25 year Complete Confidence Warranty.
Homeowners should be suspicious of product and power warranties with separate lengths of terms. Product warranty covers defects and power warranty covers how much power the system is producing. What’s the value of a longer power warranty if the product generating the power breaks but is no longer warranted?
The “efficiency” of a solar panel determines how much power can be generated in the same amount of space (power density). Some solar panels try to compensate for lower efficiency by creating larger-sized panels to increase wattage, but this does not solve a homeowner’s power needs since the home’s available roof space cannot change. SunPower’s high efficiency panels produce more power in the same roof space than conventional panels.
