Better Solar Panels
High-Quality Home Solar Panels
When making such an important investment in your home, you want to know the system you choose will live up to your expectations for quality, performance, and reliability—and so do we. That’s why we’ve set our standards extremely high, requiring extensive verification for suppliers, manufacturing and shipment inspections, and panel testing, far beyond the standard.*SunPower works with 3rd party labs and companies to complete testing on panels they offer. Standard testing, as defined by those 3rd parties includes reliability tests of Damp Heat (DH1000), Humidity Freeze (HF10), and Thermal Cycling (TC200).
SunPower Solar Panels
Photovoltaic modules, commonly known as solar panels, are a technology that captures solar power to transform it into sustainable energy.
SunPower offers multiple high-quality solar modules that are rigorously tested for system reliability, performance, and savings. There are many options of solar panels options with varying aesthetics and wattages, but the main two types of solar technology are categorized as follows:
Front-contact solar modules
Also known as "Passivated Emitter and Rear Contact" (PERC), are an advancement on conventional panels with an extra layer within in the back side, allowing some of the sun’s light to be reflected back into the solar cell.
Back-contact solar modules
Known as IBC technology, or “interdigitated back contact”, are highly durable due to a thick layer of tin-plated copper on the back that holds the cell together. Because they do not have contacts on the front of the panel, they provide higher performance due to higher use of the light spectrum.

Frequently asked questions about high efficiency solar panels
How many solar panels will I need for my home?
The number of panels you’ll need for your home will depend on several factors. The easiest thing to do is to look at your electricity bill to get your home’s hourly energy usage, multiply that by the peak sunlight hours for your home (3 to 4 hours on average), and divide by 300, which is an average wattage for solar panels (although they can range from 150 to 370).
Hourly energy usage x peak sunlight hours / 300 = number of panels. This typically ranges from 17-42 panels.
One simple way of answering “How many solar panels do I need” is to let a local solar installer look at your home and give you a quote for system size (including number and wattage of panels), cost, and estimated annual and lifetime savings. Let our Solar Advisors match you with the perfect SunPower installer in your area. Read more about determining number of panels on our blog.
Which is the best type of solar panel?
There are several types of solar technology, but almost all home solar panels use crystalline silicon (monocrystalline or polycrystalline). The main difference is the purity of the silicon.
Monocrystalline silicon is made from a single-crystal, and polycrystalline silicon is made by melting silicon fragments together. In monocrystalline panels, there are fewer impurities, so the electrons are less likely to get blocked before leaving as electricity, thus these panels are “more efficient” or better at turning sunlight into electricity.

Do solar panels wear out over time?
In short, yes. Your roof isn’t a very hospitable place, so conventional solar cells lose power over time because of corrosion and breakage.
SunPower has rigorous testing and quality assurance standards to optimize performance and reliability. That’s why we offer our industry-leading Complete Confidence Warranty.
