Back-Contact innovation, refined over 40 years, designed to bring more reliable clean energy to your home.
Most panels run metal wiring across the front of every cell, where it blocks the sun. SunPower moves it to the back, so the whole panel does one job, catching sunlight.
Edge-to-edge maximized active surface
Back-contact shingled cells
Back-contact shingled architecture removes visible front connections and gaps to offer a clean Edge-to-Edge high-use surface.
A durable cell and panel architecture engineered with all the wiring at the back, for demanding real-world conditions.
Its sleek black appearance integrates naturally with traditional and contemporary residential roofs.
Higher efficiency, better in shade and a longer warranty with lower degradation add up over the life of the system.
More electricity without needing extra panels. Ideal when roof space is limited.
No visible wiring, no grid lines, no gaps. A sleek all-black surface that blends into your roofline.
More energy at dawn, dusk and on cloudy days. Steady output whatever the weather.
Backed by a best-in-class 40-year warranty covering product, power and service.
Higher efficiency, better in shade and low light, a longer warranty with lower degradation - adding up over the life of the system. More energy for a lifetime.
Low temperature coefficient 0.26%/°C
Up to 12.3% performance
Protected up to 40mm at 27.5m/s
Safer & longer lasting performance
IEC 61701 accredited
Just 0.25%/yr degradation

SunPower pioneered back-contact solar technology decades ago. Today that engineering is combined with TCL’s global manufacturing scale. Behind every panel is 40+ years of refinement, field data and real-life performance that other back-contact panels haven’t had time to earn.
* Tested and approved on millions of homes for decades
Back-contact technology is becoming the industry’s new benchmark. Here’s what sets SunPower apart.
| Conventional | Other back-contact | SunPower Origin | Why it matters | |
|---|---|---|---|---|
| Edge to edge shingled | Lost space between cells | 90-95% | 95% active panel surface | Pack more energy in less space - ideal for constrained roofs or large energy needs |
| Visible wiring | Front-facing grid lines | None | None | Cleaner look on your roof, nothing to catch dirt or shade cells |
| Efficiency | Lower | Varies* | Industry-leading up to 25% | More power from the same roof space, so you need fewer panels |
| Heat performance | Higher power loss in heat | Varies* | 0.26%/°C coefficient | Keeps producing power on the hottest days, when you need it most |
| Degradation | Faster power loss over time | 0.35%/year | Industry-lowest 0.25%/year | Your system stays productive for decades, protecting the return on your investment |
| Track record | - | New to market | 40+ years proven | Confidence that the technology and the company will be around to back it |
| Warranty | Typically 25 years. No service included | 25/30 years. No service included | 40 years: product + power + service | One warranty covers everything, no gaps, no separate claims to chase |
Many solar warranties split coverage into separate clauses for the panel and its performance, leaving a grey zone where manufacturers can dispute which one applies. SunPower’s 40-year warranty covers both as one promise. And because SunPower has legal entities in Europe and in your own country, your SunPower Partner is right here to support you, from installation through year 40.

Did you know?
Many warranties make you prove whether a problem is “product” or “performance” before covering it. SunPower covers both together. No debate. No grey zone.
