SunPower makes the highest efficiency solar panels with the new Maxeon 400 reaching 22.6%. SunPower holds the world record for the highest efficiency silicon solar panel. Designed by SunPower in California, Maxeon® solar cell technology makes more energy from every drop of sunshine.
Factor in our elegant styling and impressive durability, and it’s no wonder we outshine the rest.
Founded in 1985 as a Silicon Valley pioneer & committed to innovation: Over 500 patents
No Grid Lines on Front of Cell: Maxeon cells absorb more sunlight and look incredible on your roof.
Solid Copper Backing: Our thick copper foundation adds massive strength and is almost impervious to corrosion.
Thick Connectors: Expanding and contracting from daily temperature swings are no problem with our built-in strain relief.
Efficiency: SunPower technology captures more light
- No front gridlines—nothing to block light
- Premium mono-crystalline construction
- Wide, thick metal contacts conduct more current
- Backside mirror reflects light back into the cell
- AR glass keeps more light in; reflects less away
- Performs better in high and low temperatures see more
- Maintains performance level better over time
- Absorbs more colors in the spectrum
- Captures more sunlight in low-light conditions
- AR glass allows panels to capture more diffuse and oblique light

SunPower expects its modules (panels) have a useful life of more than 40 years, defined as 99% of modules producing at least 70% of their power. This is made possible through fundamental design differences which provide robust protection against real-world stresses. These differences are discussed in the context of comparative experimental data. In addition, SunPower’s physics-based model, PVLife, provides the expected change in performance over time from major degradation and failure modes. This model matches well with field data. Collectively, these data suggest that a 40 year life is realistic useful

SunPower is proud to offer a 25-year warranty as efficient and dependable as our solar panel technology. In the unlikely event that you have an under-performing solar panel, we will repair or replace the panel and reinstall it on your home
