More power means fewer panels

With SunPower^® solar panels you can install more power in the same amount of space than with other panels: up to 50% more solar power than conventional designs and up to four times more than thin-film solar. Since our commercial solar systems require significantly less roof space, you can use fewer panels to produce the same amount of clean, renewable solar power. With fewer solar panels you can also maximise your roof space to choose the best, unobstructed location for electricity production.

More electricity in real-world conditions

SunPower panels outperform others early in the morning, late in the day, and on cloudy days.
They effectively absorb different wavelengths of light to generate more electricity.
They perform better at high temperatures than others. As they're more efficient at converting light into electricity (and not heat), the hotter it gets outside, the better they perform.
They maintain efficiency during initial break-in. Most panels lose 3% efficiency when first exposed to sunlight. This is not the case for SunPower panels.

Independent tests confirm SunPower produces the most electricity

Universities and independent research laboratories around the world compared the performance of solar panels from SunPower against other technologies. In each case, SunPower solar panels were the clear leader.
