Most solar panels on the market have an average efficiency rating of 14%.

This number represents the panel’s efficiency of converting the sun’s energy into power. SunPower solar panels use Maxeon Cell Technology and have efficiency ratings of 18%-20%. For this reason, SunPower panels produce up to 50% more power than conventional solar panels. And it doesn’t stop there: SunPower’s superior technology allows the panel to perform in a series of conditions that other panels can’t handle.

Low-Light Conditions

SunPower panels turn on earlier and shut down later than conventional solar panels. SunPower panels also perform impressively in overcast and rainy conditions. High-Heat Conditions: Most might say that a hot sunny day is the ideal solar-production day—but because of the limitations inherent in conventional solar, some panels underperform and might shut down in high-heat conditions. The Maxeon technology in SunPower panels allows it to outperform conventional solar in this environment.

Break-In Period

Because of how conventional solar is manufactured, it undergoes a “break-in period.” This period is when conventional solar is turned on and allowed to produce power. Conventional solar panels lose 3% of their efficiency and never recover it. Thankfully, SunPower panels never experience “break-in.”
All these advantages save the consumer money, both immediately and over time.
