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.
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.
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.
