We love SunPower’s best-in-class warranty, quality construction and terrific monitoring app, but our favorite thing about the company is their solar panel efficiency. Good Energy Solutions is the only SunPower Elite Dealer in Kansas and Missouri.
Several respected publications have rated SunPower as producing the most efficient solar panel on the market, including Solar Edition, EcoWatch, Solar Reviews, Energy Sage and Clean Energy Reviews. These solar reviewers based their findings on build quality, reliability and most importantly efficiency.
Solar efficiency describes a panel’s ability to convert sunlight into electricity. The higher the efficiency, the more electricity a solar panel generates. Designed in a California facility with SunPower, Maxeon solar cell technology makes more energy from sunshine than its competitors.*
Conventional solar cells lose power over time because of corrosion and breakage. The unique design of SunPower solar cells eliminates 85% of the reasons conventional cells normally fail. Commonly, this is referred to as degradation. Most solar panels lose .5% of their power production every year, meaning that after 20 years, they produce 10% less power. However, premium manufacturers like SunPower offer panels with degradation rates as low as 0.25% per year, which means their panels will last much longer than most other manufacturers.
