What sets SunPower by MJM Solar Energy apart?
SunPower solar panels outperform conventional panels by producing 55% more energy within the same space over a 25-year period. This translates to reduced monthly energy costs and a quicker return on your solar investment.
SunPower solar panels stand out with their robust 25-year warranty—the best in the industry. While other brands typically provide a 12-year warranty with deductibles, SunPower eliminates deductibles altogether. And here’s the bonus: If you sell your home, the warranty remains valid for the next owners.
In addition to the warranty, SunPower provides a performance guarantee. Their solar panels retain 98% of their original power in the first year. Subsequently, the power decreases by no more than 0.25% annually for the next 24 years. Compared to most panels with a 0.5% annual loss, SunPower panels excel with only half that rate.
MJM Solar Energy is a SunPower Master Dealer—the only one in Maryland, Virginia and Delaware. Out of the 850 accredited SunPower dealers, only 35 hold this prestigious title. We’re in the top 5% of SunPower dealers nationwide.
