SunPower is the well known leader in solar module efficiency. It has raised the bar yet again with the release of some super efficient ” X-Series Solar Panels.”As I reported less than one month ago, SunPower now holds the record, and second place, and third place in solar module yield tests. Those records were for SunPower’s E-Series solar panels. Now, SunPower is selling these X-Series solar panels, which have a world record efficiency of 21.5%. The target for these X-Series solar panels is the residential market.
Compared to conventional solar panels, SunPower reports that its X-Series panels should generate approximately 75 percent more electricity over the first 25 years of ownership (on a roof of the same size). By anyone’s standards, that’s impressive.
“The X-Series delivers more energy, higher reliability and superior aesthetics than conventional solar panels. The new world-record efficiency of this product line has received third-party validation by the National Renewable Energy Laboratory (NREL),” SunPower writes.
“The X-Series is made with SunPower’s third-generation Maxeon® solar cells which are built on a solid copper foundation for high reliability and performance. This foundation makes them virtually impervious to the corrosion and cracking that typically degrade conventional panels. As a result, SunPower solar panels are backed by the industry’s first combined 25-year product and power warranty.”
That sounds good, doesn’t it?
