SAN JOSE, Calif., April 3, 2013 /PRNewswire/ -- SunPower Corp. (NASDAQ: SPWR), a global solar energy and technology provider, today introduced its SunPower X-Series Solar Panels (X-Series), a new product line for the residential market that offers an unprecedented 21.5 percent efficiency. 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).
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.

Features include:
- High energy output with no light induced degradation
- Better low-light and spectral response, generating electricity earlier in the morning and longer in the evening
- Low temperature coefficient, allowing for more electricity generation on hot rooftops
