27 Jun SunPower sets new solar panel efficiency record
American energy company SunPower (NASDAQ:SPWR) has set a new solar power panel efficiency record, validated by the US Department of Energy’s National Renewable Energy Laboratory (NREL).
After reaching 22.8% efficiency for its X-Series solar panel earlier this year, SunPower has reached 24.1% efficiency – exceeding the previous world record for the highest efficiency of a solar panel using silicon cells.
Peter Cousins, senior vice president of research, development and deployment at SunPower said: “SunPower’s world record efficiency panels offer customers the best value for energy and superior aesthetics due to our unique architecture.”
NREL evaluates renewable energy and energy efficiency technologies and maintains the industry’s accepted chart of records. This particular module was made using laboratory solar cells of 25% mean efficiency and builds on the commercially available SunPower X-Series architecture, moving the design forward to the next level.
“SunPower’s X-Series panel was tested by our lab under standard test or reporting conditions,” explained Keith Emery, NREL scientist. “The module measured 11310.1 cm (aperture area) and had a power of 272.5W. We recorded 24.1% efficiency, which is a new record for silicon module efficiency.”
SunPower’s X-Series panel produces up to 70% more energy in the same place over the first 25 years compared to conventional solar panels with efficiencies that range from 15-18%.
