Solar Power, Inc.’s SP200 Modules Receive Stellar Efficiency Rating from California Energy Commission

ROSEVILLE, Calif.--(BUSINESS WIRE)--Solar Power, Inc. (“SPI”) (OTCBB:SOPW) announced today that its 200 watt modules have been given one of the highest performance ratings awarded by the California Energy Commission (“CEC”). The Modules were tested by Intertek, an independent, Nationally Recognized Testing Laboratory (NRTL) to determine real world performance characteristics. The test results are used by the CEC to rank and rate solar module performance for the CEC’s California Solar Initiative (CSI). Solar panel performance and output are an important part of the CSI rebate program. A higher performance rating qualifies for greater rebates on the part of home and business owners installing solar systems within the state of California.

“We are very pleased with the performance rating our SP200 module has been awarded by the CEC,” said Jack Patton, Chief Technology Officer for Solar Power, Inc. “The California solar market is growing, and having one of the top performing modules to offer Californians is significant. Our modules are being used across the state in a variety of applications that cover the spectrum of users from homeowners to commercial enterprises that include the STAPLES Center and Nokia Theatre in Los Angeles. This ranking is a reflection of our dedication to quality and is beneficial to all of our customers.”

Solar Power, Inc.’s SP200 multi-crystalline module was tested under strict controls using Photovoltaic USA Test Conditions (“PTC”) at the Intertek laboratories in Lake Forest, CA to achieve the PTC rating. The PTC rating provides a measurement of how the module will behave in real-world conditions and is widely recognized by solar professionals as the best way to compare module performance. The CEC currently lists 20 modules that have been tested using the PTC test conditions. Solar Power, Inc.’s SP200 module is ranked number three by the CEC, placing it in the upper echelon of top performing modules within its class on the market today. The PTC performance ratings among the top three modules are tightly clustered. The performance difference between the number one ranked module and Solar Power, Inc.’s SP200 is one-third of one percent.

All SPI modules are UL listed for the US market and IEC rated for the European market. The SP200 modules are also sold through the company’s growing U.S. national franchise network of Yes! Solar SolutionsTM retail energy outlets under the Yes! Solar SolutionsTM brand name. Additionally, Solar Power, Inc.’s SP200 modules are sold throughout Europe and Asia for both residential and commercial solar energy systems.
