ReneSola Ltd ("ReneSola") (NYSE: SOL), a leading global manufacturer of solar photovoltaic ("PV") modules and wafers, today announced that the Company's 60- and 72-cell polysilicon and monosilicon solar modules exceeded the Company's power output guidelines when assessed by a recent third-party flash test.

In December, Spire Corporation (“Spire”), a leading global provider of capital equipment used in the manufacturing and testing of PV modules and cells, invited ReneSola to participate in a demonstration of the Spire Spi-Sun Simulator™ 5600SLP flash tester, which exposes the modules to a single long-pulse flash of filtered xenon light to approximate solar irradiation. Four ReneSola modules were tested, all of which produced a maximum power output greater than that indicated on the Company’s datasheets, by as much as eight watts. The test results confirmed that ReneSola’s modules perform at least as well as the nominal power outputs and efficiencies stated on the Company’s datasheets.

“Spire has set the industry standard in more ways than one, which is why we were confident the results of this demo would exceed expectations and support ReneSola’s claim that our modules are among the most efficient in today’s solar PV marketplace,” said Kevin Chen, president of ReneSola America. “We can’t emphasize enough the importance of independent testing in identifying top performers in the crowded market for solar products and solutions. Many of our customers also ask to perform their own tests on our modules, which is something we certainly encourage.

“ReneSola has done a remarkable job increasing and improving module efficiencies with its wafer technology, an innovative approach considering others are focused on improving efficiencies through cell technology,” said Steve Hogan, executive vice president and general manager of Spire Solar. “We were thrilled to see ReneSola’s technology on the 5600SLP. Spire’s 5600SLP is the latest in Spire’s metrology tool set, and its extended pulse length and Class A+ (in spectrum, spatial uniformity, and light stability) classification allows for more accurate measurements of advanced technologies such as those held by ReneSola. The results were favorable and we are pleased to have been able to work with ReneSola to demonstrate their performance claims, and prove Spire’s tool capabilities for customers to not sell short their module watts.”

The flash tester used in the demonstration was calibrated with a National Renewable Energy Laboratory (“NREL”) tested and certified module immediately before the testing of ReneSola’s modules. The 5600SLP is the latest and most accurate and repeatable PV module measurement technology available in its class and joins Spire’s simulator product line commonly used by the NREL, Underwriters Laboratories, TUV Rheinland Group, Intertek, and the Florida Solar Energy Center.
