BEDFORD, Mass., May 25, 2010 (BUSINESS WIRE) --Spire Corporation (Nasdaq: SPIR), an American global solar company providing capital equipment and turnkey manufacturing lines to manufacture photovoltaic (PV) modules, today announced that Underwriters Laboratories (UL) has once again selected Spire's world class SPI-Sun Simulator(TM) 4600SLP as a standard to test and certify PV modules. Already in use at UL facilities in the United States, China, and Germany, the Spire Simulator will now serve as the primary test equipment gauge at the new UL facility in Bangalore, India.

Spire's simulators have become the benchmark for PV module testing with a majority of the world's manufactured modules tested with Spire simulators, both crystalline silicon and thin films. With a Class AAA rating, Spire's simulators can provide high-volume production with a low cost of ownership. Spire's proprietary method of controlling the simulator's pulse or flash length, large irradiance range, and superior spectral control, allow test labs the ability to measure modules beyond their own test standards and understand critical aspects of their performance.

"We have set the bar very high with our SPI-Sun Simulators," said Roger G. Little, Chairman and CEO of Spire Corporation. "I am pleased to know that test agencies such as UL, NREL, TÜV, FSEC, CSA, KIER, Intervac, and Bodycote all use our simulators as their standard."
