Rochester Hills, Mich., May 18, 2010 – UNI-SOLAR, a wholly-owned subsidiary of Energy Conversion Devices (NASDAQ: ENER), today announced it is participating in one of the country’s largest rooftop testing sites for photovoltaic (PV) modules. The test site, hosted by ProLogis Renewable Energy, is on a utility-scale rooftop in Denver, Colorado.

UNI-SOLAR is based in Michigan with innovative technology and manufacturing facilities in Auburn Hills and Greenville. UNI-SOLAR is the only large-scale manufacturer of lightweight, flexible thin-film photovoltaic products in the U.S.

ProLogis is a leading global provider of distribution facilities, with more than 450 million square feet of roof space worldwide available for solar photovoltaic installations. UNI-SOLAR already has 4.7 MW of PV installations active, or soon to be this year, on the grid on additional ProLogis rooftops in the USA (3.5 MW), Spain (5 MW) and France (0.7 MW).

“We appreciate this opportunity to expand our relationship with ProLogis,” said Mark Morelli, President and CEO of UNI-SOLAR’s parent company, Energy Conversion Devices. ProLogis is a responsible corporate partner with UNI-SOLAR and has the vision for bringing more renewable energy right into the communities they serve around the globe.”

“This test site will provide a wealth of information about PV on rooftops and gives UNI-SOLAR the opportunity to showcase our unique, lightweight product. We believe these installations will provide clean, inexpensive energy to the power grid and also increase awareness of the benefits of solar energy as a top renewable energy source in North America and across the globe for generations to come.”

The Denver site totals 11 kWp DC of power generation capacity from 99 modules and eight different module manufacturers: Ascent Solar, First Solar, GS-Solar, MiaSole, Solyndra, Suniva, UNI-SOLAR and Xunlight. Already generating power, the initial configuration provides side-by-side comparisons of several module technologies, including monocrystalline, glass-on-glass thin film and membrane-applied thin film modules. In addition, the installation contains 16 individually monitored strings, each designed to test a certain system parameter.

Overall, ProLogis has solar projects installed or under construction on 32 buildings throughout France, Germany, Japan, Spain and the United States. The installations cover more than 10.6 million square feet (984,800 square meters) of roof space and total 24.6 MW.
