Carlisle Energy Services and Energy Conversion Devices to Deliver Photovoltaic Systems for Commercial Roofs

CARLISLE, Penn. - January 30, 2009 - Carlisle Energy Services, a newly formed division of Carlisle Construction Materials and a leading manufacturer of energy-efficient single-ply roofing systems, and Energy Conversion Devices, Inc. (NASDAQ: ENER) (ECD), a manufacturer of proprietary, thin-film amorphous silicon-based photovoltaic (PV) laminates announced that they have reached a multi-year agreement for ECD to supply its UNI-SOLAR laminates to Carlisle Energy Services.

According to John Altmeyer, CEO of Carlisle Construction Materials, "UNI-SOLAR products are a natural fit for both our EPDM and TPO single-ply roof systems and our extensive network of certified installers, as they can be readily adhered to the rooftop without the need for special equipment. Furthermore, these products contain no glass, operate in low-light situations and offer excellent performance in high temperatures, allowing Carlisle to offer an ideal solution for regions where traditional rooftop PV systems have been prohibited or excluded due to inclement climatic conditions."

"As an expert in rooftops and roofing, Carlisle is an excellent new partner for Uni-Solar in the United States. We believe the United States marketplace has excellent growth potential, and we look forward to growing our US business with Carlisle as we continue to grow our position as the leader in rooftop and building integrated PV products," said Mark Morelli, president and CEO of Energy Conversion Devices.

At less than one pound per square foot, UNI-SOLAR laminates arelightweight and non-intrusive and require no rooftop penetrations or mounting systems, eliminating the negative impact on roof life and performance that is associated with penetrating PV systems. Additionally, these thin-film PV laminates provide a solid return on investment through a low installed cost and low cost-per-kilowatt-hour of energy produced when compared to traditional rigid glass panel PV alternatives.

Carlisle Energy Services will offer a number of services in conjunction with the sales and distribution of its PV products, including: complete system design and monitoring, 20-year single-source warranty on all system components and comprehensive service options throughout the life of the system.
