Sustainable Energy Announces SUNERGY(TM) Accelerated Life Testing Results

TORONTO, ONTARIO, Dec 3, 2010 (Marketwire via COMTEX News Network) --

Sustainable Energy Technologies Ltd (TSX VENTURE:STG) ("Sustainable Energy") Canada's solar inverter company, is pleased to announce that independently conducted highly accelerated life testing ("HALT") has confirmed the exceptional reliability of the Company's SUNERGY platform enabling the Company to confidently extend its product warranty to a standard 10 years and to offer customers an optional 20 year extended coverage.

HALT is an industry standard test procedure that uses a series of individual and multiple simultaneous stresses such as multi-axis vibration, temperature cycling and product power cycling to identify any latent design defects as well as stressing the product to operational limits in order to assess design robustness and marginality. The SUNERGY(TM) inverter exceeded expectations at every phase of testing and no product weakness was identified, including during operations that were well beyond specified the inverter's operating limits of minus 40 degrees C to plus 50 degrees C.

"The exceptionally good test results reflect the design simplicity and robust character of the SUNERGY platform," said Brent Harris, Chief Technology Officer of Sustainable Energy. "The power electronics circuits have remained substantially unchanged for several years and we have successful operating experience with more than 10MW of installations in Europe, the majority of which have been in the field for almost three years."

Sustainable Energy will showcase its next generation SUNERGY(TM) inverters at Solar Canada 2010, booth #904. Solar Canada is Canada's largest solar industry exhibition and conference, hosted by the Canadian Solar Industry Association December 6-7, 2010 at the Metro Toronto Convention Center.

SUNERGY (TM) inverters can be purchased directly from Sustainable Energy, or through its growing network of distributors in Canada and the USA. Interested parties can contact the North American sales team at 1.647.258.0343.

About Sustainable Energy:

Sustainable Energy (www.sustainableenergy.com) is Canada's solar inverter company. The Company's patented inverter technologies are a breakthrough in power inverter design and capabilities for all forms of distributed generation and smart grid applications.

The SUNERGY(TM) inverter is the industry's only grid-interactive solar inverter which enables a "parallel" solar PV system architecture in higher power ratings at a cost and serviceability factor that is comparable to conventional inverters in the market. The benefits of parallel solar are: (i) 5% - 25% higher total system power output; (ii) a better fill factor enabling better coverage of available space; (iii) simplified system design and installation; and (iv) the safety of extra low operating voltages which ensures the safety of building maintenance personnel, first responders, and tradesmen who may accidentally come into contact with system wiring.

Sustainable Energy's technologies are the subject of multiple patents issued by and pending with the Canadian and US Patent Offices.
