High Profile 50kW Industrial Rooftop FIT Project in Ontario Selects SUNERGY inverters

Toronto Ontario - November 4, 2010 - Sustainable Energy Technologies Ltd (TSX V:"STG") ("Sustainable Energy" or the "Company") Canada's solar inverter company announced today that it has been chosen as the inverter technology to be used in a high profile 50kW installation from a leading EPC and project development company based in Southern Ontario. The SUNERGY inverters will be installed on an industrial rooftop owned and operated by one of the largest automotive suppliers in Canada.


"We are excited to be securing projects like this which demonstrate the value of parallel with the
SUNERGY inverters in one of the highest profile installations in Ontario" said Axel Hartung, Chief Sales & Marketing Officer for Sustainable Energy. "With our sales book full for the balance of 2010, our sales team is beginning to aggressively secure business for calendar Q1-Q2 2011."

"The value of parallel systems is gaining traction in the Ontario market and we are emerging as the "go to" solution for larger installations looking to optimize power output and return on investment at a cost and serviceability factor that is needed for these applications," added Hartung.

The SUNERGY inverters are expected to be shipped in November 2010 with grid connection to follow shortly thereafter. Details on the projects are expected to be made public before the end of this year.

For competitive and customer confidentiality reasons, the Company does not disclose the value of the contracts or the customer.

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
SUNERGYTM inverter is the industry's only grid-interactive solar inverter which enables a "parallel"
solar PV system architecture 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 US and International Patent Offices
