Sustainable Energy Technologies Ltd (TSX V:"STG") ("Sustainable Energy" or the "Company") Canada's solar inverter company, announced today that it has secured an operating line commitment for up to $1.5 million from a Canadian Chartered Bank to fund component purchases for production start up in Guelph in May, 2011.

Toronto, Ontario - March 16, 2011 - Sustainable Energy Technologies Ltd (TSX V:"STG") ("Sustainable Energy" or the "Company") Canada's solar inverter company, announced today that it has secured an operating line commitment for up to $1.5 million from a Canadian Chartered Bank to fund component purchases for production start up in Guelph in May, 2011.

Contributing to the need for capital is the Company's announced 23 MW supply agreement with tenKsolar (News Release dated March 16, 2011). The Company is currently selling products into the Ontario market and Europe from existing inventory, but must quickly increase production to meet growing demand for its SUNERGY inverters. Doughty Hanson has agreed to extend its previously announced standby equity agreement subject to specified conditions to March 1, 2012 as additional security for the operating line in exchange for which the Company will issue 4,848,484 common share purchase warrants exercisable for a period of one year at $0.165 per share.

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 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.
