Sustainable Energy's ProFab Solar & Bilagot Energy to Deploy 20 ProFab Systems in Southwestern Ontario With Bilagot's Innovative Low Cost Mounting Technology

LONDON, ONTARIO--(Marketwire - May 14, 2012) - Sustainable Energy Technologies Ltd (TSX VENTURE:STG) ("Sustainable Energy" or the "Company") and Bilagot Energy ("Bilagot") jointly announced today that Bilagot (www.bilagotenergy.com) and ProFab Solar ("ProFab") (www.profabsolar.com) have agreed to deploy 20 ProFab systems throughout South Western Ontario using innovative ground based and rooftop mounting solutions developed Bilagot which will further reduce installation time and installation costs of the ProFab system.

Under a memorandum of understanding between ProFab and Bilagot, the initial 20 installations will be installed during the third Quarter of this year subject to usual regulatory approvals and conditional upon implementation of announced changes to the Ontario Feed in Tariff structure.

Based in Sarnia Ontario, Bilagot has co-developed renewable energy projects in Ontario, the Philippines, Australia, India, Poland, Hungary and Russia. The innovative mounting structures were developed under a Bilagot sponsored L910 initiative with technical support from the University of Western Ontario Research Park and industry partners with a view to driving costs from the balance of system costs in North America.

"We are very excited about our partnership with Bilagot which will continue ProFab's drive to deliver the lowest cost ground mount balance of system package for solar PV modules manufactured in Ontario," commented Livio Filice Director of Sales for ProFab Solar. This partnership will enable us to build on early success with the factory assembled system by further reducing installation time and cost and by expanding our distribution with Bilagot and their channel partners. "We look forward to rolling out the first 20 systems and expect to gain a significant amount of traction as Bilagot expands its distribution channels across Ontario through 2012 and beyond."

The two companies have agreed to explore opportunities to utilize the ProFab Solar kit in medium and large-scale FIT projects.
