Sustainable Energy Partners with Tejados Industriales de Fotovoltaica to Deliver Breakthrough Technology to European Solar Markets

Barcelona, Spain – January 20, 2010 – Sustainable Energy Technologies Ltd (TSX V:”STG”) announced today that it has entered into an agreement with Tejados Industriales de Fotovoltaica, S.L. (“Tejados”), an engineering procurement and construction company focused on solar PV projects to supply Sustainable Energy’s next generation SUNERGY inverters totaling at least 10 MW in capacity for solar power projects in Spain and other European markets during 2010.

First deliveries under the Tejados contract are expected to begin during the latter part of the current fiscal Quarter. The next generation SUNERGY inverters are replacing Sustainable Energy’s successful first generation inverter, with first deliveries to European projects this month.

SUNERGY inverters enable the superior performance, intrinsic safety, and design flexibility of Sustainable Energy’s PARALEX system architecture that connects thin film solar modules in a massively parallel array.

"We are convinced that the PARALEX massively parallel system architecture using Sustainable Energy's SUNERGY inverters is by far the best solution for connection of thin film modules in the world today,” said Klaus Muller, CEO of Tejados.

“At Tejados, we are dedicated to bringing massively parallel thin film systems to our customers in all of our markets; and this agreement forms the cornerstone of what we see as a giant step forward for our business and for thin film solar in general. The performance advantages and ease of installation for thin film systems are far superior to anything else available and we look forward to a long and prosperous relationship with Sustainable Energy, added Muller"

Tejados is part of a network of solar PV engineering procurement and construction firms affiliated with Signet Solar GmbH and offering comprehensive solar power solutions throughout Europe. The Tejados decision to use the new SUNERGY inverters for its 2010 projects follows the installation of first generation SUNERGY inverters last year as part of a 1.8 MW solar PV project in the Czech Republic.

“We are very excited about our relationship with Tejados and its other partners in Europe,” said Robert Bucher President & CEO of Sustainable Energy. “Not only is this agreement an endorsement of the value of the SUNERGY technology and PARALEX massively parallel system architecture, but it is also a strong signal of the renewal of the Spanish solar PV market.”
