Sustainable Energy Announces Multi-Megawatt Supply Agreement for US Market


Highlights:
• Sustainable to supply power electronics for tenKsolar's high efficiency rooftop solar PV system
• tenKsolar forecasting demand for 4,600 units (23MW) over first 12 months of agreement
• 8 MW minimum commitment (1,600 units) including deliveries to leading US distributors
• Collaboration to advance platform using Sustainable Energy's proprietary control technologies

Toronto, Ontario - March 16, 2011 - Sustainable Energy Technologies Ltd (TSX V:"STG") ("Sustainable Energy" or the "Company") announced today that tenKsolar will source its low voltage power electronics requirements for its integrated RAIS® Wave system from Sustainable Energy under a long term supply contract with the Company. tenKsolar's demand forecast for the first 12 months of the agreement beginning April 1, 2011 is an estimated 4,600 units or about 23 MW. tenKsolar has committed to a minimum of 1,600 units (8MW) over this period including units delivered through leading US distributors such as Stuart C. Irby Company.
The RAIS Wave system is a fully integrated non-penetrating integrated rooftop solution built around
RAIS smart solar modules that delivers AC energy directly off the rooftop. The system has been shown to provide between 25% and 100% greater energy density than conventional crystalline systems in many deployments. It can be installed at one of the lowest weights per square foot in the
industry.
The RAIS WAVE system integrates Sustainable Energy's patented low voltage inverter to deliver
maximum fire safety and high energy production while reducing cost and complexity by providing
everything needed for a commercial solar installation in one complete package.
As part of the agreement, Sustainable Energy has agreed to advance development of a product
platform for tenKsolar incorporating the Company's recently announced (News Release dated March 2,
2011) proprietary (patents pending) control technologies, with tenKsolar contributing to non-recurring
engineering costs associated with development.
tenKsolar's RAIS systems will be sold principally in the US for commercial and institutional solar
rooftop applications.
For competitive and customer confidentiality reasons, the Company does not disclose the value of
specific supply contracts unless required to do so by agreement or law. Product pricing will typically
reflect market pricing unless otherwise noted.
About tenKsolar Headquartered in Minneapolis, Minnesota, tenKsolar designs, manufactures and
markets the world's most productive and reliable photovoltaic solutions. The tenKsolar RAIS® Wave
system combines RAIS PV modules, RAIS Wave Light-Smart reflectors and integrated racking into a
repeating wave pattern yielding the highest energy density output for flat roof or ground mount
systems. In addition, multiple levels of failover redundancy within the system ensure the greatest
lifetime energy output.
tenKsolar's proprietary Cell Optimizing architecture makes the tenKsolar RAIS PV modules more
efficient and unique in their ability to generate energy from all available light, whether direct, diffuse
or reflected. By designing the RAIS PV module and its proprietary filtering reflector as structural
components in the RAIS Wave, tenKsolar developed a minimal ballasting, easy-to-install, low-cost
system which requires no roof penetrations.
About Sustainable Energy:
Sustainable Energy (www.sustainableenergy.com) is Canada's solar inverter company. The
Company's patented inverter technologies are a breakthrough in advanced power electronics 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.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
