Sustainable Energy Introduces PARALEX Solar Power System to North American Market

PARALEX first to deliver safety of extra low operating voltages for rooftop applications with world class conversion efficiencies

ANAHEIM, CALIFORNIA--(Marketwire - Oct. 27, 2009) - Solar Power International Conference, Sustainable Energy Technologies Ltd (TSX VENTURE:STG) ("Sustainable Energy") today introduced PARALEXTM, a unique extra low voltage, high yield commercial rooftop solar power system to the North American market.

PARALEX changes the game for the rooftop solar power industry by delivering a greater return on investment while providing the highest level of safety and reliability for building owners, suppliers, integrators and contractors. Key benefits include:

  • Increased power yields—PARALEX produces 5-15% higher energy yields per kilowatt installed in comparison to conventional systems.
  • Highest level of safety—PARALEX has an inherently safe, extra low voltage design that addresses concerns of public safety and liability critical for commercial and public buildings
  • Lowest cost of ownership— PARALEX has a simple, flexible design that requires no special integrators, system designers or installers, reducing the cost of installation and maintenance. The result is the lowest cost per kilowatt hour for maximum return on invested capital.

"PARALEX raises the bar for solar power systems providing public sector and commercial building owners an efficient, sustainable energy source while delivering the maximum return on investment," said Robert Bucher, President and CEO of Sustainable Energy. "The performance benchmark results demonstrate the increased system energy yield PARALEX delivers by turning each thin film module into an independent solar power generator. With the introduction of PARALEX, Sustainable Energy is poised to capture rooftop solar market share by accelerating the acceptance of thin-film products and reducing the time and complexity of installations."

PARALEX combines Sustainable Energy's proprietary extra low voltage inverter, SUNERGY, with standard thin film PV modules in a parallel architecture that maximizes energy yield, simplifies installation, and reduces total system cost, while addressing safety concerns associated with high voltage products. Unlike traditional series string architecture power systems that reduce system power output to the level of the lowest producing panel, PARALEX connects solar modules in parallel, ensuring that each individual module performs at its maximum potential. Additionally, PARALEX reduces the impact of shading, soiling, and other real world factors without the need to add complex module micro inverter electronics that increase installation and maintenance costs or traditional high power inverters that require complex shading analysis and decrease total power delivery.

PARALEX stands alone in meeting the emerging safety concerns for commercial and public sector facilities such as schools, shopping centers, office complexes and recreational areas. PARALEX operates at consumer appliance voltage levels from 50 – 150v compared to high voltage systems that operate at levels up to 1000v. The elimination of high DC array voltages provides an important safety benefit to installation and maintenance crews. In addition, the SUNERGY inverter products utilize low voltage electrical components increasing long-term reliability while decreasing manufacturing costs.

About Sustainable Energy: Sustainable Energy ( is changing the way the world installs solar power through PARALEX a unique line of solar energy products and systems for commercial and public sector markets. PARALEX is based on a patented extra low voltage high yield inverter, with both crystalline and thin film PV modules, which enables a parallel architecture to increase total system yields while also addressing emerging safety concerns. PARALEX achieves higher energy yields and operates at intrinsically safe voltages as well as enabling simpler more flexible design that improves module coverage of any rooftop. The result is the lowest cost per kilowatt hour for maximum return on invested capital.

Sustainable Energy's technologies are the subject of multiple patents issued by the US Patent Office with further patents pending.
