Luminus facility goes 100% green


The firm’s Woburn, Massachusetts facility has purchased wind power RECs from Constellation Energy


Luminus Devices, the innovator of “Big Chip LEDs”, has entered into a contract with Constellation Energy to purchase Renewable Energy Certificates (RECs) to match 100% of its electricity use at the Woburn, MA facility from October 2011 through October 2012.


The RECs supplied by Constellation Energy are Green-e Energy Certified and sourced from wind energy facilities located throughout the United States. Throughout the term of the contract, 100% of the electricity at Woburn will be matched with RECs.


Each REC represents the positive environmental attributes of 1 megawatt hour (MWh) of electricity generated by a renewable power plant, and is retired on behalf of customers wishing to promote their environmental commitment. Through the purchase of RECs, Luminus and Constellation Energy are supporting the operation and development of facilities that generate clean, renewable energy.


Jim Gallo, facility manager at the Luminus Woburn operation, commented, “Our LED products are highly energy efficient, and this purchase of Renewable Energy Certificates improves the sustainability of our manufacturing processes. We are pleased to take advantage of this opportunity with our energy supplier.” Woburn annual electricity consumption for wafer fabrication is approximately 2,000,000 KWh; with the purchase of RECs Luminus helps avoid 946 metric tons of CO2 emissions.


First and only fully Integrated commercial solar system


The system incorporates triple-junction, III-V compound semiconductor cells and is claimed to reduce costs in all stages of the project lifecycle


GreenVolts has unveiled what it says is the industry’s first complete and fully integrated solar system, including modules, trackers, inverters, and energy management software. Through control of the entire system design, GreenVolts says it has dramatically improved performance, simplified project engineering and installation, and reduced costs in all stageof the project lifecycle

“Our complete system approach changes the entire solar experience,” said David Gudmundson, president and CEO, GreenVolts. “With GreenVolts, customers get simplicity, elegance, and precision in a utility-scale solar system that delivers higher performance and richer energy management than anything else in the world.”


Traditional photovoltaic (PV) systems are composed of parts sourced from different suppliers, including solar panels, inverters, trackers, and monitoring. Because these parts are not designed to work specifically with one another, the overall system performance suffers. In contrast, GreenVolts provides a complete and fully integrated solar system, with
