Entech Solar, Inc. develops innovative, patented solar technologies, including concentrating photovoltaic (CPV) systems for both ground and space power applications and sustainable daylighting solutions for the commercial, industrial and utility markets. Entech Solar designs concentrating solar modules that produce electricity from sunlight as part of the SolarVolt™ product line. The Company also manufactures and markets the Entech® Collimating Skylight, a state-of-the-art skylight that provides superior light output and optical efficiency for the commercial and industrial “green” building markets. The Entech Solar will exhibit its unique skylight technology at LightFair International in Philadelphia May 17-19, 2011.
Entech Solar has keen interest and working actively to develop several new daylighting products for illuminating commercial, industrial, and institutional buildings with natural sunlight. The Latest Developments in Entech® Solar’s Daylighting Products are cleared in first phase of testing stage for its two products, and now, Entech Solar is using this opportunity to share the exciting results. These products are based on Entech Solar’s patented collimating skylight technology that redirects the solar rays to the working area beneath the skylight, and thereby provides significant improvements over conventional skylights in both the quantity and quality of the light delivered to the working space. The two new products are a high-lumen-output collimating skylight and a collimating add-on kit for skylights produced by others. The key test results for these two new products are as below.
High-Lumen-Output Collimating Skylights - Over the past three weeks near spring equinox, Entech Solar has on clear days consistently measured over 50,000 lumens of peak output near solar noon for a new collimating skylight with an above-roof window aperture area of only 6.2 square feet. Since the equinoxes (spring and fall) are representative of the “average” sun angles for the whole year, it is percipient that these results characterize the “average” peak lumen output for all the clear days of the whole year. This new high-lumen-output collimating skylight also uses very cost-effective materials and construction techniques.
It is expected that this new product commercially available during the second quarter of this year at very attractive prices per lumen of daylight delivered. Entech Solar also planning to offer an even larger unit for “big box” retail stores, warehouses, and factories. These larger units can provide over 100,000 lumens of peak output originating from only 13 square feet of above-roof window aperture area.
Collimating Add-On Kits for Skylights Made by Others - The first “add-on kit” collimator of Entech Solar, for improving the day lighting performance of skylights made by others, are also tested by Entech Solar over the past few weeks. This add-on collimator eliminates the glare from conventional skylights and directs the lumen output to the workspace below the skylight, where it is needed. Entech Solar’s first test unit was attached to an Apollo® Light Pipe made by Orion Energy Systems, whose plant is in Manitowoc, Wisconsin. The Entech Solar’s measurements during March 2011 have verified that these collimator add-on kit eliminates glare and dramatically improves the delivery of usable lumens to the workspace below the skylight. Near solar noon, the improvement was about 60%. In mid-morning or mid-afternoon, the improvement was about 100%. In early morning or late afternoon, the improvement was about 130%. On average throughout the day, the collimator eliminated glare and essentially doubled the usable lumen output delivered to the workspace below the skylight. Entech Solar also planning to offer performance enhancing add-on collimator kits for other types of conventional skylights made by other companies.
