Low-cost wafers for solar cells
2015-10-12 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Silicon wafers are the heart of solar cells. However, manufacturing them is not cheap. Over 50 percent of the pure silicon used is machined into dust. A new manufacturing technique developed by Fraunhofer researchers puts an end to these material losses, with raw material savings of 50 percent along with an 80 percent reduction in energy costs. They sparkle in dark blue on the rooftops. In our homes they give us illumination, while providing lamps, refrigerators and other household appliances with...

Solar Bypass Device offers surge protection for PV solutions.
2015-10-12 14:31:07| Industrial Newsroom - All News for Today
Equipped with CoolRUN™ technology, LX2410A IDEAL™ provides bypass path in PV module applications. Active bi-directional device handles up to 500 A of surge protection in forward and reverse direction. CoolRUN technology's non-hiccup control eliminates EMI radiating from PV module strings. Measuring 0.7 mm thick, product replaces Schottky diodes in junction boxes with under-the-glass solution. Pads are 2.6 mm apart to meet IEC61730-1 and IEC61730-2 creepage and clearance requirements.

China raises solar installation target for 2015
2015-10-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: China has raised its solar power installation target for 2015 by 30 percent from its previous goal, state media reported, potentially adding to overcapacity as insufficient grid capacity remains a hurdle for the new plants to deliver power. Solar plants can in theory delivery returns of 10-15 percent under long-term power purchase contracts with state utilities but in practice face problems of subsidy collection and panel quality, making investors wary of the sector. China will add another...
