Alliant Energy is seeking to expand its renewable energy generation with solar power. Alliant Energy's Iowa utility is issuing a request for proposals for new solar projects that could increase its system-wide solar generation by 50 percent.
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.
A team of students at Missouri University of Science and Technology spent two years designing and building a solar-powered house filled with smart-living technology. Once it was complete, the students cut it into pieces and shipped it to California on four semitrailers to compete in an international building competition.
Scientists at Brunel University London have designed a new hybrid roofing system which could halve energy bills in new homes.
Yingli Green Energy Holding Company Limited, one of the world's leading solar panel manufacturers, today announced that it recently signed several agreements with Qingdao New Energy Solutions Inc. (NESI), a leading provider of agricultural and industrial building-integrated photovoltaic (BIPV) and utility-scale solar solutions, for the supply of 130 megawatts (MW) of high quality solar panels. Yingli has begun to deliver the first 30 MW and expects to complete the delivery by the end of September 2015.
AEP Energy, a subsidiary of American Electric Power, has partnered with the City of Clyde, Ohio, to design, build, own and operate a 3.6-megawatt solar energy array.
SolarWorld– the largest U.S. crystalline silicon solar manufacturer for 40 years, with well over 1 gigawatts of annual production capacity to its name – announced today that the company and Panasonic Enterprise Solutions Co., a division of Panasonic Corp. of North America, have signed an agreement for SolarWorld to supply 65 megawatts of the company’s high-efficiency, 72-cell solar panels for a solar farm planned in remote southeast Oregon. The contract, to be fulfilled in 2016, encompasses the largest single project supply in the company’s history.
At a dedication event in Coconino County today, SunEdison, Inc., the largest global renewable energy development company, celebrated the commissioning of 1.2 megawatts (MW) DC of solar carport and rooftop systems at four Coconino County, Ariz., government facilities. The buildings include the county's King Street Community Services building, law enforcement administration facility, juvenile detention center and correctional facility.
Much of the nation's energy policy is premised on the assumption that clean renewable sources like wind and solar will require huge quantities of storage before they can make a significant dent in the greenhouse gas emissions from electricity generation.
An analysis carried out by JRC scientists shows that the uncertainty in measurement of power generation from a photovoltaic (PV) cell can be more than halved, thus bringing an economic benefit to both manufacturers and investors.
