After lagging behind the utility scale segment of the solar power renewable energy sector is really starting to take off in the US; it is is now on par with the commercial and residential segments in terms of market size and growing at a higher rate. This post summarizes AltaTerra Research’s newest report, “Utility Solar: U.S. Market Takes Off”.
A new study that is sure to create some controversy proposes that the world can provide for all of its energy needs, including electric, transportation, heating/cooling energy needs using only wind, water, and solar power by 2030.
Department of Energy (DOE) secretary Steven Chu announces $50 million in funding for solar energy grid parity demonstration program for innovative solar technologies leading to cost-competitive solar energy that helps solar reach this important milestone.
What is the variability problem of wind and solar energy, how serious of a problem is this and what can be done to fix it? This article examines this issue of variability, describing and defining it and listing some of the ways in which the unique challenges of wind and solar energy is being or can be addressed.
Suntech CEO, Zhengrong Shi, a prime mover in helping to turn China into a global force in photovoltaic technology, has been a major influence in bringing China’s solar PV cost structure down and making China a powerhouse in photovoltaic technology–and became a billionaire in the process. Shi’s ambition is to make solar power as cheap as conventional electricity.
Residential solar installations are fairly expensive propositions, making it more difficult for people to participate in this renewable energy resource. But now a relatively new concept—community solar—is seeing the light of day. Despite some financial, legal and technology barriers, a handful of utilities in cities like St. George, UT, and Seattle, WA, have come together for community solar, paving the way for more to follow. Private industry is also stepping in, helping the market to heat up more quickly.
Scientists at the California Institute of Technology have developed a new type of solar cell that comprise of arrays of thin silicon wires embedded in polymer substrate. The unique optical interactions between these wires provide the cells with an enhanced light absorption capability and improved internal quantum efficiency over conventional solar cells. These new cells are much cheaper to produce on account of the very low amounts of silicon needed to build them. The superior structural flexibility possessed by the silicon wire array solar cells is expected to further reduce their production cost since they can be produced using a lower-cost process.
It is a rough time to be a startup in the Solar Photovoltaic sector. The financial crisis and deep recession has not only dried up capital, but has also hit demand for solar panels, which has lead to a global supply glut and a price collapse. In this very difficult environment startups must compete with much larger established global suppliers that have factories of hundreds of megawatts each, an established customer base and well developed brand names and sales channels. In this post we look at five promising CIGS thin film Solar PV startups based in the US and try to catalog their unique strengths and accomplishments.
In this survey we are looking at the large US headquartered solar PV manufacturers with a view to examine how they are doing in this difficult economic climate. As basically anyone knows, who has not been cloistered away meditating in some cave, 2009 has been a very tough year for pretty much everyone.
