Low-cost 'solar absorber' promising for future power plants

Emil Venere for Phys.org: Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might run up to 24 hours a day.

The Growing Importance of Global-scale Renewable Energy

IEC provides a framework to test and certify renewable energy technology.

The World's Biggest Solar Energy Storage Farm Is Set to Launch in Australia

David Nield for Science Alert: Construction will soon be underway on a gigantic solar farm in South Australia that's set to be the biggest of its kind in the world - thanks to 3.4 million solar panels and 1.1 million individual batteries. The project is expected to be completed by the end of the year, at which point the huge plant should outdo all other solar farms in terms of overall battery capacity - although other solar facilities are larger in terms of land area.

NREL Publishes Landmark Residential Solar PV + Energy Storage Cost Breakdown

Joshua S Hill for CleanTechnica: The US National Renewable Energy Laboratory has published a landmark report extensively detailing component and system-level cost breakdowns for residential PV solar systems equipped with energy storage. The decreasing cost of solar systems has been well documented over the last several years, with increased innovation and decreasing manufacturing costs combining to make solar PV a competitive and economic choice for residents and utilities across the United States, and in fact the world. As such, the costs attributed to the development of residential and utility-scale solar projects has been well defined for some time - even though that figure keeps decreasing.

Wind Energy Now Directly Competing With Coal On Cost

Gregory Brew for OilPrice.com: Last week, Xcel Energy announced a multi-state wind capacity project, anticipated to be the largest in the United States. Spanning seven states, the project covers eleven new wind farms and would generate 3280 MWs at a cost of $3.5-4.4 billion. In its announcement, Xcel emphasized the cost-savings attached to wind power, arguing that it would save Xcel customers in the Midwest $7.9 billion over thirty years. This, rather than the environmental benefits of renewable energy, drove the company's mission statement: wind was cheap, not just clean.

Fla. movin' on up with solar power

NWFDailyNews: For years, Florida has been an underachiever in solar power. Despite being ranked third in the nation for rooftop-solar potential by the Solar Energy Industries Association, Florida annually has finished in the high-teens for actual installations. But the Sunshine State's solar prospects are beginning to brighten - and the results are making an economic impact.

Tata Power Solar Expands and Modernises its Manufacturing Facility

The two-stage expansion doubled the company's module capacity to 400 from 200 MW, and increased its cell manufacturing capacity by 65 per cent from 180 to 300 MW.

Solar Energy DealReader: Q4 2016

Consolidation amongst producers as well as private equity and private investment in solar largely drove demand for solar deals.

Big Oil Replaces Rigs With Wind Turbines

Jess Shankleman for Bloomberg: Big oil is starting to challenge the biggest utilities in the race to erect wind turbines at sea.

Record-breaking solar panel converts more than a quarter of sunlight into electricity

Ian Johnson for Independent: A record-breaking solar panel that can convert more than a quarter of the sunlight it receives into electricity has been developed by researchers in Japan.

Tracking the Sun - A Growing Opportunity

Tracking is still relatively young -- the majority of deployments have really been in just the past few years -- but it's growing up fast.

Trump Should Make Space-Based Solar Power A National Priority

Space-based solar power (SBSP) --- in which satellites in Earth orbit capture the Sun's radiation, convert it to electricity and then transmit it back to Earth in the form of either microwaves or lasers --- would arguably do more to positively impact the lives of everyday Americans and fellow citizens of the world than almost anything the new President could champion.

The Economics of Small Commercial Solar Projects

Solar projects can be a great investment for many businesses and offer a solid ROI, but it takes time and energy to put together a project that works for all the interested parties-the customer, the bank, and the installer.

Google: 4 out of 5 US homes have solar power potential

Steve Dent for engadget: A five kilowatt rooftop solar installation now costs just $12,500 on average after tax credits, and pretty soon, installing one might soon be a matter of re-tiling your roof. Whether it's right for you, however, depends in large part on how much sun your house gets. That's where Google's Project Sunroof comes in -- launched just two years ago, it has now surveyed over 60 million US buildings in 50 states. That means there's a good chance you can see the electricity production potential in your city, neighborhood and even specific house. Google calculates the amount of sunlight on your roof based on "3D modeling of your roof and nearby trees," weather patterns, the position of the sun in the sky during the year and shade from buildings, trees and other obstructions. That info is then converted to energy production "using industry standard models for solar installation performance," Google says. Cont'd...

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
