This year will be a solar-powered Super Bowl

By Jeff Clabaugh for WTOP:  Levi’s Stadium in Santa Clara, California, will set the stage for Sunday’s Super Bowl, and it will be a solar-powered event. Levi’s Stadium, which opened in July 2014, is the first professional football stadium in the NFL to open with LEED Gold certification, according to the Solar Energy Industries Association in Washington. Princeton, New Jersey-based NGR Solar LLC installed more than 1,150 solar panels at the stadium during its construction — enough to produce 375 kilowatts of peak power. The system can generate enough power in a year to meet electricity demand during every San Francisco 49ers home game. The solar panels cover three bridges that connect the stadium to the main parking lot and the “NRG Solar Terrace” that overlooks the field. There are 544 solar panels on the stadium roof and another 642 on the bridges, which also serve as canopies covering the bridges.   Cont'd...

Net Metering - Doing it Right

Companies selling PV systems are concerned that if utilities add a set fee for solar customers to remain connected to the grid to take in electricity at times when the sun isn't shining, or if utilities decrease the retail credit for the times when customers send their excess generation back to the grid, people will be less likely to put panels on their roofs.

France to pave 1000km of roads with solar panels

Derek Markham for TreeHugger :  Over the next five years, France will install some 621 miles (1,000km) of solar roadway using Colas' Wattway solar pavement. Solar freakin' roadways! No, this is not the crowdfunded solar road project that blew up the internet a few years ago, but is a collaboration between Colas, a transport infrastructure company, and INES (France's National Institute for Solar Energy), and sanctioned by France's Agency of Environment and Energy Management, which promises to bring solar power to hundreds of miles of roads in the country over the next five years. One major difference between this solar freakin' roadway and that other solar freakin' roadway is that the new Wattway system doesn't replace the road itself or require removal of road surfaces, but instead is designed to be glued onto the top of existing pavement. The Wattway system is also built in layers of materials "that ensure resistance and tire grip," and is just 7 mm thick, which is radically different from that other design that uses thick glass panels (and which is also claimed to include LED lights and 'smart' technology, which increases the complexity and cost of the moose-friendly solar tiles).   Cont'd...

California narrowly upholds critical solar policy

NICHOLA GROOM for Reuters:  California, which boasts more than half of the households with solar panels in the United States, on Thursday extended a policy that has underpinned the rooftop solar industry's dramatic growth over the last decade. The 3-to-2 decision by California's Public Utilities Commission at a meeting in San Francisco to extend net metering was a major victory for the solar industry, including companies like SolarCity Corp, Sunrun and SunPower Corp. Net metering allows homeowners with solar panels to sell the power they generate but don't use back to their utility at the full retail rate, sometimes giving them a credit on their bill at the end of the month. The 20-year policy has been critical to making solar cost competitive. But the narrow victory underscored palpable frustrations with the policy, which has been criticized for rewarding solar users while leaving other ratepayers to shoulder the cost of maintaining the electricity grid. "I will be the first to say that I think we really have a ways to go before we have a really enduring rooftop strategy," said PUC President Michael Picker, who voted in favor of extending the policy. The PUC will reconsider net metering again in 2019.   Cont'd...

1.2-million sq. ft. solar panel 'Gigafactory' in Buffalo almost ready, will make 1 GW/year

Michael Graham Richard for TreeHugger:  Soon after SolarCity acquired solar panel maker Silevo in the summer of 2014, it announced the construction of a 1.2-million-square-foot 'Solar Gigafactory' in Buffalo, New York. The move had two main goals: 1) For the solar installer to get its own secure supply of high-efficiency solar panels (Silevo panels are currently 21% efficient, but the company claims that they can get to 24%) and 2) drive down the cost of the panels and of installing them. If the panels are higher efficiency, you need fewer of them per roof for a given capacity, lowering installation costs, and if you make them in very large quantities in a 'Gigafactory', you can further reduce costs through economies of scale. The Buffalo solar gigafactory, which can be seen in the photo at the top of this article, aims to start producing solar cells in 2016, with a ramping up to 1 GW of annual capacity by 2017. If all goes well, the facility could eventually be expanded to 5 GW/year at some point. The solar cells produced there have a target price of around $0.50/watt, which would make them very competitive with other power sources.   Cont'd...  

The Two Things To Note In The DOE's Solar + Storage Initiative

Michael Kanellos  for Forbes:   The Department of Energy doled out $18 million in grants this week as part of an effort to drive down the cost of solar plus storage down to less than 14 cents a kilowatt hour. The DOE, under its SunShot program, has long had a goal of driving down the cost of solar alone to 6 cents per kWh by 2020.  So far, the program has hit its milestones. Grants recipients include Austin Energy, Carnegie Mellon University, the Electric Power Research Institute (EPRI) and Aquion Energy, among others. The DOE regularly gives out grants, but the latest program is somewhat interesting because: First, that’s a really low price for storage. Utility-scale solar, generally cheaper than residential solar, without storage delivered power for 14 cents a kilowatt hour in 2014. The cost of batteries, however, has been declining rapidly. Ten years ago, batteries progressed slowly compared to other electronic devices: Tesla Motors TSLA +0.50% co-founder and CTO J.B. Straubel was famous for noting that the performance of batteries doubled every decade, versus the roughly two year cycle for semiconductor.   Cont'd...

A solar-powered soccer pitch in Lagos also uses players' footfall to keep the lights on

Yomi Kazeem for Quartz:  Africa is already waking up to the possibilities that renewable energy provides, the African Union has pledged a $20 billion investment over the next decade. In East Africa, pay-as-you-go solar energy services arealready proving a mainstream success. In West Africa, things are still at an early experimental stage. One such experiment is a solar-powered football pitch which also uses kinetic energy generated by footballers playing. Located at a teacher’s college in Lagos, Nigeria’s commercial center, the innovative soccer pitch was launched last year in a three-way collaboration between energy giant Shell; music star Akon, who has been championing solar energy on the continent; and Pavegen, a UK-based start-up which has a target of providing low-cost renewable energy solutions to Africa’s electricity problems. Perhaps the most interesting technological feature of the solar-powered pitch—only the second ever launched across the world (the first was launched in Brazil in 2014)—is that it combines both kinetic and solar energy to produce electricity.   Cont'd...

Juno spacecraft breaks solar power distance record

Jim Sharkey for SpaceFlight Insider:  NASA’s Juno mission has broken the record for distance traveled by a solar-powered spacecraft. Juno reached this milestone at 11 a.m. PST (2 p.m. EST) on Wednesday, Jan. 13, when the spacecraft was approximately 493 million miles (793 million kilometers) from the Sun. The record was previously held by the European Space Agency’s (ESA)  Rosetta spacecraft, whose orbit peaked at the 492 million-mile (792-million kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko. “Juno is all about pushing the edge of technology to help us learn about our origins,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. “We use every known technique to see through Jupiter’s clouds and reveal the secrets Jupiter holds of our solar system’s early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it.” Juno is the first solar-powered spacecraft designed to operate so far from the Sun. Generating sufficient power to operate the spacecraft requires a very large area of solar cells. The four-ton Juno spacecraft carries three 30-foot (9-meter) solar arrays festooned with 18,686 individual solar cells. At Earth’s distance from the Sun, the cells can generate about 14 kilowatts of electric. The further away from the sun the spacecraft is, the lower the power its solar cell will be able to generate.   Cont'd...
