To understand how the energy storage in the United States – particularly California — is heating up, just follow the money. Green Charge Networks, a Silicon Valley storage installer, announced Tuesday that it has lined up a $10 million fund from TIP Capital to finance projects. Green Charge installs lithium-ion batteries for businesses, who could forgo owning the storage equipment and pay for energy storage as a service via a long-term contract instead. “Energy storage is what a lot of clean energy financing companies are working toward,” said Vic Shao, CEO of Green Charge Networks, which was founded in 2009. “Everybody realizes that this is what’s coming and they need to get on board.” This leasing model has succeeded in expanding rooftop solar panel installations at homes and businesses, which could use solar electricity without paying tens of thousands of dollars upfront to own the equipment. Installers often market solar electricity as being cheaper than the electricity from utilities, though that saving usually isn’t guaranteed for the duration of the contract. Storage installers tend to pitch their services to businesses and government agencies that want to reduce the so-called “demand charge.” A utility collects the fee to help pay for its readiness to generate and send power to meet its customers need, especially when demand is high.

Trina Solar a global leader in photovoltaic modules, solutions and services, announced today that researchers from Trina Solar and the Australian National University have jointly developed a new high-efficiency solar cell. The laboratory scale Interdigitated Back Contact cell was developed at the Australian National University Centre for Sustainable Energy Systems under a research and development contract with Trina Solar through a collaboration contract with the Solar Energy Research Institute of Singapore. After two years of research, funded by Trina Solar, the ANU has developed, with contribution from Australian consulting firm PV Lighthouse, an IBC silicon solar cell, which was independently tested by the Fraunhofer CalLab in Germany to be able to deliver an efficiency of 24.4%, putting it among the most efficient solar cells to date. Trina Solar is now developing a commercial version of the IBC solar cell as well as an IBC PV module. The commercial cell has already reached an efficiency greater than 22% for a 125mm by 125mm IBC solar cell, and 238W for an IBC PV module (based on 72 cells), which was independently tested by the National Center of Supervision and Inspection on Solar Photovoltaic Products Quality of China. Though it is currently in laboratory scale, the new solar cell will soon be ready for industrialized mass production.
Tesla's grand expansion plans will be funded in part by raising $1.6 billion through a bond issue that the automaker announced Wednesday. The money will be used to build what its founder Elon Musk has dubbed the "Gigafactory" and for production of a more affordable, new mass market vehicle. The massive factory is expected to produce more lithium ion batteries annually by 2020 than were produced worldwide in 2013. Those batteries, and the reduction in their cost, are vital to Tesla's ability to produce a cheaper car in numbers that could catapult the company into the ranks of the major automakers. The electric car maker's current model, the Tesla S, has a starting price of $69,000 and can go more than 200 miles between charges. The new factory, expected to cost $4 billion to $5 billion, could be located in either Arizona, Nevada, New Mexico or Texas, the company said Wednesday. It could take up between 500 and 1,000 acres, employ about 6,500 people, and produce batteries needed for about 500,000 cars per year, Tesla said. Tesla recently increased its sales forecast for 2014, saying it expects global sales to reach 35,000 vehicles. Construction expected to start later this year and production at the plant due to begin in early 2017.
Germany-based SMA Solar is to acquire Danfoss’ solar inverter business. Danfoss will acquire 20% of SMA’s shares with a value of €302 million (US$415 million) in return for selling its inverter unit. It will receive SMA shares at a price of €43.57 50% premium on the average price during (US$59.86) the past 60 days. The alliance between SMA and Danfoss brings together respectively the world's largest and seventh largest inverter manufacturers by market share, according to an IHS study published in May. “The strategic alliance with Danfoss strengthens SMA’s leading position in the global photovoltaic market. We are faced with a highly competitive market environment and increased price pressure,” said Pierre-Pascal Urbon, chief executive of SMA. “In this context, SMA will benefit from Danfoss’ years of experience in automated drives. This market has been characterised by fierce competition for a long time. Accordingly, the strategy of the Danfoss group targets continuous cost improvements through global sourcing and cost down initiatives. By establishing a close cooperation there is significant potential to improve the cost position in both companies,” added Urbon The inverter market has been hit by the emergence of bigger utility projects that require larger but fewer inverters, and the rise of new players in the microinverter market that have stolen share in the residential sector.
The nation’s first offshore wind farm on the Pacific Coast cleared a crucial federal hurdle after Seattle’s Principle Power received approval to move forward on a commercial lease for the proposed $200 million, 30-megawatt project. Principle Power received the go-ahead this month from a Department of the Interior agency to lease 15 square miles of federal waters, 18 miles from Coos Bay, Ore. If the lease request gets final approval, the WindFloat Pacific project would anchor the first offshore turbines in federal waters on the West Coast. It also would be the first in the nation to use triangular floating platforms instead of single piles driven into the ocean floor. At this stage of the complicated federal process, Principle’s plan is considered a demonstration project. DOI’s Bureau of Ocean Energy Management (BOEM) released a finding that there are “no competitive interests for the offshore area of Oregon” where the company has requested the commercial lease. That finding clears the way under BOEM’s non-competitive leasing process for Principle Power to submit an implementation plan for the project. WindFloat Pacific will demonstrate floating offshore wind technology; it is one of the Department of Energy’s (DOE) seven Offshore Wind Advanced Technology Demonstration Projects.
Tesla Motors' CEO Elon Musk says that this week, he will detail his plans to build a huge plant to make electric car batteries — so big that he calls it the "gigafactory." Compared with Tesla's swoopy electric luxury cars, making lithium-ion battery packs sounds decidedly unsexy. But Tesla apparently views the plant as critical to its strategy. Reasons: •Steady supply. Tesla will make the case that it needs its own source of battery packs. It has made no secret of its inability to get enough batteries through its deal with Panasonic to keep up with demand for its Model S electric sedan. It says the current shortage will last through the first half of the year. •Other revenue streams. The plant could supply batteries to other carmakers and for other uses. Musk also is chairman of SolarCity, which has announced plans to sell Tesla battery packs to companies to use for emergency backup power storage. •Future models. Tesla is developing a more mainstream electric car for sale in several years. But it will need to dramatically lower battery costs and increase supply to create a mass-market vehicle.
SUNLIGHT is free, but that is no reason to waste it. Yet even the best silicon solar cells—by far the most common sort—convert only a quarter of the light that falls on them. Silicon has the merit of being cheap: manufacturing improvements have brought its price to a point where it is snapping at the heels of fossil fuels. But many scientists would like to replace it with something fundamentally better. John Rogers, of the University of Illinois, Urbana-Champaign, is one. The cells he has devised (and which are being made, packaged into panels and deployed in pilot projects by Semprius, a firm based in North Carolina) are indeed better. By themselves, he told this year’s meeting of the American Association for the Advancement of Science, they convert 42.5% of sunlight. Even when surrounded by the paraphernalia of a panel they manage 35%. Suitably tweaked, Dr Rogers reckons, their efficiency could rise to 50%. Their secret is that they are actually not one cell, but four, stacked one on top of another. Solar cells are made of semiconductors, and every type of semiconductor has a property called a band gap that is different from that of other semiconductors. The band gap defines the longest wavelength of light a semiconductor can absorb (it is transparent to longer wavelengths). It also fixes the maximum amount of energy that can be captured from photons of shorter wavelength. The result is that long-wavelength photons are lost and short-wave ones incompletely utilised.

Last week, dozens of people, including Google energy chief Rick Needham and Energy Secretary Ernest Moniz, trekked out to the California-Nevada border in the middle of the Death Valley to dedicate what is believed to be the world's largest solar thermal facility in the world. At 392 megawatts, the Ivanpah solar thermal plant will be able to power 140,000 homes — the equivalent of all of Newark (averaging two people per household). We covered the project when BrightSource, the main developer behind the project, first put up a stunning 3-D tour of the site. But for all its scale and beauty, in terms of the future of renewables, Ivanpah is already irrelevant. Solar thermal creates electricity by using mirrors to direct intense amounts of heat at a centralized collector, which is used to heat a substance like water to create steam power. Solar photovoltaic, meanwhile, directly converts solar energy into electricity through semiconductors. If solar thermal sounds unnecessarily complicated, you're right. Solar photovoltaic has seen explosive growth in the past few years thanks to plummeting material costs, state incentives, and eco-conscious homebuyers putting up panels on their roofs. But solar thermal growth has stalled, and is expected to continue to do so. Ivanpah cost $2.2 billion. Warren Buffett paid the same amount for the world's largest photovoltaic plant just up the road outside Bakersfield. That plant will generate 1.5-times as much power as Ivanpah. As the New York Times' Diane Cardwell and Matt Wald wrote Friday, Ivanpah probably represents an end, not a beginning.
A windy stretch of the Mojave Desert once roamed by tortoises and coyotes has been transformed by hundreds of thousands of mirrors into the largest solar power plant of its type in the world, a milestone for a growing industry that is testing the balance between wilderness conservation and the pursuit of green energy across the American West. The Ivanpah Solar Electric Generating System, sprawling across roughly 5 square miles of federal land near the California-Nevada border, formally opened Thursday after years of regulatory and legal tangles ranging from relocating protected tortoises to assessing the impact on Mojave milkweed and other plants. "The Ivanpah project is a shining example of how America is becoming a world leader in solar energy," U.S. Energy Secretary Ernest Moniz said in a statement after attending a dedication ceremony at the site. "This project shows that building a clean-energy economy creates jobs, curbs greenhouse gas emissions and fosters American innovation." The $2.2 billion complex of three generating units, owned by NRG Energy Inc., Google Inc. and BrightSource Energy, can produce nearly 400 megawatts enough power for 140,000 homes. It began making electricity last year.
China is projected to install 12,000 megawatts of solar power in 2014, giving it the "gold medal" in the figurative 2014 Solar Olympics, according to GTM Research . That amount will be greater than what the United States has installed in all of its solar history. Japan will take "silver" in 2014 with 7,500 megawatts forecast. The U.S. will take bronze at 5,300. "China's rise to the top in global PV installations has been impressive, to say the least," GTM Research solar analyst Adam James said in the release. "Although transparency continues to be a problem in accurately sizing the market, GTM sees the shift to production-based incentives and increased downstream financing support driving deployment to new heights over the next few years." For the first time in the past four year period, no European country will feature on the podium. "While European feed-in tariff markets have been great at the short-distance events, the global solar market is clearly aiming toward the long-distance contenders in Asia and North America," said Shayle Kann, senior vice president at GTM Research. "But don't count out emerging markets. By the time the Summer Olympics roll around in Rio, Latin America will be a PV force to contend with."
One-third of all Americans who work in solar power live in California, according to an annual survey released Tuesday. And their numbers are growing fast. The solar industry employed 47,223 Californians last year, up 8 percent from 2012, according to the survey from the Solar Foundation, a research and advocacy group. Nationwide, the solar industry employed 142,698 people. And while the rate of solar job growth nationwide was faster than in California, nearly hitting 20 percent last year, the Golden State still dominates the business. "California is, by far, the leader," said Andrea Luecke, the foundation's executive director. "It's not by accident that the solar industry is based there." Most of California's solar jobs, however, focus on panel installation and financing versus research and development efforts to create new technologies. Starting more than 10 years ago, California officials made a concerted push to foster the solar industry. They forced the state's utilities to buy more renewable power and offered rebates to homeowners who bolted solar panels to their roofs. The effort appears to have worked. Most of the country's largest solar companies are based in California, particularly in the Bay Area. The foundation's survey counted 21,653 solar jobs around the bay.
The U.S. filed a second complaint against India’s solar-energy policies at the World Trade Organization, reviving a year-old dispute between the two nations. Today’s action follows a case the U.S. filed in February 2013 at the Geneva-based WTO, saying India’s requirements for locally made components on solar-energy products violate global trade rules. “These domestic content requirements discriminate against U.S. exports” of solar cells and modules, U.S. Trade Representative Michael Froman said today at a news conference in Washington. Officials from the Indian Embassy in Washington didn’t immediately respond to a request for comment. The U.S., which has supported its own solar-manufacturing industry through loan guarantees, exported $119 million worth of solar-industry gear to India in 2011, and sales have declined since then, according to the U.S. trade office. In 2012, India, the second-largest export market for U.S. solar producers after Japan, plans to expands its solar-manufacturing industry by 20 times by 2020, according to the agency. The U.S. trade office notified India today that it’s requesting consultations at the WTO to resolve the dispute. If the matter isn’t resolved in 60 days, the U.S. can request creation of a special panel at the WTO to hear the case.
Sumitomo Corp. said it installed a power storage system using recycled electric-vehicle batteries near a solar power station in the western prefecture of Osaka. The 600-kilowatt system is the world’s first large-scale power storage system from used EV batteries, the Tokyo-based company said in a statement today. The device uses 16 used batteries. “Over the next three years, the system will measure the smoothing effect of energy-output fluctuation from the nearby,” solar farm, Sumitomo said in the statement. Sumitomo set up a venture with Nissan Motor Co. in 2010 to address the secondary use of EV batteries.

"REC Solar is the industry leader in customer satisfaction and high quality construction, while AEE Solar and SnapNrack bring capabilities that allow us to make solar energy affordable for more consumers, provide superior systems and service, and lay the foundation to become a major energy company," Jurich said.
A new $2 million funding program from the Department of Energy is expected to add – yes, add – yet another 1,800 gigawatts of wind power to the already formidable wind resources of the US. That’s something to keep in mind as the Keystone XL tar sands oil pipeline review process heats up. The idea behind the new taller wind turbine program is to give the US wind industry an assist in developing taller wind turbines, with hub heights ranging from 120 meters up to 140 meters. That’s a big step up from existing technology, which currently goes to the 80-100 meter range, with the average at about 90 meters. As for why a taller wind tower, upper level winds tend to be stronger and steadier. With taller wind turbines, the new program is also expected to open up an additional 237,000 square miles of wind-friendly areas for wind power potential, which is about the size of Texas (the image above compares the area change in square kilometers between the hub height of 96 and that of 140). The areas of the US most likely to benefit from the improved wind technology are mainly located in the Southeast, where alternative energy is starting to find a friendly reception despite pushback by certain legislators from those states.
