SolarWorld, the largest crystalline silicon solar producer in the Americas for nearly 40 years, announced that in 2015, it would add a solar-panel production line in Hillsboro to bring the panel-assembly factory's capacity up to 530 megawatts (MW), expand advanced cell production capacity by 100 MW and add 200 jobs. "It is no secret that the last several years have been tough for SolarWorld and for U.S. solar manufacturers in general," SolarWorld U.S. President Mukesh Dulani said. "However, thanks to a variety of factors, including our trade cases against China, difficult but necessary financial controls and a fantastic group of employees, we have turned the corner. Today's announcement shows that SolarWorld is not only here to stay, but it also is ready to extend our leadership in the American solar manufacturing industry." Dulani was joined at a morning news conference by U.S. Sen. Ron Wyden (D-Ore.), chairman of the U.S. Senate Committee on Finance. Sen. Wyden received a commemorative plaque thanking him for his years of support for SolarWorld and its workers during the cases. He also spoke at a SolarWorld employee forum after the news conference.
Sunrun, the largest dedicated residential solar company in the United States, today announced a partnership with OutBack Power Technologies, Inc. to pilot renewable energy storage-based systems for a select group of Sunrun solar customers.

"With OutBack Power, we will further our commitment to providing customized and affordable home solar that allows customers to be a part of the solution for building a clean, modern grid that provides power when it is needed the most."
Have you ever noticed energy blogs or articles about small wind turbines comparing them directly with big wind technology and solar? I am writing this article to provide a little background on where small wind turbines can be very successful and where they make absolutely no sense. It also explains why the market for “Small Wind” is vastly different from that of “Big Wind.” First of all, “Small Wind” has been defined by the American Wind Energy Association (AWEA) as any turbines under 100 kW of rated power. As we all know, 100 kW wind turbines aren’t small! Therefore, others have decided to define them as anything up to 10 kW. For the purpose of this article, we use the same definition as AWEA, up to 100 kW. Full Article:
Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives. That means homeowners who add solar panels to save money on utility bills will continue to lose electricity during blackouts, even after an 80 percent decline in battery costs over the past decade. Residential solar systems typically send power to the grid, not directly to the house, and don’t run the home during a blackout. For batteries to save consumers money, stored energy must be drained daily, said Jamie Evans, who runs the U.S. Eco Solutions unit for Panasonic Corp., which supplies lithium-ion cells for Tesla Motors Inc. “Solar will need storage for grid stability,” Evans said yesterday in an interview at the Solar Power International convention in Las Vegas. “Battery costs need to come down and regulatory structures have to change to really scale up.” As residential solar become more common from California to New York, utility grids will increasingly become stressed without storage to ease supply and demand imbalances, he said. For now, that means battery storage only makes economic sense for large businesses that get hit with extra fees when their power usage exceeds utility expectations.

The largest military contractor in the United States is developing a nuclear fusion reactor that is small enough to fit on the back of a truck but has the ability to produce the energy required to power a warship. Lockheed Martin said in a statement released on Wednesday this week that its secretive Skunk Works division — the unit responsible for the U-2 spy plane and F-117 stealth jet — has already applied for several patents related to the high-tech reactor it has in the works, and expects it to be deployed during the next decade if interested industry and government partners sign on to help starting soon. “Our compact fusion concept combines several alternative magnetic confinement approaches, taking the best parts of each, and offers a 90 percent size reduction over previous concepts,” Tom McGuire, the compact fusion lead for the Skunk Works’ Revolutionary Technology Programs, said in a statement. “The smaller size will allow us to design, build and test the CFR in less than a year.”
With less than one week before the largest North America solar trade show, SPI, kicks off in Las Vegas, visitors are being advised to expect to spend their day on their feet. With the two South Halls of the Las Vegas Convention Center being consumed by the exhibition, organizers say that attendees can expect to take many more than 10,000 steps a day. Unique booth designs and companies going “all out” are to be expected at SPI this year, according to organizers with Hanwha Q CELLS taking out the largest booth space. 25% of the exhibitors are from outside of the U.S., with 23 countries being represented. Chinese, Germany and Spanish country pavilions will also occupy large sections of the trade show floor. Of the U.S. exhibitors, Californian companies represent the largest group, making up 31%. The state is followed by Texas, Colorado and Ohio – with each of these states comprising 5% of the total number of exhibitors.
SolarCity, the nation's largest residential solar installer and financier, is coupling Tesla's battery-based energy storage hardware with its rooftop solar systems. Peter Rive, the co-founder and CTO of SolarCity, spoke at last week's Energy Storage North America conference and said that the standard offering from SolarCity could eventually include storage. Rive added that the combination of solar and storage "won't look that much different for the customer," but that "the benefit to the customer will be that you will have a little backup power." Defecting from the grid? A recent RMI blog post contends that "continued rapid declines in the cost of solar and the start of the same trend for storage mean that grid parity may come much sooner than previously thought -- and well within the 30-year planned economic life of typical utility investments." When asked about this report on the economics of consumers defecting from the grid, Rive had this to say: "I hope it doesn't happen. I don't think it makes sense for someone to remove themselves from the grid. If you think about the load on a circuit as opposed to an individual home, an average home on a circuit is maybe 3 kilowatts peak. But you may find that any given home will go up to 10 kilowatts at any given time. That means the battery would have to be sized to 10 kilowatts."
A proposed “tower power” solar power plant near Joshua Tree National Park that drew heavy opposition from environmental groups has been scrapped. An application to state regulators for the Palen solar power project, a joint venture by Oakland-based BrightSource and the Spanish solar power giant Abengoa Solar, was withdrawn recently. Two 750-foot towers were originally proposed for a nearly 2,000-acre east Riverside County project that would have been near Joshua Tree National Park and the Pacific Flyway, a path migrating birds travel that often includes a rest in the Salton Sea. David Lamfrom, California Desert programs manager for the National Parks Conservation Association, said the project had the potential to be more damaging to wildlife than the 450-foot Ivanpah towers. State regulators recently ordered the project scaled back from two towers to one. “After carefully reviewing the proposed decision recommending approval of one tower, as well as other aspects of the development, we determined it would be in the best interest of all parties to bring forward a project that would better meet the needs of the market and energy consumers,” Joe Desmond, senior vice president of marketing and government affairs at BrightSource, said in a statement.
“Airport interest in solar energy is growing rapidly as a way to reduce airport operating costs and to demonstrate commitment to sustainable airport development,” says the website of Harris Miller Miller & Hanson Inc., a consulting firm that helped write the FAA’s regulatory guidance for solar power at airports. Right now, airport operating costs are high, so high that the majority of airports lose money every year. A substantial portion of those costs come from energy use. In fact, the Airport Cooperative Research Program says airports are one of the largest public users of energy in the country. In terms of expenses, energy is often the second largest operating expense, exceeded only by personnel, according to the ACRP. One way to reduce energy costs is simply to reduce electricity use, which is why many airports have taken to installing solar projects. That’s because when the initial cost of the installing the project is paid off, the airport essentially provides free electricity to itself, disregarding the cost of maintenance. That scenario, however, is only possible if the airport decides that it would like to privately own the solar operation — something that does not happen widely in the United States due to the substantial cost involved. What happens far more often is that airport solar projects are owned by private companies, which unlike airports, are eligible for tax credits. The airport, in most cases, acts solely as the property owner.
The US wind power industry still needs subsidy to compete with fossil fuels, according to Germany’s Siemens, one of the world’s largest wind turbine manufacturers. Lisa Davis, who took over in August as the head of Siemens’ global energy business, told the Financial Times that although wind power in the US was close to “grid parity” – the level at which it becomes competitive with other sources of electricity – “we’re not there yet”. Her comments come as the US industry is urging Congress to reinstate the tax credit for wind generation, which expired at the end of last year. The American Wind Energy Association has warned that the industry could face falling investment and employment if the credit is not restored quickly. Lazard, the investment bank, calculated recently that in parts of the US with strong wind, it could be a cheaper source of power than gas-fired generation, after steep declines in the cost of turbines. However, Ms Davis argued that costs still needed to be cut further before wind could compete on equal terms with gas. “We’ve not yet got to the point where it’s truly self-sustaining,” she said. “We’ve got to focus on cost competitiveness.”
Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device invented at The Ohio State University is both: the world's first solar battery. In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they've succeeded in combining a battery and a solar cell into one hybrid device. Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. The university will license the solar battery to industry, where Yiying Wu, professor of chemistry and biochemistry at Ohio State, says it will help tame the costs of renewable energy. "The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy," Wu said. "We've integrated both functions into one device. Any time you can do that, you reduce cost." He and his students believe that their device brings down costs by 25 percent.
An 8.6 kWh lithium-ion solar energy storage system for residential and commercial use has been launched by JuiceBox Energy. It is designed to work with grid-tied or off-grid solar systems. It features a system controller so the battery can be used as back-up power to a grid, thus enabling peak shifting and demand charge reduction. Notice these capabilities go beyond mere storage. In other words, battery technology can be smart and interactive in addition to storing electricity. The system has a battery based inverter, and management system for charging and discharging. Diagnostics are part of the design, too, to monitor the system for potential faults. JuiceBox will be available in the fourth quarter of 2014, with greater volume production beginning in 2015. “Energy storage is the critical technology that allows unrestrained solar growth enabling a clean energy future and a more resilient grid,” explained Neil Maguire, CEO of JuiceBox. JuiceBox is taking advance orders, but it isn’t clear yet what the price is.
A class of compounds first uncovered in the Ural Mountains more than a century ago is now a rock star in the world of solar-energy research. Meet perovskite, the building block for materials that, as a group, have posted unprecedented gains in their solar-energy efficiency—the percentage of sunlight converted into electricity. In the lab, scientists experimenting with perovskite-based materials of different compositions have recently achieved a jump in efficiency to 20%, from around 10% just two years ago. That is still lower than the most efficient silicon-based cells on the market— SunPower Corp. makes cells that are 24% efficient. But because of perovskite's rapid increases in efficiency, researchers think it could be used to make cells that are at least as efficient as those fashioned from silicon, but at a much lower cost.
For Southern California Edison (SCE), building a smarter grid started many years ago with smart meters and upgrades in distribution equipment. Today, the company takes another leap forward with the opening of the largest battery energy storage project in North America — the Tehachapi Energy Storage Project — to modernize the grid to integrate more clean energy. The demonstration project is funded by SCE and federal stimulus money awarded by the Department of Energy as part of the American Recovery and Reinvestment Act of 2009. The 32 megawatt-hours battery energy storage system features lithium-ion batteries housed inside a 6,300 square-foot facility at SCE's Monolith substation in Tehachapi, Calif. The project is strategically located in the Tehachapi Wind Resource Area that is projected to generate up to 4,500 MW of wind energy by 2016. "This installation will allow us to take a serious look at the technological capabilities of energy storage on the electric grid," said Dr. Imre Gyuk, energy storage program manager in the energy department's Office of Electricity Delivery and Energy Reliability. "It will also help us to gain a better understanding of the value and benefit of battery energy storage." The project costs about $50 million with matching funds from SCE and the energy department. Over a two-year period, the project will demonstrate the performance of the lithium-ion batteries in actual system conditions and the capability to automate the operations of the battery energy storage system and integrate its use into the utility grid.

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
