Ryan Wallace for The Science Times: Known as the "Powerwall", Tesla's newest invention is a thin, wall-mounted battery that is the size of a flat screen TV. And with this new battery home owners who have already invested in solar power will be able to entirely go off the grid, and even to sell their excess solar juice back to energy companies. Developed in conjunction with the lithium-ion batteries that Tesla uses for its electric vehicles, the Powerwall unit is an inexpensive unit, only running $3,000 to $3,500, and with it Musk and his companies believe that humans may one day be able to transition to solely using energy derived from the Sun. Though the installation may look like an artpiece, it packs quite a punch at 10 kWh, and with it consumers will not only be able to store their energy for dark solar-free nights, but also more efficiently contribute to global energy use by contributing carbon-free energy back into the mix.
Tesla Powerwall to be Offered Through Sunrun Subsidiary AEE Solar
Late Thursday night in Los Angeles, Tesla announced "Tesla Energy," described by the company in a statement as "a suite of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels." The statement continued: "Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation." Tesla CEO Elon Musk made the official announcement onstage at the company's design studio in Hawthorne, CA, just south of LA. The home battery, call the "Powerwall," is intended to store solar energy and enable customers to bank grid electricity from non-peak periods and use it during peak times, saving money. It looks "like a beautiful piece of sculpture," Musk said. You can order it now, and it comes in different colors. "The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation," Tesla said. "The Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve."

Professor Donald Sadoway remembers chuckling at an e-mail in August 2009 from a woman claiming to represent Bill Gates. The world’s richest man had taken Sadoway’s Introduction to Solid State Chemistry online, the message explained. Gates wondered if he could meet the guy teaching the popular MIT course the next time the billionaire was in the Boston area, Bloomberg Markets magazine will report in its May issue. “I thought it was a student prank,” says Sadoway, who’s spent more than a decade melting metals in search of a cheap, long-life battery that might wean the world off dirty energy. He’d almost forgotten the note when Gates’s assistant wrote again to plead for a response. A month later, Gates and Sadoway were swapping ideas on curbing climate change in the chemist’s second-story office on the Massachusetts Institute of Technology campus. They discussed progress on batteries to help solar and wind compete with fossil fuels. Gates said to call when Sadoway was ready to start a company. “He agreed to be an angel investor,” Sadoway says. “It would have been tough without that support.” Sadoway is ready. He and a handful of scientists with young companies and big backers say they have a shot at solving a vexing problem: how to store and deliver power around the clock so sustainable energies can become viable alternatives to fossil fuels. How these storage projects are allowing utility power customers to defect from the grid is one of the topics for debate this week at the Bloomberg New Energy Finance conference in New York. Today’s nickel-cadmium and lithium-ion offerings aren’t up to the task. They can’t run a home for more than a few hours or most cars for more than 100 miles (160 kilometers). At about $400 per kilowatt-hour, they’re double the price analysts say will unleash widespread green power. “Developing a storage system beyond lithium-ion is critical to unlocking the value of electric vehicles and renewable energy,” says Andrew Chung, a partner at Menlo Park, California–based venture capital firm Khosla Ventures.

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
