Primus Power's flow batteries rake in $11M

Primus Power announced today that it has raised $11 million in its latest round of funding to finance its battery technology, which store energy and provide backup power for large power grids and “smart grids” — power grids that use advanced computer algorithms to efficiently distribute electricity and minimize loss of power.

Are solar panel manufacturing component prices falling fast enough?

The price of polysilicon, a key component in manufacturing solar panels that capture sunlight and convert it to electricity, fell 5.1 percent to $74.4 per kilogram from $78.19 last month. Still, the decline is smaller than expected and the current prices could hurt profit margins for solar panel manufacturers that rely on crystalline silicon panels.

On the GreenBeat: $6 billion solar plant wins approval, Solyndra's secret sauce

Chevron Energy Ventures and Solar Millennium’s proposed $6 billion solar power plant – to be the largest in the world – has cleared approval from the California Energy Commission, according to a Reuters report. The Blythe, Calif. plant will have a capacity of 1,000 megawatts — big numbers in an industry where the largest plants are about one-third that size. Solar Millennium and Ferrostaal AG are working to develop the plant through a joint venture, Solar Trust of America. It’s unclear what role Chevron plays in the plant, according to the Reuters story. Southern California Edison has already entered a deal to purchase all of the energy generated from the first half of the project. The entire project consists of four 250 megawatt plants.

SoloPower gets safety greenlight for flexible solar modules, will expand production

SoloPower announced today that it’s the first in the solar photovoltaic industry to receive a needed safety certification for its flexible CIGS solar module — panels that are easily adhered to roofs or building materials, and made of copper, indium, gallium and deselenide (hence, CIGS). The safety greenlight paves the way for the company to debut its product line and begin commercial-scale manufacturing.
