GenOn Energy Inc. and NRG Energy Inc. (NRG), the company acquiring it to create the largest US independent power producer, were sued by a shareholder claiming the US$1.7 billion all-stock deal undervalues the company.

OCI Solar Power signed a deal with CPS Energy today in San Antonio, Texas, to develop, own and operate the largest municipal utility solar project in the country.

The Los Angeles Department of Water and Power has unveiled a solar plant it says can power 3,300 homes a year.

In a new filing in the case between the two technology giants in California, which was picked up by FOSS Patents, Samsung notes that Apple took the liberty of sending do-not-sell letters to carriers and retailers that carry Samsung's products.

The US solar industry is undergoing some serious growing pains, with bankruptcies and mergers a necessary part of that process; meanwhile, competition from China-based solar panels has many believing that US solar simply cannot compete.

Imports of China-based solar cells and panels into the US decreased for the second straight month in May on year, according to the Coalition for American Solar Manufacturing (CASM).

Applications for jobless benefits decreased by 26,000 in the week ended July 7 to 350,000, the fewest since March 2008.

The dust is yet to settle on tariff determinations against China-based manufacturers, but the Coalition for American Solar Manufacturing (CASM) has released a statement warning of a "conspiracy to commit offense or to defraud the US".

Solar power has long been touted for its environmental impact. But now it has a new role: saving teachers' jobs.

The US Department of Commerce (DOC), responding to last autumn's petitions by SolarWorld and other members of the Coalition for American Solar Manufacturing (CASM), announced preliminary duties of 2.9-4.73% on crystalline silicon solar PV cells to counter Chinese subsidies to its solar PV manufacturers.

Solar installations in the US jumped 85% in the first quarter of 2012 from the previous year, according to an industry report that prompted a research firm and a lobbying group to raise their capacity forecasts for the year.

China is developing third-generation photovoltaic technology, which may help China-based solar makers circumvent heavy duties imposed by the US, according to He Zuoxiu, an academician at the Chinese Academy of Sciences.

US renewable-energy subsidies in five states violate free-trade rules, China's Ministry of Commerce said today.

California is poised to more than double its targeted electricity output from rooftop solar panels.

Solar companies Suntech Power Holdings Co Ltd and Trina Solar Ltd said their first-quarter margins were squeezed as they set aside money to offset anti-dumping tariffs imposed by the US government on solar panel imports from China.

A move designed to punish China-based solar panel makers that charge unfairly low prices in the US could, ironically, end up hurting American-based solar panel installers, a fast-growing sector of the green economy.

China-based solar panel manufacturers are making plans to source components from Taiwan in order to get around US anti-dumping tariffs of at least 31% announced by the Department of Commerce last week.

China unleashed a storm of protest Friday on multiple fronts against the US decision to impose a 31% antidumping tariff on Chinese solar-panel makers and said the action could backfire on US industries.

The move, announced by the Commerce Department, is certain to infuriate Chinese officials already upset after recent bilateral frictions over China's human rights policies and its increasingly confrontational approach toward American allies like the Philippines and Japan.

The US yesterday imposed tariffs of as much as 250% on Chinese-made solar cells to aid domestic manufacturers beset by foreign competition, though critics said the decision may end up raising prices and hurting the US renewable energy industry.

SolarWorld said its Hillsboro, Oregon-based U.S. unit can't compete with Chinese exporters, including Suntech Power Holdings Co. (STP), the world's largest solar-panel maker, and Trina Solar Ltd. unless tariffs are imposed. Suntech was told to pay 31.22%, Trina's levies were set at 31.14% and others were told to pay duties ranging from 31.18-249.96%.

The US solar-power industry has been nervously awaiting a federal decision on whether to impose antidumping tariffs on Chinese solar-panel makers.
