Here’s some of the latest action we’re following today on the GreenBeat:

Trina Solar shoots for 10 percent market share — The Chinese company is the world’s No. 2 solar panel maker and plans to invest $400 million to ramp up production in an effort to take at least 10 percent of the global market, Reuters reports. Its current global market share is about 8 percent and plans to double shipments to the U.S. next year.

Cost of home solar at an all-time low — The average cost of a system fell to an all-time low of $4.10 per watt in 2009, and costs fell again in 2010, according to a new report from Lawrence Berkeley National Laboratory. Earth2Tech notes that the decrease in price coincided with a change in federal policy that allowed solar system owners to receive a tax credit for 30 percent of the system’s cost.

Solar and wind Treasury grant program wins one-year reprieve — After a fierce, last-minute push in Congress, the Senate has cleared a one-year extension of a Treasury federal tax grant program that solar and wind associations credit with bringing many jobs and projects online, Greentech Media reports. Wind and solar executives were divided on how crucial the program is, while industry associations warned of a negative impact on jobs and projects.

Another delay for a Tessera solar plant — On the heels of quickly re-winning approval for its Calico plant, Tessera Solar announced that a court has delayed the start of construction on its Imperial Valley Solar plant in California — the first utility-scale solar project approved for public lands. The delay was granted on behalf of the Quechan Tribe, which sued government entities over what it claimed was insufficient consultation during the permitting process. The project has been in development for over five years and has cost about $20 million so far. Greentech Media has reported before that Tessera is troubled, having lost executives and laid off staff.
