US regulators have approved projects totaling $515m to more than double the amount of solar power generation in the state of New Jersey, it has been announced.

The move is set to cement the state’s No. 2 spot behind California in power produced from the sun, writes the Associated Press.

The State Board of Public Utilities gave the green light to proposals from four utilities that together will yield 145MW of solar energy.

The power produced is expected to be enough to power about 130,000 homes, boosting the state total to 232MW.

Jersey Central Power & Light company was given the contract for 42MW of solar power through to 2012. Atlantic City Electric Company was cleared for 19MW and Rockland Electric Company, for 3.8MW, according to the Associated Press.
