G.E. Plans to Build Largest Solar Panel Plant in U.S.

SAN FRANCISCO — In a move that could shake up the American solar industry, General Electric plans to announce on Thursday that it will build the nation’s largest photovoltaic panel factory, with the goal of becoming a major player in the market.

The plant, whose location has not been determined, will employ 400 workers and create 600 related jobs, according to G.E. The factory would annually produce solar panels that would generate 400 megawatts of energy, the company said, and would begin manufacturing thin-film photovoltaic panels made of a material called cadmium telluride in 2013. While less efficient than conventional solar panels, thin-film photovoltaics can be produced at a lower cost and have proven attractive to developers and utilities building large-scale power plants.
