California set back-to-back solar power records last week, the state grid operator said on Monday.

The amount of electricity produced from carbon-free solar facilities connected to the grid reached 4,093 megawatts on Saturday, surpassing the day-earlier record of 3,926 MW, the California Independent System Operator (ISO) said in a statement.

With 5,231 MW, California leads the nation in installed solar generation, including thermal and photovoltaic facilities, according to the Solar Energy Industries Association.

Power generated from solar has more than doubled from June 2012 when the ISO recorded 2,071 MW of peak production, the ISO said.
