Check out California's new "high-water" mark forsolarset yesterday -- 1,300 megawatts of power over a three-hour period of time:
For more than six hours, solar was producing more power than any other renewable energy source in California. In August 2012, the state saw a record 1,000 megawatts of power produced. This latest record was spurred by a surge of large-scale installations in the third- and fourth-quarter of 2012. California installed more than 190 MW of solar PV in Q3 and more than 400 MW of PV in Q4, with a majority of the projects at the commercial and utility scale.
