Far West Rice Mills in Nelson, Calif., on Wednesday dedicated a one megawatt solar array that will provide three-fourths of its electricity.
The array is made up of 5,500 solar panels from Mitsubishi Electric & Electronics and was installed by Pacific Power Management.
Mitsubishi said that it's the largest solar-powered rice mill in the U.S.
Corporate solar installations in this range--Google's solar array at its headquarters generates 1.6 megawatts--are the biggest area for growth in the solar industry.
Corporations and agribusiness invest in these systems to get a predictable electricity price over several years, hedging against rising prices.
The Far West Rice Mills installation will deliver 1,440,000 kilowatt hours a year and qualifies for $1.8 million in rebates from Pacific Gas & Electric.
