CARSON CITY — Another major rooftop-solar company announced Thursday it is ceasing all operations in Nevada as a result of a new net metering rate adopted by the Nevada Public Utilities Commission last month. Sunrun, the largest dedicated residential solar company in the United States, said it has ceased all operations in Nevada, resulting in hundreds of job losses. Sunrun said the layoffs and its exit from Nevada are the direct result of new rules adopted by the PUC, "as well as actions taken by NV Energy and Nevada politicians." Sunrun said in its announcement that it hopes to transition its Nevada-based employees to other positions within the company where possible or place them with other local organizations. The company did not immediately provide a figure on the number of job losses that will result from the decision. Net metering allows homeowners with rooftop-solar installations to receive a credit for the excess electricity they generate. Sunrun joins SolarCity in leaving the state.
