SolarCity has laid off more than 550 employees in Nevada. This comes two weeks after the company announced it was halting the sale and installation of rooftop solar panels in the state, after the Public Utilities Commision approved cutting the rate NV Energy pays solar customers for generating excess power. SolarCity, one of the largest providers of rooftop solar in the country, also began dismantling a Las Vegas training center, and will close warehouses in Reno, Henderson, and North Las Vegas.
