Solar Installation Experience Since 1978
More than 35 years ago, RGS Energy – a Real Goods Solar Company – sold some of the very first solar panels to the public out of a small general store in Northern California. Since then, we’ve installed over 22,500 solar energy systems for homes, businesses, schools, government facilities, and utilities across the country, totaling more than 235 megawatts of clean energy.
