California Green Energy Construction
I chose to work in this industry because because our family has been licensed in construction since 1972, with 80 years of combined experience in general contracting, electrical contracting and solar contracting. Our first solar install was in 1998 and since then, we have been involved in projects as small as an off-grid battery system to supply energy demand for a small irrigation pump, to projects as large as retrofitting the electrical infrastructure on Alcatraz Island with solar panels and battery backup. We choose to focus our work in the solar industry because of the drastic push for renewable energy in the United States and the annual increases in grid electricity costs. Our family has decades of expertise in many different facets of construction, especially in solar, which places us above our competitors when a customer is relying on experience and accountability..
We started in this industry in 1998.
We describe our business as Family owned and operated.
