    They were very happy to correct all issues that came up with the plan and so far very satisfied with their products and services

  • "Best Price, No Compromise"

    California State Development was a pleasure to work with.

    We were very particular on where we wanted the panels to be installed. No other company was able to figure out an efficient way to arrange the panels while satisfying our constraints. But Vloddy and his team were able to find an innovative solution that is most efficient (all south facing panels) and is virtually invisible from the street.

    Their quote for our 8.16kW system was the most competitive, even compared to Tesla, and we did not sacrifice on equipment or workmanship. They are experts at the whole process -- from planning, to permitting, to install and PTO.

    We have no regrets about going with California State Development.

    I had contacted Nathan about going solar as he was referred to me from a family member. He did their solar project when he was with Solar City. My family is very careful on who they refer people to. But Nathan was very professional. He came in and explained the whole project to me. Made sure I was comfortable with the project. My husband is stationed overseas. But Nathan made time to talk to him also and explain the project front to back again to him. Nathan is a Air Force Veteran. I would highly recommend him to any person that asks
