Southwest Sun Solar is a California based company that has offices and installation crews throughout the state. We are committed to educating the community and bringing solar power and clean energy to as many customers and households as possible Southwest Sun Solar is proud to be a California based company. Southwest Sun Solar is a company that can do it all; our in-house team designs, engineers, builds, and maintains solar projects that range in size from a small 1kW residential system all the way up to a multi-megawatt commercial or utility system. Our team will take care of all aspects of the project, from design to permitting, installation all the way to the PTO (Permission to Operate). Unlike many of the large companies that hire outside contractors to do their installations, our company is vertically integrated, allowing us control of the entire solar installation process from start to finish. The vast majority of negative reviews from dissatisfied solar customers originate with the companies that hire subcontractors to do some or all of the various aspects of the project design and installation. We have complete control of our projects allowing us to finish projects within 4 weeks from the date of signing up for solar.
