My home solar system was installed by Southwest Sun Solar of Orange county office back in July 2022. After nearly eight months of enjoying this system, it is continuing to produce electricity for my home without any issues. This system is generating my home electricity is better than initial specs of the contract. All personals of the company from customer services, and installation guys are courtesy and helping during all phases from contract, obtaining city permit and installation. The final product are quality and well prepare with installation to meet the city requirements. We are no longer worrying about monthly electricity bills from my local SDGE. I would recommend this company to any ones who are looking for their home solar system. Thanks to the company with well done job and special thanks to Huy for making it happened.

Excellent Solar Installation and Service

I had Solar installed and love it. My electricity bill has substantially decreased and the install was painless. SWSS made installation quick and easy. They were very clean in the process and put my worries at ease. I didn't think it would be this painless to get it installed and never thought I'd be saving this kind of money. Looking forward to running the AC a lot this summer without the insane bills! Thanks SouthWest Sun Solar.

About Southwest Sun Solar

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.
