About Semper Solaris
Semper Solaris operates from Santa Ana as a residential solar energy contractor serving Orange County homeowners, including those in neighboring Irvine and Anaheim. With a 4.6-star average drawn from 163 verified customer reviews, the company has cultivated a solid reputation over multiple years of operation in Southern California. Their crews handle solar panel installations and related electrical work, with extended service hours beginning at 7 AM weekdays and Saturday, plus Sunday availability starting at 9 AM. The contractor specializes in turnkey residential projects that combine panel arrays with battery storage solutions for homeowners seeking energy independence.
What distinguishes Semper Solaris from many competitors is their hands-on guidance through incentive programs. One reviewer credits sales consultant Gil with identifying eligibility for the SCE SGIP grant, which reduced the total project cost to one-third of the original estimate. The company installs Tesla battery systems alongside traditional solar panels, enabling customers to operate entirely off-grid or cushion against utility rate spikes. Several five-star reviewers specifically praise the installation teams for maintaining clear communication throughout the project timeline and conducting follow-up checks after completion to confirm system performance.
Brad Thomas describes how Gil assessed his property and recommended the SGIP grant program during their first meeting, a detail all three competing firms overlooked. His resulting 36-panel system with three Tesla Powerwalls now operates independently from the grid. Installation supervisor Brian J earned commendation from reviewer Ellie Marlow for professional conduct during an annual maintenance visit. C A Ferguson notes the entire process from contract signing to final inspection wrapped within three weeks with a single-day physical installation, and the crew followed up afterward to verify satisfaction.
What Customers Say
Five of seven detailed reviewers award five stars, with praise focusing on installation speed and post-project follow-up. Two negative reviews center on delayed service responses after installation, particularly for repair requests related to a non-functional transponder and roofing damage attributed to faulty mounting. Named staff members Gil, Brian J, and the on-site crew receive specific commendation for technical knowledge and professionalism.
