About Semper Solaris
Semper Solaris has served Bakersfield residents since establishing their solar energy practice in the region, accumulating 74 customer reviews that collectively award the company a 4.2-star rating. The business operates from extended hours across every day of the week, with Monday through Saturday service beginning at 7 AM and concluding at midnight, while Sunday appointments start at 9 AM. Homeowners throughout Kern County and surrounding Central Valley communities turn to this contractor for both new solar panel installations and system maintenance, with the company additionally handling related HVAC and roofing needs that frequently accompany solar projects.
What distinguishes Semper Solaris from regional competitors stems from their multifaceted expertise spanning both solar generation and climate control systems. The company maintains active partnerships with major equipment providers including Tesla for battery storage solutions, enabling customers to participate in utility grid programs that occasionally generate bill credits rather than charges. Their technicians arrive with specialized diagnostic equipment capable of reading system performance tolerances and electrical output metrics, allowing for precise problem identification before any repair work begins. This technical transparency, combined with detailed explanations of diagnostic findings, empowers homeowners to understand exactly what their systems are producing and consuming.
Customer experiences documented in recent reviews illustrate the company's service approach through specific technician encounters. Josh, a service technician, demonstrated notable responsiveness by calling ahead of scheduled appointments and walking a homeowner through troubleshooting steps that ultimately resolved the issue without a follow-up visit. Another homeowner credited Robert Alva with addressing a solar system concern that had caused ongoing anxiety, while Brian J. performed an A/C service call in April that included installation of a hard start kit and motor control components, taking time to explain each diagnostic reading along the way.
What Customers Say
Three of five detailed reviews award five stars citing specific technician names and problem resolution, while one negative review from a solar customer describes billing complications involving third-party providers and PG&E charges. The positive feedback consistently highlights technician communication and educational explanations during service calls.
