| Services Offered | Solar Power Installation: They provide the best solar panel options for their customers and their specific needs. Battery Storage: Solar battery storage consists of a device that stores reserve energy from a connected solar system. The stored electricity is consumed after sundown, during energy demand peaks, or during a power outage. Roofing Services: They offer a complete roofing system that creates a waterproof barrier, defends against the elements, and provides proper ventilation. Heating, Ventilation, and Air Conditioning (HVAC): Semper Solaris offers heating and air conditioning services. By switching to an energy-efficient heating or air conditioning unit, you can reduce your electric bill significantly. |
| Roofing service | yes |
| Panel Options | Polycrystalline Solar Cells: These panels are made by melting raw silicone and pouring that melted material into molds. Once cooled, they are cut into square wafers. They are more affordable but have less tolerance towards heat than monocrystalline panels. Their efficiency is 13-16% on average. Monocrystalline Solar Cells: Known to be some of the purest silicon-based solar panels, they boast a uniform appearance and coloring. They are designed to lower costs of a single solar cell and maximize the space, making it as efficient as possible. Their efficiency ratings tend to range from 15 to 20%. However, they are the most expensive investment. Thin-Film Solar Cells: These are made by layering thin layers of photovoltaic material onto a substrate. The materials used to make these solar cells can range from amorphous silicon to copper indium gallium selenide. Their maximum efficiency caps out around an optimistic 13%. |
| Battery Installations | Tesla Powerwall: This solar battery, created by the engineers who brought you the iconic electric vehicle, is capable of storing around 13.5 kWh of energy charged directly by excess solar energy produced by your solar system. Enphase Encharge: This uses a one-of-a-kind microinverter system that places multiple microinverters in every battery, assuring there is no single point of failure. That means the power flows and the lights stay on when you need them the most. |

On the plus side, Semper Solaris makes a real effort to help people understand how solar actually works and figure out which system makes sense for them. They also have a strong commitment to hiring veterans, valuing the work ethic and discipline that comes from military service.
That said, there are some concerning experiences from customers. One person called out deceptive practices and felt manipulated throughout the process. They ran into major delays getting their service activated and weren’t happy with how the workers behaved on site. What really bothered them was being blindsided by costs—specifically around uninstalling and reinstalling panels—that nobody mentioned upfront.
When things go well, they go really well. One San Diego customer had nothing but good things to say about their HVAC and solar installations—everything ran smoothly and the teams were professional.
But when things go wrong, they go really wrong. Someone in Antioch, California watched their price jump over 30% in just 9 months, and their system hasn’t worked right since day one. Another person in Reseda got burned by false promises about what it would cost to uninstall and reinstall their panels.
Semper Solaris holds BBB accreditation with an A+ rating, which reflects how the BBB views their customer interactions and complaint handling.
However, the customer experience tells a different story. One customer detailed a rough installation with delays, property damage, and terrible communication. The company apparently failed multiple inspections because what they installed didn’t match what they submitted in their designs.
The ratings paint a stark picture: 24% are 5-star reviews, but 67% are 1-star. That’s a huge number of unhappy customers.
Some customers genuinely loved their service. One person’s solar system has been running strong for three years and works great, especially during brutal summer heat.
Poor communication, installation delays, and subpar work show up repeatedly in complaints. One customer’s roof started leaking right after the panels went up. Another couldn’t get anyone to address their concerns in a timely manner—or really at all.
Reviews highlight the company’s professionalism, service quality, and value when things work out. One customer praised the entire experience, mentioning the team’s honesty, expertise, and integrity.
On the flip side, one person had a terrible time with surprise charges, an inverter that shorted out due to negligence, and zero response from the company when they tried to get help.
Semper Solaris gets mixed feedback from customers. While 24% of reviews are 5-star, a concerning 67% rate them 1-star.
Complaints center around poor communication, installation delays, and shoddy workmanship showing up way too often.
As always, it’s smart to read through multiple reviews before deciding whether to work with them.
Summarizing:
Semper Solaris gets the Average Performer badge and works in 5 states, but their third-party ratings don’t go above 4. Local community trust isn’t their strong suit either – their score is 3.9 in our evaluation. This badge means they are somehow reliable, but you need to pay more attention to what they have to offer. While Semper Solaris may not lead the pack, they are certainly recognized for their capacity to meet a broad range of solar installation needs with commendable customer satisfaction.
