Semper Solaris review

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.

What People Love:

• The Work Quality Is Solid: Reviewers kept using words like “excellent,” “exceptional,” and “transformative” when talking about the roofing work.
• Crews That Know What They’re Doing: Installation teams consistently showed up on time, worked efficiently, knew their stuff, and acted professionally. Jobs often wrapped up fast—like in 3 days—and they cleaned up the site properly afterward.
• Good Project Management: Certain project managers, like Timothy, got called out by name for being reliable, pleasant, really organized, and offering helpful recommendations throughout the process.

What’s Causing Major Problems:

• They Disappear After Installation: This is the biggest complaint by far. Once installation is done, customers face serious issues—solar panels stop working, a $30K HVAC system fails to cool the house for years—and getting help becomes nearly impossible.
• They Diagnose But Don’t Fix: One customer paid $299 just to have someone diagnose why their solar panels weren’t producing power. Two months later? Still nothing done.
• Nobody Takes Responsibility: Customers report getting the runaround for weeks or months. When a system fails, it can take weeks just to get a technician scheduled, and then they cancel or postpone at the last minute.

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.

The Good Experiences:

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.

The Bad Experiences:

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.

What Employees Appreciate:

• Having a sense of purpose and opportunities to learn new skills
• Some workplace flexibility and feeling respected
• Supportive ownership

What Employees Don’t Like:

• Pay isn’t great according to some
• Job security is shaky—there are reports of frequent layoffs
• Some reviews mention integrity issues with management and a hostile work environment
• The company doesn’t respond well to customer concerns

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.

Average Performer

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. When considering this solar installer, you can add Semper Solaris to your list as a lower priority and one that requires additional research before you decide to work with them.
