Reviews

What customers say

Customers praise clear communication, professionalism, and respectful crews. One solar customer says device problems delayed getting the system fully up and running, but the team followed through; another says a replacement Powerwall was installed and working 40 minutes after the crew arrived. A customer seeking a small gutter job reports that the estimator lacked gutter experience, tried to sell other services, and never sent the promised quote.

Angie was such a pleasure to talk to and shared her expertise in regards to our solar panels, batteries and general knowledge of our system. I’m so glad I had the opportunity to learn about our solar panels and how to maximize their efficiency and I’m excited to reap the benefits of the changes that were made. Angie you were amazing and I look forward to contacting you in the future if I have any further questions or concerns. Best of luck. Regards Gail Rodriguez

I had a great experience with Semper Solaris from start to finish. Like any big project, there were a few bumps along the way because a couple of devices had issues and it took some time to get the system fully up and running. But what really stood out to me was how the team handled everything. They were punctual, professional, and communicated clearly throughout the entire process. Every crew that came out was respectful of my home and took pride in their work. I especially want to recognize Daisy Trejo. She was truly on top of my project from day one. Daisy worked incredibly hard behind the scenes to make sure everything was moving forward and that my system became fully functional. She followed up consistently, stayed proactive, and made sure issues were addressed without me having to chase anyone down. That level of dedication makes a huge difference. Now that everything is up and running, I’m very happy with my solar installation and the overall experience. I appreciate a company that stands behind their work and sees a project through to completion. I would definitely recommend Semper Solaris to anyone considering going solar.

Found this company on Yelp when I needed a small gutter added to my home. They responded as a potential group to help me. The initial contact was outstanding. Staff friendly and quick response. From there is did not do so well. 1. The individual who was sent to give me the quote, Cody, was late with no call or text indicating that he was running late. I had to call. 2. Once here, I learned he had not done gutters or the type of corners I was having trouble with. 3. He tried to upsell me with other services. Running through a list. Tried to sell me solar, roof, air conditioning, house wind. I already had solar with a well known company that is very much still in existence. But he did not even recognize the name of Sunlux, assumed they were out of business. (Nope) 4. Never received the quote he promised, to be sent hours later. Seems their focus is really solar or air conditioning. Not gutters. Why even quote me then? Why respond ? I said it was an extremely small project with photos. I liked the initial appointment staff, was even ready to hire them in the spot if the quote was reasonable... but the lack of follow through and extreme high energy and loud voice of the estimator, ended that . I was expecting a person who would do the work themselves or who leads a team. I got someone who had no direct experience and needed a computer to give a quote. I liked supporting a veteran owned company, but no thanks. Complete waste of everyone’s time.
