Review by in La Mirada, CA
Rae the solar consultant has done an outstanding job for my family from explaining the system to designing the perfect system to showing us step by step what are panels are doing to produce electrical power for our house. Once the system was up and running she came out and walked us through the on/off breakers and switches. Carlos Martinez was my construction manager for my roof installation. He was OUTSTANDING. He explained everything step by step and always kept me up to date on the next step/process. Him and his work crew did an awesome Job......

Our home inspector recommended Semper Solaris since they did his home. We met with Bob King who got us all set up. We were in the middle of a refi and Semper kept up with us and waited until we were ready to move forward. That was huge. It was a flawless install â they explained what each step was throughout the process. Semper kept us apprised of all the inspections and handled all of it. Now that our system is turned on weâ ve seen savings and love having the freedom to use energy the way we want to â we like it colder especially in the summertime! Highly recommend working with Semper Solaris and Bob King for all your solar needs

This is a great company to work with. They are awesome about communicating through every step of the process. Everyone in the company that we dealt with was friendly, knowledgeable and helpful. No hidden costs, very up front and made sure we got exactly what we needed. Thanks!

Our solar consultant Raedene Solano was clear in explaining the process. Very reputable company. Everything was laid out and happened as expected. Overall, great to do business with Rae and Semper Solaris.

I chose Semper Solaris after looking at a lot of different companies. Semper offered the right panels. I read a lot of reviews and felt like Semper had what I was looking for. Working with Bob King was fine. He was very straightforward. The crew was pretty good. They were happy and enthusiastic. Sun Power had an issue with the microinverters so we had them replaced in December and the system is working better. I will definitely recommend Semper to friends and family and provide my experience with the company.

Review by in Oceanside, CA
After spending several hundred dollars a month on electric bills. We finally decided to look into solar. Our sales rep. Chase Calkins explained everything about solar and the quality of the products they offer. He took the time to ensure all our questions were answered and we were comfortable and happy with our decision to go solar. The install crews did a great job and were very professional. Semper Solaris you are the best!

Review by in San Bernardino, CA
Needed some solar panels for my company and I didn t know where else to go because so many other companies that I tried were either too rude, or they had ridiculous prices and a crazy wait time. I was able to find Semper Solaris through a friend and I don t regret that choice since. They were so professional with their work and did it all in a timely manner! I definitely got my money s worth with Semper Solaris and will be spreading the word about this great company. Thank you so much Semper Solaris for the great experience.

Great experience with this company! I would give them more than 5 stars if I could. I appreciated their work so much because I was getting solar panels installed for my mother and there had so much patience and kindness towards her when explaining what was going to happen and what they were going to do as far as the installation. Very friendly people and will most definitely be sharing my experience with them with anyone looking for solar panel needs. I m so impressed with their professionalism and time management for their projects I was expecting the worst from them since I 've had several previous bad experiences with other companies and Semper Solaris really changed my mind as soon as I spoke to them. Thank you Semper.

Loved their work, absolutely amazing service. Made me feel like I was giving them the moneys worth for the job. It was my first time wanting solar panels and after many issues with other companies and their customer service, I found Semper Solaris! They made it so quick and easy to find me a good priced solution. Very friendly and a veteran friendly company. Definitely would recommend to anyone looking for solar panels, roofing needs, or even a solar battery storage system so that you can save even more on electricity bills! Semper Solaris does it all, and best of all they have such great prices that not many companies can beat. 5 stars all the way!! Thank you for such an amazing experience.
