Project: Install Solar Panels For Electric System
The entire process was seamless and it was very easy to work with Bob King. The monitoring is easy to use and informative. I could not be happier with the performance of my system. Went from $700/mo in summer with AC on daily to $10/Mo... I'm AMAZED and so thankful for Bob King and Semper Solaris!

We are very pleased with Semper Solaris and even more with our consultant Caesar. He really did an excellent job answering every question we had and was not pushy on making a sale. Our Solar install ran so smoothly and the whole team was very professional and very helpful during the entire process. Thank you Caesar and the entire team at Semper Solaris! I will be referring family and friends for sure. I highly recommend!

I highly recommend Kurt V. at Semper Solaris. He went above and beyond from start to finish and made the whole process easy. He was spot on in determining the amount of panels we would need to break even on our electric bills. Great job, Kurt!

Semper Solaris helped me get solar for my house. I had a lot of questions, but I felt Caesar answered them best for me, and he even told me things than no-one else had. Price was good and it made sense. Still, I'm skeptical so I was still worried how the process would be. You know, after everything, I didn't really do much and everything turned out great. Thank you guys for doing a great job. Looking back now, I wish I had done it sooner. Nestor M.

I bought a roof and solar panels from Semper Solaris because I really felt that they would take care of me, but I never really expect things to go without a hitch. So I gotta give credit where credit is due. All the guys were great, from Caesar to the rest of the crew. There's a lot of horror stories out there about solar, but I definitely would recommend Semper. Thank you guys.

Review by in Los Angeles, CA
I've had 3 other companies come talk to me, but I know so much more about solar and how it works and how it will work for me from Caesar L.'s presentation than anyone else. He was incredibly helpful and answered all of my questions. He showed me all my choices with purchasing and leasing the solar system. Everyone should have the opportunity to sit down with someone who actually helps.

Review by in Simi Valley, CA
When we moved into our new house, we knew we wanted solar. Brandon, estimated our likely usage and set us up with 20 panels in the hopes of offsetting 100% of our electric bill. Well, we just finished our first HOT summer and we are as pleased as ever! We ran our air conditioning non-stop from July-September and not only did our panels cover 100% of our usage, but it looks like we will be getting a check from Edison at the end of the year. It took probably about 2 months from the signing of our contract to the installation of our system. Semper installed our system quickly, and without any issues. Initially, right after installation, I noticed some silver conduit running along the side of a portion of our house. It wasn't awful or anything, but... when I told Brandon about it, Semper sent guys out right away to paint it to match the color of the house, so now it blends in perfectly. I cannot say enough good things about solar in general, and Semper. Thanks guys!

Review by in Sonoma, CA
Wanted the best panels with the best company. Only talked with companies that carried Premium panels. The easiest choice was Semper Solaris and Brian O. The ratings of this company across California is amazing. Brian taught us a lot about Solar and the Semper Solaris way. He helped connect all the dots and crossed all the T's for us. If you want a patient and trustworthy company, call Semper Solaris and ask for Brian O. today!

Been thinking about solar for 3 years and finally made the decision to go for it. Met with 5 solar companies and liked Brian O. with Semper Solaris the most. He is very knowledgeable and saved us thousands of dollars from our best bid. I love to save money. The process from the beginning to the end was so simple and easy. Wouldn't have had it anyother way. We recommend this company to everyone.
