I had my solar panels installed back in December 2021, And I’m happy that Roland recommended me to install a 5.65 KW solar system.Today, after 4years, Roland came to visit me to update me on the new regulations in the solar panel industry. How SDG&E is changing the billing regulations. I’m glad that I had installed my system back in 2021, as I’m grandfathered in to the 2.0 model. Hence I am saving quite a lot of money every year thanks to Roland.I want to emphasize that the job Semper Solaris did on the installation was very professional. As you can see from the pictures I have attached., the electrical conduit that went from the electrical panel to the roof did not loop around the rain gutters, which I found rather eye soaring on many homes in my Community. The exterior of my house looked really clean.In the case where I might purchase an EV vehicle in the future, Roland said that a Battery might not be the best solution in my case.Hence if anybody is looking to install a solar panel system or a battery, you should consult with Roland to determine the most efficient and advantageous system to be installed in your home.Thank you again, Roland for your professional advice and service.
I decided to go solar with semper Solaris initially because of Sue Champagne who was so informative and gained our trust. She was knowledgeable and professional. I'm thrilled now that its up and running. The crew did a fantastic job and were super clean and made it a painless experience. Hard to do in construction. Extra cudos to Ruben who was fantastic
I recently purchased a Tesla power wall. The installation team from Semper Solaris (led by Sebastian) was great! The guys were professional, friendly, and knowledgeable! They respected my property and did an excellent job on the installation. They helped me think through some changes to the plan and what would be best for my home. I can’t recommend them highly enough!
Semper Solaris kept the work area neat and cleaned up well upon departure, Roland was my energy consultant and answered all my questions I had and provided great customer service, the whole team was efficient and quick. I would definitely recommend this team as they are positioned to be around a long time for their customers. I see they do windows now and all other home energy products. I'll be sure to contact them when my HVAC goes out.
Our installer, Sebastian and his team were excellent, super communication and instructions with regards to our battery storage and the subpanel and the array that was placed on the roof.Always arrived on time. Great job.They will do our roof next.
