"I’m so excited today. Baker Electric is completing the installation of my Tesla battery which will connect to my solar system. The entire process has been seamless. From the very beginning I received informative emails from the office keeping me up to date about required permits, process needs and what to expect next. As luck would have it, I also received a call that the workers could come to my home a day earlier than I was promised and they asked if I wanted them to start early! I knew when to anticipate their arrival and what they would need to get started on the project. Before the workers began the installation of my battery, they reviewed what the two-day process would look like and when to expect my electricity to be turned off. As they worked, they kept the work area clean, reminding me where they were in the process, and when the electricity would be off. No matter how many questions I asked, they acted like responding to me was a priority and didn’t walk away unti"

"Semper Solaris Battery Installation Review I hired Semper Solaris to design and install a battery system tailored to my home?s needs, and I provided them with all necessary data upfront. Unfortunately, their proposed solution was not engineered appropriately and failed to meet expectations (I found out afterwards, since I am a Radio/Radar engineer, not a solar power engineer). The installation designers wanted to place the batteries in an unsuitable/ridiculous location and used a system that unnecessarily rewired my power panels, creating significant electrical complications. (As an electrical engineer, I recognized these choices as poor practice). After installation, I had to resolve account and software issues directly with Tesla, only to learn that the system had been improperly sized. Semper Solaris did not deliver the professional expertise I relied on. "

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again. "

"i could not be happier with OC Solar, they deserve all of the hype! i have worked with vinnie and the oc solar team for over 5 years and done many projects with their team. they are always on time, priced well, easy to work with, and the communication is excellent. itâ s hard to find good contractors, so when you find one, you have to tell people, and OC Solar is worth putting my name on the line for. we have had them install Tesla power walls for us, specifically the tesla power wall 3. they have installed panasonic and q cell panels for us and the installation quality is top of the line. highly recommend, 10/10. choose ur installer wisely, los angeles is not easy to work with, so i recommend a proven company like OC Solar"
