Based on my experience with Neosun, this is a job well done from start to finish. Nare monitored the project closely and coordinated with me on its progress every step of the way. Nare's team of workers were professionals - installation was appeared clean, looked good, and they were courteous, accommodated my questions, and did their jobs well. Following the installation were days of heavy rains and it was good to learn that i did not experience any roof leaks. This is a no BS, no nonsence solar company providing fair prices and quality service. I highly recommend this company for your solar needs.

I really appreciate the direct accountability and quick resolution. I'm leaving my original review below for transparency, but their prompt response today restored my confidence in their management. I originally had a positive experience with California Solar Electric during my 10.12 kW solar and Powerwall 3 installation last year. Unfortunately, their post-install customer support and business ethics are nonexistent. I referred a friend who completed their installation months ago. I was explicitly promised a $500 referral bonus for this. After months of waiting, I tried following up multiple times privately to give them a chance to make it right, but I am now being completely ignored. It's a shame because I have several neighbors here in Fountain Valley who are currently shopping around for solar and battery storage. I was planning to refer them here, but I cannot recommend a company that fails to honor its own written agreements and ducks communication. Buyer beware: the installation team does good work, but do not trust a word management says about referral incentives or post-sale promises. Still waiting for my $500.

I'd highly recommend Solar Optimum and Roofing Optimum…read more We've had our solar system from Solar Optimum for more than 10 years, and our experience is a great example of why choosing the right company from the beginning matters. They installed a high-quality system that has performed extremely well over the years. At one point, both of our inverters experienced a manufacturer-related issue. In fact, Solar Optimum identified the problem before we even realized something was wrong. They worked directly with the manufacturer to secure a replacement inverter at no cost and handled the installation quickly and professionally. When it came time to replace our roof, we didn't hesitate to reach out to Solar Optimum again. Their GAF Master Elite certification and the advantages of having the same company manage both the solar and roofing work provided tremendous peace of mind. The warranty benefits are excellent, and the roofing warranty is transferable, which adds real value and is something many roofing companies do not offer. We recently completed a full solar removal, reroof, and solar reinstallation project with the Optimum team, and we couldn't be happier with the outcome. The entire project was completed in about a week, exactly in line with the schedule that was provided at the start. The crews showed up on time, worked hard, communicated well, and cleaned up thoroughly at the end of each day despite the significant amount of work involved. From start to finish, the process was smooth, professional, and well-managed. It's rare to find a company that delivers this level of service over a relationship spanning more than a decade. We couldn't be more pleased and highly recommend Solar Optimum and Roofing Optimum.

After speaking with several of them at length and getting a number of quotes I came away with the feeling that many of the people I was speaking to (often a salesperson) were trying to rush me into a sale and/or were not that knowledgeable about the products and subject matter I had questions about. I immediately had a much better experience with OneSun. The business owner, Rose, was great about helping inform me about the process and honestly answering all of my questions over a number of phone calls. It helped us feel confident that OneSun would attend to any issues before, during, or after the installation.

Our battery has stopped charging, inverter has an error and it stopped producing by about 50%. It's difficult to get a hold of anyone quickly but Tony reached back out a day later for an appt with a tech and fox rep 2 days away. The tech did not turn up. fox and myself couldn't get a hold of anyone for 2 hours while we are waiting for info on why they aren't here. Fox found installation mistakes and helped identify the issue even though they aren't supposed to touch the installation, 2 panels shorted out and I need first American to fix it. The tech made some excuses for not turning up, said they had turned up at a different time for some reason, although my cameras don't show anyone at that time either. It's now been a week and no one will provide me with a day or time for an appointment. They outsource the techs, they do not work for first American. Im left with a system that won't charge, producing 1/3 of the output and im left holding the bag with a company that won't provide support service, you pay the money and then you aren't a priority when it doesn't work. Zero priority even when they missed the appointment. Tony's been answering the phone so he's the only one I can put a good word in for but there's no service reliability from First American after the fact. I'll update this review with the eventual outcome.
