I had gotten many quotes for a solar system in the past and have know of OC Solar when they first…read moreintroduced me the solar roof. While the solar roof was way out of our budget, the solar panel and powerwall system that they've configured for me was well beyond what I expected and was well within reasonable cost. Sun Run was out of the question, and even Tesla themselves weren't able to meet the final project demands when they first designed my system. OC Solar was the only who actually met my needs and were on top of the whole project timeline. Look no further than these guys. They did a wonderful job and would go to them in the future for my other solar needs. Ask for Brooklynn and she'll take care of you, without a doubt.

I do not normally leave negative reviews, but after nearly 10 years, I feel it is important to…read moreshare my experience. Before posting this review, I made every reasonable effort to resolve these issues directly with the company. I sent a formal letter over a year and a half ago outlining my concerns and requesting assistance, but I never received a response. More recently, I sent another detailed email, giving the company 14 days to respond with a plan to address these longstanding issues. That deadline has now passed, and once again, I received no response. This company installed my solar system in 2016. At the time of purchase, I was given expectations regarding the amount of energy the system would produce and the savings it would provide. Unfortunately, those expectations have never been met. In nearly ten years, my system has never produced the level of solar energy that was represented when I made this investment. As a result, I have spent thousands of dollars out of pocket on Southern California Edison bills that I reasonably expected my solar system would significantly reduce. Instead of receiving the savings I was promised, I have continued paying far more for electricity than I ever anticipated. What has been most disappointing is the lack of follow-through. The company has been aware of issues with my system for years, yet they remain unresolved. Despite numerous phone calls and emails over the years, I have received little to no communication, no meaningful updates, and no proactive effort to correct the ongoing problems. There were also issues from the very beginning. When my system was installed in 2016, I was never provided with the monitoring equipment that was supposed to come with it, nor was I informed that there was a monitoring app available. Without those tools, I had no way of monitoring my system's production or knowing that it was consistently underperforming. After years of phone calls and emails to the corporate office, I finally got someone to come out in 2023 to install the monitoring equipment that should have been installed from the beginning. It was only then that I learned there was an app that allowed me to monitor my system. During that same visit, the technician determined that my microinverters needed to be replaced. The replacement microinverters were shipped to my home, and the technician returned to pick them up for installation. However, the work was never completed. The technician left with the new equipment and never returned to finish the job. Despite additional attempts to follow up, I was once again left without answers or a resolution. I understand that mistakes happen and that every company occasionally encounters challenges. However, this is no longer a matter of a simple mistake or a temporary inconvenience. This has been an unresolved issue for nearly a decade. My goal has never been to leave a negative review. My goal has always been to have the solar system I paid for perform as it was represented and to have the company stand behind its product and installation. Unfortunately, after almost ten years, thousands of dollars in unexpected utility costs, years of unanswered phone calls and emails, an incomplete repair, and two formal written requests that went unanswered, I have been left with no meaningful communication and no resolution. I sincerely hope this review encourages the company to finally contact me, complete the repairs that should have been completed years ago, thoroughly evaluate my system, determine why it has consistently failed to meet the promised production, and stand behind the product they sold me. If the company reaches out with a genuine commitment to resolving these issues, I will gladly update this review to reflect that experience. I would much rather write about a company that ultimately made things right than one that chose not to.

Best thing is that his business does it all, making it convenient and integrated. I had to do some electrical work (in a couple of stages - new panel, as well as new trench as the panels are on a detached garage), and also some roofing work, as well as installing the panels themselves. Instead of having to talk to, get bids from, and coordinate work separtely from roofers, electricians and the solar installer, William took care of it all. AND it was the most competitive price of all the bids I got from solar installers. His crew was enjoyable to have around - literally, they would notice and enjoy the birds singing - and it made it all even better. We are very satisfied with the system. And we've had questions afterwards, and William has been extremely responsive in addressing any issues. I wholeheartedly recommend considering Sigway and William for your solar needs. Qualified, experienced, ethical, thorough, and easy to deal with.

The workers are very friendly and explained what they were doing as I went out there peeking at what they were working on.
