George showed up at 1:30pm & switched out the old inverter for the new one. Everything is working great like it used to! Ivan, Scott & Jayson have been in constant contact with me about the progress of getting Tesla to ok the work. So grateful for their dedication! I definitely recommend Option One Solar! Update. To be clear I have nothing negative to say about Option One Solar, at the time I was disappointed with the outcome that seemed that I was out of luck. Scott & Ivan have been working on resolving this issue that is on Tesla's end & have been keeping me in the loop. They both have been communicating with me on the progress of my work order. I really appreciate their dedication to getting things done & finding a resolution to this issue. I will update again after this is done.

This experience was exceptional! The company that installed my system has gone bankrupt so Tesla…read moredirected me to its trusted installers in the area. I picked Option one right at the top. Natasha was professional and very clear with communication from the start. She set proper expectations on communication with Tesla would take a week or two. The day she received the go ahead from Tesla she called and scheduled the install asap 4 days out. Later the same day they had a cancellation and were able to get everything scheduled the next day. Anthony and Jeremiah arrived at the beginning of the arrival window! They were professional, great with communication, and ready to work. I had several questions and they were prepared for all of them and super helpful. The battery removal and install took less than an hour. Naturally Tesla's update took twice as long. LOL. Still total time was under 3 hours. I have managed 100s of installers and worked in Solar, this was a fantastic expierence! Because the Tesla 3 has more storage than the 2 I asked about adding some of my Breakers to the back-up and they had options for us to do that. Obviously we Highly Recommend This Team!

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.

I definitely recommend Sigway Energy for your solar installation.
