Has a professional installation crew and executes flawlessly and everything stays on track. Incredible follow-up and will not try to upsell you like other installers. If you're looking to install solar, you should absolutely go with OneSun. Give Rose a call to at least get a consultation and I'm sure your interaction will immediately stand out from other installers. Installing solar is something I kept putting off. When I found out that the tax credit would be going away at the end of 2025, I realized I couldn't put it off any longer. One of the reasons I kept waiting was how annoying solar reps were. Clearly just sales guys who didn't actually know anything about the equipment, technology, and process. I did a bit of research on local installers and OneSun came up a few times, all with nothing but great things to say and especially highlighted the installer's knowledge and patience. Before reaching out to OneSun, I informed myself as much as I could to the point that I knew what panels I wanted, size system, even what inverters I wanted installed. My first phone call with Rose immediately proved that all of the positive feedback I had read was for a reason. She took the time to actually listen to the specifics of my project, what I was looking for, and what questions I still had based on my research. She took the time to answer every question and even went into the technical details that I was interested in. It was clear that she was extremely familiar with not just the logistics, but also exactly how a solar system works as well as the technical details of all of the components in a system. She had my business after that first meeting but of course I still did my due diligence and got a quote from one other local installer which also had similar reviews. Although the sales rep was very nice, it was clear that he was just a sales rep and only reinforced why OneSun was the installer to go with. OneSun's pricing happened to be better but even if the other installer would have come in at a cheaper quote, I would have still chosen OneSun for the install. Rose started the permit process in July and made sure that everything stayed on track, especially since I wanted to make sure that the system be on before the end of the year in order to qualify for the tax credit. The timelines she provided were right on point and the install was scheduled for September. About a week before the install date, there was an unexpected problem. The panels that were originally planned for my install had gone completely out of stock. There had been some kind of manufacturing issue and those panel would not be coming back in stock for another couple of months which could push the project out to the following year. Rose let me know she could acquire slightly larger panels for the project and install it on schedule. I was about to ask what the additional cost for the larger panels would be, but before I was able to, she let me know that there would be no additional cost to me. I'm sure any other installer would have used the situation as leverage to add additional cost to the project. A testament to Rose's commitment to her customers. On installation day, the crew was professional and efficient. They completed everything in one day and made sure to keep everything as clean and organized as possible. Towards the end of the install, I had noticed that they ran one of the grounding wires out from the attic and down the face of the house where I had planned on completing another project in the near future. I knew that the wire would need to be redirected if it was left there so I asked the foreman if he could run it through a different path. Initially he felt like it would not be possible given the layout. I reached out to Rose just to make sure and see if she possibly had another solution. About 10 minutes later the foreman showed me another possible option which was much better for what I needed. It may have seemed like a small thing, but that was another instance in which I believe any other installer would have dismissed my request as pickiness and told me there was nothing else they could do. Rose took the time to speak with her foreman and truly assessed the situation to come up with a solution that fit my needs. It took LADWP about 6 weeks to get my meter installed and for my system to be turned on, but it was still well before the end of the year (and yes, I just got my tax refund with that hefty solar tax credit). It's rare to come across someone like Rose who is honest, patient, and who truly has her customer's best interest at heart. Combine that with impeccable execution and communication, and there is no one else I would recommend for a solar install project. In fact, my parents are considering a small project and I've already told them about Rose/OneSun.

When I first contemplated getting solar panels for our house, the entire process looked daunting. I…read moredidn't know anything about the technology or equipment and I felt ill prepared to make any decisions about what our house needed. There are so many companies out there, it's hard to know who to trust. As soon as I did a few online searches, I was flooded with emails and texts from multiple companies with high pressure sales pitches. One company charged me $350 to do a site survey, just to get a quote for the project, then came back with a revised quote adding $7000 to dig a trench for electrical wiring due to "the location" of our electrical panel. I found OneSun on a yelp search and as soon as I spoke with Rose Avakian, I knew my search was over. This company stands out from the others. There was no sales pitch, pressure, or upsell. Rose explained the technology and equipment in a way that made it understandable and approachable. When her team came to look at our place, they found no need to dig a trench and simply connected to our existing electrical panel. Had they needed to dig a trench, the price they quoted was nowhere near $7000.  From start to finish, the entire experience was transparent, seamless, professional and expedient. The attention to detail and care the team put into making sure everything was done right far exceeded my expectations. If you're looking to go solar, look no further than Rose and OneSun. This is truly the best company I've ever worked with!

It has been about 8 months since the project was completed so I feel I can write this review fairly…read moreabout my experience. It was pushed to get it in before the credits ended. For the quick summary, there was a mistake in my installation, it was not handled well and the system works well but only after a long struggle. They price match but hard to say if I felt good about the price in the end either. Overall, it is very mediocre. After talking to 4 companies, I decided to go with OC after they honored a price match from a competitor. It was a fairly large system, 15 panels and a Tesla power wall 3 and needed to be added to existing system as my current one was underpowered and required due to new builds in California. Total was about 33k, out the door. It may not have been the cheapest offering but shopping for solar is not my favorite experience and I went with what I felt was at least fair for what I got. I primarily worked with Don from sales and Brooklynn and initially seemed fine and for all intents and purposes, it should have been. I chose to get HOA approval and pay for it myself so it did stall the project through no fault of OC. My HOA requires applications for major projects to be submitted along with a sizable fee, and I chose to do it by the book. I dropped the first major deposit of 10k and the installation was scheduled around July 2025. The next part is where the struggle began. The day of installation, the installers tell me the panels cannot fit in the design that they were given. They asked if I wanted to pivot to another part of roof and just install it then and there. I call OC and they admit the design cannot possibly fit my panels on this small area of my roof and I cancel the project and have them redo the plans and for me to go through HOA again. This leads to a very frustrating back and forth with Don and later Brookylnn's superiors as I no longer heard from her. I had about 10 calls or more trying to clarify what to do next and was met with a lot of resistance about what happened. It turns out the plan was actually the original estimate from Don (sales) and for some reason just pushed through their architectural team without consideration of the size. Don's superior Chandler even spoke with me about this and though I can't recall their explanation for this mistake, they spoke as if this was my issue with wanted to go through HOA and that they had no power to stop the project. If I had written this review after this call, I'd recommend no one work with these people. It felt frustrating and at times demeaning, given that they do this all day and I don't know what I'm talking about. After I got my second approval, OC refunded my fee to the HOA approval, but only after I explicitly asked for it. We eventually moved forward with the project and inspection when fine. My guess is had we not had this irresponsible prelimary design provided by Don go through their "architectural" team it would've been fine and none the wiser. As of this writing, the panels are working as intended and I had such a sour experience, I just moved on. But now Don and company requested a review for their internal systems, so here is it and a Yelp one that they did not ask for. In the end, like most of these experiences, it's not the mistake that upsets me, it's the handling of it. Communication started fading when things got more difficult and the lack of empathy or consideration for some dropping this much money on something they will do maybe 2-3 times in their life is disappointing. Much of the time I asked them and myself, how should I know this plan wouldn't work? Sure the HOA can't legally stop me, but I have to live with them, not OC. Whoever may have gotten this far, thank you for hearing my rant. Odds are you will have a fair experience but the truth is, most of these companies are interchangeable. They are all middle men and their strength and differences lie in the customer service and coordination. I didn't expect but solar buying is probably more similar to going to a car dealership. Do your research, advocate for yourself and don't get your hopes too high and it will probably be fine. As for OC, I think in the end they are just mediocre. They're like anyone else you may talk to. The processes are probably similar and I'm glad the system has worked well, which helps my scoring of this review. Maybe they just got lucky with me at the time, as I was getting fed up talking from one salesperson to the next and they price matched. I'm sure others will and can do the same so whoever you go with, as long as you are on top of it, it will go fine.
