However,…read moreit's still about 4.8% below the minimum guaranteed production (accounting 0.25% maximum annual panel degradation). It's 4 year in a row now the system failed to produce the minimum guaranteed production. AWS Solar chose to compensate for the shortfall again; we'll see what the 5th year production looks like. I suggested replacing some of the panels with the higher power ones to solve the issue, but I guess they want to see more data.

Within an hour of posting my initial review regarding a delayed referral bonus, the owner…read morepersonally reached out, apologized for the administrative oversight, and sent the $500 immediately. 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.

TL;DR: Rose is incredible. Honest, patient, actually knows solar and is not just a salesperson. She…read morewill answer every single question you may have and follows up. 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!

Alan and the team at Solar Wholesale Group have been fantastic…read more They installed the solar system on our home over 10 years ago, and during a recent 400-amp electrical panel upgrade, they really came through for us. They were always available to answer questions, troubleshoot issues, and coordinate with our electricians whenever something came up. Because they knew our system inside and out, they were able to jump in quickly and help keep the project on track. Having that history with our home made a huge difference, and their professionalism and responsiveness took a lot of stress out of what was otherwise a complicated project -- all without having to break the bank. They are extremely fair with their pricing. It's one thing to do a good installation, but it's another to still be supporting your customers more than a decade later. That kind of long-term service is hard to find these days, and I'm incredibly grateful for everything Alan and Solar Wholesale Group have done for us. Highly recommend.
