    This was a great company to work with. Daniel and Sherry were very responsive and the quality of the Sheffield install was top notch. Highly recommend!

    5 Stars - Quality Work and Excellent Support from Start to Finish We recently had our roof and rain gutters redone by DLS Development, and the experience was excellent all around. Our initial inspector, Mike, was friendly, knowledgeable, and gave us a clear understanding of our options. Sherry, our project manager, was incredibly helpful and responsive throughout the process. She always made herself available for our questions and promptly addressed any concerns that came up. At one point during the gutter installation, one of the workers had nailed into a few shingles while installing the micro mesh gutter guards. We brought it up to Sherry, and DLS immediately took action -- they sent Daniel, another project manager, along with their roofer to inspect and fix the issue. They replaced the affected shingles and had their gutter team correct the installation. It was handled quickly and professionally, which gave us a lot of confidence in their commitment to quality. The communication was solid, timeliness was good, and both the materials and workmanship were top-notch. DLS also matched prices and made sure we felt we were getting great value for our project. Being Owens Corning Preferred Contractors, we also know our roof is backed by a strong warranty and built with reliable materials. If you're doing your research (as you should), make sure DLS is on your list of bids. They use quality products, stand by their work, and have a great team supporting the process from start to finish. And if this review helped you decide -- tell them Megan and Miguel referred you!

    Great company to work with! They gave me the lowest quote with best reviews and certification out of 5 bids I received. The entire process was smooth and very professional, and I have a new roof in three days and it looks great! Highly recommend!

    DLS Development did an incredible job on my dad's roof in Reseda! The entire process was seamless, and Sherry, the project manager, was both personable and professional every step of the way. She made sure everything ran smoothly, and to our surprise, the work was completed two days ahead of schedule! The roof looks fantastic, and we couldn't be happier with the results. Highly, highly recommend DLS Development to anyone looking for top-notch roofing work!best value for your $

Their quote, plus their high reviews made them the logical choice, and we have no regrets. From the person who did the site inspection, Jose, to the installers, everyone seemed very friendly, respectful of our property/wishes, and it was clear they were experienced and knew what they were doing. Being up against a deadline, we really couldn't afford to fail the city inspection, and we passed easily. Thanks to the salesman Mark Howe for his direction, & to Henry Melling for a great design and implementation. We were not excited at the idea of having all that stuff on the side of our house, but honestly, the installation was so neatly done, with a few plants added over there, I'm sure we can acclimate. The battery placement in the garage was genius -- up and out of our way! Everything is functioning as it should, and we wouldn't hesitate to recommend California Solar & Electric. THANKS to them for a job well done, and ON TIME!! We couldn't be happier.

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!

    We hired this company based on a recommendation from our roofing contractor's project manager, but…read moreunfortunately, they did not live up to that recommendation or the positive reviews we saw online. The scope of work was the removal and reinstallation of our existing solar panel system during a roof replacement. Estimate: Fair pricing. Communication: Quite lacking. It felt like we always had to be the ones initiating contact, even when it came time for them to collect their payment. Service and Workmanship: The removal took one day and the reinstallation took another. We didn't have any issues with the removal, but the reinstallation had several major flaws. Most notably, they reused the original flashings, which were bent and warped. Because of this, our brand-new shingles could be subjected to warping. We pointed out a few visibly damaged flashings at the corners, but we have no way of knowing the condition of the flashings hidden beneath the panels. Considering we just spent $20,000 on a new roof, they really should have asked if we wanted to replace the old flashings with new ones. Now, I am just hoping we don't end up with leaks in a few years. Cleanup: The second major problem was their lack of professionalism at the end of the job. When they finished, they simply walked off. They didn't clean up or pick up their trash, leaving debris all over the roof, roof gutter, and throughout the yard. Overall: I absolutely would not have hired this contractor if I had known how poor the workmanship and customer service would be.

A huge investment for our home along with a relationship with an energy company that will bring cost savings in our golden years when life changes bring fixed incomes and ways to save in order to survive the day to day living in California- hey it's tough out there! Especially as you get older and you want to stay in your home. 10 years ago we choose L A Solar Group to design and install a solar system that would fit our needs on our existing home they were very receptive to our desires on keeping the panels on the back side of our home so the panels would not be visible from the street or the front of our home. They came up with a design that worked without compromising efficiency. Within 3 years we paid off our initial costs to purchase our equipment by not having to pay the high energy fees Edison was charging us to power our home all year long. L A Solar Group designed a system that energizes our home, charges our Tesla Battery Wall and feeds energy back to the grid. Saving us money each year with a design and equipment featuring state of the art products has been a life saver for us and has paid off in the long run. We had a few hick ups during post installation from wear and tear items which L A Solar Group staff and technicians were quick to respond and get us back up and running. From start to finish, design to installation and customer interface to maintenance L A Solar Group has been our partner in the energy field. If you are in the market for Solar and you want a name you can trust, a partner in energy supply and a staff that is available to help in any way this is who you should be contacting for your Solar needs. Well done L A Solar Group, Bravissimo!

    Loved working with Sol Volta and would choose them again in a heartbeat…read more I had received almost 20 bids, but practically every company I spoke with produced a quote by looking at my property on Google Earth, as opposed to visiting my home in-person to get a realistic idea of what we were working with. I have a flat roof and a small amount of space to work with. It's further complicated by the presence of a AC/heat pump package unit, and there are taller homes/objects around my property that cast shadows. A majority of the folks at other companies I spoke with were in sales, solely interested in selling me on more panels without taking into account city code, setback limitations, environment around my home, etc. Gabriel was the only person to show-up on site. It was a huge relief that the person who was giving me a bid was also the engineer installing the setup. He suggested tilting the panels so I could optimize the amount of solar my home generated, completely offsetting my utility bill with room to spare so I can add an EV next year. While Sol Volta was not the cheapest bid I received, my preference is to get it right the first time, even if that includes spending a bit more upfront. With Gabriel and Sol Volta, I felt like I was in good hands. I had originally planned to add a battery solution later in the future (given it adds significant cost) but I liked Gabriel and Sol Volta so much that I decided to do it now and we went with a Powerwall 3 - it's awesome. Cannot recommend these folks enough - they're professional, incredibly knowledgeable, and kept me in the loop at all times. Thank you, Sol Volta!
