Adnan Sidd | Los Angeles, California | 09/18/2025

Very happy with our experience with OneSun. They installed a 6 kW Enphase system on our roof. The entire process -- from initially requesting a quote to our first day of power generation --- was about 6 weeks (some of which was waiting for the city to issue permit and for LADWP to install a bi-directional meter.) We also took care of some roof repairs which added some time. The installation itself took 1 day. Monitoring our solar production and energy consumption through the Enphase app is super cool. Rose walked us through the whole process and was extremely knowledgeable. Pricing was transparent and honest, and we felt no sales pressure from any kind of upselling. Rose was super responsive anytime we had questions. Glad we went with OneSun!

I found out about OneSun through a Reddit post. I also looked into their reviews. Everyone highly spoke of them. When my wife and I first spoke to Rose in person we really appreciated that she was very knowledgeable and able to answer our many questions. We also appreciated that she was not pushy in trying to sell the service. Working with Rose throughout the whole process was very smooth. She was very communicative before we bought solar, during the installation, and after installation. We are also very happy we got solar panels and it was with OneSun. Rose was honest and upfront about the whole process.

I was interested in installing solar for my house and found the only stressful part of it was finding the right company. Thanks to Rose at OneSun, the rest of the experience was completely stress-free. Not only did we get the best value for the best equipment on the market (I did tons of my own research and consulted a family friend in the industry), but Rose was so great at walking me through all the steps and demystifying the whole process. If you’re in LA and considering getting solar because you want to save money, consider saving yourself time and stress by choosing OneSun. I promise you won’t be disappointed.

OneSun was extremely helpful in getting my solar panels installed! Rose was able to answer any questions that I had thoroughly and quickly. Rose also helped me through the full process from start to finish. I couldn’t be more happy with how the process went for getting solar panels! The price was better than what I had seen out there from other companies as well!

I recently had the pleasure of working with Solar One Company to install a solar energy system for my home, and the experience exceeded all expectations. From the initial consultation to the final installation, their team was knowledgeable, professional, and incredibly responsive. The sales representative and owner, Rose Avakian,took the time to explain everything clearly and answered all my questions without any pressure. The installation crew was punctual, efficient, and left everything clean and tidy. Most importantly, the system is performing exactly as promised, and I’ve already noticed a significant drop in my energy bills. What sets Solar One apart is their genuine commitment to customer satisfaction and sustainability. They walked me through every step of the process and even followed up after the installation to ensure everything was running smoothly. If you’re considering making the switch to solar, I highly recommend Solar One Company. They deliver quality work, excellent service, and real results and mostly stress free permits.

Excellent all around

I had an incredible experience working with Rose from our first contact through to my solar panels up and running. She is knowledgeable, reliable, impeccably honest, and a kind person. She communicated with me throughout the process so that I exactly what to expect. Any wait times beyond the schedule she set were from waiting for the city, and she kept in communication with them and with me to try to estimate how long those waits would be. I never felt pressured by sales tactics, Rose just shared detailed information with me and let me make my decisions. I spoke with a few other companies and this wasn’t always the case. I’m VERY happy with my new system, and so glad I made the choice to work with OneSun!

Great Company and Experience

I was very impressed with OneSun’s professionalism and clarity throughout the process. From the owner Rose explaining every aspect of the agreement and walking me through the product specs to the professionalism of the installation team, they made the entire experience worthwhile. We are thrilled to finally have solar and to watch our “net export” figure grow each week. Highly recommend!

Selecting the right company for Solar Installations

Review of OneSun Personal rating - 10 stars Guided by personal research there was one apparent big advantage to hiring a local company who offered a designated personal project coordinator to conduct all the necessary stages of installation and operation. Of primary importance a review of electric bills directed the preparation of planning how many panels are needed, compliance with LA DWP to ensure compliance with regulations and connection to the grid for credit. One such company offering this level of service after extensive review was “OneSun” located in North Hollywood servicing Southern California. Initial contact resulted in a personal at home consultation with Rose Avakian, whom I found to be a great regular communicator. This lady demonstrated her knowledge and experience instilling complete confidence that I had indeed selecting the right company for the job. After site surveys, planning, building and roof safety approvals, installation began promptly with a highly coordinated team of profession engineers and electricians - essentially a 1-2 day project. Final inspection and approval to operate from LA DWP did take a few weeks. Then the electric bills dropped to $40.00 a month! Overall embarking on installation of solar panels to reduce my electric bill was not daunting, but Rose Avakian and OneSun made the process stress free without the cumbersome paperwork required by regulatory authorities. Conclusion - strongly consider calling Rose Avakian to start your journey to energy self-sufficiency for the future as cost of energy has been predicted to increase drastically. The whole process was professional perfect thanks to this team approach with a Project Leader! Well done, Rose! Thomas Cairns, Studio City, installed June 2024, approved July 2024

OneSun -- one word, amazing!

To anyone looking for the very best solar company in Southern California, you must give Rose at OneSun a call! My wife and I were really interested in installing solar at our home for both energy efficiency and environmental reasons, and within minutes of reaching out to OneSun, Rose was already reaching out to us and helping answer initial questions. Rose walked us through the entire process, giving us several different quotes with different array options -- and never once did we feel any pressure. Instead, we felt completely comfortable and that we were in the right hands with OneSun. We ended up deciding on a system at a great value that gives us an 85% energy off-set as well as the option to expand the system in the future. The process was incredibly smooth! From the installation to the follow-ups, everything was handled with extreme professionalism. Our neighbors walked up to us a few days after our installation, and asked who came out to install the panels, and we told them -- OneSun!
