The Verdict
OneSun earned our strongest recommendation after we analyzed nearly a hundred reviews. We found zero complaints about workmanship, zero complaints about sales conduct, and zero complaints about follow-up support. One homeowner met with Rose after backing out of a 25-year SunRun lease trap, relieved to finally talk to someone who spoke plainly about costs instead of burying everything in financing jargon. Another watched the crew color-match exterior paint to hide new conduit runs without being asked. The communication pattern stands out most: 68 reviews praised project management, and Rose personally handled permit wrangling with LADWP so customers didn't spend weeks wondering when the city would show up. She answered the same questions dozens of times without losing patience, walked customers through system monitoring apps after installation, and even flew a drone to photograph finished roof work. The process moved fast once permits cleared (most installations finished in one or two days), and several homeowners reported negative electric bills within nine months. If you've talked to pushy solar reps who couldn't explain why one inverter costs more than another, Rose will feel like an old friend who actually knows the answer.
If you want a solar installer who'll color-match your stucco without prompting and chase down LADWP on your behalf, OneSun is worth the call. The quote may not be the absolute lowest, but you won't spend months in permit limbo or discover surprise costs after signing.
Reviews That Shaped Our Verdict
Mary had been fielding door-to-door solar offers for years and, after hearing horror stories from neighbors and friends, finally decided to pull the trigger and find a company with a solid process. She found OneSun on Reddit and chose them because the feedback felt reliable. A rep named Rose came out, walked through the whole plan, answered technical and legal questions, and put them at ease. After the panels went up, Rose didn’t disappear — she pushed LADWP to schedule the meter swap quickly, and when the family was out of town she even called the utility to confirm how crews could access the backyard. Rose stayed in touch through the final steps to make sure everything was completed correctly. OneSun wasn’t the cheapest bid, but it landed in the same ballpark as the others, and the hands-on follow-through with the utility made the extra cost feel justified. The detail that lingered most was Rose’s persistent coordination with LADWP — the practical follow-through that turned installation into a finished system.
Shaina hired Rose to add solar while her home was getting a full reroof with Spanish tile, and the whole project unfolded with an unexpected smoothness. She immediately found Rose different from other contractors—no high-pressure salesmanship, just clear organization, transparency, and fairness. Out of eight bids, Rose’s estimate came in the lowest, yet it arrived with useful information and no back-and-forth haggling. During system design Rose matched Shaina’s preferred level of technical detail, digging into specifics when asked but also positioned to run the job seamlessly for someone who wanted to stay hands-off. Rose and her crew coordinated closely with the roofing contractor, adjusted schedules around the tile reroof, and completed the install quickly; the few on-site hiccups were handled promptly and resolved fairly. As a practical payoff, Rose’s help with LADWP pushed the meter upgrade through in under two weeks after installation. What lingers most for Shaina is that rapid meter upgrade—an unmistakable, tangible part of why the whole experience felt so efficient.
Christy G. spent 2023 building a backyard shade structure specifically to hold solar panels (Canopy Concepts did the canopy), then set out to find a company to equip it. After wading through flashy sales pitches and nearly getting trapped into a 25‑year lease, she found One Sun on Yelp and everything shifted from skepticism to relief. She connected with Rose Avakian, who leads the female‑owned company and walked her through the technical maze in plain language, including local permitting quirks for the valley and Burbank jurisdictions. With Rose’s guidance she ended up with 12 bifacial Hyundai panels mounted on the shade structure, each paired with an Enphase microinverter. She chose no battery backup because brownouts aren’t a regular problem where she lives; the system feeds power back to the main line and a secondary solar meter records generation to offset her bill. The permitting step took the most time — One Sun drew the plans and the city approval process took roughly a month — but the physical install moved fast. Once approved, the crew installed the panels in almost a single day; because her house is brick they returned the next morning for a few final hours. Without a

What You Can Expect
Adnan installed a 6 kW Enphase system on his roof and saw the whole job move from first quote to the first day of power generation in about six weeks. Much of that time came from waiting on the city permit and for LADWP to install a bi-directional meter, and a few extra days were added for roof repairs he arranged. The crew completed the on-roof installation in a single day. Rose guided him through every step, answered questions promptly, laid out transparent pricing, and didn’t push any upgrades. He liked being able to watch real-time production and household usage in the Enphase app—seeing the numbers right away made the benefit tangible. What stuck with him most was Rose’s responsiveness combined with a one-day install and instant visibility into the system’s output.
Flopez discovered OneSun through a Reddit post and, after reading other customers’ praise, reached out to explore solar for their home. Meeting Rose in person set the tone: she answered a long list of questions without pressure and showed clear expertise. They worked with Rose through the entire process; she stayed responsive before the sale, during the installation, and afterward, and kept expectations honest and upfront. They ended up with OneSun panels installed and a smooth, well-communicated experience — what stuck with them most was Rose’s steady, no-nonsense communication from first meeting to follow-up.
Cm L. was a first-time solar buyer who chose to work directly with the company owner and ended up with a smooth, fast installation on their home. They found the installation crew punctual and appreciated clear, steady communication through each step. The whole process moved quickly — 45 days from the initial call for a consultation to actually generating power — though that timeline can shift depending on the utility and other factors.
