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.
3 Stories That Stood Out
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
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.

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.
Kyle began the journey to add solar to his home and found OneSun communicated clearly at every step. He leaned on Rose as a steady, reachable guide who answered every question and gave straightforward advice about what made sense for the house and their budget. Because the team stayed responsive and honest throughout the process, he ended up confident in the choices they made and plans to turn to OneSun again for any future solar projects or expansions — especially for that same reliable point of contact.
Riley spent about two weeks researching solar companies, gathering seven quotes and comparing not just price but the brands each installer planned to use. After that deep comparison, they settled on OneSun as the obvious choice. The detail that set the experience apart was Rose’s communication — prompt, clear updates kept the project moving and made the whole process feel seamless. Installation showed up on schedule, the crew worked professionally, and they walked away very happy with the finished system. The thing a prospective buyer will remember: the smooth, hands-on communication from quote to final install.
Sunrise moved forward with a home solar installation and found OneSun exceptionally helpful from day one. She leaned on Rose as a single point of contact who answered every question thoroughly and quickly, and who guided her through the entire process from start to finish. The installation also came in at a price she thought was better than competing offers she’d seen, so the project felt both smoother and more affordable than expected. What stuck with her most was having one knowledgeable person manage the details end-to-end, leaving her with a completed system and no lingering headaches.
Steve H. had gone through several solar companies and grown fed up with nonstop calls and pushy sales tactics. Then he connected with Rose and her team, who brought a calm, steady approach: they patiently took as much time as he needed to explain every detail and clearly knew their stuff. The installation flowed exactly as outlined — milestones arrived on schedule and the paperwork and timing matched expectations — and he ended up with a high-quality system that's cutting his utility bill. What stood out most was the contrast in communication; after being worn down by aggressive follow-ups elsewhere, he appreciated Rose’s unhurried, informative way of working that made the whole process painless.
Aneta made owning a solar system — not renting one — a top priority when she moved into a 2,552 sq ft, mostly all-electric home with a plug‑in vehicle. She dug into panel, battery, and microinverter research and scoured local reviews, and OneSun kept popping up positively, so she reached out in early December 2024. Rose became her main point of contact and guided the process with clear, technically solid explanations; after a preliminary call they met in January and moved forward. OneSun designed an Enphase system to meet her strict “no Tesla” requirement, handled permits and all LADWP communications, and took care of app setup and troubleshooting — even fixing a glitch that showed up after she changed her modem/router and mesh network. They installed the array in a day and a half; Eugene and the crew left no mess and finished professionally and promptly. Aneta paid $30,000 for the system (no batteries for now because there’s no suitable wall), compared to a $60,000 quote from another company that pushed rental options; with her usage she estimates a payback in about two years plus the tax credit. As of March 10 the system produced more electricity than the house used: one day it r
Steven had a new solar installation on his home and found the most memorable part was Rose’s hands-on professionalism. She patiently answered his many questions and kept him updated from the start of the project through completion. After the crew left, she came back for an on-site walkthrough, helped him set up access to the monitoring website so he can track system production and household usage, and finished the visit by flying a drone over the roof and sending him aerial photos of the completed array. The combination of steady communication, live monitoring access, and drone-shot images of the panels left the whole process feeling personal and complete.
