    The plans for the solar.
    Christy G.

    Prepare yourself for a gush of love for this company. I built a shade structure to specifically hold solar panels in my backyard in 2023 (shout out to Canopy Concepts), and then needed to find a solar company to install the panels. I got quotes from so many solar companies, and every single one felt like a scam. All flash, no substance, and I didn't like that no one could give me very straight answers on cost. Everything was geared towards leasing. I almost got looped into going with SunRun, and tricked into signing a 25 year lease, which I backed out of immediately. (Costco, don't let them in your store). Finally, I found One Sun here on Yelp. It was the beacon of solar powered brilliance I was hoping for. (I know I'm gushing, but I seriously went through contractor search turmoil to find them.) OneSun is a Female owned company, with Rose Avakian at the helm. She knows everything there is to know about solar install, and breaks it down so it's easy for novices to understand. There is a lot of technical speak for Solar, so it's easy to lose your way. Rose was so easy to deal with, and made the process go extremely smooth. AND show knows how to work in the valley, and the different jurisdictions needs. Now I had already done my due diligence in building my shade structure, and knew sort of what I wanted on it. With Rose's help, I ended up with Bifacial Hyundai panels, 12 total, with enphase micro inverters on each panel. No battery backup since I live in Burbank, and brown outs are not a regular thing. What power I generate feeds back into the main line, and there is a secondary solar meter on the system that sees how much power I generate, and deducts that from my bill. The solar install was super quick, even though my situation is a unique one, and I wasn't putting them on the roof. I read too many horror stories of solar panels causing a house to need to be re-roofed. I had to wait a few weeks for the plans of exactly what panels I was installing to be drawn up by One Sun, then approved by the city. Maybe took about a month. Once approved, I purchased the panels, and they were installed in almost 1 day. My house is brick, which makes it harder to work on, so they had to come back the next day for a few hours to finish the install. Without me asking, they even went out to color match the exterior paint on my house so they could hide the new chords they had to add. ABOVE AND BEYOND!! What took the longest was getting the meter the city had to install, installed. That was about a 3-4 weeks waiting period, where I didn't know when the city would just show up. This waiting period is totally out of One Sun's control since it's based on when the city can get to it. They came July 3rd, when I luckily was home, and approved the final install, and put in the meter. Even the Burbank BWP workers commented on how great everything looked. If you're seriously looking for a good, reputable solar company, I can't recommend One Sun enough. I waited a month after the solar panels were installed and turned on to make sure everything was working before I posted this review. I purchased everything out right, but they do have other payment options, and can work with any roof type, and will work with you on ways to afford solar for your home. Thanks Rose!

    Rose is everything you want in a contractor: highly competent, highly transparent, well-organized, and extremely fair. Immediately upon engaging there was a clear difference - none of the slimy vibes or off-putting salesmanship of the competitors, all of the professionalism and knowledgable competence you could hope for. Her quote was the lowest I received out of eight, but was delivered with the highest level of professionalism, useful information, and lack of fuss or back and forth. During the system design phase she was happy to meet me at the level of detail that I preferred and get into the nitty-gritty without brushing me off - but I also suspect she would be great at simply taking care of it all seamlessly if you preferred to stay hands-off. Our solar was installed concurrently to full reroofing with spanish tile. Rose and her team were really great about being flexible with scheduling around the roofing contractor. When it came to install, the work was quick and well done; some inevitable on-site hiccups happened but were sorted out speedily and fairly. As a bonus, her help wrangling LADWP meant that our meter upgrade was less than two weeks after install. It was all truly a pleasant experience - 10/10 would recommend.

    I want to start by saying our installation was bumpy, which is why I think they deserve the 5…read morestars.  Why i went with AMECO:  I wanted someone with moderate prices that I could trust, someone that won't leave me hanging if something went wrong. I read enough horror stories online about 8 month projects or installers going bankrupt that I needed to make sure my installer will be in business when something goes wrong. Ameco seems to have a good reputation and has been around for 44 years. Plus, our sales agent Rudy was the most responsive and frank of the 6-7 i talked to. Some sales teams tried to strongarm us into a more expensive package with fear mongering or claims of knowing more about the industry. Other companies' (including one i was seriously considering) sales seemed to be sweeping details about the contract under the rug, which gave me a bad vibe. AMECO was not the cheapest, but below average. There were two things that shocked me though, but didn't end up impacting my installation: 1) AMECO is owned by NRG (one of the other companies we were considering, which DID have the lowest price but also some negative reviews) 2) AMECO doesn't actually use its own in house crew as suggested by sales in north bay, but uses contractors. I was a bit pissed about this when I found out since I was specifically looking for installers with in house teams, but the guys they brought in were consistent each time and did a decent job and communicated pretty well with headquarters so I gave them a pass. The installation process: We were assigned a project manager called Ivan. I have to say Ivan was stellar. Prompt in his communications, knew all the details, was on top of my questions before I even asked them, proactively provided updates, chased down issues for me on a moment's notice. He always picked up when I called, always texted back promptly. Every step of the process I felt informed, in control, and understood all the current issues we needed to chase down. Even though the installers weren't in house, he kept a tight leash. The installation itself was blazing fast. I had budgeted 3 months for the signing to installation at least, but they finished it in roughly two including permitting, engineering - maybe because it's not peak season? It was so fast I wasn't even mentally prepared when we cut over to solar power. The installers that came were knowledgeable, good workmanship, showed up a few hours before the inspection and physically walked through every component to ensure it was done right. Passed inspections the first time. I had no complaints. The followup issue: Our system shut down a week after it installed. Our power provider gave us permission to export energy, i turned on the feature in the device and it died. I was freaking out since I wasn't sure who to call or whether Ameco would still care since they'd technically finished the installation. Called Ivan who scheduled to have a tech come out in a couple hours (though it was later rescheduled to the next day). Turned out my system was faulty and had to be replaced by Tesla. Again Ivan communicated expectations clearly to me about how long it'll take for the part to arrive, when the team would come out to install it. Turned out his plan was pretty accurate (off by 1 day since the part didn't arrive on time) and I had a functional system 4 hours after Tesla delivered the replacement part. There was also a billing question I had (because I didn't read the invoice), which they responded pretty promptly and cleared my confusion in 4 hours. Overall, the service I received was great. Every step I knew exactly when the next milestone was, how it was going to be done and what I needed to do. I was never left hanging and I felt Ameco had done its best to ensure my system was installed the right way. Time will tell how the workmanship holds up, but so far so good. Aside from the original dissatisfaction about not having in house teams, there was nothing to complain about. I think if you get a project manager like Ivan on your installation, you'll be in good hands.

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.

I've owned my home for 15 years and have had many companies come to repair or upgrade something. It's hard to find a company or contractor who does a great job, communicates well, charges reasonably, and finishes on time and on budget. All In 1 Energy Pros did ALL that. I contacted multiple roofing companies to get quotes. They not only came in with the lowest quote, they also thoroughly explained what they would do for that price in a way I could understand. I worked with Sophia in the office who was VERY communicative as well as just a sweetheart. She informed me of everything I needed to know to prepare for the work. The guys she sent to the site were friendly and worked fast. They removed the old roof and a few damaged plywood panels in one day, and they installation of the new roof took 1 and a half. It was clear to me they went above and beyond to make sure they did a quality job. It's also worth mentioning she never tried to upsell me on anything, they replaced damaged flashing over a few of the vent pipes, and even cleaned my gutters free of charge. Even with this extra work, though they were small things, I didn't pay a penny over what they quoted me. The cleanup was very thorough. It was like they were never there (except for the gorgeous new roof). Copy and paste the above for the attic insulation. One last thing about the legitimacy of this review. (First of all, if you've made it this far into the review, I'm impressed) I hardly ever write online reviews unless I'm super pissed about getting burned by a product or service. Sometimes shouting your rage into the void can be cathartic. With Sophia and All in 1 Energy Pros, this is one of the rare examples where I'm truly blown away by how good these guys are.
