    SunPower X-22 Series installed by SolarVast
    F W.

    SolarVast installed SunPower X-22 solar panels on my house back in 2018. I have referred many friends and family members to Ken Lau of SolarVast for their solar installation. SolarVast's installation was quick and they handled all the permits and paperwork with the City. I have not had any problems with the installation or the solar panels. I highly recommend SolarVast and SunPower's solar panels if you are in the Southern California region.

    Very smooth process from beginning to end. I highly recommend Solar Vast! They're very professional and I'm extremely happy with my Solar.

    It can be overwhelming to know which solar company to go with with so many options out there. Willie from SunPower assisted us 2 years ago with our solar purchase. He was helpful from the beginning and has continued to follow up each year for a system report to make sure our panels are running smoothly. With 2 EV's, our electricity bill is either net zero or we have gotten a small credit on our bill. We plan on using Willie again to help us with our next solar install in our new home. Go with Sunpower, you won't regret it!

Because of that experience, we were very cautious when we decided to add more panels and reached out to several different companies. From the very beginning, HPM Solar stood out. They were easy to work with, communicated clearly, and consistently kept me informed about every step of the process. There were no surprises and no guessing about what was happening next. We were also extremely fortunate that an earlier installation slot opened up, allowing HPM to fit us in just in time to take advantage of the expiring tax credit -- something we truly appreciated. The installation crew was excellent: professional, efficient, and respectful of our property. They did great work and made sure everything was cleaned up before they left, which really showed their attention to detail and pride in their work. Overall, the entire solar process with HPM Solar was very smooth and stress-free, a complete contrast to our previous experience. I would absolutely recommend them to anyone considering solar.

They were professional, clean, cordial, and the end result was exceptional. I am very pleased with the work performed and everyone that was involved.

I observed the installation process asking questions and am satisfied that I won't have any issues.

Question how much to repair the leak? We will not give a quote until you pay the $975. Thanks, and bye. Number 2, another Tesla and this fellow walks around the lawn and says we will replace the cap around the chimney box. $3500, Thanks, and bye. Number 3, Walks the roof, inspects the attic for leak and reports we must remove 4 solar panels, replace 500 square feet of plywood and replace the shingles, the damage was caused by the solar installation and with a senior discount, $8,750. Keep in mind the roof has not leaked after the solar was installed, 11 years ago. Mr. Joe installed our solar and no one will move our system but he and his crew. We call Mr. Joe, his crew arrive in a work truck with ladders, inspects the attic and finds no excessive water damage to the plywood, removes the chimney box lid, climbs inside to inspect and reports, replace the cap and you are good to go or use some sealant and flex seal first and review the results. THAT IS HONESTY, INTEGRITY AND SKILL!!! We have known Joe for 11 years and we are grateful we located he and his company and you will be too!

Every person who came out was professional and respectful. What really set them apart was handling both our full roof replacement and solar installation together.

For the quick summary, there was a mistake in my installation, it was not handled well and the system works well but only after a long struggle. They price match but hard to say if I felt good about the price in the end either. Overall, it is very mediocre. After talking to 4 companies, I decided to go with OC after they honored a price match from a competitor. It was a fairly large system, 15 panels and a Tesla power wall 3 and needed to be added to existing system as my current one was underpowered and required due to new builds in California. Total was about 33k, out the door. It may not have been the cheapest offering but shopping for solar is not my favorite experience and I went with what I felt was at least fair for what I got. I primarily worked with Don from sales and Brooklynn and initially seemed fine and for all intents and purposes, it should have been. I chose to get HOA approval and pay for it myself so it did stall the project through no fault of OC. My HOA requires applications for major projects to be submitted along with a sizable fee, and I chose to do it by the book. I dropped the first major deposit of 10k and the installation was scheduled around July 2025. The next part is where the struggle began. The day of installation, the installers tell me the panels cannot fit in the design that they were given. They asked if I wanted to pivot to another part of roof and just install it then and there. I call OC and they admit the design cannot possibly fit my panels on this small area of my roof and I cancel the project and have them redo the plans and for me to go through HOA again. This leads to a very frustrating back and forth with Don and later Brookylnn's superiors as I no longer heard from her. I had about 10 calls or more trying to clarify what to do next and was met with a lot of resistance about what happened. It turns out the plan was actually the original estimate from Don (sales) and for some reason just pushed through their architectural team without consideration of the size. Don's superior Chandler even spoke with me about this and though I can't recall their explanation for this mistake, they spoke as if this was my issue with wanted to go through HOA and that they had no power to stop the project. If I had written this review after this call, I'd recommend no one work with these people. It felt frustrating and at times demeaning, given that they do this all day and I don't know what I'm talking about. After I got my second approval, OC refunded my fee to the HOA approval, but only after I explicitly asked for it. We eventually moved forward with the project and inspection when fine. My guess is had we not had this irresponsible prelimary design provided by Don go through their "architectural" team it would've been fine and none the wiser. As of this writing, the panels are working as intended and I had such a sour experience, I just moved on. But now Don and company requested a review for their internal systems, so here is it and a Yelp one that they did not ask for. In the end, like most of these experiences, it's not the mistake that upsets me, it's the handling of it. Communication started fading when things got more difficult and the lack of empathy or consideration for some dropping this much money on something they will do maybe 2-3 times in their life is disappointing. Much of the time I asked them and myself, how should I know this plan wouldn't work? Sure the HOA can't legally stop me, but I have to live with them, not OC. Whoever may have gotten this far, thank you for hearing my rant. Odds are you will have a fair experience but the truth is, most of these companies are interchangeable. They are all middle men and their strength and differences lie in the customer service and coordination. I didn't expect but solar buying is probably more similar to going to a car dealership. Do your research, advocate for yourself and don't get your hopes too high and it will probably be fine. As for OC, I think in the end they are just mediocre. They're like anyone else you may talk to. The processes are probably similar and I'm glad the system has worked well, which helps my scoring of this review. Maybe they just got lucky with me at the time, as I was getting fed up talking from one salesperson to the next and they price matched. I'm sure others will and can do the same so whoever you go with, as long as you are on top of it, it will go fine.

Dan later answered additional questions I had then adjusted quote. The installer, Carlos, looked at the actual site conditions then discussed various options (like spacing of posts, how far to set posts from edge of patio cover, where to put downspouts, etc.) with me beforehand. Every day, Carlos would keep me updated as to the work being done. Their electrical, Mike, installed the lights, outlets and controller exactly where(& how) I wanted them. It was not some "cookie cutter" install off a pre-set plan. Things were installed the way my family & I wanted. Brittany in office kept me updated on permitting process, scheduling, inspection, etc. Initially had company install a pair of attached to house, solid (& insulated) patio covers (at kitchen & by living room). Family was so pleased with finished patio covers that we had Rooms come back and install a 24' x 13' standalone, solid, insulated patio covers outside bedrooms. Carlos made all 3 patio covers blend together. Mike wired all the lights (8 in the initial patio covers & 8 more in the standalone patio cover) so that all are controlled be a single dimmer switch. Needed to have some concrete work done under the patio covers and nearby. Rooms' recommended concrete people, James Austin Concrete, did excellent work and coordinated with Rooms for minimum disruption to patio installations. Initially called 6 companies (all local 4 star+ on yelp) for quotes. Rooms was 1 of 2 that was willing to go through the permitting process with the City. A 3rd wouldn't give me a quote because I wanted the patio covers to be permitted. The other 3 companies said that because the existing wood, open lattice patio covers had been permitted (in 1989), a new permit was not needed. Don't believe them. Big difference between open lattice wood patio covers and solid, Alumun patio cover. Plus requirements change over time. Turned out that the required dimensions for the posts' concrete footings almost doubled in size (in all 3 directions). Getting a permit means everything is built to meet City requirements. Only downside is long wait (13+ weeks) for City to approve each of the 2 permits. Several neighbors have already asked about Rooms. Even the city's building inspector asked for Rooms contact info. He wants a patio cover(s) for his place and was impressed by the work Rooms did for mine.

    With so many options out there for solar install companies it was all a bit confusing. After doing…read moreresearch and reading reviews some great and some absolutely terrible I decided to to give Simply Solar a call as the reviews were nothing short of great. They were very prompt with their communications which was a great start. I scheduled an appointment with William on Aug 19, 2019. Here's the thing I loved most about the salesman William. He wasn't pushy at all with getting me to sign a contract or bugging me constantly if I had made a decision. He did check in a few times if I had made a decision but again not pushy. Not sure about anyone else but I hate pushy sales people and instantly get turned off. But back to William, he is a down to earth and up front salesman. Very knowledgeable about the product he is selling and helped direct me in the right direction. If your looking for honest accurate info William is your guy. So after meeting with 2 other companies just to see what my options were. I pulled the trigger and signed on with Simply Solar. The cost was a bit higher than the others but well worth it. Next person of communications was Ashley who is in house to keep the project moving forward. From start to finish her communication and timeliness in response was excellent. Ashley was constantly on top of communications with my roofing company as I was getting both done. As soon as the new roof was on the install Techs came in. I cant remember the names of the install tech but there were 2 of them and again like everyone else at Simply Solar they were top notch. Friendly, Super careful with the new roof, and went over exactly what they were going to do. I didn't realize how quick they would get it installed in just 2 days including a panel upgrade. After that was all done Dan again who was awesome came by to finish the stucco work where they had done the new panel upgrade and made it look finished. So now everything has been installed and we are just awaiting confirmation from SCE to go live. I have heard horror stories of people waiting months to be approved for going live with their solar. Simply Solar again was on top of communication with SCE and our system was up and running in less than a week after the install. Over all I think the whole process once things got started was probably less than 2 weeks. AMAZING!!!! Its been about 6 months now since I have had the panels and im so glad we got them. The first few months we were in the hole with SCE as the days were short but now that the days are longer and more sunny were putting more into the grid and chipping away at our yearly bill. At the rate this thing is running we should be close to 0 due. If your looking to go solar and want the best service, product and experience this is your go to company.

I snapped some pictures of the leak, sent out quote requests on Yelp, and James from Van Lund replied almost instantly -- said he could be here 7 a.m. Saturday. Most other places couldn't come until Monday and more rain was coming all weekend, so that wasn't happening. James showed up right on time, found four cracked tiles letting water in, tarped everything perfectly on the spot. It poured cats and dogs Sat-Mon and we didn't get another drop inside.

Will update when I hear back. Would not recommend SolarMax at this point until they improve their customer service. Look into other companies and their service reviews since you will most likely have to contact them multiple times with questions about the system/billing. They were very prompt and quick with reaching out and getting back to us when they were trying to sell us solar. However, now that we have been customers for years and our sales rep left, it takes multiple calls to even get through to customer service and then multiple follow up calls after since they have to email other departments to get an answer and do not call back. It seems like they are short staffed and for a big company like this should invest in more staff for customer service. That way they can provide the same experience we received in the beginning. It's been almost a month after I initially contacted them and my question still has not been answered. Seems like there is only one customer service rep and she definitely needs help.

After inspecting the roof, I discovered a very concerning issue. When SolarMax installed the solar panels, they hired a roofing company to modify the roof beforehand. That roofing work was never properly completed, leaving a large section of the roof without shingles and exposing bare wood. As a result, there are now multiple areas of our home showing signs of water intrusion and possible mold. I immediately contacted SolarMax and informed them that this was an urgent matter requiring prompt attention. More than 24 hours have passed, and I have not received a response. I was told they would reach out to the roofing company they used, but there has been no follow-up. What I do not understand is how SolarMax could proceed with installing the solar panels, mark the job as completed, and leave our home with such a significant roofing defect. I am extremely concerned about the potential extent of the damage to our home, as well as the possible health implications for my family. I have never had allergies in the past, yet I began experiencing them shortly after the panels were installed, which raises serious concerns about mold exposure. I am hopeful that SolarMax will take responsibility for this issue and fully address both the roofing defect and any resulting damage to our home. However, I am very disappointed by the lack of communication and urgency shown so far.
