    HPM Solar is an exceptional solar company.  Dan and the team at HPM Solar truly care about the customer's needs and are not trying to just make a sale.  They listened to our concerns on how we did not want this solar project to become an eye sore once installed. Dan and the team came up with a solution that limited the number of components that needed to be installed on the exterior walls of the house and moved various components to the garage. This created a clean and finished look with the install, limiting conduit lines and equipment for guests to see when entertaining.  We couldn't be more pleased with the process and installation! The system is working as designed and we are looking forward to seeing a huge reduction in our SCE bills now and into the future. We would highly recommend Dan and the team at HPM Solar for your solar needs!

    The Guys at HPM were great from start to finish. Mark came to my house with all the cost analysis and layouts for the system and explained everything very clearly. He had all the price breakdowns for labor and equipment ready, with all the equipment and warranty coverages as well. His quote was as right in line (slightly lower) with others companies in the area. Once we got approval, His installation team, headed by Erik, showed up and did a phenomenal job. His follow up after the install was also very impressive. We had a couple small issues after the install that they immediately addressed and fixed. Overall, I'd highly recommend them. We've had a lot of home projects done and HPM was by far the best experience we've had with a home improvement project.

    These guys are the real deal. Don't waste your time getting other bids. Trustworthy, professional, hard working and they care about your project as if it's their own. From the owner Dan to the project managers like Eric and Jose in the field they're all around nice guys. They were at my house for every inspection and explained the process in depth to my family whenever asked. Would definitely use them again!

First company arrives in a Tesla and then uses my ladder to climb into the attic and reports we have to have a moisture test with various monitors for possible mold and then we will have our lab provide a 16-page report.... $970. 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. I didn't want a roofing company and solar company pointing fingers at each other down the road -- OC Solar eliminates that headache entirely. Their pricing was competitive, and their substantial warranty sealed the deal. Highly recommend them if you're considering solar!

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.

    I cannot say enough good things about Source Solar. We just finished our first year of using the…read morepanels they installed in the summer of 2019 and everything has worked as advertised and then some. Ryan and Josh were so professional, efficient (from delivery of the panels to our garage to final installation was 3 days). We have a tiled roof type that makes installation difficult without damaging the tiles, and as a result many companies wouldn't even bid on the project. Their pricing was fair and their system for protecting the tiles worked great. Only a few tiles were broken in the process, and they not only fixed those but also fixed a few others that were broken but not by them. We were connected with Source Solar through an independent sales person. The design and software allowed us to very precisely see the cost of a design and the energy production. It has been very accurate and we ended up almost exactly using what we produced (we produced a little bit extra but also charged our car less during Covid). The monitoring app they installed has functioned perfectly and we are actually hooked on watching our daily intake and lamenting any passing clouds that affect our production. One time we noticed that a single panel seemed to be producing less than the ones around it. Although we weren't sure if it was just caused the the neighbor's chimney shadowing that panel more than the surrounding ones, they were out within a few days and swapped it out for a new one. Sure enough, the new one had better production. We are newbies to the world of solar energy, and they very patiently answered all our questions about the time-of-use energy plan, yearly billing, production and use estimates, the monitoring app, etc. We highly, highly recommend these brothers and would give them 6 stars if we could. The only thing we regret is not doing this years earlier.
