I wanted to share my recent wonderful experience with my recent service visit with Infinity Solar…read more I purchased my system in 2024 (detailed review also done); during this time, my solar generation has been absolutely wonderful, and sized perfectly by Kay. My electric bill is essentially free over all of 2025 and this year. Some months have a $10 dollar bill, other months negative depending on how sunny each day is. I have had zero issues whatsoever and system works like clockwork. The installation over my tile roof, done through Terrazas roofing, partnered with Solar has also been top notch with zero issues with multiple major storms last year. I would say i was 110% satisfied with my decision to go solar and with Infinity solar. Fast forward to 2026. A series of recent power outages resulted in no power in my home. My initial thinking was that my system should have generated power with a fully charged battery during this outage. After calling Infinity, it was relayed that my system per contract was only set up for load shifting by design, lowering cost which I had decided on. After discussing 2 options to allow for backup power generation, i decided to proceed with the upgrade. Throughout the process, the entire team supported me exceptionally, starting with Sara who stepped in to help speak to me when the service department was not available at the time. As i did'nt understand my contract fully,, i reached out to Kay in sales, whom i did not speak to in 2 years, who really went above and beyond to explain to me in full detail how my system was set up, and options i had to upgrade. Kay treated me like family. I was so appreciative of her kind approach. She helped coordinate a technical call with Joel to fully answer all my technical questions. Once i decided i was comfortable with to proceed with the upgrade, the service team took over, with Vanessa and Brianna helping me schedule my service. Vanessa and Brianna work tremendously well together; super friendly, pleasant, professional and helpful. I requested looking into a couple options which Vanessa followed up on and accommodated without hesitation. A straight forward and exact quote was provided on Thursday. Their service and help was fantastic and greatly appreciated. Upon approving my quote on Thursday, my service was completed on the following Tuesday, much faster than I expected. Upgrade was performed by Ivan, electrician specialist. Ivan also initially setup my system in 2024. His expertise is perhaps, in my view, the finest in the industry. I felt very fortunate and appreciative knowing i hd my system in the best hands. He spent about 3 hours working on my system, explaining all the steps. Work performed was tremendous. Ivan patiently answering all my questions on some of the system parameters forgotten over the past 2 years. System was up and running and verified to work fully with a simulated power outage performed through the fuse box, and through the app. I was thrilled to now have backup power during outages. Billing and final payment was as quoted and super easy. In closing, the real mark of any business is how you are treated after the job is complete. My belief is that Infinity solar lives up to their reputation of being an exceptional 5 star company providing high expertise solar services through all phases of a project; sales, installation, commission, operational life, and post installation services. In a business of fraught with fly by night companies, Infinity Solar is a true gem. Solar done right with integrity, highest expertise, and exceptional, prompt service when called on. Thanks again to the entire Infinity team. 5 Star once again! Dave C

UPDATE: Sadly, changing my original 5-star review to 1 star…read more I'm really disappointed to have to update my original review. When we purchased our solar system from Infinity Solar in 2017, the installation process was great, and we genuinely felt they went above and beyond. We were extremely pleased with our experience and had no hesitation recommending them. Unfortunately, fast-forward several years, and our experience has been completely different. Recently, one of our inverters stopped working. Given that our contract includes a 25-year warranty covering workmanship, labor, and certain equipment, we naturally reached out to Infinity Solar expecting them to stand behind their warranty. Instead, we were told we would have to pay $550 just for someone to come out and assess the problem, followed by additional hourly labor charges for however long the repair would take. When we questioned why we were being charged these fees despite our warranty, the owner, Tim, explained that we lived too far away, that the business wasn't doing well financially, and that it essentially wasn't worth it for him to send someone out. He even mentioned that they were considering closing the business altogether. Needless to say, we were shocked and extremely disappointed by this response. We trusted this company with a significant investment, in part because of the extensive warranties they offered. To now be told that servicing our system isn't worthwhile to them because of their financial situation and our location is incredibly frustrating. Ultimately, we hired another company that came out and repaired our inverter for just $300--less than what Infinity wanted to charge simply to diagnose the problem. It's unfortunate because our initial experience was genuinely positive. However, a company's true commitment to its customers isn't just demonstrated during the sale and installation, but in how it stands behind its products and warranties years later. A 25-year warranty means very little if the company is unwilling to honor it when you actually need service. I sincerely hope Infinity Solar reconsiders how it treats its existing customers. Based on our recent experience, I can no longer recommend them, particularly to anyone placing value on their long-term warranty promises.

Within an hour of posting my initial review regarding a delayed referral bonus, the owner…read morepersonally reached out, apologized for the administrative oversight, and sent the $500 immediately. 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.

Update for my review with OC - Savannah from customer service reached out regarding my experience…read moreand expressed regret over how things went and changes were actively happening at the company. She offered a free panel cleaning, which she set up internally and had their team come out this past Friday without issue. Since the cleaning the panels have been much better performing especially after these past few weeks of misting and rain, about 25% higher output. I didn't think much of it but I get now it's worth doing to get the most out of the panels. Overall a very good response and experience with OC specifically for this issue. I feel that they do want to stand out from the crowd and responding proactively to feedback gives me more confidence they'll take care of issues as they hear about them.

Poor communication and project management…read more My project has been underway for 8 weeks and I'm still likely weeks away from having a functional system (despite having paid over $30K out of pocket). I've had to repeatedly chase the team for basic updates with no follow through. Throughout the entire process, I do not believe the team followed up with me directly, I have had to chase every single update since signing the contract. The original system design I agreed to did not fit my roof (despite them measuring on-site before I approved the quote), during install many roof tiles were damaged and replaced with used (very dirty moss covered tiles). Hopefully I have a functioning system sometime soon, but I have been extremely disappointed so far.

I couldn't be happier with OC Solar! From start to finish, their team was professional,…read moreknowledgeable, and truly committed to finding the best solution for my home. They installed a complete solar system that's already making a noticeable difference in my energy bills. Even better, they set me up with backup batteries so I have peace of mind knowing I'll have power when I need it most. And the locked-in rate they secured for me? That's going to save me money for years to come. The installation crew was efficient and respectful of my property, and the whole process was much smoother than I expected. OC Solar made going solar easy and stress-free. If you're considering solar, I highly recommend OC Solar. They deliver quality work, excellent customer service, and real value. Five stars all the way!

This has been an unnecessarily difficult process. Communication has been non-existent. I have…read morebeen handed off to various people every time I called trying to get information. They do a lot via text, which I liked, but it turned out not at all useful. I would text for updates, and hear nothing back. I would call to find out my contact was out of the office, on vacation, or any number of excuses. This went on for many weeks. I did not know the date for installation until a delivery of equipment showed up at my house unannounced. It was a good thing I happened to be home that day! I thought the installation itself had gone well. They installed the system in two days and everything looked great. Then, I had to wait for the meter collar to be installed. I was told it was going to be performed by their technician. Turns out it has to be done by SCE and that had not been scheduled. After I called again, SCE was finally notified. SCE arrived several days later to discover the cables were too short to install the meter. Now I have wait again for OC solar to come out again and fix this issue and wait again for SCE to finally install the meter so that I can use my new system. I hope the system works.

As a BOD member for the HOA, I had previous experience with Mario Castillo electric when we needed to do an upgrade to the electrcial panel at our home where they did an exceptional job. This time I was working with their commercial division and the excellence of service was no different. The communication, responsiveness and quality of work was excellent. There was one minor issue after hours and they had a service technician onsite within an hour. They worked very well coordinating with the individual tenants in each unit to gain access when needed. Their quote for this project was also competitive, and job was brought in on budget with no extra "surprises". I highly recommend this company for your electrical needs, big or small. Our HOA has picked Mario Castillo as the electrical vendor of choice for any work needed and we are looking into an ongoing maintenance contract with them as well.

Pricing is quite high compared to other quotes I received but very transparent and worth it. Took one star because of poor communication and lateness. They advertise working Saturdays and do some of the crews but according to their office, that is all a mistake and they only work M-F 9-4. That plus the crews showing up 2.5h late each time meant that I had to take more time off than anticipated for them to complete the work. But now I know and I will absolutely use them again.

Just another 5 star review adding on to the many that NexGen Construction has and deserves. But…read moresince my particular project was for batteries adding onto existing solar panels that they did not originally install, I figured I can give my perspective with the service they provided. Without making this review long and boring, let me just say Eric the owner, Rich the office manager and Zach the lead installer (and the rest of the crew) was great to work with from beginning to end. I was anticipating that there might be some issues adding batteries on to an existing system, with not only the installation itself, but with the approval process from Edison and the city. But Eric, Rich and Zach worked as a great coordinated team to get through any obstacles that came up. Anyone who's been through any type of home construction/remodel knows that nothing is perfect. But it's how the people you hired responds to those hiccups to make things perfect, is what counts the most. And I can honestly say NexGen exceeded expectations. In regards to value, Eric is upfront and says they are not the cheapest, but they are certainly not the most expensive either. So when it comes to my peace of mind, I'd gladly pay a little more. Go ahead and give them a call, I certainly will when I want to add even more batteries

When one of the (many) things our home inspection revealed was that we were in dire need of a new roof, that sealed the deal. And since we like to support local businesses whenever we can, after a little research we landed on BYLTup. Honestly, we can't say enough good things about the whole BYLTup team, or about Dominik in particular. I'm not even sure where to start. For one thing, from start to finish we had to communicate long distance by Zoom, FaceTime, and text because we hadn't moved yet. Nonetheless, we had absolutely no qualms about our project being in good hands because having met Dominik first on Zoom and then IRL when we were out there for a couple of weeks, we knew we could trust him 100%. I mean, the guy knows his stuff, is clearly all about the details, and he's one of those people you sort of feel like you've known forever after just a few minutes. Seriously. He couldn't be more personable or considerate. Just good people. But about our project: It was no small task. Our house is a 1912 Craftsman that--believe it or not--still had the original roof, with various layers that had been added piecemeal over the years as needed. We got a beautiful new roof and a fully permitted 11.51 Kw solar system that'll generate 14,780kWh in year one, all within about 2 weeks once construction started, and the team was so clean you'd never even know they were there. Actually, I take that back: one day when there was considerable dust, soot and debris --which, unfortunately landed in out neighbor's yard after they'd just washed their windows and their car, Dominik went over personally to apologize and offered to take care of any necessary re-cleaning. He totally smoothed out the understandably ruffled feathers. And when our project was done, our place was totally clean. One more thing: We couldn't end this review without giving a shout out to the chief admin angel Erica, who was always personal, professional, and prompt in all our communications. ---Margot and Don C Huge fans of BYLTup!
