    Solar panel installed on the roof
    Tahir A.

    I have my system installed which consists of solar panel and battery. The sales process went smoothly. Mike addressed all my questions and their pricing is the lowest I could find. Then, we had to go through permit apply which was a bit slower than I expected. I understood that it is out of the company control but I wish the communication during this time could be better. I had to escalate to Mike few times but he immediately took care of it. The installation went well. And the final inspection also went well. Overall, the experience is superb. I really like my system especially the battery. Having a back up is really nice.

    SunLux successfully completed our solar + battery installation in Fontana, CA, and the entire process was handled professionally from start to PTO. We found Sunlux through outstanding Yelp reviews, which helped us choose them. The project began with an initial meeting with Mike Valencia, followed by smooth design and coordination. Our project management started with Gabriel Benko during the design and operation phase then transitioned to Elizabeth Haygood, then Jessica Delgado, who managed inspections and the final PTO approval with SCE. Despite the handoffs, communication remained clear and consistent. Our system includes an 8.28 kW solar array (18 panels) paired with 1 Tesla Powerwall 3. Pre-installation inspection, installation, city inspection, and utility approval were all completed efficiently. One of the biggest strengths of SunLux is communication. We were kept informed at every stage of the project, and any questions we had were answered promptly and clearly. The technicians were professional, courteous and did quality work. Overall, SunLux delivered a well-coordinated project with strong communication and solid technical execution. Highly recommended. Deserving of 10 Stars.

    Worst experience ever been going at it for 2 1/2 months back-and-forth through emails and calls, which are all saved for proof leakage on the roof when the solar and roof was done at the same time through sunlight they don't answer their phone a bunch of excuses, the guy that handles the construction that they have to speak with the management ongoing upon ongoing

    I am happy with the solar system I got through Sunlux. In October of 2025, I realized that the IRS solar credits were set to expire early at the end of the year due to the spending bill congress passed in July. I contacted 4 solar companies, and 3 said they could get the job done in time. Sunlux had the lowest price by $9,000 - $30,000. I liked that Mike Valencia is an owner, so I knew I was not working with a salesperson who might not be with me throughout the process. I purchased a 16 panel, 7.36KW, 2 Powerwall 3 system. From contract signing to Permission To Operate (PTO) took some time, but we got the system up and in service before December 31st. It did take almost 5 months from contract to PTO. Southern California Edison took 2 1/2 months to give us PTO. We did have some issues with communication at first. It turns out there was a key employee who was going through something. Sunlux hired an additional person to help. We then worked things out and communication has been great since. I noticed other reviews that remarked on communication. As far as I can see, that is resolved. I developed a good, friendly working relationship with Michael Valencia, Guillermo Santomauro, and Jessica Delgado. I also got along really well with the installers and technicians who came to my house. The installation and permit process did not go perfectly, but Sunlux took care of everything to my satisfaction, and to the satisfaction of my city (and we had a very particular inspector). If I saw something I did not like, Guillermo worked with me to make sure I was completely satisfied. Sunlux working with me to insure total satisfaction is why I gave them 5 stars. My safisfaction includes the very fair price, a good, safe system, and a company/people I feel confident with going forward. On my first bill reflecting a full billing cycle with solar, my Edison bill was only $10. I won't really know how well my system meets my needs until I have the air conditioning going full force during the summer. If needed, I will have a couple more panels and even another Powerwall added. For now my system produces far more power than I use. The only thing I don't like is having Tesla Powerwalls because Elon Musk's behavior and actions are contrary to my values. Sometimes compromises have to be made. They are good batteries. I feel confident recommending Sunlux, and urge others to consider them in their pursuit of Solar energy.

    My third project with Sunlux was the Tesl Powerwall. We had a solar installation at our old house, then we moved and our new home had a tiny solar array, so we added another 24 (I believe it was) panel system a couple years ago, We'll, we FINALLY got the battery backup and they did a great job. Price was clear, including upgrade options/pricing, and they worked with me regarding the installation location, etc. Unfortunately, the county required safety poles in front of the Powerwall because our RV travel trailer parks next to it ( even though there is no geometric possibility of hitting it with my trailer!), so they had to install them and call for another final inspection. I'm going to remove them since they are worthless! After everything was wrapped up we got the PTO and everything is working perfectly, but we have not yet experienced a power outage. But I'm sure we'll be just fine when that happens! I always recommend Sunlux to people I know who are considering solar or battery backup. Price was the best I found, and I've been happy with their services for two homes, three projects!

    14KW Tesla Powerwall

    After some thorough research I decided to hire SunLux to do a new solar system install on my home. I had an original Solar System installed in 2004 made in Germany but it was time to upgrade. Mike Valencia took my specs - recommended a system - and impressed upon me that SunLux was not a 'middle man' but indeed a Solar Install company with over 100 employees directly involved in each installation. So - if a problem occurred I had only to go to SunLux to get help as opposed to chasing online web companies that subcontracted installers. SunLux delivered an ON TIME excellent install and the followup was quick - the interface between myself - SunLux - and So Cal Edison was efficient and prompt. When the sun is shining my Tesla Powerwall batteries are usually re-charged by 10AM and until sunset we put back up on the Grid on average 26-30 KW daily... my Edison bill dropped from $550 monthly to $28. Efficient, honest, responsive and solid follow through made this new solar install by SunLux work extremely well. Highly Recommended!

    Solar Panel

    SunLux was one of three recommended by the Consumers Report. They offered us the top of line in Solar Panels with 460 kWh and the newest Tesla battery back up, with the best prices. Mike Valencia was our sales rep. He explained everything in detail and always answered all my calls. All the paperwork was done by phone including signatures. Then we were switched over to Gabriel Banko, who took over the installation, which was timely and done by SunLux. Gabriel was always there to answer questions. The men who did the installation were kind and professional. Lastly our account was given to Jessica Baitzman who did all the work to get us hooked up to Edison. We defiantly recommend SunLux. Best prices, service and customer service.

    I would highly recommend SunLux to anyone looking to install Solar Panels on their home. We researched multiple vendors before deciding to go with SunLux. In comparison to other companies, we felt SunLux had the best price, presentation, and overall comprehension in terms of what we needed. Mike Valencia, VP of Sales and Marketing, did a great job explaining how solar would work best for us. Elizabeth Haygood, our assigned project manager was always available when we had questions about the process and was consistently providing us updates on the status of our installation. It took about a 6 weeks for the project to start (this was due to the holiday season). Once it got started, things moved very quickly. The actual installation of 32 panels took 1 day. The following week, the city inspector came to check the work and approved it within 15 minutes. Prior to the inspector arriving that afternoon, a SunLux supervisor arrived the morning to look over the installation and make sure everything was up to code. The following day, the city stopped by and installed the new meter. Three days later we were connected to the grid. SunLux did a great job through the whole setup and installation process. We have had the solar running for a week now and everything looks good. Our hope is that SunLux does just as good a job fixing issues when/if things breakdown after the project is done.

    Our new Tesla battery!

    I've been studying adding solar panels and battery back-up for a few years. Thanks to OBBB we pulled the trigger this year and couldn't be happier. The purchasing process was great. Mike Valencia was patient and answered all of our questions. Once we signed on, our Project Manager was excellent. We were made aware of the overall process and timeline. Communication was timely and accurate. They explained exactly what was going to happen and when and they were extremely accurate. The installation was done in one day. They showed up with a large crew and the team's process was like clockwork. The guys were polite and friendly and left my home/yard in great order when they were done. The process to get the system inspected and on-line with SCE was seamless and much faster than I thought. I would highly recommend SunLux for solar installation!

    You get what you pay for with this company. CHEAP FOR A REASON. If you're considering solar panels don't choose a company that cuts corners.

    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 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

    Our experience with Infinity Solar's post-installation support has been extremely frustrating…read more We selected Infinity Solar partly because its sales representative repeatedly assured us that post-installation support would be handled smoothly. We were told: "We will be your number 1 phone call - always for all service related inquiries and anything to do with your solar system. We will address the issue and bill Solar insure so they can pay us for our services," "Year 9 or 11 or 30. It's all covered for us and you," ""The only time you contact solar insure directly is if Infinity goes out of business," "you can expect the same level of customer service throughout the project and afterwards as well," etc. Those assurances were a significant factor in our decision to choose Infinity Solar over competing installers. Unfortunately, our post-installation experience has been very different. Our system was installed in 2024. In July 2025, Enphase confirmed that the System Controller 3 included in our contract had never been installed. Because the controller's primary purpose relates to backup functionality during outages, there was no obvious indication during normal operation that a contracted component was missing. Infinity acknowledged that it had been "missed". Rather than immediately correcting the omission, Infinity proposed various solutions involving additional load center and other components costing from $4k to $11k just to remediate the issue. We were surprised that correcting a component omitted from the original installation was presented as a new project requiring thousands of dollars of additional equipment. After doing my own research, sending repeated follow-up emails, and spending months corresponding with Infinity, Infinity eventually acknowledged that it had missed the original controller and we reached a simpler $888 meter-collar solution, with Infinity handling the permitting process. The controller was installed and programmed in Nov 2025, but the permitting process continued into 2026. In July 2026, Infinity said it was still going "in circles between the fire dept and the city," and in September said it still had not heard anything definitive. These updates came only after we initiated follow-up emails requesting status information. In September 2026, our Enphase app reported a gateway-measurement problem, while reported production dropped about 40%. Enphase customer support found a discrepancy between the production meter and microinverter data and recommended an on-site inspection of the production-meter wiring and current transformer installation. We contacted Infinity. No response. After two more follow-ups and a 9-day wait, Infinity finally responded and informed us that an on-site visit would cost $400 for the first hour and $150 for every additional hour merely to diagnose whether the problem qualifies for warranty coverage. I am not opposed to reasonable fees for truly non-warranty work. I object to this substantial diagnostic fee never being clearly disclosed during the sale. We were given the impression that Infinity would address service issues promptly and bill Solar Insure. Infinity now says the fee is diagnostic and customers must first pay $400 plus $150 per additional hour before learning whether the issue is related to workmanship or warranty coverage. Customers are also given no indication of how many hours the diagnostics may ultimately require. Infinity further suggested we contact Enphase Care and other companies to solve this issue instead. Completely different from what they promised during the sales process. The fee is high enough that many customers may decide not to pursue diagnostics at all, making no determination whether it is a workmanship error. Secondly, the issue is not the existence of a diagnostic fee. The issue is transparency. Had this policy been clearly explained during the sales process, customers could have made a fully informed decision. In our experience, the sales promises, system design, warranty expectations, and actual service process were not communicated transparently. Prospective customers should insist on written disclosure of all diagnostic charges, warranty exclusions, system limitations, included components, and permit responsibilities before signing. If your system never develops a problem, you may have a different experience. If it does, be prepared for delays, repeated follow-ups, and a post-installation experience that does not match the expectations created during the sales process.
