    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!

Adam was super responsive and a great communicator. After scheduling a quick visit, they sent me a quick written bid that was clear and straightforward and priced very well and fair. They only recommended replacing what was needed. They said my patio and garage roof was fine and they advised that I only replace the roof for the main 2,000 sq. Ft house which saved me money. I have a great friend nearby who is a general contractor and he came by to inspect the work first hand as well and confirmed they did great. Adam all the paperwork, city inspections and their fees, he was in touch every day with me to update me on progress and the job was done on time and as scheduled. They cleaned up well and it was problem free! They did some extra cleaning of skylights, touch up painting of gutters and even removed some wasp hives for free!

I have a very unusual roof (the whole roof is a flat, walkable roof deck) and Mel, the Nema rep, said they couldn't repair this type of roof because they wouldn't be able to warranty it. Despite that, he stayed and talked with me for about 20 minutes, offering ideas of other decking sealants that could be used, other companies I could contact, or even the possibility of DIY-ing it myself. I'm always SO grateful when companies actually listen to what I want and give me different options. Mel seemed honest and genuine and SO knowledgable about roofs, and I'd love to work with them in the future.

We initially called them out to repair a roof leak after discovering a few broken roof tiles around and below our solar panels. Based on the visible damage, it appeared that area was the source of the leak. After the repairs were completed, we experienced another significant rainstorm and unfortunately discovered the leak was still present. When I contacted Heritage Roofing Solutions, Johnny immediately stood behind his work. Once I had the solar panels removed to allow full access to the roof, Johnny returned and thoroughly inspected the area. He identified the underlying issue and repaired the entire section beneath the solar panels. What impressed me most was that Johnny completed the additional repairs at no charge. That level of integrity and commitment to customer satisfaction is hard to find these days. Throughout the process, the entire crew was professional, friendly, punctual, and respectful of our property. They cleaned up thoroughly after the work was completed and provided detailed before-and-after photos so we could clearly see the repairs that had been made. If you're looking for an honest roofing company that stands behind its work and truly cares about its customers, Heritage Roofing Solutions is an excellent choice. We couldn't be happier with the service we received.
