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!

We put in an emergency request within Yelp for an electrician for a circuit breaker problem. From…read moreYelp, the request goes out and electricians respond. Nick was the first to respond within minutes...at 8 o'clock at night! We FaceTimed him (after seeing all of his five star Yelp reviews) to show him our problem, and he gave immediate advice, which we followed. He said he would be out first thing in the morning. He was! We had to replace a few circuits that were fried and decided to do a full breaker box maintenance (to prevent this from happening again) because it probably hadn't been serviced...ever...in 25 years. Nick went far over and above expectations. He threw in upgrading a garage outlet while he was here and put in a whole house surge protector at a very discounted rate since we went with the full breaker box maintenance package. Our breaker box now looks and works like it is brand new. His work comes with a two year warranty! Nick was extremely personable and honest. I added him to my contacts because we will be contacting him with any future electrical issues. In short, there is a reason for all of the five star reviews, you will rate him with 5 stars as well when call him for service, I guarantee it!

done in a jiff…read more Sent out a request for a tesla wall connector installation via yelp. A reason why i went with this company is that they are licensed .... which i did double check and they do have a C10 which is for electrical. Also, they did answer with regard to how much a particular job would be. Originally, we had an after lunch timeslot... I requested if there was a possibility of a morning one the day prior... Thankfully, they were able to come on over and accommodate. So that's a plus. When they arrived, Nick was respectful and straight to the point. He pointed out some items that were needed to be addressed... and upgraded... Felt like an upsell but i do understand that when it comes to keeping a house safe, you gotta do what you gotta do and hopefully you get what you paid for. They offered to 1. do grounding.... 2. and also to install a surge protector.... 3. to change parts of the breaker that were damaged or cooked and not rated properly 4. Patch up the dry wall. 5. In addition to installing the tesla wall connector. Now originally, i just wanted to have just my tesla wall connector installed. The price for such is pretty affordable and comparable to other electricians. Unfortunately, with all the other things that needed to be done... the price exponentially increased. Good thing, they offered different modes of payment,.... like credit, debit, check, and even zelle. Since the bill was a pretty penny, he did mention doing a 60amp rather than a 50amp for the tesla wall connecter and making sure that all connections are up to code. I assumed from the beginning that it's supposed to be a 60amp since that is what the wall connector is rated for... In any case..... They got here at 8:43 am and were done by 10:07.... pretty quick and fast. I did like that Nick showed me the issues and also showed what they did and he assure me that everything is up to code. They sent an invoice via email and i paid them via check . Edit 2 weeks after: I have messaged them to cash the check i gave. They replied and promised that they will the following day but still hasn't ... i told them that I would be changing accounts .... Looking back, i think i should have asked for a breakdown of the services with the prices for each. They gave me an initial proposal of installation for a charge of : 300 usd. (50amp then 60amp) Then offered a surge protector for 350usd... Then said.... said let's make it up to code and charged me a total of 2,500.... for changing of fuses and putting a ground .... they didn't give a price but total was 2,500 USD. So i'm assuming that 2,500-650 =1,850 was for all that. Tbh, looking back... i felt that i overpaid...and upon asking around, apparently I did. I should just paid them for installation and that's it. And yes, they did ask for this review to be put out... hence, i'm editing it so that i'm writing it truthfully.
