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. read more

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. read more

They installed my solar system and powerwall 3 a year ago. It wasn't the smoothest process, Tesla had to send back a new powerwall because there was an issue with it but Sunlux handled it and kept showing up until it was fixed. System runs great and have had zero issues, beautiful install and would definitely recomend them. read more

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! read more

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. read more

My husband and I got our solar installed with SunLux. Process was easy and got it done in a timely manor. We even had them come back out to install our back up battery a Tesla power wall. We want to make sure our food doesn't go bad if and when there's a power outage. We are happy with our purchase and recommend them to all of our friends and family. read more

This company is very good at front end sales and terrible at monitoring and customer service post install. Customer now for almost 7 years. Our system was completely offline at one point for months and no one at the company alerted us. We recently noticed that power generation is way down and has been for months and again, there was never any alert from the company. We paid the additional fee for the power generation guarantee and recently after digging into our contract realized they have not fufilled their obligations under agreement. We've initiated a dispute process, and I'm worried this is going to require a lawyer. When dealing with them it's clear that post install customer service is an afterthought and no real team or process is in place to properly monitor systems and proactively address system issues. This is a sales and install company first and foremost, leaving their customers substantially unsupported afterwards. Find a company that will actually help you monitor and maintain your very expensive solar system or it becomes an even more expensive investment and you will regret it. read more

Wow, do you know when you just made a bad choice and have so much regret. That is exactly where I am with Sunlux. I am completely embarrassed to have chosen them. Mike VP of sales will have a very nice presentation from Austin, Texas. You will feel confident and secure moving forward. While the professionalism and quality of work is just embarrassing here in CA. Don't want to bore you with all the install issues, extended timeline and being ignored. Being ignored is just so disrespectful and insulting. Especially when you have already paid for the project. That is so troubling and a red flag, that is when I knew, but it was too late. I will tell you after six months my system is finally up. To add insult to injury the courtesy emails that come in after the install have links that are expired and are effectively useless. Wow, way to confirm my thoughts and review. These emails are coming from the executive team out of Austin, TX. Leadership trickles down, this explains so much about the culture of the company. I see Chapter 7 & Chapter 11 in their future. That leaves me with warranty exposure, but I am already planning for them to go out of business or restructure. If they don't then I will continue dealing with them. If they do, well I wouldn't be surprised. In close, this was a full cash purchase paid in full. Good luck, be warned. read more

Original installation was poor, they made a couple mistakes but to their credit, they corrected the issues. Been working fine for almost 6 years but solar edge app made a change in january and my app is not working followed all instuctions, hard reset ect. still no connectivity said to call installer, that is SunLux, this customer service number they are not returning calls....i have been trying for a week. Hopefully they will read this and call me read more

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. read more

Sunlux put my solar in about 5 years ago...and I wish I never did it. My bills have barely changed and the cost of the system was over $60,000. Their follow up and service as a company is non existent. They do not stand by their warranty, don't follow through with repair requests and really don't care if the system they install works as originally promised. On top of this, the LG panels they installed are no longer even produced. Run from this company! read more

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! read more

***WARNING!!! Sunlux is an unprofessional, unethical, and fraudulent solar company!!! They are currently under formal investigation by the CA Contractor's State License Board (CSLB) for multiple violations of state law, multiple violations of building codes, multiple breaches of contract, and multiple counts of fraud! My solar expert says that my Sunlux solar installation is, "the worst solar installation he has seen in over a decade"! (All he does is solar lawsuits, complaints, and solar fraud). Sunlux is also full of "professional liars". They pretend to cooperate and address their unprofessional problems, but their unethical and fraudulent actions (and lack of action) speak louder than their lies. Their performance guarantee is also practically worthless, especially since they will probably be going out of business. read more

Customer service and communication simply do not exist unless you are a brand-new customer. I need to find another company that can provide service as soon as possible, because my unit needs repair. Unless they are so busy that we are expected to wait several weeks just to get a call back, this is unacceptable. read more

My experience with Sunlux was OUTSTANDING from proposal to installation. Mike was patient and willing to answer all my questions and concerns during the proposal phase. The communication with the project managers, inspectors, and installers helped make it a smooth experience. Jessica, project manager was very helpful during the install and inspection phase answering questions and assuring the process would go smoothly. I would definitely recommend this company to anyone who is interested in solar Thanks to everyone at Sunlux for wonderful experience. read more

Service and installation was a great experience. Looks super clean on my roof just overall quality and value.

After interviewing 5 other solar companies including two of the largest in the country, I decided to go with Sunlux. I spoke with Mike and he was able to beat all the offers from the other major solar companies. He was honest and tailored a system that fit my needs. Communication with Mike from start to finish was outstanding. One of the largest solar companies in the end was able to match and slightly beat the offer I received from Sunlux, however I still decided to go with Sunlux because of their reviews, their honesty, and the great communication that I received from Mike. Fast forward to now, the stage where the electric company connects their meter to the solar system, their tech unfortunately broke the meter socket in my home and I was left without electricity until it was repaired by a licensed electrician. Guillermo from Sunlux came to the rescue in no time and sent one of their electricians to fix the broken socket in my home. The communication and honesty from Guillermo mirrored that of Mike. He has been a pleasure to communicate with and I am very happy with Sunlux as a whole. I am glad that I went with them, as they have taken care of me and my needs, with diligence and honesty. My system is almost live, I'm just waiting on the electric company to come back and put in their adapter on the meter so that we can go live. I am confident that I will remain a happy customer thanks to guys at Sunlux like Mike and Guillermo that truly care about their customers. I highly recommend them due to their communication, honesty, and the value that you get from them. read more

My inverter they installed is faulty and giving error codes. Been trying for several days to contact them. Voice mailbox is always full, they don't answer the phone and they don't respond to emails.

From beginning to end Mike and team were very informative on all stages of the project, Best part I'm saving hundreds every Month with the system, you need to get this system! read more

Around April 25, 2025, Joey, a Sunlux Tech., came out to my home to help finish the Tesla Battery install. Anytime I came out to see the progress, Joey was more than available to explain the operation. Joey was always friendly, & cordial in his explanation of items installed. Even though, I'm technically challenged, Joey took his time to bring it down to my level of understanding. I have to include other Sunlux individuals that made this all possible from Mike Valencia, Adam Cunningham, Gabriel Benko, & Jessica Britzman. These are all important responsible people who work tirelessly behind the scenes to make this happen. The Value of this company for your Solar needs is so necessary for worry free Solar operation. Give this company a chance to meet your Solar needs. We will have more sunny days than rainy ones. Electricity is like GOLD here in CA. Edison will NOT lower the costs. It'll only go UP! CA. has more EVs than any other state. That takes electricity too. Think about it. Chuck Frederick Redlands, CA. Southern California read more

After writing my review below, I did hear back from the exact technician from Sunlux that had installed my panels over two years ago. He was very helpful, and provided me with fairly easy to follow YouTube videos. He also said if needed he would come back out in person. I am confirming that I have been able to reconnect my solar system to my new home network after following the self help video shared by the Sunlux installer. Two years in from my purchase and installation, I am having problems with connectivity and monitoring of my panels. Sunlux directed me to reach out to the manufacturer for support. The manufacturer stated it was the installer, Sunlux's , responsibility to provide support. My contacts at Sunlux have blocked my email after my initial contact for assistance. I have no resolution after nine days. Very poor customer service experience initially. read more

Shopped 7 solar installers, chose Sun Lux. Worked with Mike who made the process very easy and broke down each step.

I have given an excellent review previously, some 2 years ago. But things change. There was wiring that became exposed. My electrician, there on another matter, pointed it out. Told me to call Sunlux to get it fixed. I did so. Now all I get is excuses and justifications from Gabriel Benko, the Director of Operations, in stead of solutions. Like another review by Avin S. Great install, super staff and helpful installers. Yet poor customer service after the fact. read more

My solar inverter broke down so I had to replace it. Since it was under warranty Sunlux claimed it with Solaredge since they are the manufacturer of the inverter. However, Solaredge was very slow in getting me the new inverter replacement. Initially, they told me it will take 2-4 weeks to get it. A month and a half later still nothing. Every time I called Solaredge they gave me the run-around. Finally, Lorena Gutierrez from Sunlux stepped in and told me they can give me one of their new inverters first while I waited for my replacement and then give them my inverter once I received it. They came 2 days later and replace my inverter with a new one. I want to thank Lorena Gutierrez from Sunlux to do that for me. Now my solar is working great!! I definitely recommend Sunlux if you are still looking for a great solar company. read more

I contacted Sunlux along with several other companies when I was looking to add battery backup to our existing solar system. Sunlux recommended the latest version of the Tesla Power Wall and they offered the best pricing for the equipment and installation. It took about 2 months from start to completion. That included approved permit. The techs and support staff were all professional and knowledgeable. I could not be happier with the installation and the Tesla Power Wall. The Power Wall supplies all of our electrical needs through the night when there is no solar production. By morning it is a short time when it is back to 100% charged. We have had two power outages and the power wall took over. I am the only house on my street that has electricity. I can highly recommend this company for your solar battery backup needs. read more

We are very happy with our Sunlux Solar System. Combined with our Tesla battery we are supplying our home with power without using SCE and are selling power back to the grid everyday.

Kurtiss the crew lead was awesome and answered all my questions I had and walked me through the process of solar. He also did very well on the electrical. The roof lead Omar and his guys Ricardo & Alex on the other hand had done mediocre work. For 3 guys and licensed roofers I expected better work. There was a lot of debris left on roof, broken tiles exposing sheathing, solar panels not leveled and crooked. Glue and scratches on the solar panels themself. Expected better from sunlux. UPDATE: Kurtiss came back out and fixed all the roof issues and everything is perfect. He even painted the old vent stacks flashings which he didn't have too but still did to make the roof look better. read more
