Overview of SunLux

SunLux was started by 3 founders in very early 2015. They have been in the solar industry for nearly 10 years and have seen it all and done it all with over 6,000 installations under their belt. However, they had a vision to do things differently. They built a business model that is one of the leanest operations you will encounter. Why? It means SunLux can beat any price and still offer quality name brand components and some of the best looking installations you will find! Their focus is heavily customer oriented by staying in constant communication every step of the way. They built a model that will support the customer during the process and many years after! Founders of SunLux have seen it all and have over 30 years of combined experience. They founded SunLux to offer something different, a better kind of energy. They are passionate about solar and saving money for their customers, but more importantly improving the quality of life and the environment around them. They are also passionate about giving back to local schools and churches to better the community and make an impact on peoples lives. Restrict Competitors' Ads

SunLux and Solar Edge not a good combination

We paid Sunlux nearly $40,000 for a 35-panel SolarEdge system, and it has gone down multiple times. It is currently not producing, and none of the inverter’s status lights are illuminated. We received no monitoring warning when production stopped and discovered the problem only after receiving an approximately $800 electric bill. Sunlux said its service coordinator would contact us and review the system, but we received no response, diagnosis, or service appointment. SolarEdge also refused to assist us directly and told us to work with the installer, leaving us stuck between two companies while the system remains down. We own four other solar systems using Enphase equipment, and those systems have been more reliable and better supported. We may now have to transfer service to another solar company simply to get the system inspected and pursue an inverter warranty claim. Based on our experience with Sunlux’s lack of responsiveness and follow-through, I cannot recommend this company.

Delays, Unprofessional Conduct, and No Project Completion

SunLux led me to believe the installation would be completed by year-end so I could qualify for the 2025 tax credits. After signing in August, permits weren’t submitted until November, communication was poor, and the project stalled. During a phone call, their project manager became unprofessional and made threats stating my project could be intentionally delayed. Their delays made installation impossible and forced me to cancel. I continue to struggle to get responses and my deposit returned. I would not recommend this company.

Don't work with them. They will tell you your old roof is fine to install solar panels on. Then when it starts leaking under the solar panels, they won't fix it. Working on taking them to small claims court currently.

No customer service whatsoever

When thus cuando wants to sell you their system, they portrait themselves.as the best option.. once they get your business things change and to get a call could take literally forever. Not a very good experience with this company , watch out!!

UPDATE: 9/21/2023 Got solar installed through Sunlux with no issues and they even installed some consumption meters for me for free. Fast forward 6 years and my wife discovered a water stain on our ceiling. It's been a nightmare trying to deal with it and Sunlux has not helped. The wife discovered the issue on May 13th. I called them on the following Monday, May 15th. They couldn't find my information so I forwarded them my contract. They said they lost it during a data migration. They took down my information and called me back 2 weeks later only after I followed up with them regarding status. Two technicians came out on June 5th in the morning but WAS scheduled for the afternoon. I wasn't even notified, they just showed up at my door. They took our hose to the roof and started to look for the leak. They couldn't find any so they asked me to turn it up. I turned it to max which I think is 5 gallons per minute. They found a leak in one of my Ohagen vents and said that the leak was due to that vent and that they were not at fault. I went up to the attic where the other technician was and saw the leak with my own eyes but it leak was 15-20 feet away from where the ceiling stain was! I was speaking to Lorena saying that that leak is not the cause of the water damage. She said that it was and that I needed to hire a roofer. I asked her aren't you guys roofers? It says solar and roofer on your truck. So my wife took over the call and decided that we needed to hire our own roofer to find the source of the leak. To find the leak, the panels needed to be removed. Sunlux came out July 3rd to remove them. Our roofer came July 6th to find and fixed the leak that day. Sunlux came back out July 21st to reinstall the solar. For some reason they used one of the broken tiles I had lying around to replace another broken tile. I also noticed that there were 2 more broken tiles. The solar panels were put back but they look crooked. It doesn't affect productivity but that's not how it looked when they were taken off. And also the critter guard looks terrible as well. When we first got solar, they hired a company to install it and it looked great but now I think they are trying to install it themselves. I messaged Guillermo regarding these issues but have not heard anything other than that the critter guard clips are on backorder. The last I heard anything was on Aug 20th and as I write this review it's Sept 21st. At this point, I'm at a loss for words, I lost my trust and faith in Sunlux. They did take responsibility for the roof penertration leak although still felt very reluctant. Guillermo even came out to see the roofers fix the leak and still questioned how it could leak and when he left still said he needed to look at some pictures first. Sunlux did eventually take responsibility but the ordeal caused a lot of stress and anxiety. They did cut the check for the amount we had tonpay our roofer but the fact that they're not addressing my other issues is why I'm writing up this follow-up review. At this point, I probably rather not have them on my roof possibly breaking more tiles. I just hope that there aren't any broken tiles under the panels because I wasn't able to watch them put the panels back. But im guessing there is because I found some other broken tiles around the solar panels that they haven't said they will fix either

No power

My system was installed around 4 years ago. I upgraded and added 5 panels last year. Just had a $550 bill and a projected this month bill of another $500+ and after multiple emails, calls and service tickets over the past two weeks still no call or care to have someone come and look at it and fix it. They only seem to care about install and after that they just don't care.

Solar system lost 60% of it's generation in just 3 years. Sunlux has been completely unresponsive with support. I can't even get anyone to come out and look at my system.

Service ends at installation

Despite multiple communications over the course of 2 months, SunLux has not enabled the Wi-Fi system necessary for us to both monitor our solar generation and to confirm it is communicating to our utility company. SunLux left the inverter off after installation - something we had to find and remedy - and now have not responded for over a month to enable the Wi-Fi connection. Had I been wiser, payment would have been withheld until Wi-Fi and utility communication was validated. Fingers crossed a public negative review will prompt appropriate action.

So disappointed

From the beginning this company was doing an awesome job, from the first time we had a zoom meeting. The sales rep Chris was honest and I was convinced I have found the right solar company. That was back in November then LG went out of business and solar panels and the updated my panels to the new Teslas. Customer service my project manager was keeping me informed every week. Until March 25 when I called that were to be there for final inspection and nobody showed up so I call my project manager and she told me the city had canceled and supposedly the city called them. At 7:00 AM to notify that they expect to call in sick. So I decided to call the city of Norwalk I’m pretty familiar with the city permits in building and they told me I never had a had an appointment for inspection but they were willing to do it on Monday. So I call back my project manager and then she told me that somebody HRA call me on the 23rd to notify that there was no appointment for today. Well that’s a lie because normally they will email me or call me and any changes I have no email no calls. I have put complain and Penny and today is March 30 and I still have not received a call from the company Sunlux. They got their money I guess this is what I’m expecting if I ever have issues with my solar panels. I have a lot of family members and friends they were really to go with this company but now they hear my frustration and they’re planning to go on a different direction

I would give zero stars if I could

Completely unprofessional from the billing department to the sales department. The LG Monitoring system is an absolute joke.

Awful ... stay away

One star is too many ..... They are absolutely unprofessional . They gave me a bid and a timeline and it took 4 month to find out through the city expediter that SunLux design is faulty and it does not meet city standard , where we had provided them the exact requirements. Now after wasting so much of our time , they demand extra $5000 money for redesigning which requires more panel or stronger panel .. I ended up shopping the same with LA Solar whom are very professional and fast and demanded sunlux to refund my deposit and they did not . We took them to small claim court and they lost and up to day they are not paying whats owed to me so I am taking further action. Do your selves a favor and stay away from these guys

System not working, no call back

We chose this company because they had great reviews. There were some glitches in getting the panels installed, but that finally happened. They worked well enough for awhile, but stopped back in January. We didn't realize it until a couple of weeks ago, and put a call in to Sunlux and got a ticket number. We're still waiting to hear back from them. Mailbox is full, no return calls.

Sunlux ruined the structural integrity of our house

Sunlux cut through and removed the structural top plates of our home. They then tried to cover it with stucco before the inspector could come. Luckily my husband is in the trades and saw what they did. It has been 2 months with the structural integrity of the house compromised and the side of our house open to bugs and pests. Not to mention 2 more months without solar. They have not fixed it and they dont seem to care. I dont know what to do except warn everyone. Sunlux used to be the gold standard of solar, but I guess they no longer care.

Nightmare

So it took a little over six months to finally get our solar installed. They sent workers to our house working after 8:30 at night and the neighbors were calling the cops becuase of the noise. They also promised to send me a check for $452 dollars to compensate for the nighmare that we had gone through. Of course I haven't seen the check yet. This company does not care about getting the job done or making your neighbors mad at you.... they care about nothing but themselves. If you want solar, go somewhere else.

Bait and switch

Don't sign with this company they will give you a reasonable deal during initial talks, very responsive during this time frame. But after signing in the dotted line things changed drastically. A few days after signing I review notice via phone call the price of the equipment will increase 75% due to errors on behalf of the distributor. I email the owner requesting answer and have yet to replied to it has been over 3 weeks. My suggestion to all that read this is to go with a different company any company. They had the nerve to force their distributor to call me instead of responding to me direct. Still awaiting answer and a resolution will update once I get one? But as for now don't make the same mistake I did.
