Sunlux panels and equipment

Sunlux specializes in residential and commercial solar energy installations. It partners with a few quality brands to offer solar panels, inverters, batteries and EV charging solutions.

  • Solar panels: Aptos, REC and Qcells
  • Solar inverters and microinverters: Tesla inverters, SolarEdge inverters and Enphase microinverters,
  • Residential battery storage: Powerwall, Enphase and SolarEdge systems
  • Commercial battery storage: Tesla Megapack, RCT Power CESS 200 US systems

Sunlux installations

Sunlux handles design, permitting and installation in-house (unlike some solar companies that only sell contracts and outsource the work). The first step in the process is to book a free consultation to determine if solar is right for you.

  1. Consultation: The installation process starts with a visit to the location, where specialists survey for challenges and measure the available space.
  2. Planning: Within the following week, Sunlux designers draft a plan that matches your desired aesthetic and efficiency.
  3. Permits: The company then applies for permits. Permit approval may take up to a month.
  4. Scheduling: Once the permits arrive, the company will schedule an appointment to install your new solar energy system.
  5. Inspection: After passing inspection and receiving utility approval, energy production can officially begin.

Sunlux costs

Solar panel costs vary depending on the size of your roof and whether you purchase, finance, lease or prepay for your solar panels. On the high end, one Sunlux customer, Aldo in Corona, told us he spent $80,000 on a system.

Statewide, typical solar panels cost in California range $12,224 to $24,449. But homeowners rarely have to pay that much upfront, thanks to affordable financing and leasing options.

It’s best to get a personalized quote for the most accurate cost estimate. Sunlux offers a solar calculator that can help you estimate the cost of your solar system and utility cost savings over time based on your average monthly utility bill.

Sunlux payment options

Sunlux offers several different options for its solar energy systems:

  • Purchase: You can buy the system outright. If you decide to purchase, there is a $1,000 deposit upfront. The remaining balance is typically due when installation begins.
  • Finance: Sunlux partners with a few loan companies to offer $0 short- and long-term payment options.
  • Lease: With solar leases, you pay nothing upfront. Then you pay a fixed monthly rate over a 25-year agreement.
  • Prepaid lease: This option lets you prepay a locked-in rate for the electricity your solar energy system should generate over the next 25 years.

Sunlux warranty

Sunlux offers 25-year coverage on equipment, with additional warranty options that can include performance guarantees.

Sunlux also provides access to 24/7 monitoring platforms to its customers. This will let you check on the performance of your solar system and notify reps of any issues with your system that may arise.

FAQ

What is Sunlux?

Sunlux is a solar energy company that designs and installs solar systems for homes and businesses. It operates primarily in Southern California and is a certified installer for brands like Tesla Powerwall. Because it manages projects directly, customers typically have one company responsible for the entire installation process.

How long do Sunlux installations take?

Installation typically takes one or two days, though permitting and preparation can take several weeks to a few months.

Where is Sunlux available?

Sunlux is available in Southern California.

When was Sunlux founded?

Sunlux was founded in 2015.

Is Sunlux legit?

We consider Sunlux a legitimate option based on strong feedback from verified customers and the range of financing options it offers.

Some customers report predictable monthly payments compared with fluctuating utility bills. Christian in Rancho Palos Verdes said his financing payment was about $150 per month for six years, after which he would own the system outright.

Other reviewers mention a detailed installation process. Daniel in Wildomar appreciated the thorough site assessment, saying his representative “showed me how extensive their installation process is to prevent roof leaks.” That kind of upfront evaluation can help protect your roof and avoid costly issues later.

However, not all experiences are seamless. Robina in Paramount said that while her salesperson was responsive, she felt some important details — including roof compatibility — were not clearly explained upfront. She also described communication during the process as confusing and said she was reconsidering moving forward.

As with any solar company, homeowners should review contract terms carefully, confirm roof requirements early and compare multiple quotes before signing.

    I did at least half a dozen different companies like Tesla, some of the smaller guys, and then Sunlux before I had taken a look at the bigger guys. When I took a look at those guys at Costco, they just wanted an incredibly high amount for the same size system. Generally, I was hoping to be able to save a little bit of money and to be a little bit of an environmentalist.

    Sunlux was good. The biggest hard part was just waiting for all the things to come through, basically waiting for building and services to approve the permit. And for the most part, it seemed like it was fairly easy. I was hoping to get it installed last year, but wound up getting it this year. But part of that was because of the age of my roof. It was at 30 years, and so given that, there would be a good chance that I'd be having to take the panels off and replace the roof halfway through, certainly within the next 10 years. And so we wound up doing a lift in relay and Sunlux was great in helping me with that.

    Installation of the panels was easy. Once we got the roof on, they came out one day and prepped the roof with all the parts for the panels. They had to wait because it was really windy, so we wound up waiting for about a week. And they came out and got the panels up, and it went smoothly. There were no real big issues.

    They were also easy to talk to. The project manager was a bit busy. It was a little hard getting information from him, it sounded like he was managing multiple projects. Maybe I was too involved. If I had questions about something, it would often take the project manager a couple days to get back. I'd email them and then it would take a couple of days to get back, which may not be that big of a deal. But it seemed to be a little slow. It's like he was really busy with everything going on. And maybe it might help if they had a second project manager. I found my best conversation was when I went through and talked to the accountant in trying to get things done.

    I'm tracking it via an app through Enphase converter, and so far, what it's suggesting is that I'm producing over two times the power that I would do on an average daily basis, based on my period from November through January.

    Everything they did was great. The biggest thing that I liked about them is they had different options between panels, and they were happy to give them to me. With Project Solar, when I was first looking at them, they wouldn't tell me about other panels, but I would at least be able to ask them to see what they had.

    I got the REC 420 panels. After 25 years, they're supposed to be able to still produce 93% of their original rated power compared to the Tesla panels, which is like 80%. I'm guessing a lot of panels probably come in around 85.

    It was 25 panels, and we estimated somewhere between 11,000 and 12,000 kilowatts a year, and we figured we'll go up to about 106%. I think they're capable of doing 15 kilowatt-hours, but we wanted to go a little bit more because I wanted to eventually add an induction stove/oven. And as it turned out, I just had to add a heat pump. He left our heat pump, which was unexpected. The heater that I had in there was 20 years old, and I'd have the thermostat turned off, and for some reason, the heater would try to turn back on. So, I'd have to unplug it, let it reset itself, then plug it back in, and it would be okay.

    And ultimately, when they checked it out, they noticed that the board had some shorts on it. You could see some discoloration around the different pieces that indicated that it was shorting out. It wasn't so bad that it could work sometimes, and so I'm like we can wait a year before we do it until we get the tax return.
    Other than that, I found it very easy. At one point, I almost went with Tesla. You do everything via the website, and if you get one thing wrong, you're screwed and you can't even talk with them. And that's why I eventually didn't go with them. But as it turned out, the panels I got on my roof were a lot better. I’d definitely recommend them to friends.

      We're in Portuguese Bend. All the utilities have been cut off so I decided to go solar. I like Sunlux and have had them for about six months now. It was easy and straightforward when I got it installed. That is our electricity, so there is no billing. We're very happy about the quality.

      I chose Sunlux due to the reviews of all the highlights that they had. When we went with them, the company they were working with prior, SunPower, went under, and they were bought by Sunrun, and then everything got lost in the shuffle. When the system actually got put in place last November, it didn't work. The guy came out last week, and hopefully it's working now. But I had to pay $500 for my Edison bill and $200 to Sunrun for a system that did not work. It's been really frustrating.

      I would love to pay for something that works. Every time I reach out, it's always, "Well, Sunrun has now taken over your system." But in reality, it's never worked from the start. So, I wish that Sunlux stands up to their company's reviews, finds their values and really fixes this problem. Because it's been really awful to spend $80,000 for a system not to work.

      I had water come through where the panels were installed. I looked at my contract. Looks like I was covered with the 10 year warranty on leaks. I called, explained what was going on. They sent someone. They found broken tile and repaired them and told me problem solved. Well 1 week later rain. More water came through. Worse than the first time. Again I called. They said they will take care of it. It's been 2 years and now they are just straight ignoring me. The drywall inside the house is damaged and they don't want to take any responsibility for it. I've waited so much time with this. It's a shame because I have people asking me all the time who did your panels and I have to be negative with the referral. I can't refer my neighbors and friends to these people.

      The Sunlux rep sounded like he knew what he was doing. I bought the solar panels outright. The installation was not quick because of California adopting new net metering rules. So, there was a big rush to get in under the changeover. There was a four-month delay between the initial contact and the installation. The solar panels are working. It has a good return on investment.

      Sunlux is good. I don't have a problem. There was a good tax rebate going solar, and my electric bill was high. Sunlux had the most customizable plan. It could fit on my roof. They got more panels on my roof. Their reps are very stellar. They all get back to me. Everyone was good. I had to finance the panels and the process was easy. Sunlux referred a couple of different people, and I ended up going with one of them. Installation went quickly. We were up and running a couple weeks after that, and it's been active now for a year and a half ago. It looks like I'm saving money. I haven't really run the numbers, but it's like I'm saving 200 bucks a month. I'd tell someone to give them a shot. They're a good company. I like working with them.

      I recently had Sunlux Solar Companies install a solar system for my home, and the experience has been outstanding from start to finish. The installation team from Sunlux was top-notch. They were professional, efficient, and very knowledgeable. The pricing was competitive, and Sunlux offered a variety of financing options that made the investment more manageable. Sunlux also provides a robust monitoring system that allows me to track the performance of my solar panels in real time.

      I would recommend Sunlux but make sure you get a completion of work so they cannot put a lien on your property. Having the solar put in was smooth. Sunlux took care of everything. But in doing so, we needed to get our roof done. Sunlux recommended a certain company. We went through them and did the financing through Sunlux for the roofing company. Everything went great. But within a few months, the company Sunlux used didn't pay their supplier, so they put a lien on our property. That was when we went to Sunlux to contact them saying, "We're paying you for the roof. Everything's fine. Why are we now having to deal with all of this drama?" The roofing company went bankrupt. I understand it wasn't Sunlux's issue. But at the same time, we were financing and paying Sunlux, so Sunlux paid the roofer. Why did we become the middle person?

      When we tried to reach out, Sunlux just corresponded with an email. There was no person to help us navigate that as we went through it. We got it taken care of. But it took almost a year. Everything up until that point was great. We've had two issues with retrieving the power. Sunlux took care of it. They have gone down and they sent an email, "Something's going on." And the next thing I knew, the email was, "It's been resolved." Going solar lowered our bill.

      I interviewed several people and Sunlux had the best price and their solar energy system looked like a good product. We interacted with three bidders and Sunlux came out, looked the situation over and evaluated what product we needed. We took out some paperwork and we were off and running. Everything was straightforward.

      The installation was a little rougher but they established a schedule for installation. We had to change the power panel so that was part of the changeover. We had an inspector who was a pain in the behind and kept kicking back problems but Sunlux worked through that. When they brought the panels out, three had been damaged during transit. So, they replaced those and it all went smoothly. It was an excellent quality service compared to the cost. I have the app and it shows me what's happening with the panels and it’s very good. I would recommend Sunlux. They have people behind them who know what they're doing. They did a nice job and worked well with the power company.
