What does Sunlux do?

Sunlux designs customized solar energy systems to ensure they fit its customers' needs. Sunlux's systems consist of solar panels, solar inverters and batteries. The company takes pride in its partnerships with Tesla, Panasonic and LG, which lets it build quality systems from quality materials. Sunlux provides cost-efficient, renewable energy sources, and customers can expect excellent engineering and professional installation. Sunlux also provides a handy savings calculator that estimates immediate and lifetime savings, which helps customers make educated financing decisions.

Sunlux costs

Sunlux prices range from $24,900 to $35,000. Costs vary depending on the size of your roof and whether you purchase, finance, lease or prepay for your solar panels. If you decide to purchase, a $1,000 deposit gets the process started, and the remaining cost is due after the company installs your solar power system.

Sunlux regularly coordinates with clients to find loan options, working with partners such as Dividend and the Energy Loan Network. Federal tax credits are also available to lower construction costs.

Sunlux installation

Sunlux solar installation only takes one or two days, but the prep time can take up to six weeks.

  1. The installation process starts with a visit to the location, where specialists survey for challenges and measure the available space.
  2. Within the following week, Sunlux designers draft a plan that matches the customer's desired aesthetic and efficiency.
  3. The company then applies for permits. Permit approval may take up to a month.
  4. Once the permits arrive, the company begins installing the solar energy system.
  5. Crews install mounts and wiring first and then attach panels on the roof.
  6. Once finished, the system must pass a brief legal inspection. Then, energy production can begin.

Sunlux warranty

Sunlux offers a 25-year warranty, which is long by industry standards. The warranty covers the panels, performance, maintenance, installation and parts. The company also guarantees energy production, which lets customers know the system will continue to produce the desired amount of energy. Sunlux also includes monitoring, which lets customers check on the performance of their solar power system.

Southern California Edison has changed the net metering. The amount of money that Edison buys the power from people with solar panels is going to get cut by 75%. If you don't have your solar panels approved by Edison before April 17th, whatever Edison pays to buy power from people with solar panels gets changed by 75%. So, it would be more cost-effective to do it now. If we waited until after April 17th, people are saying it's gonna kill the solar industry in Southern California because Edison's not gonna be paying homeowners for the extra energy that they produce. So, we felt compelled to have solar panels installed because of the Edison deadline. So far, Sunlux hasn't started any work except process paperwork. So far, processing the paperwork has been fine.

Edison approved the location of my meter. We're gonna get the meter changed out because it doesn't support the solar system. So, they're gonna put a new electrical panel box in where the meter goes. In order to do that, they have to get Edison's approval for the new location. So, they put a sticker on my existing box saying it's ok to put the new one in the same spot. It's procedural thing with Edison.

So far, I had no problem with Sunlux. I had a question for the project manager, and I emailed them. They called me right away. There's really no problem getting questions answered. Saving money on the bill is kind of irrelevant because we're paying for the panels. So with the cost of the panels versus just paying the electric bill, I save a few hundred dollars a month versus my average electric bill. That's all I'll be saving for the most part over the next 20 years. The money I would spend to pay my electric bill, I'm paying for solar panels. I'm not saving any money. I'm just moving it from Edison to the solar panels.

    Things have generally gone okay with Sunlux and the only thing that is disappointing is my project manager is out in Texas and I live in a three-story house and they keep saying that there are things that are preventing the project from going to the next level. So, I'm trying to see if they can complete the project work-up so then it can go to my HOA. It's stalled out a little bit. So, I'm waiting for Sunlux to take the next step. Everyone on the team seems to be receptive and seems to be trying to do their best to provide appropriate services. But every month that goes by that I don't have solar panels on the roof, I'm losing money because that's money that I'm paying into a power bill that I wouldn't necessarily have to pay. So, Sunlux is in a tough spot because the faster they get the solar panels up, the happier the customer is. So, I'm just sitting here watching the clock.

    We're just starting this process and there's still gonna be many steps left. So, if six months goes by and there are still no solar panels, I'm out a couple of $1,000 in solar savings. Six months from now, if we get to a place where things are not moving forward appropriately, I'm gonna be upset. But right now, things are good. We're only a month In so there's plenty of time. I'm flexible. Generally speaking, I'm happy.

    The very first guy I talked to was incredibly helpful and knowledgeable. He had worked in the industry for many years and in many positions. But it seems like we're kind of getting stuck here as far as the next step because it can't go in in the original configuration that everybody thought it was going to be. So now they're trying to come up with some alternative. But I haven’t heard from them yet. It seems it's going to be more expensive, and it makes sense because it's more trouble. It's going to cost as much as it would cost to have power from the power company. So it's going to die down even though I'm getting the break on the taxes. If only it's going to work.

    Sunlux is trying to do an upsell. They think I need to replace the electrical panel. The difficulty is that this house was built in 1961. It has the original electrical panel in it and there is no more label on the panel that contains the detailed information that they say they need to calculate the amperage load potential of the busbar, which is where all the power goes through. They can do that math, but they're not willing to. They want to upgrade the panel and that's another four grand. I don't want to do a panel upgrade and we don't need it. But Sunlux said the inspector could give them trouble. They can identify the panel through the breakers, but they won't do that. I can understand they're trying to avoid trouble and it is an extra mile to go. But sometimes you got to do the extra mile.

    We heard about Sunlux through a friend who used the company and specifically put us in touch with Chris. We called him and it was great. We liked how easy he explained everything really well to us. However, we had a little bump recently. My husband was home, and whoever came out to do the site audit didn't talk to my husband. In one of the emails that came through, I was a little confused because I wasn't sure exactly what the representative was asking us. I sent a clarifying email, then after that, the email that she sent back was a lot more clear. She was asking us about where we're gonna put the EVs. We're going back and forth now through email, trying to finalize where our EV outlets are gonna go.

    Nothing's been installed, but so far, Sunlux has been great. They're very responsive. If there’s anything, it's us on our end that has been lagging behind. There is a lag time in between when you’re communicating through email, and it’s hard. One time, my husband and I were like, “Well, did you answer?” “No, I thought you answered.” It took longer than we wanted it to go, but we try to respond quickly and Sunlux always responds quickly back to us.

    I have two houses down Corporate with Sunlux. One is okay and we are already processing through the HOA. But the scheduling with the other one is quite slow. They arranged for the technician to take a look at the roof, then after he inspected the roof, I haven't heard anything from them for four weeks. Later on, they contacted me and said that the technician did not complete an investigation on the roof. So they needed to come back again. Then they started to schedule for the technician to come over. In the end, I contacted the salesperson who contacted me in the very beginning. He contacted someone in the company and arranged for someone to come over today to take a look at the roof again. He did a good job. In fact, he is the reason why I chose Sunlux. This guy is Chinese, he's very popular in the Facebook group, and a lot of people recommend him, which is the most important thing.

    Sunlux response

    Hi Ben,

    I apologize for any delays and will look into this immediately.

    Sunlux had the best sales process. Christopher, was our sales guy and he was really great and his presentation was great. It was very clear. The other kicker at the end was they had better financing options available. The installation itself was fine. A little damage to the house, but they came and fixed it afterwards.

    The electrical bill has been small. We're still in the process of switching over. It's only been a month or two that we had our permission to operate. But the biggest issue we're having right now is some of our other electrical devices are not working very well because something wasn't done correctly during the panel upgrade. The AC has not been working for about two weeks, and the washing machine is intermittent. We have to go out and flip the breaker.

    Sunlux response

    Hi Brian, I wanted to follow up on this review to make sure that we are taking care of the issues. I looked at the notes and it does look like we have been back to your home and the AC issue has been corrected. Can you confirm?

    Sunlux came in with a price that I was willing to pay. Also, their reps were very responsive. But I ran into a bit of an issue last year when I was trying to expand the system. I sent them emails, but they wouldn't respond. It seemed their spam filters were stopping me from emailing them. We eventually talked on the phone and got past it. So, they completed the expansion of the system last month. It all worked out. There is a reduction in what I pay the power company. Give Sunlux a shot.

    The reps were informative. They weren't trying to push something on me. The experience was pleasant. From the initial sign-up, the information that they provided, the non-hassle attitude and what they had to offer as far as price, Sunlux sold me on them.

    In the beginning, the process was very simple online. I had a shared screen meeting so that we didn't have to disrupt anything. Then the site inspections came. At one point, we had some roof leaks and some delays, but in the end, the individuals involved got everything taken care of. So, I appreciate it and the system has been a great benefit. Going with them was definitely a smart decision.
