Sunlux costs

Sunlux prices vary depending on the size of your roof and whether you purchase, finance, lease or prepay for your solar panels. The company 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 and your state.

If you decide to purchase, you only need to put down a $1,000 deposit to start the process —the remaining cost would be due once the installation of the solar system commences.

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

    I was hoping to be able to save a little bit of money and to be a little bit of an environmentalist. So, I decided to go with solar energy. I compared several companies, including Tesla and some smaller providers, but ultimately chose Sunlux Energy due to their better pricing for the same size system compared to the bigger companies. The enrollment process was straightforward although there was some waiting involved for permits from building and services. Originally, I hoped to have the system installed last year, but due to the age of my roof, I ended up doing a lift and relay which Sunlux helped facilitate. Once the roof work was completed, the panel installation was smooth. Sunlux came out and prepped the roof and, after a short delay due to weather, installed the panels without any major issues.

    Now that the system is up and running, I track my solar production through an app connected to the Enphase converter. I'm quite satisfied as it shows I'm generating more than twice the amount of energy I typically use daily during the November to January period. In terms of customer service, interacting with Sunlux was generally easy, though I did experience some delays in getting responses from the project manager. He seemed quite busy, which slowed down communication at times.

    Nevertheless, I'd still recommend Sunlux to friends and family. What I especially appreciated about Sunlux was the flexibility they offered regarding panel choices. I ended up selecting REC 420 panels, which are expected to still produce 93% of their original power after 25 years, outperforming other options like Tesla panels. We agreed upon a setup of 25 panels, aiming for a generation slightly over my current usage to accommodate future appliances like an induction stove and a heat pump. Overall, Sunlux met my expectations, and I'm pleased with the decision to go solar with them.

      I live in Portuguese Bend, where all utilities have been cut off, and I decided to go solar with Sunlux. The decision was straightforward as I found them likable and reliable. The installation process was easy and straightforward. I've had the Sunlux system for about six months now, and I'm very pleased with the quality. We're using the system solely for our electricity needs, and as a result, we don't have any billing, which is fantastic. Overall, I'm very happy with Sunlux.

      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 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.

      I recently had the pleasure of working with Sunlux for a solar panel installation on my home, and I couldn't be happier with the experience. From start to finish, Sunlux demonstrated professionalism, expertise, and exceptional customer service.The initial consultation was thorough and informative. The representative took the time to explain the benefits of solar energy and how Sunlux's systems work. They provided a detailed assessment of my energy needs and designed a custom solution that fit my home perfectly.

      The installation process was smooth and efficient. The Sunlux team arrived on time and completed the job within the promised timeframe. They were respectful of my property, ensuring everything was cleaned up once the installation was complete. The quality of the workmanship was top-notch, and the panels look great on my roof. Since the installation, my energy bills have significantly decreased, and I feel great knowing that I am contributing to a more sustainable future. The performance of the solar system has exceeded my expectations, and I appreciate the ongoing support and monitoring provided by Sunlux. Overall, I highly recommend Sunlux to anyone considering solar energy. Their commitment to quality, customer satisfaction, and environmental sustainability is truly commendable. Thank you, Sunlux, for making my transition to solar energy a seamless and rewarding experience!

      Installation & SetupTech

      Reviewed Feb. 22, 2025

      My experience with Sunlux Energy has been terrible. We had our system installed in November, and as of the end of February, it was still not functioning. I chose Sunlux because of their positive reviews, but during my process, the company working with them, SunPower, was acquired by Sunrun, leading to a lot of confusion and issues. Even after installation, the system didn't work. A technician came out last week, and now it might be functional, but I had to pay $500 for my Edison bill and $200 to Sunrun for a non-working system.

      Installation itself was fine and completed in a few days, but since the system never worked, it was a bad experience. I wish Sunlux would live up to their reviews and address this problem because it has been awful going through a company, spending $80,000 on a system that doesn't work. I can't recommend them to anyone, even though people often ask me about it. I tell them not to choose Sunlux. My dissatisfaction is definite, and if I had to rate it, they would get a one out of five.

      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.

      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.
