SunPower services

When you purchase a solar system from SunPower, the partner will help you prepare documents for homeowners association review and obtain all the necessary permits.

After installing the system, the partner arranges for inspections and helps you obtain “permission to operate” orders from your utility.

Once your system is up and running, the SunPower Monitoring System (EnergyLink) gathers data to help you monitor and track your estimated bill savings. If you need help with anything, you can contact SunPower customer support Monday through Saturday.

SunPower solar panels and equipment

  • Monocrystalline Solar Panels: SunPower installs high-efficiency monocrystalline panels. These panels are known for their superior performance and durability.
  • Microinverters: They utilize Enphase IQ7+ microinverters, which are installed on each panel to maximize energy production and provide real-time performance monitoring.
  • Solar Batteries: SunPower offers battery storage solutions, including Tesla Powerwall and FranklinWH batteries, allowing homeowners to store excess energy for use during outages or peak demand times.

SunPower solar panel installation

SunPower partners with dealers and installers nationwide to complete the design and installation process. These partners have all completed training and are SunPower-certified. The company incorporates a sleek, minimalistic rooftop design by using a low-profile mounting system called InvisiMount. This system uses durable metal wire clips to keep cables out of sight.

SunPower costs

SunPower found that a 5-kilowatt solar system typically costs between $11,150 and $46,100, which breaks down to $2.23 to $9.22 per watt. This price is before any tax credits or solar incentives. Since the costs can vary so much, the best way to get an accurate quote is to contact a SunPower dealer.

The cost of a SunPower solar system depends on several different factors, including your:

  • Energy needs
  • Local weather
  • Roof layout
  • Roof shading
  • Size of your system

While SunPower may cost a little more than other solar energy companies, its high-efficiency solar panels and transferable warranty may make it worth it.

SunPower financing options

SunPower offers solar financing options with $0 down for eligible homeowners. With SunPower, you can purchase a residential system outright, pay with a loan or lease a system.

While leasing a system lets you take advantage of solar energy without a long-term commitment, you’ll need to purchase the system to take advantage of any tax credits and other solar incentives.

SunPower warranty

The SunPower Complete Confidence Warranty covers any repairs or replacements to the components on your roof for 25 years. This includes the microinverters, racking and solar panels.

All components not on your roof have a 10-year warranty. This includes your storage and monitoring systems. The warranty covers shipping and labor with no additional out-of-pocket costs. However, the smartphone and computer you use to monitor your solar panel production aren’t covered.

SunPower also guarantees your solar panels won’t lose more than 10% of their original power output in that 25-year period, which ensures your solar energy system stays efficient and produces the solar power your home needs.

The warranty does have some exclusions, including:

  • Damage from natural forces, such as a tornado or earthquake
  • Defects of the home’s existing electrical components at the installation site
  • Damage caused by animals
  • Damaged caused by third-party products
  • Storage systems kept in temperatures outside the specified range

SunPower video review

sunpower solar company video review
Rick: Hi, my name is Rick, and I live in Ponte Vedra, Florida. And what got me into solar power was two things. One was financial. Wanting to not have to pay an electric company for my electric bill. And the other was being a responsible caretaker of the Earth, I suppose. To be green. So we didn't really choose a lot of alternatives. I did my studying on the internet very thoroughly, and quickly came across SunPower. And through peer-reviewed information and studying, I found that they were the best product on the market. That's why we went with them, and, quite frankly we're very happy with the product because it is a wrap-around product. They have everything from the connectors to the electrical. If there's ever an issue with it, I can just go to SunPower. I don't have to rely on a third party contractor for anything as far as a systems concern. So we're very happy with our purchase. So the purchase process for these solar panels is very simple and very easy. The representative came to our house and explained the options we had available to us. We chose to go with a loan to finance the panels over 25 years, and it was very simple, very straightforward and direct. We'll be using the tax credit to pay off a portion of the loan this year, and after that, it's a 25 year loan. And I pay extra on it, and we're very happy with it. No problems, no issues. It was clean and easy. So the people that we used to install the solar panels were very courteous, very attentive, very knowledgeable. They came to the house and explained things to us. They even came when I asked them to come and it wasn't scheduled for them to visit, and they would explain and answer questions for me, point things out, and I felt like I was in very good hands, very knowledgeable, and they were very honest and transparent up front. If there was gonna be an issue, they would call me up ahead of time and let me know that there were a delay, or if something were to happen. So I felt very comfortable in this process, like I was in good hands. Purchasing solar panels for our home and our family was completely worth it for two reasons. One, financially. We don't really have an electric bill anymore. The panels have done so well that I'm net zero, and actually negative. The electric company owes me money at this point. My last bill was negative $17, and that's a great place to be. Also I'm a great steward of our planet, making sure I'm keeping my carbon footprint and my family's carbon footprint as small as possible. So we're very happy and very impressed with the product and our decision.

    I got the app of SunPower on my phone and I'm watching my progress. I'm doing really well and I'm really happy with it. It's working great for me. I was confused because there are so many people in my neighborhood where I lived before, they've gotten solar power and they're not getting any money back from it. They're paying for it on a daily basis. So I'm fortunate right now. I'm not paying any bills. I got a rebate on the first bill. It's great.

    So far, my experience with SunPower has been good. It took me a while to figure out how the graph worked. I eventually figured it out and I check it every morning even before the sun comes up, and it's all looking good. It looks like it's making more power than I'm using. I like that. I just wish SunPower would give me the option to install more panels. I have 17 but there's space for 18. I understand they're only trying to make 100% of what I used, but there's nothing wrong with making 200%. They left one little place out of there. It looks like it'd be a perfect place for one more panel.

    As far as the customer service from SunPower, it couldn't be any better. Every time I've called them or emailed, I've gotten a straight answer. They did the installation in one day, which was wonderful. And everybody on the crew seemed to know exactly what they were doing. I would ask them electrical type questions, being I was an electrical technician in the Air Force, and I was surprised that they seemed to know what they were doing. It just took forever to get Xcel out here to do their part and get it hooked into the existing wiring system. So, SunPower needs to get some connection with those guys to get that part go faster.

      The signup process went slow but partly because we live in Laguna Woods and a lot of times, permits are slow. Everything was done well with the installation. It went smoothly. The installers delivered the product and put it up in a quick manner. I was pleased with SunPower and we would recommend it. It's doing what it's supposed to do.

      So far, SunPower is good. In-between there was a little bit of a duration when the app wouldn't show the amount of solar production, but besides that, it's going well. Installation was very good. The only issue I had was that the person who was taking care of the thing didn't tell me the choices in terms of all the different panels I could have. So, there are certain other panels which are a little more costly, but they have much longer life and, production-wise, they're better. I was hoping I could get those, but he did not tell me and I got to know about that later. When I called him, he said, "Swadesh, even if I told you, we didn't have that available." That was why he didn't offer that. I also asked him, in case the production of solar goes down, what would be my option then. He said, "Then I will take a look at it in case it goes down. Then we'll figure out a way for changing the panels that's required."

      I had SunPower for 4 years. This company has gone out of business with no plans to service their equipment and left customer with a broken system and no one to service. I don't know how anyone could allow this to happen and no one stepped in to say how do we look out for our paying customer. This is the worst I have seen.

      I Have made dozens of calls since 2021, (when we purchased our home) to have our system repaired as it has never worked. It was never repaired and has not produced any solar power or savings for us. We were led down the garden path with many promises of our bill being reimbursed, pausing our payments until it was repaired, but Sunpower simply continued to take our money month after month for a defective product. There are several class action lawsuits against them, all for the same stuff

      Since the bankruptcy, their service is the worst. No response to calls (if they go through). Lately all I get is a busy signal. I tried emailing them to the email address they provided on their website. The email would not go through and after 4 attempts my email software said it was undeliverable. Now they are pushing new products. I would NEVER consider buying anything from them.

      The device that allows my system to communicate to the Sunpower website has been broken for 4 years and they provide no assistance. My last SCE bill show I made 2 kwh in a whole month. Apparently something is wrong and I can get no help. They say if you use another company to repair, it will void your warranty. (what warranty, they're bankrupt). They subcontracted to Renova who never responded to 5 calls I place with them for assistance since Renova is only interested in servicing the customers that they sold to and not legacy customers of Sunpower. If I were you, I would look elsewhere and not give Sunpower a second thought.

      I only selected a single star because zero stars was not an option. So I took over a prepaid solar lease through Sunpower when I bought my house. I had high hopes going in, but when I moved in I discovered my inverters were broken. I didn’t think too much of it 'cause I have a prepaid lease so Sunpower should fix them. I contacted them to get somebody to fix them, but I am still waiting for the fix (over 10 months). Had some hope because the contractor reached out and said they had the parts available, but when I contacted sunpower to pay for the installation they said submit a new online request for repairs, and now I’m waiting again. They have only one customer help line whose only answers are submit an online help request and I don’t know how long it will take, because I’m not a servicing person and there’s a lot of requests.

      I have three separate electronic requests pending, all of which have been pending over two weeks. They are also delaying the refinance on my house which is costing me hundreds of dollars. Their processes are so slow and inefficient you will wonder if there actually are people responding to these requests. I have had only heartaches and rage since signing up to be a Sunpower customer. The company resources pale in comparison to the number of customers they have, and I would legitimately feel sorry for any sucker looking to sign a new contract with the company. If I had a Time Machine I would never have gone into a lease with them. In all seriousness I would highly discourage any person from getting involved with Sunpower in anyway.
