Read full reviewWhat is SunPower?
SunPower is a solar energy company. It offers residential solar and storage solutions to help you receive the maximum benefit of renewable solar energy. The company upgrades your home or business with some of the highest wattage solar panels available from any solar company.
Solar panels arrive on-site with factory-integrated microinverters that optimize solar production and allow for faster installation. Local SunPower solar dealers understand the building and permitting codes in your area and provide customized services.
SunPower solar panels and equipment
SunPower's solar panels are durable and efficient. The panels use Maxeon cells, which have a unique solid copper foundation that adds strength and resists corrosion, outlasting conventional cells. SunPower offers four series of solar panels:
- M-Series: SunPower’s M-Series solar panels have a 22.8% efficiency rate, which makes it the most efficient M6 solar panel on the market as of the time of publication. Its Maxeon Gen 6 solar cells are 5% larger than prior generations. M-Series panels are the most powerful AC panels in the industry and are currently available up to 440W.
- X-Series: Built with anti-reflective glass that reduces glare, X-Series panels deliver up to 22.7% efficiency and are an excellent option when available roof space is limited.
- E-Series: The SunPower E-Series panels deliver up to 20% efficiency and are available in wattages of 320, 327 and 435. The E-Series is 36% more powerful per panel than conventional panels, according to SunPower.
SunPower mounting systems
SunPower designs its own mounting solutions, which are compatible with its panels and have an emphasis on superior looks and ease of installation.
InvisiMount, SunPower’s rail-based mounting system, comes with an all-black design and is adapted for most roof slopes and types. InvisiMount parts are 70% less visible than other comparable mounting systems.
Sunpower storage solutions
SunPower’s SunVault storage system is charged by your solar system during the day when the sun is out and can be discharged to provide power to your home when needed.
The SunVault Storage system is comprised of two enclosures, the SunVault Battery and Hub+. The system size starts at 13 kilowatt-hours (kWh), but homeowners that want additional backup power can opt for additional battery units (up to 52 kWh). The Hub+ features easy-to-use software to monitor solar production and home energy use, and itoptimizes battery charging and discharging for local utility rates.
Homeowners can set storage system preferences through the mySunPower app to decrease grid electricity use at peak times or serve as backup during a power outage. Depending on the system size and design, SunVault can help keep essential appliances running (like your refrigerator or HVAC) and power up things that provide more comfort in a household, including powering an electric vehicle charger or keeping a load of laundry running.
SunVault can deliver twice the amount of power when compared to conventional solar storage systems. This includes a multi-inverter configuration option so that homeowners can power more areas of their home during an outage.
SunVault Storage is included in SunPower’s Complete Confidence Warranty and is covered by a 10-year warranty.
SunPower cost
SunPower solar energy systems typically cost between $3.20 and $4.50 per watt. Altogether, a 6-kilowatt system from SunPower can cost up to $30,000 or more before incentives.
With SunPower, you can purchase a residential system outright, pay with a loan or lease a system. The company offers solar financing options with $0 down for eligible homeowners. Purchasing allows you to take advantage of tax credits and other incentives.

The panels that SunPower offered were good enough that I contacted them and came up with a system that would eliminate my electric bill, and it has since 2012. The techs who installed my panels were very professional and clean. I have a metal standing seam roof and they were very careful not to stand on the seams and not to puncture them when they used the clamps to hold the frame down to mount the panels on. They didn't fall off the roof either. For the first eight years or so, it was very easy to track my progress through the app but it was not that informative. Then there was a period when the app was changing, and therefore, I could not ever see any solar collected for that time period. Eventually, they finished the conversion nationally and regionally, and it's back to a new app that now provides more information.
The sales rep was really great, too. It's a shame that he isn't doing it anymore because I have reached out since then wanting to add batteries. And since my original sales rep isn't available, I get put to whoever is doing it now in our area. But I haven't been able to come to an agreement to add batteries because the last call I made was about my inverters . They are over 12 years old and they don't match with current battery technology which is dissatisfying. I also wish that there were more advertisements for cleaning services to clean the panel, because at my age of 78, I don't want to climb on the roof to hose them down and squeegee them.

"I had 23 years of previous utility bills that I added up and looked at the kilowatts used versus the increments of using more. I live in California where everything is upside down here. Natural gas was promoted in California 12 years ago. Now our governor is gonna get rid of that and he wants everybody to have solar panels. I was looking at it and mathematically, it's gonna be a return on investment down the road.
I researched a lot of companies and I realized there are only two American companies and everything else is fine China. SunPower came in at 24% in terms of efficiency. Their rep helped me along. The setup was the summer of last year and then it was six months later because they were booked up. We also had to wait for our electric company to come and disconnect the power from the post. Other than that, the job was done within a week once everything got okay.
December was when they installed the system. When the electric company came and did the final inspection, I didn't realize that the main panel switch for the electricity to turn on the solar panels was never on. A month later, I got a bill and I realized I was being charged normally. I called SunPower and they told me the system was not on. I thought they were gonna do that. They walked me through how to turn on the system.
That’s the only gripe that I had. SunPower dropped the ball on that. I'm an over-the-road truck driver. I'm gone two, three weeks at a time. I wasn't even home to even physically look at it to see where the switch says 'Off'. It's right next to the electrical panel outside. It's a small electrical panel and it's just a big switch, on-off. When everything is all said and done, go out there and take a look, because SunPower didn't tell me about that. So far, I've gotten my SunPower bill and it's going to be a doozy. They told me that I'm gonna have to pay it in two installments when they add it all up, which is horrible. If you're averaging $200 a month, times 12. And you're gonna have to pay it all in two shots."

I was considering solar for more than a year so I started doing my due diligence on the different companies. I wanted to know about the product, durability, and mortality. SunPower seemed to have everything I wanted such as the quality. It is made in the US, they've been around for a while, and they're publicly traded. I felt comfortable. I'm early into this solar thing and it looks like I have a zero electric bill. I'm actually putting power back to the grid. I'm in the black, even this time of the year in the Northeast.
I had an issue with the panels from day one. I had one panel that kept showing me it was offline on my app. I called my three-month representative and he kept telling me that it was data migration, this, and that. Everything looks good on the SunPower side. I wasn't buying what the representative said and I was insisting that they send somebody out. But he kept saying that was not necessary so I took it upon myself to call the 800 number for the first time. I was on the phone for more than three hours. Customer service told me there were times when the panel was not producing power, which really upset me because it wasn't what my representative was telling me.
It took another 10 days for SunPower to send a technician out. I said, "I paid for this. It's a $40,000 installation. It's not 100% working. Send him out with every possible part so this gets resolved." But the technician shows up with no parts. I wouldn't let him leave. He somehow he pulled out a microinverter from the back of his van and claimed it was brand new. He replaced that part. Lo and behold, the system's been working fine now for well over a month. On that whole, it was like pulling teeth just getting through customer service, convincing them to send somebody out because everybody wants to do everything remotely, checking the system, and sending an update. I was very frustrated. But I am happy now even though I have two minor issues going on.
I'm an engineer by trade so I understood the whole solar panel, power, and the apps. But I felt SunPower was dismissing that. It was almost like excuses, where they would check the system and say, "It was fine. We'll send a signal." They led me along for months and I really was upset about that. After giving my representative a 5-star rating, he just disappeared. I was really hoping he would be the guy to go and jump on somebody's desk and say, "Hey, we got to send somebody out there to fix this guy's solar system."
Anthony, we appreciate the review and we are so delighted to read your expectations have been met. Congratulations on going solar and thank you for helping us change the way our world is powered!
I had solar at a prior home and the home that I bought was a new construction with Shea Homes. I purchased a 5-kilowatt system with the home and it was a SunPower system. When I moved in, it was all hooked up and I found out based on some improvements that I had made, that the 5 kilowatts weren’t covering all my energy needs. So, I added another 4 kilowatts. And because I wanted to make sure that the system was compatible, I only worked with solar contractors that used the SunPower product. The sales rep was great, very knowledgeable and respectful of our time. His presentation made the decision easy and SunPower’s price was competitive. The financing that they offered through a local credit union helped us make the decision to move forward with the expense.
The installers, Mulholland Electric, were good. They came out, got on it and finished it quickly. There was one little hiccup though. And I'm not sure whether it was theirs or on SunPower’s end. I made it clear when I signed the contract that when I get the reporting data through the SunPower app, I didn't want to have to monitor a 5-kilowatt system and the new 4-kilowatt system. I wanted the data to be reported as if it was one 9-kilowatt system. They had to install a second inverter so there was a little bit of complication with trying to get the two systems to report as one. And it seemed as though that went back to SunPower corporate. It took a little bit more effort on my part to make that happen than I would have liked but it finally got worked out.
I'm not a big fan of the SunPower app. It's not very user-friendly in terms of graphing and the way that it graphically presents the information. I can figure it out but it's not as simple as it should be. I had a prior SunPower app with the first system, which was easier and better to interact with than the current one. But I'm also not somebody who sits there and logs into my app every day. I have friends that show their solar generating capabilities on their phones as if it's their grandkid’s pictures. Instead of working, just watching the kilowatts app. I don't do that. So, it's not a big issue.

When I called the SunPower and was interested to know where the cost would fall in the range compared to the other products that I evaluated, they came out competitive which was surprising. In fact, it was quite a bit cheaper than the previous bid I had gotten partly because the efficiencies are so high and the quality that the other product quoted would require more panels, which increased the cost.
The sales rep was fantastic. He talked to me about all the details that I needed to know. I really appreciated that he was honest and not salesy, like in a used car salesman kind of way, but more, "It's a great product. Let me tell you about it. Here's what you expect. Here's why it's a good product." For the price, it's a great product. They also worked with me through the rebates and the incentives they provided. They pointed me to the forms that I needed for the taxes. They really worked hard.
There were two things that we were working through. One of them was trying to get the installation done in the previous calendar year so I could apply for the rebates this year. Otherwise, if I had done the installation in January, I'd have to carry more of the debt to finance the cost of the install until the following year. They did the installation in a timely manner. They were able to pull it in and worked a little bit extra because it was right after the holidays. They tried to do mine and several others to try to get it in before the calendar year was over.
The other thing that we were working through was the cost. It didn't change. There wasn't any negotiation to coming down on cost. They were very honest that we tried to set things at a low cost. But it was the financing of it because it requires out-of-pocket expense. Very few people, myself included, have that sort of cash just lying around. But the sales rep was very good to help me understand what it meant if you were to finance through the solar power company or through someone else or if you were to put it on a credit card, to help me work through what would be the right option and the least costly for me and offering suggestions for me to consider rather than pushing me into a product, where I finance through them and they get the high profits off of the interests. I was able to come up with a financing solution that worked well for my family and didn't really cost much money at all to do the financing.
I've been able to read it through the app and I am net positive for the year as far as what's generated. The kids love to look at it. They try to monitor the power usage and it's been quite fun. I've only gotten one bill so far where the solar has been on it, and with the net metering, it's saving money. In case it goes up, I feel comfortable with how the power is coming through the panels and supplying it to my house.

The enrollment process with SunPower was transparent and seamless, and my interactions with the reps are awesome. They communicate and listen to the client. That's key to me. Installation was good as well. People were on time and they worked until the job at the end of the day, then they came back if they had to and finished the job. On the Nextdoor app, somebody is looking for somebody today and I recommended SunPower. For the last two months, my bills were negative.
What an excellent review! We are so happy to hear of your savings and satisfaction with our products. Thanks for helping us change how our world is powered!

The system restored by instruction of your customer service. Didn't realized that system down, rather just router problem. Because I use up the system credit and received monthly bill from local provider, ConEdison, was same. But this month bill came with full charge without any solar power, then I called your company to find out. The system was out since October 18, 2022, for 5 months. Your company's system should have automatic checking system to monitor 'No Generation' warning to customers. It's your system's negligence and 'VERY DISAPPOINTED'.
We apologize for your experience and appreciate the opportunity to restore your confidence in SunPower. Please expect an Executive Support Specialist to reach out to discuss these concerns in detail and provide additional assistance.
To continue to go green and save money. To have a advocate to analyze my generating power versus usage which I believe has been incorrectly billed by National Grid. I have been dealing since my billing of the first three months of 2022.
We sincerely appreciate the feedback and couldn't be happier with this glowing review! Please reach out to us in the future with any questions you may have. Thank you for helping us change the way our world is powered!
