The Good

  • Purchase, Lease, and Loan Options Available
  • High Efficiency Panels
  • Industry-Leading Solar Panel Energy Production
  • Attractive Appearance
  • Compatible With Battery Storage
  • Online Monitoring
  • Lengthy Warranties

Purchase, Lease, and Loan Options Available

SunPower offers three different payment options for customers to choose from: solar leasing, purchasing with cash, and financing with a loan.

With the lease option, SunPower Capital owns the system and the customer rents the system from the company, requiring monthly payments. The lease comes with a 20-year performance guarantee, as well as easy options in case the customer needs to transfer the lease.

SunPower also offers outright purchase and financing options for customers interested in the tax credits and other incentives that come along with solar power ownership. Loan terms for solar systems typically range from 5 to 20 years and do not have any prepayment penalties attached.

The cost of a SunPower solar system ultimately depends on several factors, including current energy usage, available amount of unshaded roof space, the local utility’s net metering policy, and other factors. The easiest way to figure out exactly how much solar will cost you is to obtain a free quote from SunPower.

High Efficiency Panels

SunPower is on the cutting edge of solar technology and excels when it comes to innovation, design, and production of solar equipment, so customers can be confident that they will have high quality products on their homes.

In fact, SunPower makes the highest efficiency solar panels you can buy for your roof in today's market, and the company's solar cells are made of anti-reflective glass and coated with anti-reflective coating to ensure that they capture as much sunlight as possible. 

Industry-Leading Solar Panel Energy Production

SunPower's X-Series solar panels excel in terms of power generation and deliver 44 percent more energy per watt than competitive products. This means that SunPower can provide more clean power for its customers' homes with fewer solar panels.

SunPower panels also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower system will ultimately pay off more in the long run.

Additonally, SunPower panels maintain their energy production much better than conventional panels in partly-shaded conditions, making them a better rooftop solar option for customers who live in a cloudy region or a relatively shaded area.

Attractive Appearance

In addition to being highly efficient, SunPower's panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer traditional blue photovoltaic panels, SunPower's panels are all black, which helps them to blend in better with the rooftop on many houses.

Compatible With Battery Storage

SunPower's panels are compatible with the Freedom CPAP Battery produced by Battery Power Solutions. When a SunPower module is installed along with this battery, customers will still have access to electricity in the event of a power outage.

Online Monitoring

Online monitoring is extremely important for customers who want to see what the panels on their roof are producing and ensure that everything is up to par.

SunPower offers a helpful, convenient app for customers to do just that. The app provides important system information such as power output, savings, energy usage over time, and environmental effects.

There is also a consumption monitoring kit that provides more information than the app for customers who would like a more in-depth way to monitor their system. The consumption monitoring kit is installed by the dealer, but may not be compatible with all homes.

Lengthy Warranties

SunPower offers multiple warranties to protect its customers' solar energy systems, including a 25-year product warranty, which covers the equipment itself, and a 25-year workmanship warranty, which covers the labor and installation. The clean energy company also offers a 25-year performance warranty, which covers the customer in the event that their solar modules underperform in terms of electricity production and output.

The Bad

  • No PPAs for Non-Commerical Buyers
  • Few In-House Installations
  • Customer Service Complaints

No PPAs for Non-Commercial Buyers

Many customers may be interested in obtaining a SunPower module through a Power Purchase Agreement (PPA) because this payment method typically includes some kind of $0 down option, which eliminates a barrier to entry for them to go solar.

Unfortunately, SunPower only offers PPAs to commercial customers, so consumers who are interested in a PPA for their home solar system will not have much luck with this company.

Few In-House Installations

SunPower is performing installations itself in select areas of California; however, SunPower panels are available in 41 states, excluding the following, through a network of dealers:

  • Alaska
  • Montana
  • North Dakota
  • South Dakota
  • Nebraska
  • Iowa
  • Arkansas
  • Mississippi
  • Alabama

The dealer you choose will end up being your installer and customer care center for the life of the solar PV panels, which creates a bit of confusion as to who should be contacted (the dealer or SunPower) in the event that any issues occur.

Customer Service Complaints

Many users on our site have provided negative feedback in regards to SunPower's customer service.

Common complaints include difficulty to reach a representative, company failure to return phone calls, slow response time, and inability to resolve issues.

The Bottom Line

SunPower offers a number of payment options, some of the most efficient solar panels in the industry, online monitoring for its customers, and a lengthy workmanship and product warranty.

However, the company does not offer PPAs to residential customers and outsources most of its installations, making it confusing for customers to know who to contact if there is an issue.

We wanted to go solar to save on our electric bills and do something good for the environment. We chose SunPower and couldn’t be happier. SunPower’s technology is the best in the market and they have the most efficient panels of anyone else. Our system was turned on yesterday and it’s already producing beyond our expectations! The entire experience from the energy consultant to the project coordinator and the entire installation team was awesome. We’re very excited and satisfied and would recommend SunPower to anyone looking for the best solar solution.

We started our relationship with Sun Power almost 1 year ago. Many promises where made and not fulfilled. How long it would it take to get installed,money we would save, bills from electric company customer service, etc. we have been told by the installers it isn’t working told faulty parts asked for a supervisor to call never happened. Today I will make another call and ask them to remove it. We are seniors , my husband is 100 % disability we can’t deal with all this stress. We will take whatever steps we need to end our relationship with Sun Power. I see a lot of others have similar problems this pass year. Something changed!

My experience with SunPower has gone from “good” during installation to “terrible” following the installation. I have had ongoing issues with my system not functioning properly since it has been installed and now I believe SunPower is over inflating the monthly energy consumption that they report for both the grid and solar power when compared to the energy consumption reported by my electrical supplier. NO one at SunPower can is able to address this issue when Incall customer service and NO higher level manager ever calls me back. I am extremely frustrated and plan to report this to the Better Business Burueau and any other consumer watch dog group that can assist me in getting SunPower to respond to my requests to discuss these irregularities with me.

They installed the panels incorrectly and it lead to some flooding in our attic. Our plumber showed what happened but they denied everything. Part of our contract calls for them to wash the panels at least once a year. They've never done it since installation.

Our positive experience began with the sales rep, Franz S. It continued with our project manager, Becky S. We were kept updated during the entire process and things went on schedule. Our panels are attractive (hardly even noticed) on our 1750 house. One of the greatest advantages to SunPower has been the quick response to any correspondence we have exchanged with all parties. They take responsibility for their system and are always available for help/questions/answers. Our experience has felt like a "partnership" with this company. They didn't install, say good luck and go on their way. They have been there when we needed them. Love the app that tracks the power, etc. Anxious to see results when warm weather is in full swing!

SunPower has the worst customer service you can imagine. If you have a problem, good luck. My system has been broken and underperforming for 9 months and they will not communicate. If I want to know anything I have to call and wait on their automated phone service. No emails, no phone calls. I have been calling every couple of weeks for 9 months and explaining the poor service I am getting. They have told me at least 3 times my case has been "escalated." It has been 9 months and my system still isn't fixed, but I had to pay a huge true-up bill for last year because of its underperformance. I am in a new year now and because it isn't fixed they are ruining this years production as well. They assure me they will fulfill their contracted guaranteed power delivery, but because my system makes significantly more than that I lost that production last year and I will lose it again this year. I also live in California and SunPower will only pay for the lowest tier price at .12 per kilowatt hour. I am having to pay the highest tier price because of my system's lack of performance. A customer service guy finally emailed me saying he would like to talk to me more about the poor customer service. I have called him several times and emailed 3 times and he has yet to return my calls or emails. That was a month ago. They do not do what they say they are going to do. There are plenty of other companies to go with. SunPower is not worth your time.

I had solar installed by Sunpower,the work force was totally committed to their job and had the work completed in one day. The finished project was cleared by Sunpower and the town inspector. I am completely satisfied with the work at hand and now enjoying the sun for my energy. I would recommend this Co. To all my friends and neighbors. In support and feedback alone this is an A1 company to deal with,everyone involved was very considerate and truthful in every regard. Everything was laid out exactly the way it was going to happen and it did with no hitches.

I talked to a Mr. Desmond W. about how solar works and how beneficial it would be for me to invest in solar for my home. Desmond answered all of my questions honestly and I really appreciated that. At this point my wife and I are really considering solar.
