Founded in 1992, SunPower is a solar company that prides itself on delivering reliable energy and long-term peace of mind for homeowners and businesses. The company is a pioneer in the industry and currently holds more than 750 patents for solar technology.

SunPower is known for manufacturing top-quality and high-efficiency solar panels that generate more power than conventional solar technologies. The company has a uniquely attractive, all-black appearance for itself and offers a few different options to help both residential and commercial consumers get started with renewable energy. SunPower outsources most, if not all, of its projects to third-party solar installers.

Keep reading to discover The Good, The Bad, and The Bottom Line about SunPower, and check out SunPower reviews from real customers.

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 the following 18 states through a network of dealers:

  • Arizona
  • California
  • Colorado
  • Connecticut
  • Florida
  • Hawaii
  • Illinois
  • Maryland
  • Massachusetts
  • Nevada
  • New Jersey
  • New Mexico
  • New York
  • North Carolina
  • Oregon
  • Rhode Island
  • Texas
  • Utah

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.
