The Good

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

Purchase, Lease, and Loan Options Available

SunPower offers three different payment options for customers to choose from that help them save on their electric bill: solar leasing, purchasing with cash, and financing with a loan.

With the lease option, SunPower Capital owns the system and the customer effectively rents the system via monthly payments. The lease comes with a 25-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 supplement the benefits of solar power ownership. Loan terms for solar systems typically range from 5 to 25 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 learn exactly how much solar will cost you is to obtain a free quote from SunPower.

High Efficiency Panels

SunPower has been on the cutting edge of solar technology for more than 30 years. Consequently, the company excels when it comes to innovation and design of solar cell equipment, enabling customers to be confident that they will have the highest-quality solar products expertly installed on their homes.

In fact, the solar installer provides the highest-efficiency solar panels you can buy today. The solar panel manufacturer engineers elite solar modules that are up to 22.3 percent in solar panel efficiency, and carry a temperature coefficient of -0.29, meaning output will not be negatively effected because of excessive heat. Each SunPower panel is made of anti-reflective glass and coated with anti-reflective film for optimum durability and to ensure that they capture as much sunlight as possible. In short, SunPower cells provide the best value for your money.

Industry-Leading Solar Panel Energy Production

The SunPower 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 a smaller solar installation and fewer panels than other companies.

Every SunPower solar panel also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower solar energy system pays off significantly more in the long run.

In addition, SunPower panels maintain their energy production much better than conventional panels in partially shaded conditions, making them a better rooftop solar option for customers who live in a cloudy region or an often shady area.

Attractive Appearance

In addition to being highly efficient, SunPower panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer conventional solar panels — traditional blue photovoltaic panels with bright, visible frames and mounting hardware — SunPower's panels are all black, and their mounting system sleek and nearly invisible, allowing the SunPower solar installation to blend in better with the rooftop on most homes.

SunPower SunVault Battery Storage

SunPower recently introduced SunVault™ storage — a powerful and sleek residential storage solution that pairs with SunPower Equinox®, the company’s premier residential solar power system. Once widely available, SunPower panels that are installed with SunVault storage will allow customers to have ready access to electricity even in the event of a power outage.

Monitoring

Monitoring of system status and performance is extremely important for customers who want to see how much energy the panels on their roof are producing —currently, as well as historically — and ensure that everything is operating as it should.

SunPower provides a helpful, convenient app for customers to do just that. The app provides important system information such as power output, estimated savings, energy production over time, and the environmental impact of the energy generated by the system.  All of this system information is easily viewed on a smartphone. 

SunPower systems also include a consumption monitoring kit, which is installed if the homeowner’s site is compatible. With consumption monitoring, homeowners can view current and historical energy usage, and the SunPower app provides more in-depth information about their energy profile. 

Industry-Leading Warranties

SunPower offers multiple warranties to protect its customers' solar energy systems, including a 25-year Complete Confidence product warranty, which covers the equipment itself, and a 25-year workmanship warranty, which covers the labor and solar 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 energy production and output.

The Bad

  • No PPAs for Non-Commerical Buyers
  • 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; however, the company's solar lease option can provide immediate financial benefits (and at a flat rate) to customers.

Customer Service Complaints

Some users on our site have provided negative feedback with regard to SunPower's customer service. Common complaints include difficulty to reach a representative, delays in returning phone calls and inability to resolve issues.

The Bottom Line

SunPower offers a number of payment options, the most efficient solar panels in the industry, state-of-the-art monitoring for its customers, and a 25-year workmanship and product warranty. 

While the company does not offer PPAs to residential customers, its lease program is a cost-effective alternative to outright purchase. The company leverages its dealer network to perform most of its installations, which in some cases can make it confusing for customers to know who to contact if there is an issue; however, these dealers are SunPower-trained and -certified, so customers should experience consistently high-quality regardless of service area or SunPower dealer.

SunPower Frequently Asked Questions

Is my home a good candidate for SunPower solar power?

Knowing how much you pay for electricity is the first step in evaluating whether your house is a good candidate for solar. The general rule is that solar makes the most financial sense for someone with a monthly electricity bill of at least $75. A utility bill of $75 is the threshold at which residential solar customers will see solar savings. Another factor is your home’s roof. It’s a good idea to replace a roof that is near the end of its life before installing solar panels. Solar panels should be installed on roofs that are in good condition and will not need to be replaced in a 20 to 30 year span of time. To find out more, homeowners can contact a SunPower representative. 

How are SunPower’s solutions different from traditional solar energy providers?

The SunPower Equinox® system is the only complete home solar system that is designed and warranted by one company. With the highest efficiency panels on the market, SunPower® solar panels provide more energy with less space. And homeowners can have confidence with the unique design of SunPower solar cells. With a solid copper backing, SunPower cells are resistant to corrosion unlike conventional solar cells. This helps the solar panels to perform more efficiently for a longer span of time. It’s one of the reasons that SunPower offers its homeowners a 25-year industry-leading warranty (Monitoring system warranted for 10 years).

Does SunPower provide a solar + storage solution for homeowners?

Yes. SunPower offers the SunVault™ Storage solar battery, which is comprised of two boxes: the energy storage system and Hub+™. Additionally, all customers receive access to SunPower's mobile app to view their performance and manage system settings. SunPower provides a 10-year warranty for SunVault Storage as part of the Complete Confidence Warranty — the same warranty that covers your SunPower Equinox solar system. It is important to note that SunVault Storage is only available in select locations at this time.

What should I expect during a SunPower solar online appointment?

SunPower energy consultants are experts in evaluating, designing, and estimating solar systems. Homeowners can expect an in-depth consultation that lasts approximately 45-60 minutes. During the call, an energy consultant will spend time assessing your current needs as well as how your needs might change in the future. To do this, a series of topics are discussed — from utility bill history to overall energy saving goals. These important details factor into the design of a customized solar system and include opportunities for you to decide where panels will be placed on your roof. At the end of the consultation, the energy consultant will provide you with a quote based on your energy needs.

Are there federal incentives available when going solar?

The biggest solar tax incentive is a federal tax credit called the Federal Solar Investment Tax Credit  or ITC. It is available to qualified homeowners who purchase solar energy systems for residential properties.* The credit, which is applied to your income tax, is equal to a percentage of the cost of eligible equipment. Many state and local governments also provide incentives for homeowners with solar power. A visit to SunPower's website can identify those offers based on location. * Tax credits subject to change. SunPower does not warrant, guarantee or otherwise advise its customers about specific tax outcomes. Consult your tax advisor for advice on how the tax credit may apply to your circumstances.

This company stands behind all the products they install. We've had no trouble whatsoever with the solar panels. The installation was quick, efficient, and reasonably priced. They've got a great warranty that is far superior than any other solar panel companies I researched.

SunPower is a little more expensive than other companies, but they were the only solar company willing to come down to our house for a quote. Our system works marvelously and the installation process went great. They sent us emails and called us with details on how everything would happen and what permits they were working on. They were very courteous and professional and the system can work with my phone and computer. The panels look great and we absolutely love this company.

When my system had some issues, I contact customer service and they gave me very quick responses and took care of me. They cared about my needs and fixed everything. The installation went smoothly and the installers were amazing. They did everything as planned and went above and beyond. One thing I wish I had was access to the panel level statistics that tell me if a panel is underperforming or if something's gone wrong. I don't like having to rely on someone at the company to find something that is wrong because I'd rather report that myself.

I'm very happy with the panels we purchased a long time ago, and SunPower installed some more for us one day. They called me the day before installation and told us they'd be here in the morning. They came as promised and did it all in one day. Overall, it was a clean and efficient installation process. The panels look really good and I'm happy with the service we've been provided.

Freedom Solar instatlled the system, and I have had continuous 'problem' with electric provider (Coop) because they 'weren't informed' other than I would e connecting to them with panels. If this is going to be seamless, someone needs to get the bumps out of the road. The system seems to work fine, but other issues have given me HEARTACHE..

It is hard to distinguish between SunPower and Cobalt who installed the system but my Sunpower app says my solar is not working, which I don't think is correct. I think there needs to be more done at the completion of a project to make sure the owner and investor understands the system, how it works, what settings they need to change with PGE and what all of the monitoring information means.

The panels that I got are absolutely fantastic. I'm producing more power than I consumer right now and it will help so much having these credits for when the summer really starts to crank up. The installers that came out were professional and courteous. The sales team was knowledgeable and professional as well. Every concern that I have had so far has been addressed quickly, except for one. The app doesn't work properly. I have emailed about it and thus far only been given lip service as to it being fixed.

I don't like that the billing is usually a surprise. They send a bill every three months and they aren't great at updating the billing website so I can see what I'll be billed. They are very nice to answer questions over the phone. It took a very long time for them to install everything - about 6 months from the day I decided I wanted solar panels installed. I like the way the panels look. They are very clean and great looking on my roof.
