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 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.
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 equipment, enabling customers to be confident that they will have the highest-quality solar products expertly installed on their homes.
In fact, SunPower provides the highest-efficiency solar panels you can buy today. The company's panels’ solar cells are 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.
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 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.
In addition to being highly efficient, SunPower panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer 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, blending in better with the rooftop on most homes.
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 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.
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 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.
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.
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.

Thoroughness, ease of working with. Staff goes extra mile to be sure all is correct. Promptly addressed minor issue.
The quality of the solar panels are great.
The installation was efficient, but there were a myriad of issues with procedures like: coordinating the inspection, coordinating rebates, and most importantly they affected the monitoring of a previous solar system. They finally heard me and sent a tech out to troubleshoot what happened. They now know how to correct it, but it has yet to be done. This issue is now 4 months old.
In Nov of 2019, I bought a new home from DR Horton builder. The homes come with Sunpower solar already installed. I bought the system upfront for $14k. As of today, March 23rd, the system is still not up and running. I have been calling to get it fixed but it takes weeks to get a technician to respond. I think they have only one tech for my entire region. It turns out that my power box in the garage was the issue. 4 weeks later it was shipped in, 2 weeks after that (On 3/12/20), finally someone came to installed. Even though it has power, it’s still not working. The tech told me that someone would reach out to me to communicate the power box to the “system”. No one has from Sunpower has called me. They have my $14k and I have nothing. I am making my rounds on social media and BBB and whomever else will listen. My realtor told me that Sunpower has landed contracts with many home builders so if you are going to buy a home, make sure you find out who the solar panels are from. Stay tuned. I will post a copy of my receipt for the purchase soon and any other updates I have. If they respond with excellent service, I will post that too along with dates on how long it takes them to fix their broken products. With the Coronavirus outbreak, I am going to assume they will use that as an excuse to buy them even more time although.. I have waited long enough.

thumbs way up
great, reliable product, recommend Sunpower
Good, Reliable and name brand Solar System
Performance of the panels are good and a received defective microinverter notification and replacement.
Very well built panels, terrible monitoring site. We have had these panels for two years. It is a 10kW that is delivering an average of 12mW/yr. We track our performance with a SolarLog which is needed to ensure that our SRECs are correct. The SunPower monitoring site worked poorly at first and now mostly not at all. Example, today we are currently running at 9.8kW. I know this from the SolarLog site. The SunPower realtime shows 0.2kW for production at the same time. We were told that we could track power productions vs power used, total fabrication until they hire someone to repair the site. We invested a lot to make this 1978 hummer of a house into a hybrid and a good monitoring system would go a long way to keeping it efficient. Too bad we didn't get that with the SumPower panels. Our installer, BluSel, is fantastic. They have tried everything possible to be sure the install didn't have any issues. This rests solely on SunPower and their neglect of this aspect of their business. I have 45 years of experience as a vender to the solar panel industry, these are good panels. Too bad after install support is non-existent from the factory
a Sub contractor installed my panels , Did a terrible job contacted SunPower They immediately sent a reprehensive out and corrected the problem and did a prefect job I would Highly recommend SunPower but not a Sub contractor
Delivered as promised on time after 1 year no Edison bills.
verry nice people and a 25 year gaurantee made it easy to deal with. I will use them again
Quality of the product, installation and customer service.
I have had the panels for a year and have no issues. I am producing more electricity than I use.
They were responsive to our needs and do high quality work.
corrected the installation issue fast and less equipment installed in my house.
There are too many times my app doesn't give me my info because the system is not functioning properly. If I delete the app and start over that usually gives me access again. Very awkward to do all the time.
Right now I'm being generous. My system is not still 100% functional
Sunpower has made good on all their promises, and they seem to be getting even stronger, while another company tried to 'steal' me away with underhanded practices and deceit.
Our panels are working well and the installation was relatively painless.
Best Solar Panels & Price, Their people make it effortless.
Solar production was great even on overcast days.
They have been very forthright. It did take quiet a long time to get it installed.
did a professional job in a timely manner
I like SunPower panels for efficiency, appearance and reliability.
Best efficiency. System is working without any problems.
