SunPower services
When you purchase a solar system from SunPower, the partner will help you prepare documents for homeowners association review and obtain all the necessary permits.
After installing the system, the partner arranges for inspections and helps you obtain “permission to operate” orders from your utility.
Once your system is up and running, the SunPower Monitoring System (EnergyLink) gathers data to help you monitor and track your estimated bill savings. If you need help with anything, you can contact SunPower customer support Monday through Saturday.
SunPower solar panels and equipment
SunPower’s solar portfolio includes M-Series, X-Series and U-Series panels. Its Equinox line, manufactured by Maxeon, features highly efficient solar panels (compared with conventional solar panels). The same is true of its Helix line, which is available for commercial customers.
In 2020, SunPower announced a spinoff of its manufacturing department into a separate company named Maxeon Solar Technologies. This company manufactures the equipment SunPower designs and installs, so you’ll need to work with another solar company if you prefer a different brand.
SunVault storage system
SunPower’s SunVault storage system helps you keep your lights on even when the power is out. You 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 your system size and design, SunVault can help keep essential appliances running (like your refrigerator or HVAC) and power things like electric vehicles or washers and dryers during times without power.
SunPower solar panel installation
SunPower partners with dealers and installers nationwide to complete the design and installation process. These partners have all completed training and are SunPower-certified. The company incorporates a sleek, minimalistic rooftop design by using a low-profile mounting system called InvisiMount. This system uses durable metal wire clips to keep cables out of sight.

SunPower costs
SunPower found that a 5-kilowatt solar system typically costs between $11,150 and $46,100, which breaks down to $2.23 to $9.22 per watt. This price is before any tax credits or solar incentives. Since the costs can vary so much, the best way to get an accurate quote is to contact a SunPower dealer.
The cost of a SunPower solar system depends on several different factors, including your:
- Energy needs
- Local weather
- Roof layout
- Roof shading
- Size of your system
While SunPower may cost a little more than other solar energy companies, its high-efficiency solar panels and transferable warranty may make it worth it.
SunPower financing options
SunPower offers solar financing options with $0 down for eligible homeowners. With SunPower, you can purchase a residential system outright, pay with a loan or lease a system.
While leasing a system lets you take advantage of solar energy without a long-term commitment, you’ll need to purchase the system to take advantage of any tax credits and other solar incentives.

SunPower warranty
The SunPower Complete Confidence Warranty covers any repairs or replacements to the components on your roof for 25 years. This includes the microinverters, racking and solar panels.
All components not on your roof have a 10-year warranty. This includes your storage and monitoring systems. The warranty covers shipping and labor with no additional out-of-pocket costs. However, the smartphone and computer you use to monitor your solar panel production aren’t covered.
SunPower also guarantees your solar panels won’t lose more than 10% of their original power output in that 25-year period, which ensures your solar energy system stays efficient and produces the solar power your home needs.
The warranty does have some exclusions, including:
- Damage from natural forces, such as a tornado or earthquake
- Defects of the home’s existing electrical components at the installation site
- Damage caused by animals
- Damaged caused by third-party products
- Storage systems kept in temperatures outside the specified range
