Frequently Asked Questions

What makes SunPower cells different?

SunPower uses innovative Interdigitated Back Contact (IBC) cell technology that places all electrical contacts on the back of the cell, eliminating front-side grid lines that can block sunlight. This design achieves industry-leading efficiency of up to 22.8%.

Are SunPower panels worth the premium?

SunPower panels typically cost 15-25% more than standard panels but offer higher efficiency, longer warranties (40 years vs 12-25 years), and slower degradation rates. For homes with limited roof space or long-term ownership plans, the premium often pays off through higher energy production and reliability.

What is the SunPower warranty?

SunPower offers a comprehensive Complete Confidence warranty including 40-year product coverage, 40-year power warranty, and guaranteed performance at 92% of original output after 25 years. This is among the industry's longest and most comprehensive warranty packages.

Can I buy SunPower panels in the USA?

Yes, SunPower panels are available through authorized dealers and installers across the USA. Following SunPower's 2024 restructuring, the technology continues through Maxeon Solar Technologies and certified installation partners.
