Sunpower Solar Panels

SunPower solar panels are built on a solid copper foundation, making them more robust than any other panel on the market. They’ve proven to be better across more than five cell generations, 3.5 billion cells and 30 million panels, even in the harshest of conditions. Conventional solar cells lose power over time because of corrosion and breakage. The unique design of SunPower solar panels eliminates 86% of the reasons that conventional cells fail. So your SunPower panels – and savings – continue to deliver. SunPower’s warranty is longer than any other manufacturer’s: 40-year performance warranty; 40-year product warranty.

Why The Energy Experts Recommend Sunpower Solar Panels

  • They produce more electricity in low light and in hot/humid conditions than any other panel.
  • SunPower is one of the most efficient panels you can buy, meaning less roof space is required to achieve a given system size, which is important if you may want to keep some space free for future system expansion.
  • SunPower is the only panel manufacturer that offers a 40-year product and 40-year performance guarantee.
  • One of the main reasons you’d want to go with SunPower is temperature cycling. As the temperature goes from cool to hot during the day it can cause fractures in cheaper solar cells. SunPower panels don’t fracture due to the built-in strain relief between the cells.
