Designed for Toughness The SunPower Maxeon® Solar Cell is the only cell built on a solid copper foundation. Flexible panels made with SunPower cells are resistant to power loss via cracking and corrosion, unlike conventional cells, which are much more likely to lose power when bent or subjected to a moist environment. SunPower flexible panels are the #1 choice for customers due of the combination of high power and cell ruggedness. The panel can be installed with adhesives and/or use of stainless steel grommets in the panel. The panels have standard quick-connect cables. 5 year limited power warranty of 80% of the minimum specified power rating. An easy-to-follow installation guide is provided with each panel.
