About This Refreshed Design: Generates power from both sides. The rear panel captures reflected light , boosting energy output. Higher reflectivity = more electricity. For optimal rear-side gains, install 28-50 inches (0.7-1.3m) above ground. Rugged Design: This solar panel’s dimensions are 36.61*22.83*1.18inch and its weight is 12.74Ibs. It can withstand high winds at 2400PA and snow loads of 5400PA. Maximum Power Capabilities: Its maximum power (Pmax) is 100W, with Voltage at Pmax (Vmp) at 17.1V, and the Current at Pmax (Imp) at 5.85A. Easy Installation: This solar panel comes pre-drilled for easy installation. Diodes are pre-installed within the junction box, alongside a pair of pre-attached 3ft solar connectors cables, making installing the panel a hassle-free experience. After-sales Service: With a 2-year material and parts workmanship assurance.10 years of power output is greater than 90%, 25 years of power output is greater than 80%.
