Product Rated power: 20WVoltage: 21.4VVop: 17.3VShort Circuit Current (Isc): 0.93AWorking current (Iop): 1.11AOutput Tolerance: 3%Size: 450*350mmMaterial: tempered glass + polycrystalline cell + EVAPackage content: 1 * 10W solar panel1.High EfficiencyHigh module conversion efficiency. Bypass diodes of the solar panel minimize power drop caused by shade and ensure excellent performance in low-light environments. Monocrystalline solar panels come with high-efficiency solar cells that help increase space efficiency.2.Easy InstallationPre-drilled holes on the back of the 20 watt solar panel allow for fast mounting and securing. Compatible with different mounting systems such as Z-brackets, Pole Mounts, and Tilt Mounts.3.DurableCorrosion-resistant aluminum frame for extended outdoor use(RV, Marine, Boat, Cabin), allowing the panels to last for decades. Anti-reflective, high transparency, low iron-tempered glass with enhanced stiffness and impact resistance. IP65 rated junction box provides complete protection against environmental particles and low pressure water jets.4.VersatilePerfect for small off-grid applications such as gate openers, fences, security cameras, lights. Float charge the battery of boats, RVs, SUVs, etc.
