Feature: 1. Flexible Solar Panel: The flexible solar panel can power most of the 12V battery power and lithium battery and other devices, is energy saving and environmentally friendly, and is very suitable for outdoor work, travel or camping training. 2. Anti Backflow: The flexible solar panels have built in blocking diodes that prevent the battery from discharging at night without damaging the circuit boards in the battery due to backflow. 3. Monocrystalline: Compared with polycrystalline silicon, monocrystalline silicon photovoltaic modules have higher photoelectric conversion rate and better performance. 4. Excellent Compatibility: One flexible solar panel is suitable for 12V system, 2 solar panels can be used for series 24V system and parallel 12V system. 5. Waterproof: The solar panel is suitable for all kinds of weather, has a waterproof design, and can be installed in outdoor scenes such as RVs, tents, etc. Specification: Item Type: Flexible Solar Panel Kit Material: Monocrystalline silicon, PET Maximum Power: 2 x 70W Open Circuit Voltage (voc): 20V Maximum Power Voltage (vmpp): 16v Short Circuit Current (isc): 2 x 4.5A Maximum Power Current (impp): 2 x 4A Irradiance: =1000W/㎡ Temperature Coefficient Voltage: (0.065±0.015)%/℃ Temperature Coefficient Current: -(160±10)mA/℃ Temperature Coefficient Power: -(0.5±0.05)%/℃ System Voltage: 1000V Ambient Temperature: -40℃-85℃ (-40℉ to 185℉) Air Resistance: 50psf (2400 pascals) Snow Resistance: 113psf (5400 pascals) Hail Impact: 25mm (1in) at 23 m/s (52mph).
