Waveshare 18V 10W Semi-flexible Polycrystalline Silicon Solar Panel 1. Using semi-flexible polysilicon solar panels, light and portable, easy to use outdoors 2. Integrate 5V voltage stabilizing circuit, and lead out 2 USB ports, which can be powered by external 5V devices through USB, with working indicator light 3. Reserve the DC5521 power interface, which can be used to connect to a power management module or controller that supports 18V solar panels 4. Comes with a variety of accessories and adapter cables for easy use Parameter: 1. Solar cells: polysilicon 2. Surface material: semi-flexible laminate (not overbending) 3. Solar panel power: 10W 4. Output interface: DC5521 female port - The solar panel is not converted, and the power supply interface is directly output - Working voltage: 18V +-5% - Working current: 600mA +- 5% (Max) - Open circuit voltage: 21.6V +- 5% Dual USB 5V ports: - After the solar panel passes through the 5V voltage regulator circuit, the output power supply interface - Working voltage: 5V (sufficient power and stable 5V output only if the sun is well illuminated; if there is no sunlight or the light is weak, the output voltage and power are insufficient, so it is not suitable for use) - Output current: 1.5A (voltage regulator circuit can support 5V3A output, but limited to -solar panel power, actual use of light and loss, 2-way total output up to 1.5A) 5. Product size: 435 200mm Note: The above parameters are tested under standard conditions (1000Wm2 radiation intensity, 25 degrees Celsius temperature, AM1.5 air quality)
