Description
Bulid-in 9000mAh rechargeable battery: The 20W solar panel is equipped with a large-capacity battery to store energy. It not only uses completely solar energy as energy to drive the fan but also transfers to electricity power to run it. Once turned on the fan, the battery will consume power during operation and supply power to the fan at the same time as the solar panel to ensure that the fan can continue to rotate. If you need to store power, please turn off the fan switch. Otherwise, energy cannot be stored.20W Efficient Panel & Strong Airflow Fan: 20W waterproof monocrystalline solar panel can reach up to 23.5% efficiency, providing enough energy to ensure the solar fans' normal working. It runs over 4 hours (Cloudy and rainy days) to 8 hours (Sunny days) depending on the wind speed level. Warning: Solar fan performance will be dramatically reduced if the angle of the solar panel is mismatched or the weather is cloudy, which may result in it running at a low rate or completely off..Two-Mode Wind Speed Level & ON/OFF Switch: There is the Mode button with a blue indicator light to indicate the solar fan is in charging condition and control two levels of wind speed: High-Speed level/ Low-Speed level. You also can press the ON/OFF switch to turn off the solar fan.The speed of the fan is greatly affected by sunlight. When the sunlight is weak, the fan will work slowly or even stop working. Warm tips: When storage power is no electricity in rainy and cloudy, you need to turn the fan off and charge the solar panel for 8 hours under the sun after using it again..Solar Dual Fan Kit for Intake or Exhaust Air: The solar-powered fan main frame and fan blade are made of premium ABS material, 4pcs metal protection net to prevent small animals from being injured and eliminate the risk of touching the blades. It easily pushes the heat, potentially harmful fumes, smells, moisture, and dust out, and circulates the air. It is a good solar air conditioner system for the home and outdoors. Suitable for small space ventilation, ideal solar fan for a small greenhouse, chicken coop, shed, pet house, or window exhaust..Important Notice: At First, we need to put the solar panel under the sun to charge for 6 hours before use. Secondly, please test whether the solar exhaust fan can work properly under the sun before installing it on the wall. Thirdly, the duration of sunlight and the temperature in the morning, middle, and evening, the angle of the panel, will affect the voltage and power of the solar panel..The Size of Solar fans：4.72" * 4.72" * 0.98", solar panel size: 7.48" * 9.44", line length: 17.7 ft, air volume: 350CFM, speed: 3500PRM/min, noise: 36dB max, DC: 12V/0.3A. The solar panel and fan can be plugged through the waterproof connector, and the solar panel has reserved mounting holes for you to fix it on any wall or roof, you can adjust the angle of the solar panel to make sure it absorbs full sunlight.
