Built-in 9000mAh Rechargeable Battery: The solar panel, rated at 20W, is equipped with a high-capacity battery to store energy. It not only uses solar energy to power the fan but also transfers the stored electricity to run it. Once the fan is turned on, the battery will consume power during operation and receive a simultaneous supply from the solar panel to ensure the fan's continuous rotation. To conserve energy, turn off the fan switch when not in use.

Efficient 20W Panel and Strong Airflow Fan: The 20W waterproof monocrystalline solar panel can reach up to 23.5% efficiency, providing sufficient energy to ensure the solar fan's normal operation. It can run for 4 to 8 hours, depending on the wind speed level and weather conditions (cloudy/rainy or sunny). However, the solar fan's performance will be significantly reduced if the solar panel's angle is misaligned or the weather is cloudy, potentially resulting in low or even no operation.

Two-Speed Wind Levels and On/Off Switch: The solar fan features a Mode button with a blue indicator light, allowing you to select between two wind speed levels: high or low. You can also use the On/Off switch to turn the fan off. The fan's speed is greatly affected by the available sunlight. When the sunlight is weak, the fan will operate slowly or even stop working. If the battery is depleted during cloudy or rainy weather, you should turn off the fan and charge the solar panel for 8 hours under direct sunlight before using it again.

Solar Dual Fan Kit for Intake or Exhaust Air: The solar-powered fan's main frame and blades are made of premium ABS material, with 4 metal protection nets to prevent small animals from being injured and eliminate the risk of touching the blades. It efficiently expels heat, potentially harmful fumes, odors, moisture, and dust, while circulating the air. This solar air conditioning system is suitable for small-space ventilation, ideal for use in a greenhouse, chicken coop, shed, pet house, or as a window exhaust.

Important Notices: Before using the solar fan, you must first charge the solar panel under direct sunlight for 6 hours. Secondly, test the solar exhaust fan's proper functioning under sunlight before installation. Thirdly, the duration and intensity of sunlight, as well as the panel's angle, will affect the solar panel's voltage and power output.

Product Specifications: The solar fan measures 4.72" x 4.72" x 0.98", and the solar panel is 7.48" x 9.44". The cable length is 17.7 ft. The air volume is 350CFM, the speed is 3500RPM/min, and the noise level is a maximum of 36dB. The solar panel and fan are connected through a waterproof connector, and the solar panel has mounting holes for wall or roof installation, allowing you to adjust the angle to maximize sun exposure.
