This solar ventilation fan comes with a bifacial solar panel and a 4400mAh rechargeable battery. The fan operates for 8 hours when the battery is fully charged by sunlight and seamlessly adjusts power modes based on sunlight availability. The battery box features an intelligent temperature control system, allowing the fan to automatically turn on and off based on personal settings. The 8W transparent solar panel generates power from both sides, reaching up to 20W, with an efficiency increase to 130%. Power generation supports both fan operation and battery charging, though efficiency varies with weather and decreases on cloudy days. The design includes advanced blade and motor engineering to maximise airflow. The airflow of the 150 mm fan reaches 137CFM, suitable for areas up to 29 m³, such as greenhouses, chicken coops, and sheds. This outdoor battery solar fan includes IP44 waterproof fan blades and a 450cm cable with a waterproof plug, making it suitable for use as an attic fan, and in barns, roofs, sheds, garages, animal houses, camping, and caravans.
