【Automatic Operation】: In sunlight, the solar panel automatically powers the fan and reaches speeds of up to 3000 rpm. In low light conditions, the fan can work at a slower speed or stop completely. 【Efficient Cooling】: The solar panel with two fans effectively reduces the indoor temperature by releasing hot air and promoting ventilation. 【Easy to use】: Simply position the solar panel in a place with sufficient sunlight, install the fan and connect it for immediate use. This wireless, battery-free product is not only practical, but also environmentally friendly and safe. 【Durable Design】The solar panels are laminated with epoxy resin on the outside and IP65 waterproof for improved durability and resistance to harsh weather conditions. 【Wide Application】: Ideal for various environments such as kitchens, greenhouses, pet houses, chicken coops, tree houses, caravans and more, to ensure a consistently comfortable temperature level. › See more product details; Product description Feature: * Cooling The solar panel assembly with two fans effectively reduces the indoor temperature by releasing hot air and promoting ventilation. * Easy to Use Simply position the solar panel in a place with sufficient sunlight, install the fan and connect it for immediate use.
