1. Solar-Powered Efficiency: Utilizing dual fan solar panel technology, this solar fan expels hot air from indoors, significantly reducing room temperatures for a cooler environment. 2. Sun-Activated Operation: The solar powered fan kits automatically activate when connected to the solar panel and exposed to sunlight, achieving speeds of up to 3000 rpm for immediate relief. 3. Light-Dependent Performance: Designed to adjust its speed with the intensity of sunlight, the solar panel exhaust fan operates more slowly or may stop when solar energy is insufficient, ensuring energy is used efficiently. 4. Easy, Wire-Free Setup: With no wiring or batteries required, this solar cooling fan offers flexible placement and increased safety by harnessing solar power, featuring an epoxy resin laminated and IP65 waterproof rating for enhanced durability. 5. Versatile Application: The solar ventilation fan kit is perfect for a variety of settings, including homes, RVs, greenhouses, sheds, and pet houses, offering a broad range of use for any space.<br><br> Type: Monocrystalline Silicon Solar Panel Size: 335mm (13.19in) x 270mm (10.63in) x 2mm (0.08in) Fan Size: 120mm (4.72in) x 120mm (4.72in) x 25mm (0.98in) Solar Panel Line Length: 3 meters Fan Cable Length: 0.9m Maximum Power (pmax): 15W Open Circuit Voltage (voc): 14V Maximum Power Voltage (vmpp): 12V Short Circuit Current (): 1.22A Maximum Power Current (impp): 1.6A Output: Waterproof DC Interface x 2 (Picture version) Color: Black Material: plastic<br><br>Package Contents: 1 * Solar Panel Fan kit<br><br>Only the above package content, other products are not included.
