Safe and Effective Ventilation: Harness the power of the sun for a cost-effective cooling solution. This kit enhances air circulation without adding to your electric bill. However, please note there's no battery included; thus, the system operates only in direct sunlight. Effortless Setup Process: Installation is a breeze with this system. Simply connect the solar panel to the fans using the provided interface and position the setup in a area for immediate activation and continuous operation throughout the day. Weatherproof and Reliable: Featuring a motor coated to prevent damage from short circuits or rain, this solar panel achieves an IP65 waterproof rating, making it ideal for outdoor setups. Note: Do not submerge the fan in water to prevent irreversible damage. Advanced Solar Panel System: This 12W solar kit includes a high-performance monocrystalline silicon solar panel (size:28x28cm) and two fans (size: 12x12cm each), efficiently removing hot air and odors from spaces like small chicken coops, greenhouses, and pet houses. Sunlight-Dependent Operation: The operational efficiency of the fans directly correlates with sunlight intensity. Performance peaks under strong sunlight, reducing during cloudy conditions and ceasing at night due to the absence of an internal battery., Weight: 1.18388234694 Pounds, Manufacturer: Tuidzljd
