• 【4 Fans + 20W Solar Panel】This solar fan set includes four 5-inch fans and a 20W high-efficiency solar panel. Compared to similar products with only 2-3 fans, it can quickly cover larger spaces like greenhouses, chicken coops, and sheds, eliminating hot spots. The 20W power far exceeds the lower-power 10W/15W models, providing more power and ensuring continuous and stable fan operation, easily resolving issues such as poor air circulation, odor accumulation, and high temperatures.
• 【Warm Tips】This solar fan does not have a built-in backup battery. Fan performance will decrease on cloudy days or when the panel is blocked.Please expose it to sufficient sunlight. And it will stop working on rainy days or at night. All four fans must be assembled before plugging in the solar panel power cable. Using the fan without a fully assembled fan may cause overvoltage and damage the product.
• 【Multi-Scene Compatibility】Designed specifically for outdoor use, this 4-fan solar fan set is perfectly suited for greenhouses (for temperature and humidity regulation), chicken coops (for ventilation and moisture control). The four fans can be flexibly configured with intake and exhaust modes (such as 2-in, 2-row, 3-in, 1-row, or full intake/full exhaust) to meet the air circulation needs of different spaces.
• 【11.5-foot long cord with switch】The solar fan comes with an 11.5-foot (approximately 3.5-meter) long power cord , allowing installation regardless of the solar panel's location. The solar panel can be mounted on a well-lit rooftop, and the fan can be fixed to a key ventilation point, such as the side wall of the chicken coop or the roof of the greenhouse, making the long cord easy to connect. Even a novice can complete installation in less than 10 minutes.
• 【Zero electricity bills for peace of mind】This solar fan set is powered entirely by solar energy, eliminating electricity bills. When all four fans operate synchronously, air circulation efficiency is significantly improved compared to a single fan, quickly dissipating greenhouse heat and chicken coop odors, maintaining a comfortable outdoor environment. With no risk of wire entanglement, it's safer for chickens and crops, ensuring a practical and cost-effective solution.‌
