Solar Powered Exhaust Fan Kit, 25W Panel, 4 Fans

Solar powered exhaust fan setup improves airflow in greenhouses and coops without wiring, helping reduce heat, humidity, and stale air fast. A 25W solar panel directly powers four high-speed DC fans, with speed that responds to sunlight intensity. The adjustable panel angle helps you align to seasonal sun for steadier daytime ventilation in grow tents, shelters, and other enclosed or semi-enclosed spaces.

• Delivers up to 440 CFM total airflow (4 fans) to speed air exchange in tight spaces


• Runs on sunlight with a DC direct connector—no grid power, no voltage conversion, no wiring


• Adjusts panel angle for better sun alignment; operates daytime only (no built-in battery)


• Protects with double-layer metal guards and IP65-rated fan housing to resist debris and humidity


• Includes mounting hardware for roof, wall, ground, or vent installs across multiple locations

Built for hot, humid environments, this ventilation set pairs an aluminum alloy fan housing with a tempered glass solar panel for dependable outdoor use. In strong sunlight, the 2668 RPM fans help push out trapped heat and bring in fresher air—ideal for backyard greenhouses, grow tents, chicken coops, and shelters where consistent circulation matters. Keep in mind output varies with sun conditions; on cloudy or shaded days, the fans may slow or stop. Grab yours today and set up cleaner airflow in minutes.
