Solar Exhaust Fan, 20W Panel, Battery, 220 CFM

Solar powered exhaust fan delivers steady ventilation to reduce heat, humidity, and stale air in greenhouses, grow tents, chicken coops, and shelters. A built-in battery stores energy for day-and-night airflow, while sunlight-responsive speed helps push out warm air faster in stronger sun. Designed for outdoor use with an IP65-rated solar panel and metal guards to help block debris, it’s a practical upgrade for spaces that need reliable air exchange without relying on mains power.

• Delivers up to 220 CFM airflow to speed air exchange in enclosed or semi-enclosed spaces


• Runs 24/7 with built-in battery storage for night use and cloudy-day ventilation


• Adjusts panel angle to better match sun position for more stable output


• Protects with double-layer metal guard to help keep out leaves and debris


• Installs easily with included brackets, screws, anchors, and cable ties for DIY mounting

Keep airflow moving where heat and moisture build up quickly. This DC 12V solar vent fan supports fast air exchange for small greenhouses, grow tents, chicken coops, and livestock shelters—helping reduce nighttime stuffiness and ammonia odors without complicated wiring. The tempered glass solar panel and aluminum alloy build are made for outdoor conditions, and the low 45 dB operating noise is less likely to disrupt animals. Set the panel angle, mount to a wall, roof, or vent opening, and grab yours today.
