TARKARI Solar-Powered Chicken Coop Exhaust Fan — 25W Panel, Dual 120 CFM Fans, Auto-Sense Sensor

The TARKARI solar-powered exhaust fan is an off-grid ventilation system with a 25W panel, dual 120 CFM fans, a 2500mAh battery, and smart infrared sensing for automatic, energy-efficient airflow in coops, pet houses, and small shelters.

Keep small animal houses and outdoor enclosures fresh and cool without running electrical wiring. This compact system uses a higher-efficiency 25W solar panel to recharge a built-in 2500mAh battery, powers two 120 CFM fans, and offers three operating modes including an infrared Auto-Sense setting that starts ventilation only when animals are present. With IP65 weather protection, longer cabling for flexible installation, and a memory controller that saves your last settings, it’s designed for easy, low-maintenance ventilation anywhere sunlight is available.

How does the battery and solar panel keep the fan running through cloudy days or at night?

The unit combines a 25W high-efficiency panel with a 2500mAh internal battery to provide continuous performance beyond direct sunlight. The panel charges about 30% faster than typical 15–20W panels, and the battery supplies several hours of operation after dusk or during overcast weather.

• Fully charges in roughly 4 hours of strong sun.
• Supports about 5–8 hours of night operation depending on fan mode.
• Slow-charge capability reduces downtime on cloudy days.
• Recommendation: keep the controller sheltered in extreme cold to protect battery efficiency.

What does the infrared Auto-Sense mode do for my coop?

Auto-Sense uses a motion/heat infrared trigger so the fans run only when animals are present, minimizing energy use and noise. When the sensor spots movement, fans run for a 10-minute cycle and then stop; they restart automatically if activity continues.

• 10-minute automatic run per detection to reduce unnecessary runtime.
• Can be disabled for continuous ventilation when needed.
• Ideal for small enclosures (recommended for around 6×6 ft per unit).
• Multiple units can be installed for larger spaces or cross-ventilation.

Which fan modes are available and when should I use each?

The controller offers three practical modes: High/Low for straightforward cooling, Timer for scheduled on/off cycles, and Sensor for demand-driven operation. The memory function remembers your last mode and returns to it after power interruptions, so you won’t need to reprogram settings.

• High/Low — continuous strong or reduced airflow for hot or mild days.
• Timer — options like 1 hour on/1 hour off or 1 hour on/2 hours off for balanced ventilation.
• Auto-Sense — infrared-triggered cycles conserve battery and reduce runtime noise.
• Controller memory resumes previous setting after restart.

How durable and versatile is this fan for outdoor use?

Built from ABS and metal with an IP65 rating, the fan assembly is designed to resist rain and sun exposure while the protective guards keep animals safe from the blades. The included 3 m segmented cables between fan, controller, and panel give more placement flexibility than many competing kits.

• IP65 waterproof housing suitable for rainy conditions.
• Protective guards prevent contact with poultry or pets.
• Two 120 CFM fans can be mounted together or opposite for cross-flow ventilation.
• Versatile for coops, dog houses, greenhouses, sheds, RVs, and tents.

Who this is for: This TARKARI solar exhaust fan suits small-farm owners, backyard poultry keepers, and pet owners who need reliable, off-grid airflow without electrical work. It’s also a good match for anyone running small greenhouse vents, remote sheds, or camping setups where solar power and automatic sensing simplify ventilation and reduce energy costs. For larger barns or commercial operations, use multiple units or integrate into a broader ventilation plan.
