How do automatic greenhouse window openers operate without an electrical power connection?

Automatic window openers utilize a mineral-wax-filled cylinder that expands as ambient temperatures rise, pushing a piston to mechanically raise the vent window, and contracts as temperatures cool to close it automatically.

How do I size an exhaust fan for an outdoor greenhouse structure?

Calculate total internal volume in cubic feet (length × width × average height) and select a ventilation fan with a CFM rating equal to or greater than the total volume to achieve one full air exchange per minute in hot conditions.

Why choose this product

Sustainable Ventilation Powered by Sunlight

This pqins solar greenhouse fan harnesses the sun's energy for efficient air circulation, reducing your carbon footprint and electricity bills. Unlike local fans that require constant power, this unit operates autonomously during daylight. Its robust, waterproof design ensures longevity even in India's varied climates, from humid coastal regions to dusty inland areas. The separate solar panel and fan offer versatile installation options, making it a practical choice for maintaining optimal conditions in your greenhouse, chicken coop, or shed without ongoing energy costs.

Ideal for Greenhouses & Coops, Skip if Grid Power is Essential

This fan is perfect for small to medium greenhouses (up to 120 sq.ft.), chicken coops, sheds, or attics where consistent, solar-driven ventilation is desired. It's an excellent choice for those seeking eco-friendly solutions or operating in off-grid locations. However, if you require ventilation that operates reliably at night, during heavily overcast days, or needs precise temperature control independent of sunlight, consider a mains-powered fan with a thermostat. This solar unit's airflow is directly tied to solar intensity, so consistent performance in all conditions is not guaranteed.

How to use

Position the solar panel in a location that receives direct, unobstructed sunlight for most of the day. Use the included bracket, screws, or iron plates to fix it securely to a wall, roof, or pole. — Mount the Solar Panel
Attach the fan unit to your greenhouse wall, shed, or desired location using the provided mounting iron plates and screws. Ensure it is securely fastened and positioned for optimal airflow direction (exhaust or intake). — Install the Fan Unit
Connect the fan to the solar panel using the 16.5 ft cord. Use the on/off switch on the cord to manually control the fan. The fan will operate when sufficient sunlight is available. — Connect and Operate
