PQINS 7.1″ Large Solar Greenhouse Fan
The PQINS 7.1″ Large Solar Greenhouse Fan is designed for durable outdoor use with a 25W solar panel and a 16.5 ft cord. The fan reaches speeds up to 3800 RPM, delivering strong airflow for spaces around 80–120 sq.ft. Its solar panel operates separately from the fan, allowing you to place the panel outdoors while using the fan for exhaust or intake. Built with IP67 waterproofing and heavy-duty aluminum, it is engineered to withstand harsh environments and provide a long service life beyond seven years.
PQINS 7.1″ Solar Greenhouse Fan 2 Pack
This two-pack setup from PQINS features two 7.1″ fans, each with its own solar panel and a 16.5 ft cord. With a hi-velocity motor and blades delivering up to 3800 RPM and 900 CFM per unit, the pair covers ventilation needs for spaces roughly 150–230 sq.ft. The design supports flexible placement, enabling one fan for intake and the other for exhaust, or both as either intake or exhaust to optimize air circulation in greenhouses, chicken coops, or sheds.
SHENVITASO 25W Solar Exhaust Fan Kit
The SHENVITASO kit pairs a 25W solar panel with an 8″ fan to deliver up to 430 CFM at high speed (2300 RPM). It includes an anti-backflow valve and a 16.4 ft power cord, enabling flexible installation for sheds, coops, and greenhouses. The combination supports day and night operation, with the option to connect to household power via the included adaptor. The kit is designed for straightforward installation in small spaces with reliable airflow and minimal external wiring.
Pet Deluxe 25W Solar Fan With Battery
The 25W Pet Deluxe solar fan includes a built-in 2500mAh battery enabling overnight operation. It offers three smart modes: Continuous, Timed, and Sensing. The continuous mode keeps cooling on hot days, timed mode allows scheduled cycles for energy efficiency, and sensing mode detects poultry activity to automatically start and stop after a set period. The kit includes two independent fans (4.7″ and 9.84 ft cords) for flexible DIY installation as intake, exhaust, or a combination to accelerate air circulation in spaces around 6×6 ft or larger when multiple fans are grouped.
GROWNEER Solar Powered Exhaust Fan
The GROWNEER system combines a 30W solar panel with a robust 3200 mAh battery to deliver up to 1200 CFM and 1200 RPM. It is designed for large spaces up to 1400 square feet, including greenhouses and attics. The unit features a durable metal body with rust resistance and a built-in automatic louver that closes when the fan stops, reducing dust ingress. Noise ranges from 40 to 60 dBA, balancing strong performance with comfortable operation. This model emphasizes reliability and long-term outdoor use.
NHZOTUD Solar Powered Fan Kit
The NHZOTUD kit features IPX7 weatherproofing for outdoor durability, a 15W solar panel, and two fans designed for intake or exhaust. With a maximum rotational speed of 3200 RPM and up to 200 CFM airflow, it targets spaces up to 200 cubic feet. Its weatherproof design protects internal electronics, making it a practical solution for chicken coops, greenhouses, or dog houses exposed to the elements. The kit aims for an affordable, compact option with solid airflow performance.
Hhuiyu Solar Exhaust Fan Kit
This kit includes two mini fans powered by a 15W solar panel with IP67 waterproof design. Suitable for chicken coops, greenhouses, dog houses, and small spaces, it emphasizes portability and flexible installation, with separate fan units that can be mounted to optimize air exchange. The setup supports rapid deployment in various micro-environments where quick cooling is needed and solar efficiency is a priority.
Buying Guide: Key Purchase Considerations
- Space size and airflow requirements: Match CFM and RPM to the square footage of the area. Larger greenhouses or barns may need higher CFM and multiple fans, possibly in a paired configuration.
- Panel and battery configuration: Separate panels with the fan offer flexible placement, while integrated panels simplify setup. Battery backups improve operation during cloudy days or at night.
- Weather resistance and durability: Look for IP ratings (IPX7 or higher) and robust materials like aluminum or metal housings to withstand outdoor conditions and UV exposure.
- Noise and power efficiency: Consider decibel levels for quiet operation, especially in residential areas. Higher efficiency panels reduce operating costs over time.
- Installation flexibility: Independent fans and panels allow optimal placement for exhaust and intake, improving overall airflow and temperature control in variable climates.
- Backflow prevention: Anti-backflow valves help prevent pests or external air from re-entering when fans stop, especially important for coops and enclosed spaces.
- Maintenance and longevity: Long service life, corrosion resistance, and solid warranties contribute to lower total cost of ownership in outdoor environments.
- Power continuity: For night usage, consider models with built-in batteries or the option to connect to an external power source to maintain airflow during low sun.
Choosing the right solar powered fan involves balancing space, climate, and durability. The products listed here provide a range of configurations—from single high-capacity units to paired fans with flexible mounting—so you can tailor ventilation to your greenhouse, coop, shed, or dog house.
