VEVOR Solar Powered Fan, 20W Solar Panel with Battery Storage, 220 CFM Airflow, Adjustable Panel Angle, 2030 RPM High-Speed, Fast Air Exchange for Greenhouse, Grow Tents, Chicken Coops, Shelters

20W Solar Panel with Battery Storage for 24-Hour Solar Exhaust Fan Operation

A 20W solar panel powers the VEVOR solar exhaust fan, which continuously charges an integrated battery. This configuration ensures your space maintains consistent ventilation throughout the day by keeping the fan running continuously, even after sunset or in cloudy conditions. You never have to worry about a lack of sunlight disrupting your airflow cycle or running external wiring.

This fan's integrated battery makes it especially helpful in places where access to sunlight is limited. In chicken coops and livestock shelters, the stored energy powers the fan when needed to remove stale air, reduce stuffiness, and avoid ammonia buildup. Because stagnant air causes humidity and odor issues that daytime ventilation alone cannot resolve, both plants and animals benefit from this steady air circulation. You can maintain reliable air exchange without relying on the grid or manual switching thanks to this 24-hour operating cycle.

220 CFM High-Speed Airflow for Fast Air Exchange in Enclosed Spaces

When exposed to intense sunlight, this solar exhaust fan can push warm, humid air out of enclosed or semi-enclosed spaces at up to 220 CFM. The high-volume output reduces heat stress on plants and animals during the hottest parts of the day and helps greenhouses, grow tents, and shelters maintain a better indoor climate.

Stronger sunlight causes fans to rotate faster, providing more airflow; fan speed naturally increases with sunlight intensity. Because of its self-regulating function, the fan operates at its max during the hottest part of the day. As the temperature inside your building rises, more sunshine encourages the fan to run at its fastest speed, expelling as much air as possible before heat buildup harms your plants or animals. Faster air turnover during crucial hours is the outcome, and you will not need to make any manual adjustments.

2030 RPM DC Motor for Consistent Solar Exhaust Fan Performance

The fan produces a maximum air speed of 4.3 m/s when the DC motor runs at up to 2030 RPM. The solar exhaust fan's high rotation rate ensures it continues to deliver robust, consistent airflow even when the interior temperature rises dramatically. The DC motor design maintains high performance throughout the operating day while consuming less energy thanks to the 12V DC system.

The motor runs quietly enough at 45 dB to prevent upsetting animals in livestock enclosures or chicken coops. It is a sensible option in settings where sound sensitivity is important, thanks to its low noise level, especially when small livestock or poultry are under stress. You can efficiently ventilate your space without causing needless disturbance to the animals residing there, thanks to the high RPM, quiet operation, and low power consumption.

Adjustable Panel Angle for Flexible Sunlight Capture and Stable Output

Wherever you place it, the solar panel on this fan features an adjustable-angle design that lets you tilt it toward the sun for maximum energy capture. Regardless of whether the fan is mounted on a vertical wall or a south-facing roof, you can move the panel separately to match the available sunlight and keep the 12V DC output steady throughout the day without moving the entire device.

When seasonal solar angles change from summer to winter, this adaptability also benefits. To account for the lower sun angle, you simply adjust the panel angle rather than move the entire fan assembly. The battery charges more fully, the motor operates at higher sustained speeds, and the airflow in your space is stronger and more reliable when solar capture is better. You have better control over performance across various installation settings and seasons because the adjustable design eliminates the angle limitations typical of fixed-panel solar fans.

IP65-Rated Metal Guard Construction for Hot and Humid Environments

With its IP65 rating, the fan body is dust-tight and can withstand direct water jets from any direction. Because of this, it works well in greenhouses, chicken coops, and grow tents where humidity is consistently high and the environment is damp or prone to debris. While maintaining maximum free circulation through the blades, the double-layer metal guard across the fan face prevents leaves, debris, and small pests from entering the unit.

The solar panel uses tempered glass to provide long-term durability under direct sunlight. Tempered glass provides a longer service life for the complete unit because it is more resilient to impact, UV radiation, and thermal expansion than standard panel materials. This solar exhaust fan has the structural strength required to function reliably in challenging outdoor and semi-outdoor conditions year after year, thanks to its IP65-rated body and tempered glass panel.

Multi-Mount Installation Kit for Greenhouses, Grow Tents, and Chicken Coops

This fan comes with an installation kit, which includes cable ties, expansion anchors, brackets, and screws. Rooftop, wall surface, and direct-vent opening installations are the three primary mounting configurations supported by this hardware. You do not need to buy any additional hardware to choose the position that provides the best airflow path for your particular building.

This device is easy to handle and position during installation because of its compact panel dimensions of 13.78 x 13.78 x 0.63 inches and its total weight of 5.95 pounds. In most small structures, a single person can mount it without specialized tools or structural reinforcement. Hobby growers, small-scale farmers, and homeowners who want reliable ventilation without paying a contractor or running new electrical lines to a remote outbuilding can use the fan thanks to its simple setup.
