VEVOR Solar Ventilation System — 25W Solar Panel with 4 High-Speed Fans, Up to 440 CFM, Adjustable Angle, IP65

VEVOR's solar powered ventilation system combines a 25W panel with four high-speed DC fans to provide daytime airflow without grid power.

Designed for small agricultural and hobby structures, this system converts sunlight directly into ventilation: the matched 25W solar panel powers the fans via a DC connector so you get steady, maintenance-light air exchange whenever the sun is shining. The unit requires no batteries or AC wiring, features a tempered glass panel and IP65 protection, and ships with mounting hardware for roof, wall, ground, or vent installation.

How much airflow can I expect from the 4 fans?

In strong sunlight the four fans together produce up to about 440 CFM, delivering fast air exchange for cramped or poorly ventilated spaces. Actual output varies with sun intensity and panel orientation; cloudy days and early morning/late afternoon sun will reduce speed.

• Peak combined airflow up to ~440 CFM in optimal sun
• 2668 RPM high-speed fans for rapid exchange when powered
• Fan speed proportional to sunlight — no battery smoothing
• Quiet operation around 45 dB to limit disturbance

Where and how can I mount the solar fan system?

The package includes brackets, screws, anchors, and cable ties so you can mount on a roof, wall, ground post, or into an existing vent. The solar panel angle is adjustable to track seasonal sun changes and improve daytime performance.

• Complete mounting kit for multiple surfaces included
• Adjustable panel angle for better solar capture
• Flexible cable length and DC plug for direct hookup
• Works in compact greenhouses, grow tents, coops, and shelters

Is this durable enough for humid or dusty environments?

The assembly is built for outdoor/agricultural use: an IP65-rated fan housing and double-layer metal guards protect moving parts from debris and moisture. The solar panel uses tempered glass for long service life, and the motor and guards are sized to resist common greenhouse conditions.

• IP65 protection against water spray and dust ingress
• Double-layer metal guard keeps out leaves and small debris
• Tempered glass solar panel for durability and weather resistance
• Low noise design (~45 dB) reduces stress for animals

What are the limitations I should plan for?

This system runs directly off sunlight and does not include an integrated battery or inverter, so it operates only during daylight and its performance depends on how much sun reaches the panel. In shaded or low-light conditions you should expect reduced or no airflow, and you may need supplemental ventilation at night or on overcast days.

• No built-in battery — daytime-only operation
• Output drops with cloud cover, shade, or low sun angles
• Panel positioning affects performance; seasonal adjustment recommended
• Not a replacement for continuous, climate-controlled HVAC systems

Who this is for: the VEVOR 25W solar powered fan system suits hobby growers, backyard greenhouse owners, small-scale farmers, and poultry keepers who need a low-maintenance daytime ventilation boost without running AC wiring. If you want a quiet, weather-resistant exhaust solution that uses only sunlight and installs with basic tools, this unit provides a plug-and-play way to improve airflow in compact enclosures.
