Rossesay 25W 12V Solar Dual Exhaust Fan Kit — Green 2-Fan, IP65 Weatherproof, USB-Compatible

The Rossesay 25W 12V Solar Powered Dual Exhaust Fan Kit is a weatherproof, battery-free ventilation system that uses a 25W monocrystalline panel to drive two metal-guarded fans for reliable airflow in coops, greenhouses, and sheds.

This all-in-one kit combines a high-efficiency solar panel with a compact dual-fan unit to move stale, humid, or hot air outdoors without relying on mains power. The components are IP65-rated for outdoor exposure, include USB compatibility for optional night or low-light use, and arrive with installation hardware and long connection cables so you can set it up on walls, windows, or roof vents quickly.

How does this fan keep a chicken coop or small greenhouse comfortable?

The twin-fan design increases air exchange by pulling warm, moist air out while drawing fresher outside air in. Faster circulation reduces humidity buildup and odors, helping maintain a healthier microclimate for animals and plants without ongoing electricity costs.

• 25W monocrystalline panel with ~20% efficiency for steady daytime power
• Dual 12V fans arranged to boost intake and exhaust flow
• Metal protective mesh prevents debris and animal contact
• Improves temperature and humidity control passively

Will it work in bad weather or at night?

The kit’s components are designed to resist rain and dust (IP65), so the panel and fan housing withstand typical outdoor conditions. Because the system does not include an internal battery, it runs when the panel receives sufficient sunlight; however, the USB port allows connection to an external power bank for evening operation or during prolonged cloud cover.

• IP65-rated casing and sealed accessories for durability
• No built-in battery — operates directly from sunlight for safety
• USB input lets you use a portable power bank after dark
• Long wiring included for flexible panel placement

How easy is installation and ongoing maintenance?

Setup is straightforward: mount the solar panel where it gets sun and fix the fan unit in a vent or wall opening using the included hardware. Routine maintenance is minimal — occasionally clean the panel and check the metal guard and connections — and the robust metal shell reduces wear from outdoor use.

• Complete mounting accessories and long cables in the box
• Lightweight components for simple handling and positioning
• Metal fan housing and mesh minimize debris buildup
• Quick visual checks keep the system operating well year-round

What spaces is this kit best suited for?

The Rossesay kit was designed for small to medium enclosures where passive, solar-driven ventilation can make a noticeable difference. It works well in locations that need improved air exchange but lack convenient electrical wiring.

• Chicken coops, duck houses, and small animal shelters
• Compact greenhouses and seed-starting rooms
• Sheds, basements, RVs, window exhaust points, and pet rooms
• Any off-grid or low-power ventilation application

Who is this for: The Rossesay 25W solar exhaust fan set suits homesteaders, hobby farmers, greenhouse growers, and RV or shed owners who want safer, energy-free ventilation during daylight and the option to run from a USB power bank at night. If you need a robust, weather-resistant solution to move air without adding utility bills or complex wiring, this kit provides a compact, portable option that’s easy to install and maintain.
