Rossesay Solar Exhaust Fan Kit 2 Sets 25W 12V for Chicken Coop — IP65 Waterproof, USB Backup

Rossesay's 2-set solar exhaust fan kit is a 25W, 12V dual-fan ventilation system powered by a weatherproof monocrystalline solar panel and USB backup for reliable, battery-free airflow in small outdoor buildings.

If you need affordable, low-maintenance ventilation for chicken coops, greenhouses, dog houses, sheds or RVs, this Rossesay kit supplies continuous airflow whenever sunlight is available and offers a USB option for after-dark use. The system combines a compact 25W solar panel with two metal-mesh protected fans sized for modest enclosures. Its IP65-rated components and lightweight design make it easy to mount outdoors and resist the elements while keeping air moving to lower heat, humidity and odors.

How will this kit improve airflow in a chicken coop or small greenhouse?

The dual-fan arrangement accelerates exchange between inside and outside air so heat and moisture don't build up. Fans are mounted to create effective exhaust and cross-ventilation, helping maintain more stable interior conditions during sunny hours.

• Dual fan group (12.1 x 6.3 in) increases circulation compared to single-fan setups
• 25W monocrystalline panel (14.2 x 13 in) converts sunlight with up to ~20% efficiency
• Metal protective mesh prevents debris and animals contacting blades
• USB port allows connection to external power banks for nighttime use

Is the Rossesay fan kit durable for outdoor use?

Yes — the kit uses weather-resistant materials and IP65-treated accessories designed to withstand rain and dust. The panel and fan housings are built for repeated outdoor exposure so you won’t need frequent replacements in normal conditions.

• IP65-rated treatment on connectors and accessories for water and dust protection
• Sturdy metal fan shells and mesh guards reduce risk of damage from impacts
• Corrosion-resistant panel frame for long outdoor life
• Comes with mounting hardware and long wiring for flexible installation

How is the system powered and what if sunlight is limited?

The fans run directly from the 25W solar panel and do not include an internal battery — a deliberate design to keep the unit simple and energy-frugal. When direct sun is insufficient, you can plug an external power bank into the USB socket to maintain operation after dusk or on cloudy days.

• No built-in battery: runs directly from solar energy during daylight
• USB interface supports external power banks for night or low-light use
• 12V output matches common small-fan requirements for easy setup
• Lightweight components simplify repositioning to maximize sun exposure

How easy is it to install and where can I mount it?

Installation is straightforward: the kit includes the necessary brackets, fasteners and long cables so you can position the panel and fans independently for the best sun and airflow. The compact size and pretreated wiring make it suitable for walls, vents or window cutouts on many small structures.

• Complete installation accessories included for quick setup
• Long wiring lets you place the solar panel in direct sun while fans sit on the structure
• Lightweight fans and panel reduce the need for heavy-duty supports
• Suitable for chicken coops, dog houses, sheds, greenhouses, RVs and basements

Who is this for: The Rossesay 2-set 25W 12V solar exhaust fan kit is aimed at homeowners, small-hobby farmers and hobby gardeners who want a cost-effective, low-maintenance way to ventilate compact outdoor buildings without running AC power. It fits people who prefer solar-first solutions but want the option to use portable USB power at night or during cloudy stretches. If you need weatherproof, straightforward ventilation for poultry shelters, small greenhouses, pet houses, sheds or similar spaces, this kit provides a practical, easily mounted option.
