20W 18V Solar Exhaust Fan, Solar Powered Vent Fan with Monocrystalline Panel, IP67 Photovoltaic Fan for Chicken Coop Dog House Shed Greenhouse

Item Type: Solar Exhaust FanSolar Panel: Material: Monocrystalline SiliconMaximum Power: 20W Open Circuit Voltage: 20V Maximum Power Voltage: 18v Short Circuit Current: 1.5A Maximum Power Current: 1.1A Output: DCWeight: Approx. 900g / 31.7ozPackage List：1 x Solar Panel1 x Exhaust Fan1 x Connecting CableNote:1. The fan is not equipped with a built in battery, and the solar panel can directly power the fan and work only during the day.2. The airflow is affected by sunlight, for example, on sunny days, the airflow speed is fast; On cloudy days or at dusk, the airflow speed is reduced.3. No power storage function.

• High Airflow Performance: This 20W 18V solar exhaust fan uses a monocrystalline silicon solar panel to deliver up to 3000 RPM under direct sunlight, creating strong airflow that quickly removes heat, odors, and stale air from enclosed spaces like sheds or greenhouses.
• All-Weather Durability: Built with an IP67 rating and protected by a heavy-duty aluminum frame plus metal mesh guard, this solar powered vent fan resists rain, dust, and impact, making it reliable for year-round outdoor or indoor use in harsh conditions.
• Versatile Application: Ideal for chicken coops, dog houses, small greenhouses, attics, camping tents, and storage sheds, this photovoltaic vent fan improves air quality wherever fresh ventilation is needed without requiring grid electricity.
• Premium Monocrystalline Panel: The solar panel is made of high-efficiency monocrystalline silicon, which generates more power than polycrystalline alternatives under the same sunlight, ensuring consistent fan operation during daylight hours for effective air circulation.
• Tool-Free Setup: Includes a flexible mounting bracket and nylon zip ties for quick installation on walls, roofs, or poles—just connect the fan to the solar panel with the included cable, position it in sunlight, and enjoy instant, silent ventilation.
