ecoCalm 10-Inch Solar Exhaust Fan with Battery & Adjustable Thermostat – 2x15W Bifacial Panels

Sun-powered ventilation with smart flexibility

Meet ecoCalm’s 10-inch Solar Exhaust Fan, a compact solution designed to move air where you need it most. It teams a built-in 5000mAh rechargeable battery with intelligent power management, providing roughly six hours of airflow after a full charge in bright sun. The system automatically switches between solar power and battery energy as lighting conditions shift, helping keep spaces ventilated with minimal manual tweaks.

Smart control for steady comfort

The battery box includes an intelligent temperature control that lets you set a preferred ambient threshold. When the air nears that temperature, the fan can start or stop automatically, reducing heat buildup and helping you maintain a comfortable environment without constant adjustments.

Power from the sun, boosted by bifacial panels

Two 15W bifacial solar panels capture light from both sides, delivering up to 22W under favorable sun. This design can enhance charging and fan operation, offering more energy during peak hours. Real-world performance will vary with sun exposure and weather.

• Two panels can increase energy capture by up to 130% in ideal conditions compared with single-sided designs.
• Battery charging and airflow adapt to outdoor light, supporting night-time or cloudy-day ventilation.

Strong airflow for a range of spaces

Engineered blades and a robust motor push air up to 660 CFM, making it suitable for spaces up to about 1100 ft³—think greenhouses, attics, sheds, barns, and garages.

Outdoor-ready versatility

The IP44-rated housing guards the blades while you install the unit in a window or on a wall. A 14.8 ft cable provides flexible placement, and the design supports use as an attic vent, greenhouse vent, barn, garden shed, garage, or animal housing vent.

• Mount in a window or wall for direct outside air exchange.
• IP44-rated blades withstand outdoor exposure while running during daylight hours.

Notes: performance depends on sunlight; clearer skies yield stronger airflow and faster battery recharge. This description highlights possible benefits and use cases without guaranteeing results, offering a practical, off-grid ventilation option that adapts to your space.
