25W solar-powered 8-inch exhaust fan, 12V low-voltage plug-free operation, quiet and high-volume exhaust. Comes with a long-line solar panel with a switch, which can ventilate independently on sunny and cloudy days, preventing moisture and odor. Suitable for greenhouses, pet enclosures, storage attics, etc. Outdoor waterproof and sun-resistant, no wiring required, zero electricity cost for all-day fresh air circulation.

The complete set includes an 8-inch square silent exhaust fan, a 25W polycrystalline solar panel, an extension cable with an independent switch. All the accessories are provided, and it can be installed directly after opening the box. The size of the solar panel is 320*410mm. It can stably output 12V voltage under strong light, with sufficient peak current. The higher the light intensity, the higher the exhaust efficiency. On sunny days, it can operate at full speed continuously. In cloudy or weak light conditions, it can operate at low speed for ventilation. It completely avoids the limitation of socket wiring. There is no need to modify the circuit for outdoor shed installation. This significantly saves electricity costs and construction costs.This solar direct-drive exhaust fan is equipped with a 25W high-efficiency photovoltaic panel. It operates entirely without external power supply from the grid. It runs autonomously to ventilate using natural light. It operates at a 12V low voltage, ensuring safety without any hidden dangers. It is suitable for greenhouse sheds, pet houses, storage sheds, small attics, and RV storage compartments. It can achieve 24-hour autonomous ventilation at a low cost, dispersing hot and unpleasant odors and improving the air quality in enclosed spaces.
The fan uses a 1900 rpm high-speed silent motor, with a running noise as low as 40DB. It will not disturb pets or interfere with daily rest. The overall power is only 5.4W, with extremely low energy consumption. The turbine fan blade and air duct design allow for a large ventilation volume, quickly removing indoor humid and hot air, ammonia odors, dust, and moisture, preventing greenhouse crops from getting spoiled, pet houses from breeding bacteria, and items in storage sheds from getting damp and moldy. The square panel is 25cm in size and fits neatly against the wall. The 4-inch air outlet pipe has good sealing performance, making it difficult for the air to flow back.
A longer power cable with a switch is provided, and it comes with a on/off button on the line. The fan can be started and stopped at any time without disassembly. The DC waterproof connector is not prone to short circuits even when exposed to rain, and the line length is sufficient for flexible adjustment of the solar panel's placement angle to align with the sunlight for improved power generation efficiency. The solar panel comes with an adjustable bracket, allowing it to tilt freely towards the direction of sunlight. Installation is simple, and it can be fixed on walls, roofs, or scaffolds.
The applicable scenarios are extensive: vegetable and flower greenhouses for risk control and temperature regulation, pet houses for odor removal and ventilation, storage sheds for moisture prevention and dehumidification, RV storage compartments for heat dissipation, and small factories for exhaust of stale air. The 12V low-voltage design is safe for the elderly and pets, with no risk of electric shock. The entire machine has a plastic shell that is waterproof and resistant to sun exposure, and it is not prone to aging or cracking when used outdoors for a long time. It relies on solar energy for autonomous circulation of fresh air, solving the problem of hot and unpleasant odors in various enclosed spaces with just one set.
