【2 Ways Power Supply: Solar(Priority)+ Electric(Secondary)】A smart power controller is included to allow automatic switching of the powe supply between solar panel and AC/DC power adapter. Solar power works when solar energy is equal and greater than 14V; solar + electric work together when solar energy is greater than 0 but less than14V; electric power works when solar energy is 0V. This Solar Fan even works on rainy days!
Quite and waterproof brushless DC motor, 14in nylon-fiber-aluminum blades (7 blades not 3 ), galvanization steel housing and mounting frame, solar wall exhaust fans can be assembled Together(Note: please buy extra screws ), front side metal mesh, roof/wall mounted
【Adjustable Solar Panel】: Horizontally & Vertically (15/30/45 degree. So you can make sure the sun is directly opposite the solar panel. Besides, the panel could be Remote Mounted

2 Ways Power Supply: Solar(Priority)+ Electric(Secondary)
A smart power controller is included to allow automatic switching of the powe supply between solar panel and AC/DC power adapter.
Solar power works when solar energy is equal and greater than 14V;
solar + electric work together when solar energy is greater than 0 but less than14V;
electric power works when solar energy is 0V.
7 Fan Blades
1. On Amazon marketplace, most solar exhaust fans only have 3 blades. But, our GBGS solar exhaust fans have 7 blades. So, our noise is as low as 40db while working.
2. Mounting frame design: several solar exhaust fans can be assembled together.(Note: Please buy extra screws)
3. Front side metal mesh: can stop insects from coming in.
Adjustable Solar Panel
Horizontally & Vertically (15/30/45 degree. So you can make sure the sun is directly opposite the solar panel.
47.5 ft Power Cable
Long power cable enable you to flexibly install the solar exhaust fan. The panel could be remote mounted
