Solar mini exhaust fan is very suitable for camping, RV, chicken house, dog house, greenhouse, roof, , , etc. The solar panel fan kit can push out hot air and suck in cold air, thereby effectively reducing the indoor temperature and keeping the air fresh. The solar panel adopts monocrystalline silicon material, which is to pressure and . High conversion rate, high efficiency and energy saving, no power storage function The cooling fan is powered by a solar panel, which is easy to install. You only need to connect the solar panel and the fan interface, and then put it in the sun. The solar panel runs the fan quickly under direct sunlight. When the sunlight is weak, the solar fan will or stop working. The solar fan ventilator is convenient to carry, green energy, and energy saving, and recyclable. Just connect the boundary of the solar panel and put the solar panel in the sun to use. It can reduce cooling costs and lower electricity bills. The monocrystalline solar charger is a device that absorbs sunlight and converts it directly or indirectly into electrical energy through photoelectric or photochemical action.
