Nimomo 5W Solar Panel Practical Solar Panel Board with Ventilation Fan for Greenhouse Pet House Kennel Cooling

Outdoor solar panels, made of monocrystalline silicon material, efficiently convert sunlight into electricity. When connected to a solar panel, the fan can run without using a rechargeable battery. The sunlight produces hot air, and the solar fan turns immediately to dissipate heat in time and provide ventilation. If you need the solar fan to work at night, you can use a power pack, which is easy to install and use.
