The solar fan uses the solar panel to charge the battery. If the light is enough, the solar panel generates current and voltage under the light to charge the battery. The battery emits electricity to the load.

The solar fan can only generate electricity during the day, and if you want to consume electricity at night, you can store the electricity generated during the day with the battery and save it for use at night. Do not use it with intermittent charging in the sun. Pay attention to the ambient temperature when using it. Do not cover objects on the solar panel when using it, and do not use corrosive solutions to wipe it. For more information about the solar fan, please read the following article.

The traditional exhaust fan is powered by electricity, and the electricity cost after use is no lower than that of air conditioning. In this regard, the solar fan obviously has a big advantage and can save a lot of money. It is efficient and energy saving. The bigger the sun, the better the ventilation effect.

The solar fan can only generate electricity during the day, and if you want to use electricity at night, you can use the battery to store the electricity generated during the day and save it for use at night. Do not use it with intermittent charging under the sun. Pay attention to the ambient temperature when using it. Do not cover any objects on the solar panel when using it, and do not use corrosive solutions to wipe it.

When the solar fan's battery is fully charged, electrical appliances with a power of about 50 W for 3-4 hours can be used, such as small TVs, fans and laptops with a total power of less than 300 W.
