Solar Powered Doghouse Exhaust Fans---How Do They Work?
Dog Palace Solar Exhaust Fan kit. How does solar power work? Solar panels capture the sun's energy and use it to make electricity . The sun releases energy called photons, and the photons travel to earth. When photons hit a solar cell (solar panels are made up of lots of solar cells), electrons are knocked loose from the photons' atoms. The electrical circuits formed by the solar cells generate electricity when the loose electrons flow through them. The silicon solar cells are able to make electrical circuits because they have positive and negative sides, just like a battery--this in and of itself creates an electric field. When conductors (objects or materials that allow the flow of electrical charge; commonly metal) are attached to each side of the solar cell, that forms the electrical circuit for the loose electrons to flow through! Science is wild. Now, if you're really into understanding how this works, read on! If you got what you came for, feel free to scroll past. ...
