How Solar Energy Panels Work

Solar energy panels contain photovoltaic cells. This is where the energy from the sun is converted to electricity. While there’s quite a science behind it all, here are the basics. Silicon plates are used to allow electrons to flow freely through it. The silicon doesn’t have either a positive or a negative charge, so other elements, usually phosphorus, and boron are combined with the silicon, so the sun’s energy can be captured by the silicon. The photons from the sun bombard those silicon panels and this captured energy is converted into electricity that can be used to power household appliances, small shops, or even a entire home. Solar panels are looped together to create more energy. This is why you see many panels on the roof of a solar powered home.
