“How do solar panels produce energy?”

 

If you live in a sunny part of the world (such as California) then you probably have seen solar panels installed for all sorts of purposes. However, have you ever wondered what exactly causes them to work? Well, let’s explore. If we look closely, then it turns out that solar panels are composed of small solar cells stacked in arrays. These solar cells have semiconductors embedded in their build, so any photons that hit the solar panel will be absorbed. These photons will excite the electrons of this semiconductor to move, inducing a current. This current can then be used to power electrical devices, therefore enabling solar power generation!
