Let’s watch this video on how solar panels work.
So how does it work…
Silicon in Solar Cells
Solar panels are made from solar cells, which are normally made from silicon. Silicon is the second most abundant element on earth.
In a solar cell, crystalline silicon is placed between conductive layers. When the light photons from the sun hit the solar cells, electricity is generated.
Electrons are the only moving parts in a solar and they go back where they came from. There is nothing to get worn out or used up. Therefor a solar cells can last for decades.
