How Solar Panels Work
How exactly do those panels work? Unlike power from a wind turbine or even a power plant, solar panels don’t seem to have any moving parts — so how exactly is that energy being produced?
The simple answer is that solar panels are made up of silicon and conductive metals, which form an electric field. When sunlight hits, the solar energy shakes electrons in the silicon out of their “natural” state, while a circuit attached to the panel is able to generate a current out of those electrons’ desire to return to their original positions within the panel.
Today’s infographic comes from SaveOnEnergy, and it covers the science behind how solar panels work.
While it is fairly technical, the handy animations will help you understand the principles behind photovoltaic cells in no time at all.
