Photovoltaic Vs. Solar Panel (What''s The Difference)

Photovoltaic cells make up the structure of a solar panel, but the two have very different functions for the entire solar array. Essentially photovoltaic cells convert sunlight into voltage. Then the solar panel takes that voltage and turns it into usable electricity. Photovoltaic cells are the part of the solar panel that reacts to the sun to
