Solar Panel (What's The Difference) While the ordinary layman may not know, there is a vast difference between a photovoltaic cell and solar panels. 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.

What are photovoltaic cells?

To break it down into the simplest terms, photovoltaic cells are a part of solar panels. Solar panels have a lot of photovoltaic cells lined upon them to convert sunlight into voltage. The solar panels use the voltage generated by the photovoltaic cells and convert it into power. Of course, this can become a lot more complicated practice.
