Solar panels(more specifically:photovoltaic modules) are a collection of solar cells.They are devices used to collect and store solar energy by the photovoltaic effect. A simple explanation of solar cells is that:
1. photons in sunlight are absorbed by semiconducting materials like silicon
2.Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. The complementary positive charges that are also created (like bubbles) are called holes, and flow in the direction opposite of the electrons in a silicon solar panel.
3.An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity.
They are potentially one of the greatest possible solutions to our gas dependency due to the extreme amount of energy that the sun gives off daily.
