The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.

To create solar energy, sunlight must hit your panels'' photovoltaic cells. The sunlight sets electrons in motion, producing direct current (DC) electricity. Your array is connected to an inverter or multiple inverters, which convert the DC electricity generated by the solar cells in your panels into usable alternating current (AC) electricity.
Shading of a Cell in a Module. An individual solar cell has an output of 0.5 V. Cells are connected in series in a module to increase the voltage. Since the cells are in series, the current has to be the same in each cell and shading one cell causes the current in the string of cells to fall to the level of the shaded cell.

The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.
