Photovoltaic Panel

Photovoltaic is one of the popular technologies of renewable DG units, especially in the MGs. The photovoltaic panel is a solar system that utilizes solar cells or solar photovoltaic arrays to turn directly the solar irradiance into electrical power. In other words, photons of light are absorbed in photovoltaic arrays and thus electrons are released in the panel.
