Difference between String and Array in Solar Panels
What is the Difference between Solar Cell, Panel, Array and Module? A solar panel is the same as a PV (photovoltaic) module. A solar panel is made up of several semiconductors called cells. There are 36 cells in a typical solar panel like the Sonali 190W 12V. When the sun strikes the cells, the energy is converted into direct current electricity.
