Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. Beginning with the fundamentals, it discusses photon energy, P-N junctions, the photovoltaic effect, and the. .

Polycrystalline solar panels work by using multicrystalline silicon cells to absorb sunlight and convert it into electricity. This is a result of the photovoltaic effect, where electrons within the cells of the panel are knocked loose as a direct result of contact with sunlight. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels.
