Photovoltaic Array Fundamentals
Photovoltaic Array Fundamentals. The physics of the PV cell is very similar to the classical p-n junction diode. When light is absorbed by the junction, the energy of the absorbed photons is transferred to the electron system of the material, resulting in the creation of charge carriers that are separated at the junction.
The Different Types of Solar Photovoltaic Systems
1) Grid-Connected Solar Photovoltaic Systems. A grid-connected solar photovoltaic (PV) system, otherwise called a utility-interactive PV system, converts solar energy into AC power. The solar irradiation falling on the solar panels generates photovoltaic energy, which is DC in nature. Using a DC-DC converter, the total photovoltaic DC voltage ...
