Solar Photovoltaic Panel Application Circuit

How does a photovoltaic (PV) residential system work?

This example shows the operation of a photovoltaic (PV) residential system connected to the electrical grid. The PV strings section implements a home installation of six PV array blocks in series that can produce 2400 W of power at a solar irradiance of 1000 W/m2.

What is a photovoltaic (PV) cell?

A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.

What is a solar PV module?

Mathematical formulation of solar PV module A solar cell is a fundamental device for conversion of photon energy into pollution-free electricity if this device is connected in series and parallel fashion than PV module is formed.

What is an equivalent circuit for a solar cell?

If you want to carefully analyze the behavior of a circuit that includes a solar (aka photovoltaic, or PV) cell, you need to use an “equivalent circuit”—i.e., you need to replace the cell with a group of basic components that can produce similar electrical behavior. This is the equivalent circuit for a solar cell:

How does a photovoltaic cell work?

It is based on the generation of electron-hole pairs in a semiconductor material illuminated by solar light. typical silicon photovoltaic cell generates an open circuit voltage around 0.6-0.7 V with a short-circuit current density in the order of 0.5-0.6 mA/mm2.

How is a PV module's I-V curve generated?

A PV module's I-V curve can be generated from the equivalent circuit (see next section). Integral to the generation of tie I-V curve is the current Ipv, generated by each PV cell. The cell current is dependant on the amount of light energy (irradiance) falling on the PV cell and the cell's temperature.
