The powerrequired by our daily loads range in several watts or sometimes in kilo-Watts. A single solar cell cannot produce enough power to fulfill such a load demand, it can hardly produce power in a range from 0.1 to 3 watts depending on the cell area. In the case of grid-connected and industrial power plants, we require.

PV arrays are the most significant part of solar photovoltaic power generation. When light falls on PV arrays, it is converted into a direct current. Each PV cell produces a certain DC voltage and the overall effective voltage and current from the PV array depends on the series-parallel arrangement of the PV cells.
Solar Module Cell: The solar cell is a two-terminal device. One is positive (anode) and the other is negative (cathode). A solar cell arrangement is known as solar module or solar panel where solar panel arrangement is known as photovoltaic array. It is important to note that with the increase in series and parallel connection of modules the power of the modules also gets added.

The connection of the solar panels in a single photovoltaic array is same as that of the PV cells in a single panel. The panels in an array can be electrically connected together in either a series, a parallel, or a mixture of the two, but generally a series connection is chosen to give an increased output voltage.
The size of a photovoltaic array can consist of a few individual PV modules or panels connected together in an urban environment and mounted on a rooftop, or may consist of many hundreds of PV panels interconnected together in a field to supply power for a whole town or neighbourhood.
The circuit design of photovoltaic power generation is impossible without PV modules. PV modules are available in different sizes and varieties. The ones that best suit the space and load of the project should be selected. PV modules are connected in series and parallel to form the PV array.
PV arrays are the most significant part of solar photovoltaic power generation. When light falls on PV arrays, it is converted into a direct current. Each PV cell produces a certain DC voltage and the overall effective voltage and current from the PV array depends on the series-parallel arrangement of the PV cells.
