What is a solar PV module?

A solar PV module is a collection of solar cells, mainly connected in series. These combinations of Solar Cell provide higher power than a single solar cell. The PV modules are available in the power rating range from 3 watt to 300 watt. They really from the basic building block of PV systems as power generating unit.

How to estimate the number of solar cells in a PV module?

Thus, in order to estimate the number of cells in a PV module, one can use following steps : Step 1 : Find out the V m (STC) of a solar cell of given technology (if V m is not given, it can be estimated by Voc); the PV module parameters V m and Voc) are discussed in the next section.

What size solar cells are available?

The crystalline Si cell technology is the most commonly used technology. For this technology, the large area solar cells are available in either size 12.5 X 12.5 cm2. Or 15 X 15 cm2. These size of solar cells are commonly used, particularly, in all modules which are used in grid-connected PV plants.

How many solar cells are in a solar module?

A solar cell is the basic building block of a solar module. Each cell produces approximately 1/2 a volt and a solar module can have any number of solar cells. A solar module designed for charging a 12 volt battery will typically have 36 solar cells while the typical residential grid connected system uses solar modules with 60 solar cells.
