What is a photovoltaic module?
Photovoltaic modules (Figure 2) are interconnected solar cells designed to generate a specific voltage and current. The module's current output depends on the surface area of the solar cells in the modules. Figure 2. A flat-plate PV module. This module has several PV cells wired in series to produce the desired voltage and current.
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.
How much voltage does a crystalline PV module produce?
In crystalline modules, the amount of voltage produced is ~0.5V per cell, regardless of size. Therefore, module manufacturers must place multiple cells in series to produce the desired voltage and current values from their modules. In addition to physical size, the amount of current produced from PV cells is dependent on the sunlight intensity.

What is the voltage of a PV module?
Let us understand this with an example, a PV module is to be designed with solar cells to charge a battery of 12 V. The open-circuit voltage VOC of the cell is 0.89 V and the voltage at maximum power point VM is 0.79 V.
How much current does a PV module produce?
In addition to physical size, the amount of current produced from PV cells is dependent on the sunlight intensity. This means PV modules cannot provide an unlimited amount of current when a dead short scenario occurs, which is an important consideration when calculating conductor and OCPD sizes.
