The voltage from the PV module is determined by the number of solar cells and the current from the module depends primarily on the size of the solar cells. At AM1.5 and under optimum tilt conditions, the current density from a commercial solar cell is approximately between 30 mA/cm 2 to 36 mA/cm 2.
The following figure shows solar panels connected in parallel configuration. If the current IM1 is the maximum power point current of one module and IM2 is the maximum power point current of other module then the total current of the parallel-connected module will be IM1 + IM2.
A solar module, also known as a solar panel, is a single photovoltaic panel made up of connected solar cells. To generate electricity, solar cells absorb sunlight as a source of energy. To power buildings, a variety of modules are employed.
Single crystal solar cells are often 15.6 × 15.6 cm 2, giving a total current of almost 9 – 10A from a module. The table below shows the output of typical modules at STC. I MP and I SC do not change that much but V MP and V OC scale with the number of cells in the module.
To increase the current N-number of PV modules are connected in parallel. Such a connection of modules in a series and parallel combination is known as “Solar Photovoltaic Array” or “PV Module Array”. A schematic of a solar PV module array connected in series-parallel configuration is shown in figure below. Solar Module Cell:
The voltage of a PV module is usually chosen to be compatible with a 12V battery. An individual silicon solar cell has a voltage at the maximum power point around 0.5V under 25 °C and AM1.5 illumination.
