Series, Parallel & Series-Parallel Connection of PV Panels

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.

Calculation & Design of Solar Photovoltaic Modules & Array

When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
