A module in a solar panel refers to
Series arrangement of solar cells
Parallel arrangement of solar cells
Series and parallel arrangement of solar cells
None of the above.
Parallel arrangement of solar cells
Quick Summary: A solar module is a factory-assembled collection of photovoltaic (PV) solar cells connected in a combination of series and parallel circuits. This hybrid arrangement is essential to achieve a specific target output voltage (via series connection) and current (via parallel connection) for practical power applications.

Vmodule=ns×Vcell — Voltage addition in series
Imodule=np×Icell — Current addition in parallel
Individual solar cells typically produce low voltage (around 0.5V - 0.6V). To increase voltage, cells are connected in series. To increase the total current capacity, these series-connected strings are then connected in parallel. This combination optimizes the Power-Voltage (P-V) characteristics of the module to match load requirements.
Series connection increases the total output voltage of the panel.
Parallel connection increases the total current and enhances reliability under partial shading.
Bypass diodes are often integrated to manage the effects of shading on cells in series.
A module typically consists of 36, 60, or 72 cells depending on the application.
Customizable voltage and current ratings.
Redundancy; failure of one cell path does not always result in zero output.
Complexity in manufacturing and wiring.
Mismatch losses can occur if cells have slightly different electrical properties.
Residential solar power systems.
Remote industrial power monitoring.
Solar arrays are formed by combining multiple modules together.
Option A and B are incomplete as they describe only one type of interconnection method.
C is correct — A solar module uses a combination of series and parallel connections to achieve desired electrical output specifications.
In competitive exams, always remember that series links increase voltage and parallel links increase current; modules are essentially the base building blocks of a full PV array.
