A PV module is made up of many PV cells.

• A. One cell
• B. Many cells in a module
• C. Several strings
• D. A single junction

Answer: (B)

A PV module is built from many PV cells to produce useful electrical output. A single cell generates only a small voltage (roughly 0.5 V) and limited current, so connecting many cells together increases the overall voltage and current to usable levels. In a module, cells are arranged in strings (series to add voltage, sometimes parallel to add current) and then grouped to form the complete panel. This is why the correct idea is that a module contains many cells. Think of it like stacking multiple tiny voltage sources to reach the voltage you need, while combining enough cells in parallel paths to supply the required current. The other ideas don’t fit the structure of a module: it isn’t just one cell, the module isn’t simply several independent strings, and a single junction refers to the internal feature of a cell, not the whole module.
