Are modules and panels the same thing? Structure of a photovoltaic modules.


Yes, these terms can be used interchangeably. A module or panel is a set of interconnected photovoltaic cells that produce electricity in the form of direct current.

The term “panel” appeared in Poland as an English loanword and has been in use on our market for several years.

It is also useful to know what a photovoltaic cell is. It is a single junction of P-type and N-type semiconductors that converts solar energy into electricity. The cells, often called wafers, generate a low DC voltage when exposed to light. For the most common silicon cell, it is about 0.6 V. To obtain a useable voltage (around a few dozen volts), the wafers are connected in rows by solder or glue. The standardised number of 60 silicon cells can achieve around 40 V. The voltage of a single cell will vary depending on the material of the semiconductor. Therefore, string lengths vary, which directly affects the electrical performance of the entire photovoltaic module.

Strings of cells are often connected in parallel to obtain more power for the entire module.

A module is a collection of individual cells, so the wrongly derided name, “photovoltaic cell battery,” is the correct one.

In contrast, the term “solar collector” should not be used as it means a device used to convert solar energy into thermal energy.
