Technical FAQs 4

What is a solar cell string?

Solar cell strings refer to a series-connected group of solar cells within a solar cell module, designed to build the driving force while maintaining the same terminal current. Each string contributes to the total module voltage, which is the sum of the voltages of the individual cells. How useful is this definition?

What is a solar cell module?

The solar cell module is a unit array in the PV generator. It consists of solar cells connected in series to build the driving force and in parallel to supply the required current. A series-connected group of cells are called a solar cell string. Actually, the strings are connected in parallel as shown in Fig. 1.31. Figure 1.31.

What is a solar PV module?

It has been considered all along this work PV modules that are combinations of strings of solar cells manufactured by Solarus AB (38 cells and 4 bypass diodes).

Why do we need a solar cell string model?

Moreover, the modelling can be used to define the solar cell string layout associated to different PV collector configurations in order to improve their performance accordingly with he defined requirements.
