This laboratory is different from the others in this textbook. It represents an investigation into modeling a photovoltaic cell and, by extension, a PV module and PV array. We will use a software program called PSpice, which will allow us to simulate the performance of a PV cell under the effects of irradiance and temperature. Thus, the “hands-on” part of this laboratory involves the use of PSpice on a Windows computer.
This laboratory has been developed for three reasons.
First, the standard methodology introducing photovoltaics rarely links the behavior of a PV cell (the I-V characteristic, if you will) to an equivalent electrical circuit model. This is unfortunate as the elements ...
