PV cells are connected either in series, parallel or a combination of the two. There are some obvious reasons as to why this might be done for example to achieve different currents, voltages and shade resistance.

I have been thinking about how PV panels might be connected for different applications. For example, how would the PV panels on the Mars rover be connected as opposed to a PV panel on the roof of a house and why is it done as such?

I would appreciate some help in understanding this, I have tried looking for some academic/research papers on this but did not find anything which answers the ‘how’ or ‘why’ PV cells might be connected in a certain way to achieve a certain outcome.
