Standard Test Conditions (STC) of a Photovoltaic Panel
In past years, a 38 cell panel was much more expensive than a 33 cell panel even though they had the same ampere generation. So if you had a short run of wire you could get all the amperage that the cells were capable of. But if the wire was long or thin, its resistance would decrement the amount of amperage reaching the battery.

Influence of shunt resistance on the performance of solar photovoltaic cell
Connecting Photovoltaic (PV) cells to form an array can cause difficulties when the characteristics of the cells are not synchronized. Shunt Resistance (RSH) plays an important role in the performance of a PV. The leakage current resistance absorbs more current, due to that the current flows through the load circuit is reduced significantly. …

60 cell vs. 72 cell solar panels: Which is right for you?
72-cell solar panels have more photovoltaic cells, therefore, they are larger than 60-cell panels. When it comes to dimensions, 60-cell panels are usually built six cells wide and ten cells tall. 72-cell panels are also six cells wide but have an additional two rows of cells that make them a bit taller.
