   * **Nominal 20v panels** have 60 cells.  They will generally have max power (Vmp) around 30v and open circuit (Voc) around 36v.((https://www.altestore.com/howto/solar-panels-pv-and-voltages-a98/))  These are commonly found in residential rooftop installations.
   * **Nominal 24v panels** have 72 cells.  They will generally have max power (Vmp) around 36v and open circuit (Voc) around 42v.((https://www.altestore.com/howto/solar-panels-pv-and-voltages-a98/))  These are commonly found in commercial or residential ground level installations.  Due to internal construction (actually 2 36-cell segments in parallel)((https://youtu.be/ofo1HQyGG8s?t=1m22s)) they can be more resistant to partial shading.
+  * even higher cell counts (and voltages) can be present in very large panels, like >400w.
