Minimum and Maximum number of modules calculator for an MPPT

*The following calculator is for reference only.

Minimum number of modules = MPPT starting voltage / Vmp at max. site temp.
Maximum number of modules = MPPT max. voltage / Voc at min. site temp.

Voc at minimum site temperature (V)
? Voc at min. site temperature is also called Maximum Voc calculated at lowest expected site temperature. If not given already you can use this calculator
Vmp at maximum site temperature (V)
? Vmp at max. site temperature is also called Minumum Vmp calculated at highest expected site temperature. If not given already you can use this calculator
