Calculations
A. String Voc at Low Temperature 377.46V
The module Voc (39.19V) will increase to 41.94V at the design low
temperature (0°C).
(0°C - 25°C) X -0.11 V/C + 39.19V = 41.94V
The total Voc for the string is 377.46V.
41.94V X 9 = 377.46V
B. String Vmp at High Temperature 245.07V
Estimated cell temperature equals the design high temperature (33°C)
plus 360C (the estimated difference between ambient temperatures and
the cell temperature for a flush roof mount).
33°C + 35°C = 680C
The module Vmp (31.96V) will drop to 27.23V at the design high
temperature (330C).
(68°C - 25°C) X -0.11 V/C + 31.96V = 27.23V
The total Vmp for the string is 245.07V.
27.23V X 9 = 245.07V
Validation Teats
The minimum Vmp must exceed the minimum PASS
input voltage of the connected device
245.07V > 100V = true
The maximum Voc must not exceed the max input PASS
voltage of the connected device
377.46V < 600V = true
