Calculations
A. String Voc at Low Temperature 42.25V
The module Voc (39.48V) will increase to 42.25V at the design low
temperature (0°C).
(0°C - 25°C) X -0.111V/C + 39.48V = 42.25V
The total Voc for the string is 42.25V.
42.25V X 1 = 42.25V
B. String Vmp at High Temperature 27.42V
Estimated cell temperature equals the design high temperature (33°C)
plus 35°C (the estimated difference between ambient temperatures and
the cell temperature for a flush roof mount).
33°C + 350C = 68°C
The module Vmp (32.19V) will drop to 27.42V at the design high
temperature (33°C).
(68°C - 25°C) X -0.111VIC + 32.19V = 27.42V
The total Vmp for the string is 27.42V.
27.42V X 1= 27.42V
Validation Tests
The minimum Vmp must exceed the minimum PASS
input voltage of the connected device
27.42V> 8V = We
=The maximum Voc must not exceed the max input I PASSI
<48V = true
