Alternatively, a more accurate correction factor for the open-circuit voltage can be calculated using the
following formula:
C
Voc
= 1 − ∝
Voc
× (25 − T)
T is the lowest expected ambient temperature at the system
installation site.
α
Voc
(%/°C) is the voltage temperature coefficient of the selected
module (refer to corresponding datasheet).
Electrical calculations and design must be performed by competent
engineer or consultant.
