Max Solar Voc and Pmax Calculation Form

Total string OC voltage (V):
Rated Voc of the panel times the number of panels in series.
(The rated Voc can usually be found on a sticker on the back of the panel)



Total string nominal maximum power (W):
Rated nominal maximum power of your entire string.
(Typically the number your panels are advertised at)



Worst case temperature (C):
The lowest temperature expected
(Typically the historic low for your location)



Voc Temperature coefficient (%/C):
The rated temperature coefficient (for Voc) of the panel
(The rated Temperature coefficient can usually be found on a sticker on the back of the panel)



Pmax Temperature coefficient (%/C):
The rated temperature coefficient (for Pmax) of the panel
(The rated Temperature coefficient can usually be found on a sticker on the back of the panel)
