Correction factor for the open-circuit voltage can be calculated based on the following formula: CVoc=[1-
α(25
-
T)]%. T is the lowest expected ambient temperature at the system location. α(%/°C) is the
temperature coefficient of the selected module Voc(Refer to corresponding datasheet).

Note: The data above are calculated based on the temperature in Wuxi. The maximum number of modules that can be
connected in series within a string for the specific project must be calculated based on the actual local temperature.
If there is reverse current exceeding the maximum fuse current flowing through the module, use over-
current protection device with the same specifications to protect it.
Recommended installation method of full cell solar module:
The modules in PV array are recommended for portrait connecting, and cable length is not less than 0.7 m.
Recommended installation method of half cell solar module:
The head and tail of the modules in PV array are placed in a cross layout, and cable length is not less than
0.65 m.
