PV Array Requirements
Serial connection (string) of PV modules
As the core component of PV system, controller could be suitable for various types of PV
modules and maximize converting solar energy into electrical energy. According to the
open circuit voltage (V
oc
) and the maximum power point voltage (V
Mpp
) Ot the MPPT
controller, the series number of different types of PV modules can be calculated. The
below table is for reference only.
