Optimizing PV Power Output with Higher-Voltage Modules: A Comparative Analysis with Traditional MPPT Methods

Table 3

Power and cost analysis during Low irradiation.

Types	Irradiation value (Watts/m^2)	Max possible power per hour (20 kWh panel)	Power extraction per hour	Power extraction per year (3.5  365)	Cost per year (1 unit-Rs.8)
Without MPPT	250 W/m^2 to 350 W/m^2	10 kWh	—	—	—
INC method			4.1 kWh	5237.75 kWh	Rs.41902
PI INC method			5.1 kWh	6515.25 kWh	Rs.52122
