PV array power at a common operating point calculator

Voltage and current must be measured at the same operating point rather than mixing open-circuit and short-circuit values.

PDC=V×IP_{\text{DC}} = V \times I

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Worked example

Given

  • VV = 310 V
  • II = 24 A
PDC=310×24=7,440P_{\text{DC}} = 310 \times 24 = 7{,}440
