Go to DC circuit: ohmic losses for the array > click on loss fraction at STC > Enter the value in betwee(these losses computed considering ohmic losses of array to String combiner box and String combine

These loses occur due to resistance of DC wire in the Module strings to String combiner box/String Monstring combiner box to Inverter DC input.

Go to AC circuit: Inverter to injection point> click on loss fraction at STC > Enter the value in between(these losses occur at Inverter output to Point of injection of energy in to the grid (switch yard). The loss

Inverter output to LT panel ,LT panel , HT panel .)

*Transmission line losses are not included on this because it depends upon the point of injection /Joint m& respective state regulations.

The voltage drop should be below 2.1%
