• The shading losses should be in limit ≤1.40% Module Placement on tilted plane
If module mounting is Portrait : Enter the (L)length (in meter) If module mounting is landscape : Enter the (W)width (in meter) (check out these dimension from Module sheet )
Show Optimization shading losses limit up to 1.40% >Exit from orientation
Shading loss %> Change the Pitch value till the
string ,Central or micro based on economics(investment/Wp) , ease of installation and efficiency ,No of mppt , make ,% loading on inverter (oversized or under size )
Go to DC circuit: ohmic losses for the array > click on loss fraction at STC > Enter the value in between 1.10% -1.30% (these losses computed considering ohmic losses of array to String combiner box and String combiner boxes to Inverter) These loses occur due to resistance of DC wire in the Module strings to String combiner box/String Monitoring box and string 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 0.50% -0.80% (these losses occur at Inverter output to Point of injection of energy in to the grid (switch yard). The losses include Ohmic loss in 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 metering panel as per PPA & respective state regulations. The voltage drop should be below 2.1%
