Inverter Selection
๏ Pre decide the type of inverter i.e. string or central.
๏ Go to > Select the inverter make from the list > sort the inverter based
on Power or Voltage.
๏ Inverter should be sized in such a way that under loading & over
loading (DC to AC ratio) with in acceptable range.
๏ A message will appear on dialog box i.e. indicate if there is any error
during the selection of inverter.
๏ Go the design the array > check no of modules, modules in series &
module string.
๏ Click on OK > Proceed the next steps.

Losses
Ohmic losses
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 / string monitoring box and string
combiner box to inverter DC input.)
These losses occur to due to resistance to DC wire in the Module string to string
combiner box / String monitoring box and string combiner box to inverter DC input.

Losses
AC Ohmic Wiring losses
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 into the grid (switch yard). The losses
include Ohmic losses in inverter output to 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
regulation.
The Voltage Drop should be below 2.1%.

External Transformer
โข Go to external transformer > iron loss > enter 0.10% or enter Fixed loss
of transformer if known.
โข Resistive/ Inductive losses > enter 0.10%
โข Iron loss : are fixed losses of transformer occur due to hyterersis and
eddy current loss in the core of transformer. Silicon is used to reduce
these losses.
โข Ohmic/ Inductive loss: are variable losses due to resistance /
Inductance of copper winding and loading of the transformer.

Module Quality Loss
Go to module quality loss section > Enter the value the according to
average deviation of the module tolerance power is positive +3% then
module quality loss shall be +3/2= 1.5%.

LID Light Induced Degradation
Initial degradation of solar PV module occurs in the very first hours of
operation in the actual site. After certain period of time (3.4 months) the
power output of the module stabilizes on the certain level compare to STC
power.
Typically poly C-Si Module degrade @1.0%
Mono C-Si Module degrade @ 1.5%
Thin film Module degrade @ 2%

Mismatch Loss
The mismatch loss is mainly due to the fact that in a string of module, the
lowest current drives the current of whole string. This is due to material
property of Silicon which is used for the PV module manufacturing. Now
when installing real modules in the field, the characteristics of the module
are never rigorously identic.
Power Loss at MPP
The difference between the effective operation conditions and the
maximum available power plant. Foe MPP use (grid inverter) the loss is
neglected in PV Syst. For fixed operating voltage, it can be quantified from
the output simulation result.
Go to mismatch Section > Enter the value (it typically happen at 1%) & loss
when running at fixed voltage not relevant when MPPT operation (it
typically limit to 1.1%)

Soiling Loss
Accumulation of dirt and its effect on the system performance is an
uncertainty which strongly depends on the environment of the system,
raining conditions etc.
Considering the project location in Rajasthan where module are frequent
face the dust/dirt/sand the soiling loss so power loss can be up to 3% and
location like Karnataka/Uttarakhand the power loss can be up to 2%
because of less prone to dust & dirt environment.
This power loss can be reduce by increasing the frequency of module
cleaning.
