This document provides instructions for using PVSYST 6 software to model a photovoltaic (PV) system. It outlines the mandatory and optional inputs needed, including location details, technical specifications, and orientation parameters. It then describes how to enter location details using geographic coordinates or address and import meteorological data. Steps are provided for optimizing the tilt angle to minimize radiation losses and module placement to limit shading losses. Recommendations are made for string configuration and inverter selection. The user is instructed to input ohmic loss fractions between certain ranges to model losses from the array to inverter and inverter to point of injection.

- 2. Mandatory • Orientation • System • Detailed losses Optional • Horizon • Near Shading • Module Layout • Economic eval. • Miscellaneous tools
- 4. Location details 1. Coordinates: Latitude (N or S) & Longitude (E or W) Or Address 2. Pin code ,State & Country Technical details 1.Type of system : On Grid /Off grid 2. PV Module technology : Mono/Poly/Thin-film 3.Module Capacity :Wp or make 4. Inverter : Type ,Capacity, Make
- 5. latitude(N or S) /Longitude(E or W) & Altitude(in Meter ) (0° = South Reference (+ Angle for Clock wise (- Angle for Anti clock wise Don’t go any where, Just use this feature in PVSYST 6 Follow the steps Databases Click on geographical site Choose new option Go to Interactive Map section •Enter your Location How it looks like
- 6. Database Click on geographical site Go to New option Choose Interactive Map & Enter location /lat long on address bar then click on Import Go to Geographical Coordinate section &Verify details ,choose Meteodata source i.e Meteonorm6 or NASA-SSE Click on Import>in Monthly meteo section ,click on OK button Save the file
- 9. Fixed tilted Plane Loss by respected to optimum should be 0% Global radiation on collector plane Tilt angle Loss by respect to Optimum(%) Global radiation on collector plane (kWh/m²) 29 -0.1 2224 30 -0.1 2226 31 0 2227 32 0 2227 33 0 2227 34 0 2227 35 -0.1 2226
- 10. • 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 loss %> Change the Pitch value till the shading losses limit up to 1.40% >Exit from orientation
- 12. 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 )
- 14. 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.
- 15. 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%
