Figure 7 Shading scene for PV determined on 3 degree sloping facing south 22. Select FileClose.This will return you to the near shading window Note If you already have a built shading file you can load it directly into the Near Shading window by clicking the Open button under the model library heading, and selecting the near shading scene. Only files that are located in the file location CProgram DataPV systDataShadings can be opened. 23. Select the Table button to generate the shading factors calculated from the model just built. at once generated close the window. 24. You can view the set up of the shading on an Iso-shading curve by selecting the Graph button located under the Linear (rough) Shading Factor heading.Figure 8 presents the results. 25. In the Near shading pop-up window select Ok to continue. Figure 8 Iso sh ading diagram from PV-SYST for the shading model built 26. In the Project window now select the System button. This will open up the Grid system definition window 27. In the Grid system definition window select or available area as the method to define the system size. Type in 54m2. 28. In the Project Design mode you have the ability to select the actual brand, type and size of module you want in your system. 29. For this tutorial select Sort Modules by Power.The PV Modules are then ordered by double-u peak output and voltage. You can choose which ever module you would like to scrutiny for your system. For this tutorial, lets select the sunshinePower 200Wp 34V Si-mono Modules. 30. The succeeding(a) step is to select the inverter. Sort the inverter angle via Manufacturer and scroll down to the top of the available sun Power inverters. Note PV-SYST can automatically determine the number of modules in series and the number of thread per inverter, and the number of inverters requi red, based on your module and inverter selection.It should be noted however, that the majority of gangs are not compatible. PV- SYST has a grey index finger box, as highlighted by the green self-colored in Figure 9 that provides detail about your chosen combination. For example, if a heart in red text is displayed, the combination chosen is not viable, i. e. The Sun Power models we chose in combination with 30kW 420-800V Sunways inverter achieve a message that reads The inverter power is strongly outsize. If a message in orangish text is displayed, the combination is potentially viable, but there are likely to be better combinations. . e. The SunPower models we chose in combination with the 3. 3kW 195 550V SunPower inverter achieves a message that reads The inverter power is slightly oversized or with the 5. 2kW 240-450V Sun Power inverter achieves an orange message that reads The array Vmpp at 60C is lower than the inverter minimum operating(a) voltage. The best combinations of PV modules and inverters occur when no message is received. For example the combination of the Sun Power modules we chose with the 4kW 195-550V Sun Power inverter. 31.Choose the Sun Power inverter that is rated at 4kW 195-550V SPR-4000x 32. This combination of PV modules and inverter results in a system that requires two inverters, with 7 modules in series and six strings. 33. Select OK to continue 34. In the Project window select the Simulation button. This will open the Simulation pop-up window. 35. Accept the default parameters and click on the Simulation button to begin the counting process. 36. Click the OK button once the simulation calculation process is complete. This will bring up the Results window
