Fresh Questions, Practical Answers: PVsyst Q&A Series #6

The PVsyst version used for the following Q&A is 6.66 or 6.67, and other versions can be referenced for guidance 1. When the installed capacity of photovoltaic (PV) systems exceeds 1MW, clicking the Layout button for PV module arrangement will result in the pop-up alert box shown in Figure 1. How can this be resolved? ▲Figure 1 [Answer from Teacher Chen]: The hidden parameter settings interface of the PVsyst software imposes certain restrictions on the photovoltaic installed capacity to be simulated. As shown in Figure 2, open the main interface of PVsyst software, click on the menu bar "Preferences" → "Edit hidden parameters", and select the category (Category) shown in Figure 2. It can be observed that when the photovoltaic installed capacity exceeds 1MW, opening the "Layout" function will pop up a "Warring" (warning). If it exceeds 5MW, then the "Layout" function will be unusable. To solve this problem, the…
