Fresh Questions, Practical Answers: PVsyst Q&A Series #12

1. The capacity-matching ratio of the photovoltaic system has been set to 1.42, but the power output limit is set at 1.1%. Is this accurate? [Teacher Chen from Candela Academy]: Currently, PVsyst can effectively simulate and emulate the setting of over-matching ratio and whether there is a limit on loss due to over-matching. As shown in Figure 1, in the system settings interface, we can obtain rough values of overload loss under different Pnom ratios. ▲Figure 1 After the Simulate ends, we can see more detailed overload losses in the "Detailed inverter losses" section of the simulation results, as shown in Figures 2 and 3. ▲Figure 2 ▲Figure 3 2. If there are measured environmental temperature and horizontal plane irradiation data for a certain project site, how can they be quickly imported into PVsyst software for use? [Teacher Chen]: If you have the radiation data for one month and the…
