Powerful Solar Generation Simulation with Detailed Probability based Outputs **Rating:** 4.0/5.0 stars **Reviewed by:** Shashikant y. | Engieering Manager(Solar + BESS)- India and Southeast Asia, Small-Business (50 or fewer emp.) **Reviewed Date:** March 24, 2026 **What do you like best about PVsyst?** It simulates a grid-connected or islanded solar power plant and provides the expected generation with different probability levels (P50, P75, P90, P95, P99, etc.). Depending on the data source used, you can obtain monthly generation, hourly generation, or even minute-by-minute generation. **What do you dislike about PVsyst?** Importing the 3D file into PVsyst is challenging for me because it often leads to errors. Also, when I create a PVC file from the rated power and import it into PVsyst, an additional orientation is created automatically. This extra orientation is different from the one I set up in the system itself, and with these two orientations the results come out differently. Another issue is partitioning. When defining the partitioning in PVsyst, different types of partitioning give different results for electrical shading losses. For example, for 2P modules (two modules in portrait), what I usually follow is 4 partitions on the Y-axis and 2 partitions on the X-axis for a 60-module table, which should form two strings. However, I have seen simulations from Big5 using different partitions and getting different results. One more problem I observed is that with ground and without ground results are different which should not be the case **What problems is PVsyst solving and how is that benefiting you?** It provides monthly, daily, hourly, and even per-minute generation data for a solar power plant, which is very useful for developers and IPPs. I work as an IPP, and I find this especially helpful. It also allows users to enter different types of losses as inputs—such as soiling loss, DC and AC ohmic loss, mismatch loss, unavailability, power factor, aging, etc.—and their impact is then reflected in the final generation report. ### 2.
