"PVsyst - The Solar Generation Software"

4.5/5

What do you like best about PVsyst?

PVsyst has been my go-to software for energy-yield simulations thanks to its accuracy and its detailed modeling capabilities. It lets me assess different system configurations and key factors like losses, shading, degradation, and meteorological data before I finalize a design. I also use SketchUp to build 3D shading scenes, and it integrates smoothly with PVsyst to support more realistic near-shading analysis. Using both tools together improves my design accuracy and gives me greater confidence in my project generation estimates. Review collected by and hosted on G2.com.

What do you dislike about PVsyst?

The software is very powerful, but the interface feels somewhat outdated and it can take new users a while to get comfortable with it. Importing and managing complex SketchUp shading scenes can be time-consuming as well, especially when you’re working with more detailed setups. A more modern UI and a smoother, more streamlined workflow would make the overall experience even better. Review collected by and hosted on G2.com.

What problems is PVsyst solving and how is that benefiting you?

PVsyst helps me accurately estimate energy generation, optimize system design, and identify potential performance losses early in the design stage. As a result, I can make better techno-commercial decisions, reduce project risk, and deliver more reliable generation estimates to clients and other stakeholders.

"Powerful Solar Generation Simulation with Detailed Probability based Outputs"

4/5

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. Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

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.

"Pvsyst: A powerful software for both students and professionals"

4.5/5

What do you like best about PVsyst?

There are a lot of libraries of components and converters related to the PV area, allowing the user to model a wide range of configurations. Nonetheless, this characteristic is enhanced by the user-friendly interface provided. This way, the software is ideal to beginners and for experient users as wel.. Review collected by and hosted on G2.com.

What do you dislike about PVsyst?

The market of photovoltaics is constantly evolving, day by day, with new technologies and techniques. Since the software is paid, it was expected that it could be the most up-to-date as possible. Review collected by and hosted on G2.com.

What problems is PVsyst solving and how is that benefiting you?

I'm a researcher at Federal University of Mato Grosso do Sul and we are doing research about electric stations and smart algorithms to reload vehicles without affecting the grid stability and to sell the energy from the vehicle to the grid when it is benefical from a economic point of view. So the PVsyst help us to evaluate a lot of scenarios, so we can test our algorithm robustness. Review collected by and hosted on G2.com.
