RATEDPOWER VS. PVSYST

Do more than the energy yield

We asked our best sales and customer success teammates this same question: “What are the most relevant differences between RatedPower and PVsyst?“. They gave us a handful of clear answers that should help you.

RATEDPOWER VS. PVSYST

What’s the difference between RatedPower and PVsyst?

PVsyst is a software used for studying photovoltaic systems focusing on architects, engineers and researchers. They focus on measured results, energy and economic analysis and project bankability. The software cannot be installed on a server, remote desktop or an Azure virtual desktop machine. Check out this comparative table to learn more about how you can add value to your projects and teams with RatedPower.

PVsyst
Meteo data
Up to 15 min time step meteo data input included in simulation and project performance analysis. Model under 15min weather variations and their impact on energy production.
Provides access to hourly, 15min, 5min and 1 min resolutions. This allows for detailed performance analysis and system optimization under varying weather conditions.

The flexibility in data resolution helps in creating accurate simulations that are crucial for optimizing system design and maximizing energy yield, whether for small installations or large-scale projects.
Comparison Tool
Comparison of simulation with measured results. However, access to this tool can be limited depending on the licensing terms, which may restrict its use for some users.
Offers a seamless, software-embedded option for comparing different project simulations and designs. This tool allows users to assess the impact of various design parameters, such as pitch and DC/AC ratios, on system performance. The comparison tool is available without restrictions, providing unlimited access and facilitating collaboration among team members. This feature is particularly useful for iterative design processes and optimizing PV systems through comprehensive comparative analysis.
Deployment
The software runs on Windows and requires virtual machines to operate on other systems like macOS or Linux. This can add complexity to the installation process and may require additional IT resources for setup and maintenance.
The software is cloud-based, which ensures that users can access the software from anywhere, facilitating remote collaboration and real-time updates. This accessibility is particularly advantageous for large teams working on multiple projects simultaneously, streamlining workflow and reducing the need for complex IT infrastructure.
Energy Yield
Provides manual energy yield estimations to be used to evaluate project bankability.
Includes an embedded energy yield estimation tool within the software, which performs comprehensive calculations. This tool streamlines the process of predicting energy production, allowing users to quickly and accurately estimate the potential yield of their PV systems.
Calculations
Detailed energy and economic analysis. However, based on users' feedback, there are limited optimization capabilities, and it is complicated for new users. Additionally, it is not a user-friendly tool for those without experience, especially when it comes to layout definition and shading scenes creation.
Includes tools for detailed calculations, covering elements such as earthwork, electrical layout, cable sizing, SLD, BOQ, and auto-optimization of design layouts. These features allow users to perform thorough evaluations and optimizations of their PV systems. Layout calculations and simulations are streamlined and performed automatically in less than 60 seconds.

An energy yield +0.24% different to PVsyst

Energy yield modeling is a mix of hard data and thorough scientific-led methodology. Specific yield or annual degradation are common results in any energy yielding software, such as PVsyst or their alternatives.

We turned to Black & Veatch to compare RatedPower's energy yield module to PVsyst output in four real-life cases. Deltas range between +0.24% and +1.08%. Related detailed yielding documentation is available in both tools.

We've got you covered

RatedPower's software can serve as an alternative or complement to PVsyst, offering additional functionalities such as in-depth calculations for battery storage (BESS), topography analysis, earthworks, and more. While PVsyst primarily focuses on energy yield calculations with a single report of yield data simulation, RatedPower provides built-in modules for feasibility analysis, conceptual design, and proposal generation in addition to energy production calculations.

No, PVsyst is not a cloud-based software. It requires installation on the workstation where it will be used, with one license required per computer. In contrast, RatedPower is a cloud-based software, enabling faster simulations and calculations and eventually saving up to 90% of the time spent by engineering teams.

The RatedPower software is used to get quick estimations on site location, inverter selection, grid point, electrical configuration, amongst others. You can leverage additional calculations like BESS-Coupling, topography, sub-hourly meteo data, etc.

Through our software you can export your designs and projects to CAD and other compatible software. You can use the software on any device and system (Microsoft, OS, etc.).

Our dedicated team of technical experts is readily available to support you with your questions. In addition to that, we have dedicated explanatory materials at your disposal. Talk to a sales representative or check out our knowledge hub section.

We listen to and value our customers’ feedback and believe that it’s the core of our software development. How do we do that? Through ongoing surveys, and dedicated meetings to collect insights on what we should continue doing and what we should improve or add to make our software more complete.
