SunDAT Desktop: PV Design Software


SunDAT’s patented system for determining layout maximizes use of space while automatically placing roads or aisles in your designs. Handle the most complex boundaries and obstructions with ease.


Calculate production, yield and performance ratio (PR) estimates within SunDAT and compare different system designs to see which one is the most economically optimal. You can do real-time energy modeling, publish project-specific reports, and export your 8760 data for further economic analysis.


SunDAT is specially adept at dealing with rugged topography. You can identify areas that are beyond a certain slope tolerance, or flag areas in your layout that will need to be graded or avoided entirely. Based on topography analysis, SunDAT also automatically determines row spacing on fixed tilt systems to avoid shading.

SunDAT software is a 3D solar PV design tool primarily for utility-scale and commercial and industrial (C&I) projects. Whether you are designing a C&I rooftop system, large canopy structures, utility-scale PV systems, or even a residential project, SunDAT can help you automate workflows and increase the efficiency of your design process. SunDAT software is engineered to handle large, utility-scale design projects. Aside from designs that will optimize Ground Coverage Ratio (GCR), and engineer enhanced yields on rough terrain, SunDAT is specially adapted for solar trackers, bifacial modules and other solar technologies that boost energy production.  

  • Automate Your Design Workflow

    Using SunDAT solar PV design software, you can improve the speed of your design process. Through our patented layout feature and automated scripting you can record repetitious steps you use in your design process and use them again - perfect for companies that have a lot of projects in the pipeline.​

  • NREL's System Advisor Model (SAM)

    The SAM model is built into the SunDAT software. Taking into account both the technical and economic aspects of your project, the NREL SAM model can help you compare the economic potential of different system designs and evaluate their financial performance.

  • Component Library

    The SunDAT library offers hundreds of components from key manufacturers worldwide for modeling in your SunDAT design projects. Choose from modules, inverters and other equipment to get the most accurate estimates for production and cost.
