General Description


SunDAT is one of the solar industry’s foremost commercial-scale 3D design tools. 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 achieve maximum efficiency in your design process. There are no limits on the size of the projects you can design in SunDAT. 800 MW? No problem! Aside from designs that will optimize Ground Coverage Ratio (GCR), and engineer maximum energy yields on rough terrain, SunDAT is specially adapted for solar trackers, bifacial modules and other technologies that maximize return on investment. 



Features


Automated layout design


    SunDAT's patented system for determining layout maximizes use of space while automatically placing roads and aisles in your designs. It helps you to handle the most complex boundaries and obstructions with ease.


Energy modeling


    Calculate production, yield and production 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. 


Topography 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. 



Supporting software (NREL SAM, SunFig and PVBid)


PVBid


    SunDAT has the PVBid software integrated to account for the estimated costs of a system. Learn more about PVBid.


SunFig 


    For the financial estimation of a PV system, SunDAT applies the software SunFig. Learn more about SunFig.


NREL 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 SAM model can help you compare the economic potential of different system designs and evaluate their financial performance: Do you want to analyze your return on investment from a power purchase agreement (PPA) or a 3rd party leasing agreement? You can create your design in SunDAT and test the economics, then import your SunDAT files into other financial modeling programs for a closer look. Learn more about SAM
