Best Free Solar Design Software

Accurate estimation of solar energy potential is crucial in the pre-feasibility phase. Besides accurate results, it is also desired that the pre-feasibility study is done efficiently. Solargis prospecting tools, iMaps and pvPlanner, provide fast access to reliable solar yield estimates. The new Prospect tool further increases the accuracy of estimates and makes it easier to collaborate efficiently on the development of solar projects. Solargis data has the best accuracy and reliability amongst available solar databases. This has been confirmed by several independent studies. Solargis data has been validated at 1000+ locations globally. Validation statistics for 180+ non-confidential sites can be seen on our validation map. Popular simulation software such as PVsyst has advanced capabilities for system design and energy modeling. However, the default weather data in such tools is not the most reliable.

As little as five clicks and you can create a solar project packed with valuable information. Simple and instinctive drawing tools make accurate solar design accessible to any individual. While a single click can generate an entire layout if you dig deeper you can refine your solar design to create sophisticated designs.

Web-based PV design for utility-scale and commercial solar. Our innovative, patented system for determining layout optimizes Ground Coverage Ratio (GCR) and helps engineer enhanced yields on rough terrain. Handle complex boundaries and obstructions with ease. Automate workflows and increase the efficiency of your design process with SunDAT. This feature allows you to identify areas that are beyond a certain slope tolerance or flag areas within a solar array layout that need to be graded or avoided. You can also visualize heatmaps, export them to PVsyst, and perform pile length calculations. SunDAT enables you to export your project data in multiple formats like PDF, DXF and DAE. This allows your design to be imported to programs like AutoCAD and PVsyst for continued design and analysis. SunDAT Web software optimizes large-scale utility and commercial PV design. Whether you are designing a 150MW utility-scale ground mount or a 2 MW commercial rooftop solar system, SunDAT will do it.
