Any scientific analysis requires accurate input and careful calculations. The Solar Pathfinder and Assistant provides mathematical precision for accurate shading assessment (solar site analysis), eliminating gross errors in structure orientation, solar system sizing, PV/collector placement. The Solar Pathfinder Assistant software dovetails local weather data (using NREL/WMO) and site-specific shade analysis in a customizable report. Originally furnished for the ecological and photovoltaic applications, the Assistant software now services the growing thermal technologies (SPA4.0) (each sold separately). Create a data-rich report that will give your clients the peace of mind they deserve.
