Pathfinder Assistant Software
Version 5.0

PV and Thermal on one CD!

Solar Pathfinder Assistant Software (Version 5.0) used in conjunction with a Solar Pathfinder unit generates monthly sunpaths for each specific site latitude (instead of relying on the stock latitude band diagrams as in previous versions). Includes weather data for North America (Canada & USA), Central America, Europe, Southwest Pacific. All other sites will receive % of solar radiation only. Now, the SolarPathfinder Assistant V5 also calculates data for THERMAL heating systems (with the Thermal Module Add-On)! Now know exactly what size array you or your clients need when installing thermal systems for home or commercial heating.

Solar Pathfinder Assistant V5.0 +THERMAL

The SolarPathfinder Assistant thermal plug in allows you to choose from over 200 hot water collectors at the click of a button. Create a data-rich report that will give your clients the peace of mind they deserve.
