  • Pathfinder

    US$299.00
    The Solar Pathfinder™ is non-electronic. Simple and straight-forward in its engineering, it requires no special skills or technical know-how. One simple tracing does the job and becomes the permanent record for the solar data. By combining the site-specific shading data of the Solar Pathfinder™ with the published global weather data, an accurate solar site analysis can be made. This insolation data, on an hourly and monthly basis can then be applied to architectural, engineering, solar, and ecological applications. All of this data is integrated in the Solar Pathfinder Assistant software, sold separately.
