Solar Pathfinder Tool (for sale)

The Solar Pathfinder™ is a non-electronic tool that helps determine the amount of usable sun on a aprticualr site. 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. When properly cared for, the unit will give the user years of accurate site analysis. The Solar Pathfinder™ uses a highly polished, transparent, convex plastic dome to give a panoramic view of the entire site. All the trees, buildings or other obstacles to the sun are plainly visible as reflections on the surface of the dome. The sunpath diagram can be seen through the transparent dome at the same time. This diagram is latitude specific [the further away from the equator, the lower the sun will be in the sky, thereby making the sunpath further from the center of the unit] and shows the sun’s average path for each month. The rays of the diagram depict solar time. The diagram itself is therefore calibrated to give solar insolation data for all the hours of the day and all the days of the year. The diagram is also specific to the application: “South-facing” (for Northern hemisphere) or “vertical” is for applications of 20-90 degrees tilt – usually solar; “Horizontal” is for applications of 0-20 degrees tilt – usually ecological (For the flexibility of calculating radiation of any azimuth and any tilt angle, use our Solar Pathfinder Assistant software in addition to the Solar Pathfinder).
