The Solar Pathfinder ST SPF-01 is a simple, non-electronic instrument used for solar site analysis and shading assessment. It helps solar professionals, engineers, architects, researchers, and environmental consultants identify how trees, buildings, and other nearby obstructions may affect sunlight availability at a selected location.
The instrument uses a highly polished, transparent convex dome that reflects the surrounding environment while displaying a solar path diagram beneath it. Users can trace shading patterns for different months and times of the day, creating a permanent record of the site conditions. Since it works on a reflective principle, it can be used in cloudy or clear weather and does not depend on the actual position of the sun during the survey.
Accurate shading analysis is important for photovoltaic system sizing, solar panel placement, collector orientation, building design, and environmental studies. When site-specific shading data from the Solar Pathfinder is combined with published weather and solar radiation information, users can estimate hourly and monthly solar access more reliably. The ST SPF-01 offers a practical and durable solution for reducing design errors and evaluating the suitability of a site before solar installation.
