Sun Path & Solar Angles for Salt Lake City, UT
Calculated solar-noon angles and a first-pass fixed-shading worksheet for Salt Lake City, UT, using transparent solar geometry rather than an unexplained chart.
On this page
Last updated August 17, 2026 · Original calculation using latitude 40.7608° N and declinations +23.44°, 0°, and -23.44°. Formula: altitude = 90° - |latitude - declination|. Time zone: America/Denver. Verify occupied-hour positions with the NOAA Solar Calculator; values omit refraction, equation of time, terrain, obstructions, and facade azimuth.
Direct answer
Calculated solar-noon angles and a first-pass fixed-shading worksheet for Salt Lake City, UT, using transparent solar geometry rather than an unexplained chart. A key reference is latitude: 40.7608° N; check the cited source, edition, units, and applicability before using it for design, compliance, procurement, or approval. Latitude is 40.7608° N; Salt Lake City, UT. June solstice noon is 72.7°; south at solar noon. Equinox noon is 49.2°; geometric solar noon. Projection ratio = 1 / tan(solar altitude). Multiply the ratio by the vertical distance the noon shadow must cover. Use this only as a hand check before a full-year study. Read the values with the cited source, edition or observation period, units and applicability; replace illustrative inputs with current project evidence before design, procurement or approval use.
