Sun Path & Solar Angles for Las Vegas, NV
Calculated solar-noon angles and a first-pass fixed-shading worksheet for Las Vegas, NV, using transparent solar geometry rather than an unexplained chart.
On this page
Last updated August 17, 2026 · Original calculation using latitude 36.1699° N and declinations +23.44°, 0°, and -23.44°. Formula: altitude = 90° - |latitude - declination|. Time zone: America/Los_Angeles. 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 Las Vegas, NV, using transparent solar geometry rather than an unexplained chart. A key reference is latitude: 36.1699° N; check the cited source, edition, units, and applicability before using it for design, compliance, procurement, or approval. Latitude is 36.1699° N; Las Vegas, NV. June solstice noon is 77.3°; south at solar noon. Equinox noon is 53.8°; 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.

Which solar conditions control the result?
| Date | Declination | Altitude | Projection / vertical shade distance |
|---|---|---|---|
| June solstice | +23.44° | 77.27° | 0.226 |
| Equinox | 0° | 53.83° | 0.731 |
| December solstice | -23.44° | 30.39° | 1.705 |
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.
Las Vegas, NV shading record
Record facade azimuth, window head and sill, overhang height, required shaded dates and hours, coordinates (36.1699° N), time zone (America/Los_Angeles), calculation method, surrounding obstructions, reviewer and date. Compare the full model against the three noon ratios above and retain screenshots of the critical summer and shoulder-season hours. Verify hourly positions with the NOAA Solar Calculator.
