The exact photo voltaic angle at dawn is, after all, extremely depending on the precise time and your location. Nonetheless, on June twentieth, two thousand twenty-five, we are able to estimate the solar’s altitude to be fairly low, in all probability round ten levels above the horizon, and its azimuth will likely be east of north, someplace close to sixty levels.
Noon’s Peak
Because the day continues, the solar will start its journey throughout the sky. At noon, or photo voltaic midday, the solar will attain its highest level within the sky. On June twentieth in Flagstaff, we anticipate that photo voltaic midday will happen round noon. The photo voltaic angle at this level would be the highest of the day, providing probably the most direct daylight. Primarily based on the time of the 12 months and Flagstaff’s latitude, the solar will obtain its peak photo voltaic angle at noon. This can affect the diploma of sunshine a constructing receives.
Afternoon Descent
Within the afternoon, because the solar progresses in direction of the western horizon, the photo voltaic angle will start to say no. At late afternoon, round 4 o’clock within the afternoon, the solar will likely be significantly decrease within the sky, casting longer shadows and a extra diffuse mild. This discount within the photo voltaic angle will imply that much less direct daylight hits surfaces, which is able to lower the quantity of warmth absorbed by objects and other people on the bottom.
