Sun Azimuth & Elevation Calculator

How to calculate sun position?

Solar position is derived from the observer's precise latitude and longitude on Earth, combined with the planet's orbital position relative to the sun at a specific point in time.

Formula: sin(h) = sin(φ)sin(δ) + cos(φ)cos(δ)cos(H)

Using the Sun Position calculator: an example

Consider an example for Los Angeles (Latitude 34.05) on the Summer Solstice, when the sun reaches its maximum northern declination.

Step-by-step calculation:

1. Determine the solar declination for the specific calendar date.
2. Calculate the local hour angle based on the solar time of day.
3. Solve the trigonometric equations to find the precise elevation and azimuth.

Frequently Asked Questions

What is solar noon?

Solar noon is the exact moment when the sun crosses the local meridian and reaches its highest point in the sky for that day. It often differs from 12:00 PM clock time due to factors like longitude and time zones.

How does latitude affect sun height?

As you move further from the equator toward higher latitudes, the sun's maximum elevation angle decreases. This results in lower paths through the sky and significantly longer shadows.
