Know Exactly Where the Sun Will Be
The Solar Position Calculator determines the precise location of the sun in the sky for any moment in time. Whether you're installing solar panels, planning a photograph, or designing a building with optimal lighting, knowing the sun's altitude and azimuth is crucial for success.
What is Solar Position?
Solar position is described by two angles: altitude (elevation above the horizon, 0-90°) and azimuth (compass direction from north, 0-360°). These angles change throughout the day as Earth rotates and throughout the year as Earth orbits the Sun.
Solar Altitude Formula
sin(h) = sin(φ)sin(δ) + cos(φ)cos(δ)cos(H)Why Calculate Solar Position?

Frequently Asked Questions
Solar altitude is the angle of the sun above the horizon, measured in degrees. At 0° the sun is at the horizon, at 90° it's directly overhead (only possible near the equator).
