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?

Solar Energy Systems

Optimize solar panel tilt and orientation for maximum energy capture.

Architecture & Design

Plan window placement, shading, and passive solar heating.

Photography

Plan golden hour shots and predict lighting conditions.

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).
