Sun Angle Calculator

Calculate the sun's azimuth and elevation angles for any location, date, and time of day.

How It Works

Enter your latitude, longitude, date, and time. The calculator computes solar declination and hour angle to find the sun's elevation above the horizon and compass azimuth.

Formula

Elevation = arcsin(sin(lat)xsin(decl)+cos(lat)xcos(decl)xcos(ha)) | Azimuth from north

Frequently Asked Questions

What is solar azimuth?

Solar azimuth is the compass direction of the sun measured from north (0 degrees) clockwise through east (90), south (180), and west (270).

How does sun angle affect solar panels?

Solar panels generate maximum power when perpendicular to the sun. Knowing the sun's angle helps optimize panel tilt and orientation.
