About the Solar Shadow Azimuth Calculator Online Free Tool

The Solar Shadow Azimuth Calculator Online Free Tool estimates solar altitude, solar azimuth, shadow bearing, and shadow length from latitude, day of year, solar time, and object height.

How to Use the Solar Shadow Azimuth Calculator Online

1. Enter latitude, day of year, and solar time.
2. Enter object height for the shadow-length estimate.
3. Run the calculator to review sun direction and shadow geometry.

Choosing Options Correctly

Use solar time, not necessarily clock time. The calculation is simplified and does not include time zones, equation of time, longitude correction, terrain, atmospheric effects, or local obstructions.

Common Use Cases

• Estimate shadow direction for site planning.
• Check rough solar geometry by season.
• Compare shadow length from different object heights.

Quick FAQ

What if the sun is below the horizon?
The tool reports the shadow length as unavailable.

Is azimuth measured from north?
Yes. Azimuth is measured clockwise from north.

Can I use any location and time?
Yes, if you enter the correct coordinates, date, time, and timezone context for the place being checked.

What affects real shadow length?
Local terrain, object shape, daylight saving time mistakes, horizon obstruction, and surface slope can change observed shadows.
