sci.solar-angle-declination Calculator
Calculates solar declination angle δ = 23.45° × sin(360/365 × (284+n)) and solar elevation and azimuth at any location and time. Solar elevation at solar noon = 90° − latitude + declination — maximum elevation (≈90°) at the tropics at summer solstice; sunrise/sunset at elevation = 0°.
Inputs
Latitude Deg
Reference formula or conversion factor shown for context.
Day Of Year
Reference formula or conversion factor shown for context.
Hour Solar
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
solar altitude angle (°)
The computed angle in degrees or radians.
solar declination δ (°)
The value at the specified point or condition.
hour angle (°)
The computed angle in degrees or radians.
DNI factor (cos incidence)
A dimensionless multiplier applied in the calculation.
