General Solar Position Calculations NOAA Global Monitoring Division First, the fractional year (γ) is calculated, in radians. γ = 2 365 ∗(day_of_year−1+ ℎ𝑜 −12 24) (For leap years, use 366 instead of 365 in the denominator.) From γ, we can estimate the equation of time (in minutes) and the solar declination angle (in radians).
Solar Panel Orientation Calculator
From the above table, we can see the tilt angle is highest in winter. That is because, in the winter months, the sun is near the horizon, thereby solar panels are positioned vertically. In the summertime, the sun is overhead at high altitudes, and panels are positioned ...
