The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter, and subtracting 15 degrees from your latitude during summer..
To pinpoint the declination angle on any day of the year, we use this formula: δ = 23.45 × sin ( 360 / 365 × (d+10)).
This angle is calculated as (34 * 0.9) – 23.5 = 7.1° in the case above. During the spring and autumn, the best tilt angles are achieved by subtracting 2.5° from the latitude..
Tilt Angle (in degrees) = Latitude + Solar Declination + Angle of Incidence Here’s what each component means: Latitude: This represents the geographical location of the solar panel installation site. [pdf]
