The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter, and subtracting 15 degrees from your latitude during summer.

Key takeawaysThe optimal solar panel angle is typically equal to your latitude for maximum year-round energy production.Seasonal adjustments can boost efficiency: decrease the angle by 15° in summer and increase it by 15° in winter.Factors like roof pitch, shading, and time of day can affect your panel's performance.
