How Does Latitude Influence the Optimal Solar Panel Angle?

Latitude influences the optimal solar panel angle by determining the angle at which sunlight hits the Earth. Different latitudes receive varying amounts of solar energy throughout the year due to the tilt of the Earth’s axis.

At lower latitudes, near the equator, the sun is positioned higher in the sky. Therefore, solar panels should be tilted at a smaller angle to capture sunlight effectively.

At higher latitudes, closer to the poles, the sun remains lower in the sky. Hence, solar panels need a steeper angle to maximize exposure to sunlight, especially during winter months.

To find the optimal angle for solar panels, one often uses the formula: optimal angle = latitude × 0.87 + seasonal adjustments. This formula accounts for the latitude while considering seasonal variations.

In summary, latitude directly affects the optimal tilt of solar panels, ensuring maximum solar energy absorption based on the sun’s position in different regions.
