Quick Answer
The angle of sunlight varies by season, with solar panels in the northern hemisphere receiving more direct sunlight during summer months when the sun is at its highest elevation and less direct sunlight during winter months when the sun is at its lowest elevation.
Solar Panel Mounting and Seasonal Angle Adjustments
When it comes to solar panels mounted on the ground, the seasonal variation in sunlight angle can be significant. To maximize energy production, ground-mounted solar panels should be tilted at an angle that tracks the sun’s movement throughout the year. A tilt angle of 30-40 degrees is commonly recommended for the northern hemisphere to ensure optimal energy production.
Calculating Optimal Tilt Angle
To determine the optimal tilt angle for your solar panel ground mount, you can use the latitude of your location. For instance, if you’re located at 40 degrees north latitude, a tilt angle of 30-40 degrees would be suitable. However, if you’re located at 60 degrees north latitude, a tilt angle of 50-60 degrees would be more suitable. You can also use online tools or consult with a solar panel expert to determine the optimal tilt angle for your specific location.
Tracking the Sun’s Movement
To further maximize energy production, you can consider using a solar tracker to track the sun’s movement throughout the day. Solar trackers use a motorized system to move the solar panels to follow the sun’s path, ensuring that the panels receive the maximum amount of direct sunlight. This can result in an additional 10-20% increase in energy production compared to fixed-tilt solar panels.
