Quick Answer
Solar panels can be optimized for morning and evening sun by adjusting their tilt and orientation to capture the sun's rays during these periods. This can be achieved through a combination of techniques, including seasonal adjustments and using tracking systems.
Aligning with the Sun’s Path
To optimize solar panels for morning and evening sun, it’s essential to align them with the sun’s path. In the northern hemisphere, the sun rises in the east and sets in the west, which means solar panels should be oriented between 90° and 140° east of true south. For a standard 4x8 solar panel array, a tilt angle of 30° to 40° is recommended to maximize energy production during these periods.
Using Tracking Systems
Another effective way to optimize solar panels for morning and evening sun is by using tracking systems. These systems adjust the solar panel’s angle and orientation in real-time to follow the sun’s movement. A tracking system can increase energy production by up to 50% compared to static solar panels. For a residential solar panel installation, a dual-axis tracking system is recommended, which tracks the sun’s movement in both the azimuth and altitude axes.
Seasonal Adjustments
To further optimize solar panels for morning and evening sun, seasonal adjustments should be made. In the winter months, solar panels should be tilted at a steeper angle (45° to 50°) to capture the sun’s rays at a lower angle in the sky. In the summer months, the tilt angle can be reduced to 20° to 30° to avoid overheating and maximize energy production during peak sun hours. Using a solar panel tracker with a built-in seasonal adjustment feature can simplify this process and ensure optimal energy production throughout the year.
