Can I Combine South and East Orientations for Better Output?

Understanding Solar Panel Orientation

When designing a solar panel array, orientation is a crucial factor in determining its efficiency. In general, south orientation is considered ideal for maximum sunlight exposure, as it receives direct sunlight for most of the day. However, in areas with significant morning and afternoon sunlight, an east orientation can also be beneficial.

Combining South and East Orientations

To combine south and east orientations, a common approach is to use a split array configuration. For example, you can set up a south-facing array that accounts for 60-70% of the total system capacity, and an east-facing array that makes up the remaining 30-40%. This configuration allows you to take advantage of the morning sunlight while still benefiting from the afternoon sun.

Practical Considerations

When implementing a combined south and east orientation, it’s essential to consider the specific site conditions and solar panel specifications. Factors such as the latitude, climate, and shading issues should be taken into account to ensure optimal performance. Additionally, the array configuration and tilt angle should be adjusted accordingly to maximize energy production. A general rule of thumb is to tilt the south-facing array at an angle of 30-40 degrees, and the east-facing array at a slightly lower angle (20-30 degrees) to account for the morning sun.
