Can You Create a Hybrid System with Different Panel Orientations?

Optimizing Panel Orientation

To create a hybrid system with different panel orientations, you can use multiple arrays with varying azimuth angles. A common approach is to have a secondary array with a fixed azimuth angle (usually east-west) to capture morning and evening solar radiation, while the primary array has a south-facing orientation for maximum midday production. This hybrid setup can increase overall energy production by up to 20% compared to a single, south-facing array.

Choosing the Right Azimuth Angles

When designing a hybrid system, the optimal azimuth angles depend on your location’s latitude and climate. For example, in the northern hemisphere, a south-facing array typically has an azimuth angle between 160° and 200°, while a secondary array with an east-west orientation can have an azimuth angle between 90° and 120°. To determine the best azimuth angles for your location, use online solar irradiance maps or consult with a solar expert.

Panel Orientation Considerations

When mixing different panel orientations in a hybrid system, consider the shading and wiring complexities. Ensure that the panels are installed to minimize shading between arrays and that the wiring is designed to accommodate the different orientations. Additionally, consider the panel’s tilt angles, which should be adjusted to optimize energy production based on the local solar radiation patterns.
