Can Ground-Mounted Solar Panels Benefit from East-West Orientation?

Maximizing Energy Production with East-West Orientation

Ground-mounted solar panels can be oriented east-west to take advantage of the sun’s path across the sky. By doing so, you can reduce shading and increase energy production. For example, in areas with trees or neighboring buildings, east-west orientation can help prevent morning and afternoon shading that would otherwise decrease energy output.

Design Considerations for East-West Orientation

When designing a ground-mounted solar array with east-west orientation, consider the following factors: land availability, roof height, and electrical connections. Typically, east-west arrays are most effective when the modules are spaced 12-18 inches apart to minimize shading. Additionally, you can use string inverters or individual string monitoring to ensure optimal performance and energy production.

Benefits of East-West Orientation in Off-Grid Systems

In off-grid systems, east-west orientation can be particularly beneficial due to the need for maximum energy production. By orienting solar panels east-west, you can increase energy production during both morning and afternoon hours, reducing the need for backup generators or batteries. This can lead to cost savings and increased system reliability. When designing an off-grid system with east-west orientation, consider using a string inverter with built-in monitoring to track energy production and optimize system performance.
