Panel spacing, or row spacing, refers to the distance between adjacent solar panels within a row. The optimal panel spacing depends on various factors, including panel dimensions, shading considerations, and system design. Striking the right balance between maximizing space utilization and minimizing shading is key to achieving peak performance.
The spacing between solar panel rows depends on the sun's lowest altitude angle during your target period (often winter). A smaller altitude angle means longer shadows and therefore larger required spacing. Winter Solstice: Highest shading risk, requires maximum spacing. Equinox: Balanced all-year spacing recommendation.
This approach suggests leaving a gap of at least two solar panels between rows. This spacing ensures ample airflow, reduces shading effects and enhances overall system performance. Implementing the two-solar-panel rule creates a well-ventilated and optimized system that minimizes shading between rows.
To calculate the row spacing between solar panels, you first need to determine the height difference from the back of the module to the ground. In this example, we use a Maysun Solar module with a width of 39.41 inches and an inclination angle of 15°. Here are the detailed calculation steps: Example: Rounded, the Height Difference is 10 inches.
