A gap of approximately 10-15 cm is recommended to prevent shading issues between panels. Panel Tilt Angle: The tilt angle of the panels should be adjusted to capture the maximum solar radiation. This angle depends on the latitude of the installation site.
Additionally, there should be at least 12 inches of space between the two solar panels and the edge of the roof to abide by building codes and guarantee the safety of the solar array. The physical size of the solar panels usually determines the distance between solar panel brackets.
If the spacing between photovoltaic (PV) panels is inadequate, the front-row panels might cast shadows on the rear-row panels, leading to reduced power generation efficiency. Properly designed spacing is essential to ensure that each panel receives sufficient solar radiation.
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.
