Why photovoltaic array installation should not be arranged too closely?

Too dense will affect power generation.

When the fixed photovoltaic array is installed on the roof, the distance between the front row and the back row must be considered to prevent the front row from blocking the back row and affecting the output power of the square array.

In the design process of power station, it is an important link for designers to avoid shadow occlusion between arrays. Generally, during the 6 hours from 9:00- 15:00 in winter to Sunday, the array spacing in the design should be considered not to be blocked by the previous photovoltaic array. But generally speaking, the actual layout is to reduce the area occupied by photovoltaic projects, and the arrays will be arranged more closely, causing shadows between the arrays.
