The minimum spacing between photovoltaic panels should be around 4 to 7 inches between each row12. Additionally, it is recommended to leave one to three feet of space between every second or third row2. To calculate the exact minimum distance, you can use the equation provided3..
There should be something like 4 to 7 inches of space between each row of solar panels, as the casing contracts and extends with the climate. This will help to ensure optimal efficiency and output..
The gap between solar panel rows should be around five to six inches, but it is also recommended that you leave one to three feet of space between every second or third row..
To solve for X (the minimum distance between the rows), use the equation below: X = L (cos (tilt)+ (sin (tilt) * tan (lat + 23.5+ (50% of elevation)))) Where lat= geographic latitude of your system. [pdf]

Roof The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle. If the panels are planned to be mounted before the construction of the roof, the roof can be designed accordingly by installing support brackets for. .
