Calculation of the spacing between photovoltaic panels

How do you calculate the distance between PV panels?

The separation between rows of PV panels must guarantee the non-superposition of shadows between the rows of panels during the winter or summer solstice months. We can calculate this distance whit this expression: d = ( h / tanH) · cosA Where: d is the minimum distance between panel lines.

How do I determine the correct row-to-row spacing for a solar system?

If your system consists of two or more rows of PV panels, you must make sure that each row of panels does not shade the row behind it. To determine the correct row-to-row spacing, refer to the figure above. There is no single correct answer since the solar elevation starts at zero in the morning and ends at zero in the evening.

Why do solar panels need a higher tilt angle & row spacing?

There are two reasons for this: first, when the module cost increases, it is uneconomical to install a larger capacity PV array on the same land area; Second, increasing the tilt angle and row spacing improves the PV array's efficiency in capturing solar irradiance, allowing for the optimal LCOE while arranging fewer PV modules.

Why is row spacing important for PV power plants?

The tilt angle and row spacing constitute two crucial parameters in the space design of PV power plants, exerting a significant influence on these facilities' performance and economic feasibility. Smaller row spacing can enhance the installed capacity of a PV power station within a limited area.

What is the optimal spacing for a PV array?

The difference in the height of the PV array leads to a large difference in the optimal spacing, ranging from 4.79 m to 9.37 m, but they are all much smaller than the corresponding standard row spacing.

What is a vector analysis method for row spacing in PV systems?

Reference developed a vector analysis method for the row spacing in PV systems on horizontal and non-horizontal planes. Shading on the PV modules reduces the incident solar radiation and hence reduces the electric output energy of the system.
