The distance between the front and back of the photovoltaic panel array

The row spacing of a photovoltaic array is the distance between the front and rear rows of solar panels.

The row spacing of a photovoltaic array is the distance between the front and rear rows of solar panels. This spacing is calculated to ensure that the rear panels are not shaded by the front panels, maximizing the efficiency of the solar array.

PV Row to Row Spacing. 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.

The azimuth correction angle is the horizontal angle between true south and the orientation of the solar array. This angle affects how much sunlight each row receives and helps ensure minimal shading throughout the day.

In buildings oriented with their ridges running east-west (i.e., north-facing slopes), it is essential to calculate the height difference between the front and back rows of PV arrays. The slope coefficient ( i ) is defined as the height difference divided by the horizontal distance between the highest and lowest points of the roof.

6 FAQs about [The distance between the front and back of the photovoltaic panel array]

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.

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.

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 the optimal tilt angle of photovoltaic solar panels?

The optimal tilt angle of photovoltaic solar panels is that the surface of the solar panel faces the Sun perpendicularly. However, the angle of incidence of solar radiation varies during the day and during different times of the year.

Why should solar panels be separated between rows?

In this case, the type of solar panels in our solar power system should be more robust to resist mechanical impacts due to the weather conditions. 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.

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.
