Determining Module Inter-Row Spacing | Greentech Renewables

When designing a PV system that is tilted or ground mounted, determining the appropriate spacing between each row can be troublesome or a downright migraine in the making.

Solar PV Mounting Systems

The rows of panels must be spaced apart so that the row in front does not shade the row behind. This gap is roughly 500mm between the rear of one panel and front of another. Once in place, the ballast is then placed on the frame underneath the panels to hold it securely in place. The solar panels are then simply bolted to the triangular frame.

6 FAQs about [Photovoltaic panels front and rear rows blocked]

What are bifacial solar panels?

Bifacial solar modules are modules that generate energy on both their front and rear sides, based on solar cells with two active sides. While the energy production of traditional monofacial solar panels is relatively easy to forecast, bifacial panels provide a bit more of a challenge.

Do bifacial solar panels have a second rating?

Because this power rating considers only the front side of a solar panel, bifacial modules are also assigned a second rating for the electrical output of the module’s rear side.

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 are the shadows caused by the front row of PV arrays?

To facilitate analysis, we call the shadows caused by the front row of PV arrays as Front Array Inter-Row Shading (FAIRS), and the shadows caused by the sun that does not shine in front of the PV arrays is called Sun Position Inter-Row Shading (SPIRS).

How does row spacing affect PV power station performance?

Smaller row spacing can enhance the installed capacity of a PV power station within a limited area. However, it also induces a shading effect, thereby reducing the overall output performance of the PV power station. On the other hand, larger row spacing, while reducing losses from shading, leads to land waste and increased wiring costs .

Do PV power plants have horizontal or vertical rows?

There are two types of module layout in PV power plants, horizontal and vertical, and each has its own considerations regarding the use of horizontal or vertical rows depending on the situation. Which arrangement is more suitable for your home? What are horizontal and vertical rows of modules?
