6 FAQs about [The distance between the front and rear shading of the photovoltaic bracket]

How to choose a row spacing for a PV system?

In practical PV installations, the row spacing is mostly selected to avoid shading at noon in the winter solstice, and it is affected by the geographical location and the tilt angle of the PV modules. The relative row distance calculated by this simple thumb rule is 1.66 for the selected site and tilt angle.

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.

Can tilt angle and row spacing be optimized for fixed monofacial and bifacial PV arrays?

The tilt angle and row spacing are crucial parameters in the planning and design of Photovoltaic (PV) power plants. This study, aiming to minimize the Levelized Cost of Energy (LCOE) per unit land area, optimized the tilt angle and row spacing for fixed monofacial and bifacial PV arrays.

How many PV cells are under shading?

When the front row shadow is at node A1, the front and rear rows of the PV array are at the critical point of shading; when the front row shadow is at node B2, there are a total of four PV cells string units A1, A2, A3, and B1 under shading.

How to calculate photovoltaic shading?

Calculating photovoltaic shading is not a simple task as shadows shift position throughout the day and year due to the sun’s angle. Make sure to use a solar software that accurately assesses shading from obstacles, both nearby and distant, utilizing simple photographic surveys and creating a detailed solar diagram of the installation site.

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.
