Why do PV collector rows have smaller inter-row spacing?

... For limited land (e.g., rooftops), the PV collector rows are usually dense-deployed, with smaller inter-row spacing, as the objective of the PV system design is to meet some desired electric output power as an example, thus settling for a larger percentage of shading losses.

How to choose the optimal inter-row spacing for a PV system?

Beforehand, a distinction ought to be made about the dimensions of the land on which the PV system is deployed: limited (e.g. rooftops) and unlimited land. Taking these factors into consideration, the optimal inter-row spacing may be derived from the solution of a “constraint optimization problem”, that formulates the design of a PV system.

How does array spacing affect the performance of grid-connected photovoltaic systems?

The performance and economics of grid-connected photovoltaic (PV) systems are affected by the array spacing. Increasing the array spacing implies reducing the impact of shading, but at the same time, it increases the land purchase/preparation costs and the wiring costs.

Why is inter-row spacing important in photovoltaic systems?

Inter-row-spacing plays a significant role in the performance and economics of photovoltaic (PV) systems. The performance and economics are expressed by the amount of the energy generated along the life time of the system and the payback time.

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.

How does inter-row spacing affect solar energy loss?

The losses of the solar incident energy (radiation losses) of the PV system stem from the inter-row shading and masking (part of the sky obscured by rows in front), and are affected by the inter-row spacing.
