A method to calculate array spacing and potential system size of photovoltaic arrays in urban environment using vector analysis.
We demonstrate that latitude is a stronger driver of inter-row energy yield shading losses than diffuse fraction, and present formulae for calculating the appropriate row spacing of a PV array for any latitude between 15–75°N. Our results provide updated guidelines for PV deployment system design that better suit the expanding PV sector.
This paper utilises vector analysis to develop a new method to calculate array spacing and potential system size for any combination of PV array and surface tilt and orientation. This approach is validated by comparing the vector results with ray-tracing shadow visualisations utilising the Ecotect software package.
New guidelines for inter-row spacing of PV power plants. A Canadian research group has applied new guidelines for ground coverage ratios to 31 locations in Mexico, the United States and Canada. It found the new formulae show that the factors affecting inter-row energy yield loss are highly dependent on latitude. July 6, 2023 Emiliano Bellini.

6 FAQs about [Regional photovoltaic panel array spacing]
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 do you calculate array spacing for a rack mounted PV array?
Within the existing literature, the simplest mathematical approach to calculate array spacing for a rack mounted PV array uses Eqs. (1), (2), (3) , for PV systems orientated towards the equator (see Fig. 1 ).
What are the guidelines for determining PV array layouts?
Traditional guidelines for determining PV array layouts were developed for monofacial fixed-tilt equator-facing systems at low-to-moderate latitudes, and no longer suit well the expanding PV market, which has been progressing toward bifacial technologies, tracked systems, higher latitudes, and land-constrained areas.
What is optimum spacing for bifacial PV arrays?
Latitude-based formulae given for optimum tracked, fixed-tilt, and vertical spacing. Optimum tilt of fixed-tilt arrays can vary from 7° above to 60° below latitude-tilt. Similar row spacing should be used for tracked and fixed-tilt PV arrays >55°N. Bifacial arrays need up to 0.03 lower GCR than monofacial, depending on bifaciality.
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.
Can a PV array be installed on a horizontal surface?
The standard mathematical approach used to calculate photovoltaic (PV) array spacing contains a number of assumptions that limits its use to PV arrays installed on horizontal surfaces.
