6 FAQs about [Standard specification requirements for photovoltaic panel row 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.

What is the minimum array area requirement for a solar PV inverter?

Although the RERH specification does not set a minimum array area requirement, builders should minimally specify an area of 50 square feet in order to operate the smallest grid-tied solar PV inverters on the market.

How do I determine the correct row-to-row spacing for a solar system?

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. There is no single correct answer since the solar elevation starts at zero in the morning and ends at zero in the evening.

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.

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 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.
