In this article you will earn how to calculate the inter-row spacing for tilted or ground mounted PV systems. You may avoid potential shading issues and have the ability to increase the system size.
In this article you will earn how to calculate the inter-row spacing for tilted or ground mounted PV systems. You may avoid potential shading issues and have the ability to increase the system size.
Using our 3D view-factor PV system model, DUET, we provide formulae for ground coverage ratios (GCRs –i.e., the ratio between PV collector length and row pitch) providing 5%, 10%, and 15% shading loss as a function of mounting type and module type (bifacial vs monofacial) between 17-75°N.
Taking into account the shading between rows created by the tilt of the panels, fixed structures can reduce the pitch distance by installing more rows and increasing the amount of peak power and total energy generated. Fixed panel designs can be tailored to fit the highest quantity of panels at each site.
In the study “Optimal ground coverage ratios for tracked, fixed-tilt, and vertical photovoltaic systems for latitudes up to 75°N,” published in Solar Energy, the scientists said the new .
Here we see the Preset Library field which contains all the presets we created just before for this specific DWG file. From here you can select which of the available presets we should use when creating new PV areas. You can select one or multiple presets that you would like to utilize, as long as they have matching row counts, vertical gap size, and tilt angles.

6 FAQs about [Fixed gap of photovoltaic panels]
How to determine the effective row spacing between solar panels?
The effective row spacing between the panels is decided by, The Tilt angle of a panel varies with the location of the roof and is the most significant factor in deciding the row spacing. It is the angle between the solar panel and the roof base. The shadow pattern is derived from the tilt as well as the height of the panel.
Why should you choose a fixed panel solar system?
Fixed panel designs can be tailored to fit the highest quantity of panels at each site. As more solar PV is installed and the power generated is injected into the grid in the central hours of the day, it causes the market price of energy to fall sharply, cannibalizing its own profit.
Why do tilted panels have a gap between them?
These tilted panels, in turn, cast shadows on the successive panels behind them, necessitating a defined gap between them to reduce the losses that may incur due to shadow. Therefore, an optimum spacing between the panel rows needs to be decided.
Why do PV panels use phase change materials?
The use of Phase Change materials allows absorbing excessive thermal energy in PV panels, contributing to regulating their temperature and improving conversion performance (Ma et al., 2019). The advantage of using PCMs is that a great amount of heat can be dissipated from the PV module via the exploration of the PCM's latent energy (Ali, 2020).
What are solar photovoltaic design guidelines?
In addition to the IRC and IBC, the Structural Engineers Association of California (SEAOC) has published solar photovoltaic (PV) design guidelines, which provide specific recommendations for solar array installations on low-slope roofs 3.
How does a fixed-tilt PV system work?
Rather than using a tracker structure that adjusts the angle of PV panels to follow the sun during the day, a fixed-tilt structure angles panels towards the equator, so the angle depends on the latitude of the site. Panels are tilted towards the south in the northern hemisphere and towards the north in the southern hemisphere.
