Four rows of solar panels slant out from the roof

What is the minimum row spacing required for a solar panel?

Therefore, the minimum row spacing required for this system in Massachusetts, with a 6° tilt angle, is approximately 20 inches. This spacing will ensure that the panels do not shade each other during the winter solstice when the sun is at its lowest.

How to design a solar photovoltaic system for a flat roof?

When designing a solar photovoltaic (PV) system for flat roofs or ground-mounted applications, one of the most crucial aspects to consider is the spacing between rows of solar panels. Proper row spacing helps optimize energy production while minimizing shading, which can drastically affect system efficiency.

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.

Does Aurora solar calculate row spacing automatically?

While advanced design tools like Aurora Solar can calculate row spacing automatically, understanding the key variables and math behind this calculation allows solar professionals and homeowners to make more informed decisions. Why Is Row Spacing Important?
