Distance between photovoltaic panels

How far apart should solar panels be?

The spacing between solar panel rows depends on the sun's lowest altitude angle during your target period (often winter). A smaller altitude angle means longer shadows and therefore larger required spacing. Winter Solstice: Highest shading risk, requires maximum spacing. Equinox: Balanced all-year spacing recommendation.

How to determine the distance between photovoltaic panels?

Knowing the minimum angle of incidence of sunlight during the year, it is possible to determine the distance between successive rows of photovoltaic panels. 25 ° was taken as the value of the inclination of the supporting structure and the panel itself. Recommended values are in the range of 25 – 40 °. The height of the selected panel is 165 cm.

What is the minimum row spacing for solar panels?

Minimum row spacing for solar panels, critical to prevent shading, is typically 2–3 meters in mid-latitudes (e.g., 40°N), calculated using winter solstice sun angle to maintain 90%+ energy output, with fixed-tilt systems often at 1.5x panel height for optimal performance.

What is the row spacing of a photovoltaic array?

The row spacing of a photovoltaic array is the distance between the front and rear rows of solar panels. This spacing is calculated to ensure that the rear panels are not shaded by the front panels, maximizing the efficiency of the solar array. Let's assume the following values: Using the formula:
