Calculation rules for the installation span of photovoltaic panels

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:

How to calculate the angle of a photovoltaic panel?

Therefore, the angle can be calculated from the formula: Knowing the minimum angle of incidence of sunlight during the year, it is possible to determine the distance between successive rows of photovoltaic panels. The figure below shows the schematic diagram used to calculate the row spacing and the formula for the calculation:

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.

How do you calculate solar panel spacing?

Formula: Spacing = Height / tan (Solar Altitude). Solar altitude depends on latitude, tilt, and solar declination for the selected date. 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.
