4 FAQs about How to use the photovoltaic panel gap-leaving tool

Can a photovoltaic system reduce the distance between solar panels?

Solutions to reduce the distance between the rows are acceptable, but it has a direct impact on energy yields, especially in the winter months, as well as on the lifetime of photovoltaic cells from the panels of the lowest rows of the installation.

Why do solar panels need to be aligned correctly?

Correct azimuth alignment reduces shading and ensures each row gets sunlight for the maximum number of hours per day. To take the guesswork out, we've built a Solar Panel Row Spacing Calculator. Enter your site's latitude, tilt, and azimuth, and it will calculate the minimum spacing needed to avoid shading at the winter solstice.

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:
