4 FAQs about Principle of photovoltaic panel column positioning

What is solar panel positioning?

Before diving into specific recommendations, it's essential to understand the key concepts that govern solar panel positioning. Orientation refers to the cardinal direction your solar panels face (north, south, east, or west), also known as the azimuth angle.

What is solar panel orientation?

Solar Panel Orientation refers to our azimuth setting. Most of the energy coming from the sun arrives in straight line. A solar panel or solar array will capture more energy if it is facing directly at the sun, perpendicular to the straight line between the position of the panels installation and the sun.

Why do solar panels need to be vertical?

For example, when the sun is lower in the sky during the winter months the solar panels orientation needs to be more vertical as the solar radiation passes through more atmosphere to reach the solar panel and therefore its intensity is reduced by the scattering and absorption effect of atmosphere and clouds.

How do you calculate solar panel orientation?

The position of the sun in the sky can be plotted using two angles, azimuth and zenith and the angle of the solar panel orientation relies upon these two values. Azimuth – This is the compass angle of the sun as it moves through the sky from East to West over the course of the day. Generally, azimuth is calculated as an angle from true south.
