Azimuthal Angle Of Solar Panels

The selection of azimuth and inclination angle of solar cell module is one of the most important factors in the design of solar photovoltaic system the so called azimuth generally refers to the east west north and south direction of the angle for the solar photovoltaic system the azimuth angle is 0 due south negative angle from south east to north and downward angle from south to north.

Azimuthal angle of solar panels.

Positive 90 degrees is facing due west negative 90 degrees is facing due east. Azimuth is measured in degrees clockwise from north. Cosine of solar zenith angle. This horizontal coordinate defines the sun s relative direction along the local horizon whereas the solar zenith angle or its complementary angle solar elevation defines the sun s apparent altitude.

Different references may however be found in the literature. Solar panels produce electricity when sunlight hits their surface and they produce the most energy when that sunlight is exactly perpendicular to the panel face. But that task is complicated by the fact that the sun moves across the sky throughout the day. The solar azimuth angle is the azimuth angle of the sun s position.

In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres. Az el both report dark after astronomical twilight. The azimuth and tilt confirmation of solar panel is the one of important factors in the design of solar pv system. Solar panels work best when they face directly into the sun.

The azimuth angle varies throughout the day as shown in the animation below. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. The compass angle shows 180 for south 90 for east and 270 for west. Elevation is measured in degrees up from the horizon.

The azimuth is the angle of easy west south and north. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. At the equinoxes the sun rises directly east and sets directly west regardless of the latitude thus making the azimuth angles 90 at sunrise and 270 at sunset. It also changes angle in the sky as the seasons change.

Angular displacement from south of the projection of beam radiation on the horizontal plane. In terms of solar pv system the due south of azimuth is 0 it is minus angle from south to east to north it is positive angle from south to west to north. The horizontal orientation of your panels in relation to the equator in this case.
