Azimuthal Angle Of Solar Panels

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.

Azimuthal angle of solar panels. 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. Different references may however be found in the literature. 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. The solar azimuth angle is the azimuth angle of the sun s position.

The compass angle shows 180 for south 90 for east and 270 for west. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. 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. Az el both report dark after astronomical twilight.

Cosine of solar zenith angle. Solar panels work best when they face directly into the sun. Solar azimuth angle a. The azimuth and tilt confirmation of solar panel is the one of important factors in the design of solar pv system.

The azimuth is the angle of easy west south and north. Positive 90 degrees is facing due west negative 90 degrees is facing due east. Angular displacement from south of the projection of beam radiation on the horizontal plane. Elevation is measured in degrees up from the horizon.

Azimuth is measured in degrees clockwise from north. 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. It also changes angle in the sky as the seasons change. The horizontal orientation of your panels in relation to the equator in this case.

Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light. In general a 0 equals south a 0 is east and a 0 is west. In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres.
