Calculating Optimal Azimuth For Solar Panels In The Tropics

Azimuth is the array s east west orientation in degrees.

Calculating optimal azimuth for solar panels in the tropics.

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. In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres. Energy modelers also need to know the optimal tilt angle of a panel for calculating regional or global pv output in a given lo cation or worldwide. Let s start with two key terms.

On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The compass angle shows 180 for south 90 for east and 270 for west. Another issue for installers and modelers is whether 1 axis vertical tracked pv panels panels that face south or north and swivel vertically. Also the time zones are not explained and one would think could be automatically.

Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity. Optimum angle differs during winter months. Today we re going to explain how to mount your solar panels to get the most energy from them. For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun.

Welcome to another entry in our ongoing solar 101 series. Positive 90 degrees is facing due west negative 90 degrees is facing due east. The ideal angle for your solar panels can vary depending on your solar objectives.
