Geographical orientation - azimuth angle
Besides other the optimum geographical orientation of the PV modules is an important factor that determines the amonut of solar energy collected. A solar panel facing south (Azimuth 180°) promisses the highest energy yield.
To maximize the collection of the daily and seasonal solar energy possible, PV modules should be oriented geographically. In the northern hemisphere the optimum orientation for a PV module is true south (Azimuth 180° (in Europe 0°)). However, PV modules can face up to 45º east or west of true south without significantly decreasing their performance. Use the calculator for calculation azimuth and altitude.
