Do tilt and azimuth angle changes affect photovoltaic energy production?

In this article the effect of tilt and azimuth angle changes of the photovoltaic system energy production is analyzed. These parameters have significant impact on the amount of solar radiation which hits on the photovoltaic panel surface and therefore also on the energy absorbed by the module surface.

What is the tilt angle of a photovoltaic system?

The tilt angle is the angle of the photovoltaic modules from the horizontal plane for a fixed (non-tracking) mounting [ 27, 54 ]. Generally, it is recommended that photovoltaic system should be installed with a tilt angle which is equal to the latitude of the site [ 55, 56 ].

Does the azimuth angle affect the performance of a PV installation?

The performance of a photovoltaic (PV) installation is affected by its tilt and azimuth angles, because these parameters change the amount of solar energy absorbed by the surface of the PV modules. Therefore, this paper demonstrates the impact of the azimuth angle on the energy production of PV installations.

Does tilt angle affect output power of a PV system?

The output power of the system was the highest for the tilt angle 30° and the optimal energy balance was detected for tilt angle from 15° to 30°. A very small difference of about 0.9% in energy production of PV system was identified for range (30–35°). If the tilt angle is greater than the 35°, the power decreases.

What is the tilt angle of a PV module?

The tilt angle of PV modules is 35°, which is in the literature [ 2] considered to be ideal for Central Europe. The azimuth orientation of the PV modules was South with the azimuth angle 0°. Efficiency of PV module is 14.8%. Power of one PV module is 240 Wp, so the total installed power is 103.68 kWp.

Which angle should a solar photovoltaic module be mounted?

However, to follow the classic theory of solar photovoltaic orientation, the module must be mounted facing south with an optimal tilt angle between 11.48° to 16.8°. In May and September, it is preferable to tilt the modules horizontally as all five modules with different tilt and orientation angles produced negative GRI values.
