Good design and sizing of photovoltaic (PV) systems is very important in order to effectively harvest energy and minimize the investment cost. The optimum tilt and azimuth angles at which a PV system should be installed are often debated. This paper evaluates the tradeoff between annual energy generation and payback period reduction through the ana...

... monitored data in one-minute timesteps obtained from the irradiance sensors shown in Fig. 1b, were used for the analysis of the solar potential in different orientations and tilt-angles. Fig. 2 shows the hourly average data of the measured irradiance profiles for summer and winter days. It can be seen that the highest irradiance values in winter are obtained for the tilt-angle 60° South. However, in summer, the tilt-angle with higher solar intensities is 30° South. Tilt-angles of 30° and 60° for East and West orientations ...
