Power output data calibration by comparing the experimental data to the computed data obtained from the simulation program TRNSYS . Power performance analyses were performed of PV modules facing south azimuth 0 depending on the different inclined angles of 0 10 30 50 70 and 90 . The data set consisted of the experimental data for 0 30 and 90 and the computed data for 10 50 and 70 . Figure 15 illustrates the monthly power output depending on the inclined angle ranging from 0 to 90 south azimuth 0 . PV modules that were tilted at an angle below 30 showed a relatively good power performance of over 6 kWh in the summer while those with an inclined angle above 50 demonstrated a power performance of less than 6 kWh. The most effective annual power output data of 977 kWh kWp was obtained at an inclined angle of 30 SLOPE_30 as shown in Figure 16. On the other hand the lowest annual power output of 357 kWh kWp was obtained from the PV module with a slope of 90 SLOPE_90 which was 37 of the annual power output of SLOPE_30. From Figure 16 it can be seen that the annual power output performance was effective in the order of SLOPE_10 954 kWh kWp SLOPE_0 890 kWh kWp SLOPE_50 860 kWh kWp and SLOPE_70 633 kWh kWp . The power generation performance depending on the angle of the azimuth was also estimated for PV modules with different inclined slopes as shown in Figure 17. Similarly a PV module inclined at an angle of 30 showed the most effective power output data for all directions in terms of azimuth angles and the lowest data was obtained from that with an inclined angle of 90 . For the PV module inclined at an angle of 30 the best power performance among the analyzed PV modules facing various directions was obtained for the PV module that was installed to the south azimuth 0 . It can be seen from Figure 17 that different azimuth angles affected the power performance of PV modules that is the power .
