Fig. 10 and Table 3 show the frequency distribution of the PV output power as a percentage of the daylight time of the year and the corresponding energy distribution. The daylight time corresponds to the total sum of hours in the year when the PV output power is non-zero, which is 4614.5 h in 2013. While the occurrence of high output power from PV panels is low, the energy delivered
by the panels at times of high output power is very high. PV Power >5 kW occur only 16% of the daylight time but delivers about 50% of annual PV energy.
