Optimization of PV system and technology in view of a load profile-case of public building in Turkey

ABSTRACT
The optimum sizing of PV technologies depends on certain variables such as the daily energy consumption of buildings and available solar potential of the location. The purpose of this paper is to define the optimum PV panel area with no battery system to supply the daytime electricity usage of a Vocational School in Şanlıurfa, Turkey. First, the maximum PV panel areas are found at the 100 % self-consumption for the Mono-Si, Multi-Si and CdTe PV technologies. Besides, for defining optimum installation powers, an economic analysis has been carried out. The seasonal performances of economical optimum capacities are investigated under the feed-in tariff scenario. At %100 self-consumption, the maximum PV panel areas are found 130 m2, 160 m2 and 170 m2 for Mono-Si, Multi-Si and CdTe respectively. The results show that the installation of Mono-Si (115 m2), Multi-Si (150 m2) and CdTe (210 m2) PV systems at 1.65, 1.75 and 2.3 times as the daily peak electricity consumption, is the most optimal selection according to economic indicators.
