Economic analysis of photovoltaic systems for household applications in Turkey

As a result of increasing demands from users, photovoltaic (PV) applications are currently in use in some practical applications such as solar watches and for lighting purposes, and since 1981 it has been used in buildings. While PV arrays are used to produce electricity by the solar power plants which are uncovered, they are first used on the roof of the buildings and then produced as roof plates for modern buildings. Research studies and findings on the effect of sun light amounts, shadow, the value of the thermal transitivity and damp-proofing on the PV arrays show that they are used effectively on the vertical covering of the buildings and pilot applications have been increasing since 1992. Most of the researches in nowadays are focusing on finding out economic PV arrays production methods. In this study, the electricity consumption of a house in Turkey is calculated in order to determine cost of electricity consumption depending on using machines and instruments. Then, the life cycle analysis of PV system is investigated. At the end of the study, a comparative analysis of electrical cost by PV arrays and operating costs are presented with the other energy sources referenced in literature. Turkish market values are used in calculations of the PV system.
