The analysis of different PV power systems for the determination of optimal PV panels and system installation - A case study in Kahramanmaras, Turkey

The next century will witness a breakthrough in terms of renewable energy sources, particularly solar energy and its derivatives. This renewable and enormous energy source offers a solution to the energy problem all over the world. One of the areas in which solar energy is used is the photovoltaic (PV) systems. The main element of this sector, however, is the pure silicon technology. Because, most efficient PV cells are made of silicon and its degree of purity is very important. The most commonly used types of these materials for PV energy conversion are thin Film, mono-crystalline and poly-crystalline silicon, which are also known as silicon modules or panels. However, performances of these modules vary by region. This study focuses on analyzing different three-type PV panels and determining the optimal panel type for Kahramanmaras with three separate PV systems, each 3-kWp and grid-connected. Besides, this study is the first research project to consider all aspects to determine optimal PV power system in the region. To this aim, three different PV systems consisting of thin film, mono-crystalline and poly-crystalline silicon panels were installed. The amount of energy generated by each system, cost analysis, annual incomes, breakeven points, installation area occupied by the system and total weights of each system are evaluated for each panel type used in the installed system and potential energy to be generated by solar energy in the region was considered. Following energy generation which lasted one year and at the end of the 30-year operation period, it is concluded that poly-crystalline silicon panels are the most optimal panel for the region because it yields the highest annual incomes and the shortest breakeven point for the investors. © 2015 Published by Elsevier Ltd
