In this study, feasibility analysis was done with a program that created a simulation model in the MATLAB GUI environment for the PV system installation in the production of electricity requirement of a house in Turkey conditions. The energy consumption is calculated through the data of the operating hours in a day and the number of running days in a year which entered by user. Once the panel and zone selection options have been specified, the program calculates the annual energy need for the house, the energy generated, the number of panels required to produce this energy, and the area required for system. Monthly energy distribution is shown graphically. Calculations are being revised for different panel number usage. In the economic analysis part, system cost, payback period and annual earnings are determined. PV system model, consumers will invest in renewable energy that will help to make the pre-feasibility and can be used as a decision-making mechanism.
