Abstract

The energy is one of the most important needs of the humanity. One of its biggest challenge or danger is that the world's demand for energy continues to grow. The aim of present study is to review the introduction of solar energy utilization, the economic determination of the return of crystalline solar photovoltaic systems in Hungary, the electricity price reductions for individuals and the change in the payback period. The effect of the changing investment cost to the payback period based on the changes in electricity price reductions and in central bank interest rate is written in this study. An important question is for a household: decide by or against a solar (PV) system. The main direction of our recent research is the utilization of photovoltaic (PV) solar energy with crystalline solar systems. The research was carried out in solar-electric power plants extended from 1.5 kWp to 10 kWp. The calculation of payback time was performed by dynamic indices.
