The energetic utilization of solar photovoltaic systems for individuals: price changes in Hungary

The energy consumption has an important role in Human life and one of the biggest challenges is the continuously growing energy demand of the world. The aim of present study is to review the determination of the characteristics of the Hungarian energy supply, the introduction of renewable energy utilization and the economic determination of the return of crystalline solar systems in Hungary. This study shows us the effect of the changing investment cost to the payback period. This calculation can be important for a household to decide by or against a solar (PV) system. The main direction of our recent research is the utilization of photovoltaic (PV) solar energy. The studies were performed with crystalline solar systems. The research was carried out in solar-electric power plants extended from 3 kWp to 12 kWp. The study is about the investment of crystalline solar cell systems. The payback period is studied due to the help of static and dynamic indices
