Nowadays, ever-increasing energy costs and an emphasis on environmental protection are the main reasons why many households are opting for photovoltaic systems.
Mr. Novák from Veľká Ida near Košice was looking for a way to reduce his annual electricity costs, which amounted to approximately €1,280 with a consumption of around 8-9 MWh. He decided to take advantage of the benefits of solar energy and contacted us to propose a solution.
Based on Mr. Novák's requirements, we designed the hybrid system ANTIK DOMÁCNOSŤ STRED with an output of 7.65 kWp. The system includes a 10 kW three-phase hybrid inverter and 18 full black panels with an output of 425 Wp. The total price of the system, including installation and after deducting the subsidy, was €4,607 (without subsidy: €8,632).
After a year of using the photovoltaic system, Mr. Novák found that his system produced a total of 8.38 MWh of energy. This production was divided as follows:
Surpluses were used for water heating, pool heating, solar air conditioning and electric vehicle charging, or sent to a virtual battery for later use. In this way, all the energy produced was used to the maximum, contributing to further savings.
The return on the system was very favorable for Mr. Novák thanks to a state subsidy of €4,025. The current return on his investment figures are:
This will save Mr. Novák at least €980 on electricity bills annually.
Investing in a photovoltaic system is not just about immediate savings. For Mr. Novák, it also means long-term energy self-sufficiency and protection against rising energy prices. In addition, it contributes to reducing the carbon footprint, which has a positive impact on the environment. Mr. Novák is now less dependent on external energy suppliers and has more control over his electricity costs.
