Photovoltaic power plants (PPPs) or solar power plants are renewable energy sources that are gaining increasing importance today. Solar power plants transfer the generated electricity to the power system, enabling direct conversion of solar energy into electricity. The term thermal application refers to the direct use of solar energy for heating water, heating buildings or cooling a building. A more complex way of using solar energy (as opposed to passive solutions) is achieved by using thermal collectors. Photovoltaic cells are used as an independent or additional source of energy. As for the photovoltaic system, it can be connected to the power grid in two ways: by connecting to the power grid via a home installation or by directly connecting to the power grid. The disadvantages that arise when using solar energy are the inability to adequately store larger amounts of energy, there are oscillations in radiation intensity during the day and year, dependence on climatic conditions, lack of security of supply, radiation intensity does not match consumer demands, all in all, the production of electricity from solar sources is still not economical enough, therefore additional incentives are needed. Solar energy could become the main carrier of environmentally sustainable energy development in the near future as a highly acceptable renewable energy source. This is becoming the main reason for increased research into new procedures and processes for converting solar energy into electrical and thermal energy. Every energy plant, including solar power plants, changes the picture of the natural environment to a certain extent. In solar power plants, there is no combustion process, emissions of harmful substances, harmful impacts on air and water quality, soil degradation and noise impacts on the environment, so that if legal obligations are adhered to, the negative impacts of solar power plants will be minimal or negligible.
