Power supply for an island house from renewable energy sources

Renewable energy sources are increasingly used for electricity supply today, especially in remote locations where the grid is not available or due to environmental awareness. This paper analyses the cost-effectiveness of supplying households with electricity using renewable energy sources. Three variants were considered, a stand-alone solar power plant, a hybrid combination of a solar power plant and a petrol generator, and a hybrid combination of a solar power plant and a wind turbine. The goal is to find the most cost-effective solution for supplying households with electricity at a specific location on the island, taking into account the initial investment, but also the lifespan of photovoltaic modules, wind turbines, batteries and generators. Finally, with the presented calculation results, some recommendations are given as to which variant could be optimal depending on the facility using conditions.
