As the global shift toward cleaner and more sustainable energy sources continues, the adoption of solar energy is becoming increasingly prominent. However, the Republic of Serbia, like many other nations, confronts unique obstacles when striving to unlock the full potential of solar energy, particularly within the domain of individual producers–consumers. This research explores the intricate challenges that an individual producer–consumer encounter in Serbia as they endeavor to embrace solar power as a renewable energy source. An insight into the distinctive landscape for individual producer–consumer will be presented, encompassing the current regulatory framework. Through a case study that includes a producer–consumer household, experiences of using photovoltaic solar energy system in Serbia will be discussed, including the economic viability by evaluating the financial aspects of solar power investments, including initial costs and the return on investment. Ultimately, the main objective of this research is to provide valuable insights into the challenges confronted by individual producers–consumers in Serbia regarding the adoption of solar energy. It aims to inspire constructive discussions and facilitate the development of solutions for a sustainable energy future in the country.
