Abstract

As the global push for more sustainable energy sources gains momentum, solar energy adoption is becoming increasingly significant. This research deals with the complex challenges that a special category of producers of electric energy from solar power, an individual producer - consumer encounters. More specifically, the research focuses on electric energy production-distribution-consumption data extraction, independently from the available data recorded and stored by the installed photovoltaic systems, and the suppliers of electric energy. The independent data extraction enables safe long-term data storage, and a possibility to perform different calculations enabling the optimization of the elements of the photovoltaic systems regarding their structure and capacity. The initial part of the research offers an overview of independent data extraction technology. Subsequently, a case study involving a producer-consumer household compares collected data with the photovoltaic system's output
