In the contemporary era, characterized by an increasing emphasis on the need for environmentally friendly energy sources, solar energy emerges as a pivotal factor in the transformation of household energy systems. The integration of solar panels onto residential rooftops facilitates energy production, providing households with the opportunity to achieve greater independence. However, it is crucial to highlight that ensuring quality throughout the design of these systems is not merely a matter of efficiency but also compliance with a myriad of regulations, standards, and norms governing their application. The impact of standards and regulations on the process of designing solar power systems for households, and their adherence, ensures the safety, performance, and long-term sustainability of these systems. Focusing on the analysis of relevant standards in the field of designing solar installations for household self-consumption models, this thesis underscores key aspects of compliance and the implementation of prescribed guidelines as the foundation for achieving high quality in household-level solar power plants. The paper explores the laws, standards, and norms defining the process of designing solar power plants and their application to key elements. Through a specific case study, the investment cost is presented, along with an assessment of its profitability. Additionally, the paper includes the necessary documentation for the design, fabrication, and installation of solar power plants at the family-home level. It encompasses practical applications, challenges, and potential obstacles in the adoption of solar technologies in households. The procedure for grid connection of the power plant is described, along with the norm-defining conditions for electrical installations of photovoltaic systems.
