Economic Feasibility and Technical Assessment of Solar Photovoltaic System Implementation for District Heating Infrastructure in Maribor

Abstract

This study examines the economic feasibility and technical specifications for implementing a modular photovoltaic solar energy system at the Maribor district heating infrastructure, including both rooftop installations and parking area facilities. The primary objective is to enhance the organization's energy independence, reduce electricity procurement costs, and accelerate the transition to sustainable renewable energy use. By deploying solar photovoltaic technology, this research aims to optimize energy generation while ensuring financial viability and environmental sustainability throughout the project lifecycle.
Various design configurations and deployment strategies were evaluated using the PV*Sol simulation platform, which enables detailed modeling and performance assessment of photovoltaic energy systems. The investigation focused on identifying the most economically advantageous configuration by analyzing factors such as power generation capacity, initial investment requirements, and system operational efficiency. A comparative analysis of different modular system architectures was conducted to determine the optimal approach for system expandability and peak performance.
The study also addresses the legal and regulatory framework relevant to solar power plant development and deployment, including compliance with national and European Union energy directives, electrical grid interconnection requirements, and available subsidy mechanisms.
The analysis determined the project's long-term financial sustainability, identified potential implementation challenges and risk factors, and recommended the most cost-effective and environmentally responsible deployment strategy.
