Abstract
The challenge of providing reliable electricity during power interruptions, especially in rural and remote regions, has prompted the exploration of Hybrid Renewable Energy Systems (HRESs). This systematic review employs the PRISMA framework to conduct a comparative analysis of HRES configurations, specifically those integrating rooftop solar photovoltaic (PV), diesel generators (DGs), converters, and battery energy storage systems (BESSs). This review assesses the techno-economic performance of these systems in various countries, highlighting the cost efficiency, reliability, and environmental impact compared to traditional single-resource systems. The analysis reveals that HRESs offer significant advantages in managing energy supply during power interruptions, particularly in regions with high solar potential but unreliable grid access. A comparative analysis with other countries demonstrates that while HRES configurations are tailored to local conditions, the integration of solar PV with diesel generators is a consistently effective strategy across different contexts. This review provides essential insights for policymakers and stakeholders, facilitating the optimization of energy solutions tailored to regional needs.
