Renewable energy sources are becoming increasingly important due to rising energy consumption and environmental pollution caused by greenhouse gases. In the study, a system was designed to provide year-round air conditioning in a residential located in regions with low solar radiation. This design consists of a single-stage absorption cooling system to meet the cooling need in summer and a solar energy-supported natural gas combi boiler heating system to meet the heating need in winter. The designed system was subjected to a comprehensive analysis, taking into account the integration of four different collector types: flat plate collector, evacuated tube collector, compound parabolic collector and parabolic trough collector. A thermal energy storage unit is integrated into the system to increase its efficiency. In the study, the feasibility and efficiency of the solar energy system recommended for residences in low-radiation regions were investigated. Appropriate system conditions were determined by evaluating economic and environmental aspects. In the study, a maximum net present value (NPV) of 3.941.49 US$ and 4 % exercise efficiency were calculated for the system designed using ETC collectors at 80°C generator and 6°C evaporator temperature. At the same time, the hybrid system can prevent annual carbon dioxide emissions of 800.28 kg compared to coal-fired systems and 62.42 kg annually compared to natural gas systems. These results show that the designed system is economically feasible and contributes positively to environmental sustainability.
