AB - In this study, the coldest days of 2022 in the Djelfa region, Algeria, were  determined using astronomical and climatic data. The timing of sunrise,  sunset, and duration of sunlight, as well as changes in solar radiation  intensity and air temperature, were analyzed. By converting solar radiation  into heat and solving differential equations, the study examined water exit  temperature, thermal energy, and total yield as outputs of a renewable  energy converter. The effect of different glass coverings on these outputs  was also investigated. The coldest day in 2022 was found to be the first day  of January, with nine hours and 43 minutes of sunlight, a maximum solar  radiation intensity of 670.34 MW/m², and a maximum air temperature of 16.9°C. The outputs of the solar center followed a parabolic pattern for the  first two parameters and increased over time for the remaining outputs,  regardless of the glass type. However, using glass with a high emission  coefficient, such as clear monochromatic glass, resulted in the highest  values for the outputs: 52.57°C, 7.5 kW, 162 MW, and 70.62%. By  understanding solar energy conversion and thermal behavior, the study  contributes to energy-efficient designs and renewable integration, aiding  in sustainable urban development. Findings can inform decision-makers in  optimizing material selection, promoting resilient infrastructure, and  advancing sustainable practices for a low-carbon future.
