Seasonal Analysis of Solar Energy and Hydrogen Production Potential in Adana
Öz
Photovoltaic (PV) panels play an important role in renewable energy production, particularly in regions with abundant sunlight, such as Turkey. Solar energy represents a strategic alternative for reducing Turkey's reliance on energy imports and lowering energy costs. This study focuses on evaluating the performance of a system comprising an 80W solar panel for electricity generation and hydrogen production via alkaline electrolysis, specifically designed for the Adana region. Simulations conducted in MATLAB/Simulink explored the effects of varying temperature and radiation levels on system performance. The findings reveal a direct correlation between power generation and solar radiation, with higher radiation levels leading to increased power output. However, elevated temperatures negatively impact the efficiency of the PV panel, resulting in reduced power generation.
In the experimental setup, graphite (G) and silver-copper-modified graphite (Ag-Cu/G) electrodes were utilized as cathodes, while a platinum electrode served as the anode. Operating voltages ranging from 2.5V to 3V were applied, demonstrating that hydrogen production increases with higher operating voltages. Surface characterization of the electrodes was conducted using SEM-EDX analysis. At 3V, after 15 minutes of operation, hydrogen volumes of 15 mL and 21.4 mL were obtained for G and Ag-Cu/G electrodes, respectively. Seasonal variations were also considered, highlighting that spring's frequent rainy and cloudy conditions limit sunlight availability, whereas the extended clear-sky durations of summer months offer a significant advantage for hydrogen production.
