## 5 Conclusions  
This study presents the design, simulation, and performance evaluation of a photovoltaic (PV) energy system tailored for the climatic conditions of Ankara, Turkey. The system integrates advanced MPPT methods, including ANN-based MPPT, RL-based MPPT, and a conventional MPPT method, to optimize energy generation and storage. The results demonstrate the significant advantages of advanced MPPT methods over conventional approaches in terms of energy efficiency, battery management, and load reliability. RL-based MPPT method emerged as the most effective approach, achieving the highest energy production and ensuring 100% load reliability throughout the year. Its ability to dynamically adapt to varying environmental conditions, such as changes in solar irradiance and temperature, highlights its potential for real-world applications. The ANN-based MPPT method also performed well, offering substantial efficiency gains and reliable battery management, though it exhibited minor limitations during transitional weather conditions. In contrast, the conventional MPPT method, while it is simple and widely used, showed significant performance gaps, particularly during winter months when solar energy availability is limited.  
The integration of a BESS further enhanced the system's reliability by mitigating the mismatch between energy generation and consumption. The advanced MPPT methods effectively managed the battery's SOC, minimizing energy losses and prolonging battery lifespan. These findings underscore the importance of combining advanced control algorithms with energy storage systems to maximize the efficiency and reliability of PV systems.  
Despite the promising results, several areas for improvement and future research have been identified. One of the key challenges in implementing advanced MPPT methods, such as RL and ANN, is their computational complexity and reliance on extensive training data. Future studies should focus on developing lightweight and computationally efficient algorithms that can be deployed on low-cost microcontrollers. Additionally, hybrid MPPT methods that combine the strengths of RL, ANN, and traditional approaches could be explored to further enhance system performance under diverse conditions. Another important area for future research is the integration of the PV system with emerging technologies, such as the Internet of Things (IoT) and smart grids. IoT-enabled sensors and communication networks can provide real-time environmental data, enabling more accurate and adaptive control of the system. Smart grid integration can facilitate energy trading and grid support services, further increasing the economic and environmental benefits of PV systems.  
In conclusion, this study highlights the potential of advanced MPPT methods, particularly RL and ANN, to revolutionize the performance of PV systems. By addressing the challenges and exploring the opportunities outlined above, future research can pave the way for more efficient, reliable, and sustainable renewable energy solutions.
