This Chapter presents a comprehensive literature review on key components of standalone solar PV systems, focusing on MPPT algorithms, DC–DC converters, and battery technologies. It explores various solar energy applications and the types of PV systems, followed by a detailed discussion of DC–DC converters and battery technologies commonly used in these systems. The chapter categorizes MPPT techniques into three groups: conventional methods, soft computing/artificial intelligence (AI) techniques, and hybrid MPPT algorithms. Conventional methods like P&O and INC are simple and cost-effective but have limited performance under rapidly changing environmental conditions. AI-based techniques improve performance but are complex and prone to failure in complex partial shading conditions. Hybrid methods combine the advantages of both but introduce challenges such as increased hardware complexity and slower convergence times. The chapter concludes by proposing novel MPPT approaches that aim to combine the simplicity of conventional methods with the effectiveness of advanced techniques, offering an optimal balance between simplicity and high tracking performance.
