This study presents a comparative assessment of battery technologies used in solar photovoltaic (PV) energy storage systems, with the objective of identifying the most efficient and context-appropriate solutions for residential and small-scale applications. Data was collected through structured questionnaires administered to 71 respondents using purposive sampling on Lagos Mainland which includes solar engineers, energy practitioners, and end-users in Lagos State. The study employed descriptive and inferential statistics such as Chi-square tests, Analysis of Variance (ANOVA), correlation, and regression analyses using SPSS software. Findings revealed that lead-acid and lithium-ion batteries are the most used technologies. Despite widespread awareness of various battery types (98.6%), statistical analysis showed no significant difference in user-perceived performance across technologies (p > 0.05). Respondents’ perception rated lithium-ion batteries higher in efficiency, lifespan, and environmental friendliness, while lead-acid remained favored for affordability and accessibility. Key barriers to advanced battery adoption included high capital cost and import duties. Furthermore, 70.4% of respondents predicted that lithium-ion batteries will dominate by 2030, with “longer cycle life” identified as the top research priority for future development. The study recommends targeted incentives, local manufacturing support, and sustainable recycling programs to enhance battery adoption and environmental performance in Nigeria’s solar energy sector.
