Solar energy is one of the most prominent and widely accessible renewable sources. Within this domain solar photovoltaics (PV) have been recognized an effective means converting solar energy into electricity. The environmental and economic benefits of PV have gained considerable scholarly attention, but their social impacts remain fragmented and less systematically addressed. This study conducted a focused literature review on social impacts of PV technology at building scale to identify underexplored social dimensions. Using thematic analysis, the review synthesizes reported impacts into ten clusters covering decent work and labour standards, employment and economic development, community and social integration, equity, poverty and accessibility, governance, policy and regulation, health, safety and well-being, resource use and environmental-social linkages, political impacts, public awareness, acceptance and perceptions, education, skills development and social welfare. Each impact cluster includes impacts, sub-impacts reflecting both qualitative and quantitative evaluations and is mapped against six major stakeholder groups: workers, local communities, society, consumers, governance and value chain actors. The findings reveal that most of the studies prioritize conventional impacts such as employment opportunities, occupational health and safety and energy accessibility. However, a small number of studies address additional social impacts that remain underdeveloped, including community engagement and participation consumer and public perception and governance, policy and regulation impacts. These impacts are conceptually recognised but rarely measured into the social impact assessment frameworks. Similarly, the worker stakeholder group received the most detailed attention, with many sub-impacts quantitatively assessed, whereas other groups such as local communities were frequently cited but rarely subjected to detailed evaluation. These findings highlight a critical gap in comprehensive social assessment of PV. By systematically mapping impacts, sub-impacts, and stakeholders, this study proposes a conceptual framework of underexplored social dimensions of PV deployment.
