Abstract Buildings contribute significantly to global energy consumption, positioning them as pivotal to achieving global sustainability and climate goals. Although renewable energy technologies hold significant transformative potential, their integration into building systems is hindered by fragmented technological, economic, policy, and social dimensions. This systematic review addresses the existing lack of holistic synthesis by examining peer-reviewed studies published from 2019 to the second quarter (Q2) of 2025. Methodologically, the study adheres to the PRISMA 2020 framework to ensure transparency and replicability and employs bibliometric analysis to map thematic clusters across disciplines. Five major themes emerged from the synthesis: photovoltaic integration, retrofitting strategies, governance frameworks, smart grid applications, and stakeholder acceptance. Analysis highlights notable regional disparities, with Western Europe and East Asia demonstrating higher integration rates due to robust policy structures and established financial incentives. Conversely, regions like Sub-Saharan Africa and Latin America continue to experience significant barriers linked to financing constraints, regulatory fragmentation, and infrastructural limitations. Community-led microgrid initiatives in Kenya and Brazil emerge as exemplars of successful context-sensitive, low-cost renewable integration, emphasizing the value of inclusive governance and localized solutions. The review reco...
