A bibliometric review of consumers' purchase behaviour for solar energy products

Purpose - This study aims to conduct the domain mapping of consumer behaviour research in the context of solar energy. The study can help in understanding the intellectual structure, evolution of keywords and key research producers (at the author, institutional and source level) related to the domain of solar energy consumer research. Design/methodology/approach - This study uses R-studios' bibliometrix package for analysing the bibliographical data collected from the Scopus database. Analysis has been conducted at the descriptive level (summary, author, institution and source) and analytical level (co-citation analysis, co-occurrence analysis, thematic maps and historiography). Findings - This study finds out the most relevant authors, institutions and sources using criteria such as production, citations and H-index. Relevant research clusters have been identified using the clustering of authors, co-citations and keywords. Thematic mapping has identified the basic and motor themes. Historical citation analysis shows the direct linkage of previous studies. Overall, this study reports the most relevant bibliometric indicators in the domain of solar energy consumer research. Practical implications - Identified patterns can help policymakers, business experts, social marketers and energy conservation organisations to study consumer behaviour. Social implications - Thiis bibliometric study can effectively assess sustainable development goals and suggest improved action plans. Originality/value - This study examined bibliometric analysis in solar energy products (SEPs), recognised varied domains of research work on consumers' intention to purchase solar household products and mapped them into six groups. This study provides an overview of 40years of research on consumer behaviour towards SEPs and discusses its findings to identify the research gap.
