Recent literature suggests that peer effects are determined by the perceived credibility of one's active peer connections regarding PV and passive peer effects. Utilising data from a survey of German house owners who either own a PV or indicate purchase intention (N = 1,165), this paper explores the underlying mechanisms of active peer effects during different stages of PV adoption decision-making. Our findings suggest that the perceived credibility of peers on PV related issues is positively associated with the reported number of adopters in the decision-maker's peer group (passive peer effect) and also with the progress in the PV adoption decision process. Furthermore, we find a relationship between the perceived credibility of peers regarding PV and the reported influence strength of peer interactions throughout the decision-making processes of German householders, suggesting that subjective evaluations of peers play a role in active peer effects. Finally, we observe an association between the rate of self-initiated peer interactions about PV for respondents with a higher reported number of peers that have adopted PV, suggesting that passive effects (knowing peer PV adopters) play a role in initiating active peer interactions. These results are significant for all sub-groups, regardless of the decision progress. From a policy-making perspective, "bottom-up" efforts such as peer consultation and community-led outreach should be promoted in Germany to empower potential adopters.}, language = {en} } @article{SchellerGraupnerEdwardsetal., author = {Scheller, Fabian and Graupner, S{\"o}ren and Edwards, James and Johanning, Simon and Bergaentzl{\´e}, Claire and Bruckner, Thomas}, title = {Social Influence Throughout the Photovoltaic Adoption Process: Exploring the Impact of Stakeholder Perceptions}, series = {Energy RESEARCH LETTERS}, volume = {3}, journal = {Energy RESEARCH LETTERS}, number = {4}, issn = {2652-6514}, doi = {10.46557/001c.33903}, abstract = {This paper explores the role of social interactions in residential photovoltaic (PV) adoption. Our survey data from Germany indicate that residential PV decision makers are influenced primarily by stakeholders to whom they ascribe beneficial attributes. The data further show that key attributes vary along the decision making process: integrity and likeability demonstrate the strongest association with influence strength at the awareness stage, while availability and trustworthiness have the strongest association at the planning stage. The perception of the competence of the stakeholder is associated with greater influence across all stages.}, language = {en} }
