Active peer effects in residential photovoltaic adoption: evidence on impact drivers among potential and current adopters in Germany.

摘要: While the importance of peer influences has been demonstrated in several studies, little is known about underlying mechanisms active effects residential photovoltaic (PV) diffusion. Empirical evidence indicates that impacts inter-subjective exchanges are dependent on subjective mutual evaluation interlocutors. This paper aims to quantify, how evaluations peers affect across different stages PV adoption decision-making. The findings a survey among potential and current adopters Germany(N=1,165)confirm two hypotheses. First, play role adoption: number decision-maker's social circle positive effect belief their network supports adoption; ascription credibility PV-related topics peers; interest actively seeking information from all decision-making stages. Second, there correlation between perceived attributes given reported influence said within process, suggesting decision-makers' an important effects. Decision-makers significantly more likely engage be influenced by interactions with who they perceive as competent, trustworthy, likeable. In contrast, such physical closeness availability have less significant effect. From policymaking perspective, this study suggests density quality connections empower adopters. Accordingly, consultation community-led outreach initiatives should promoted accelerate adoption.
