Community shared solar (CSS) program has great potentials in contributing to the complete decarbonization of the power sectors worldwide. Few research have focused on its potential diffusion from the user perspective. This paper fills the gap by conducting a survey-based unlabeled choice experiment in the Guangdong Province, China to investigate the determinants of potential users' willingness to participate in CSS programs. We analyzed the survey data using a random parameter logit model. Our results show that users are more likely to participate in CSS programs with lower upfront payment, trialability, shorter payback period, a public utility as provider and larger impact on climate change mitigation. However, they are likely to accept longer payback period in CSS programs with higher participation rate because of the potential benefit from interpersonal communication. Users' previous knowledge of CSS programs and income will also increase their willingness to participate in CSS programs with higher upfront payment. Our results provide important implications for designing policies and business models to promote the distributive renewable energy in China. • Community shared solar is widely accepted among surveyed individuals in our choice experiment. • The business model, and the ownership structure of community shared solar affect its potential adoption. • The interpersonal communication and public promotion of community shared solar program can increase its popularity.

Energy efficiency in buildings remains an important priority for the European Union. Towards that direction, therole of the one-stop-shops (OSSs) that will offer integrated renovation services has been further enhanced. Thepaper aims to compare public and private-driven OSSs to increase knowledge regarding the way they operate.The business models of ten OSSs for renovation of residential buildings, operating in six European countries havebeen analysed, and further evaluated for their engagement in the critical moments of the renovation customerjourney. Findings show that the majority of examined OSSs have managed to reach some level of standardizationin the way they deliver their service. Additionally, the examined OSSs appear to be engaged in the critical momentsof the renovation customer journey, which can attract the interest of potential customers. Public-drivenOSSs appear to operate smoother in the renovation market and offer services that are considered crucial for theirpotential customers. Their viability though in the absence of public funding needs to be further examined. On theother hand, private-driven OSSs are called to deal with greater challenges in their effort to consolidate their presencein the renovation market. Providing access to financing remains a challenge for private-driven OSSs, whichto attract more customers resort to value additions to their service, which might affect their viability. The studyprovides valuable information and insights about OSSs in operation that could be useful to stakeholders that areactive in the renovation market or interested to enter it. • Analysis of ten one-stop-shop business models for residential building renovations operating in six European countries. • Operational modality of public and private driven OSSs has been critically reviewed and compared. • Public-driven OSSs appear to operate smoother in the renovation market offering services that are considered crucial by customers. • Private-driven OSSs are dealing with greater challenges in trying to consolidate their presence in the renovation market. • Private-driven OSS build trust with their customers by engaging in specific "critical moments" of the renovation journey and by adding value to their service.
