Spatio-Temporal Mapping of the Diffusion of Residential Solar Photovoltaic Technology in Luxembourg (2017-2023)

Residential Solar Photovoltaic (RSPV) systems represent a viable and bottom up mechanism for advancing partial energy autonomy and enhancing national energy resilience.Through observation or government statistics it can be acknowledged that we have witnessed an increase in their implementation in the last 10 years driven by advances in the technology and early adopters with eco-centric viewpoints embracing these new decentralised forms of energy production.In Luxembourg (and across Europe) we have observed a rapid increase in RSPV implementations occurring over the last 3 years.This has been driven by the need for price stability and affordability as well as very favourable subsidies.Nonetheless, a myriad of barriers hinder progress, spanning from overarching national policies and inadequate incentives that favour the most affluent in society to individual preferences and attitudes based on worldviews or confidence in understanding the technology.Literature suggests that the visibility of RSPV installations can both impede and facilitate diffusion, influenced by societal dynamics and differences.
