A new study by Politecnico di Milano and Eurac Research sheds light on the acceptance of photovoltaic (PV) systems in heritage contexts, through questionnaires with Italian technical stakeholders in the construction sector.

The study reveals that contrary to common belief, lack of knowledge about PV technology isn't a significant obstacle. The acceptance of PV systems in heritage contexts is primarily driven by economic and aesthetic benefits. Respondents value the enhancement of historical buildings and landscapes, discreet PV integration, and economic advantages, such as cost reduction for energy use.

Despite the positive aspects, cultural concerns, especially the perceived risk of impacting historical and natural identities, emerge as the main barriers to acceptance. The study highlights the need to address cultural and aesthetic considerations when promoting PV integration in heritage settings.

The results highlight the importance of national and local policies, clear guidelines, and economic incentives tailored for heritage contexts to promote PV acceptance. Despite the study's specific focus on Northern Italy, its methodological approach allows for future expansion and application in diverse territories.
