Barriers and potential solutions to the diffusion of solar photovoltaics from the public-private-people partnership perspective - Case study of Norway

Norway is a major renewable energy developer in Europe, mainly through its development of hydropower. Research has shown that solar energy also has potential in Norway, however, the cumulative installed photovoltaic capacity was only 120 MW at the end of 2019, representing 4.1% of the total electricity generation. Hence, this paper aims to investigate the main barriers to diffusing photovoltaics for residential buildings from the public sector, private sector, and the people's perspectives in Norway. Furthermore, it analyzes solar development, policies, and models in different countries, and proposes a potential model and solutions to overcome barriers. The results show that the high initial costs of photovoltaics and limited information and awareness of the possible benefits are the main barriers for the people. For the private sector, limited funding and few pilot projects to learn from, as well as risk uncertainty are the main barriers. The main concern in the public sector is the low application of existing incentives. Public-private-people partnerships (PPPP) have a big potential to overcome these barriers by dividing the high initial costs into more affordable sums, facilitating the information flow among different sectors, and involving all three sectors to create new incentives. In addition, Norway is well-suited for PPPP, as the citizens pay much attention to sustainable development, and there is already a close collaboration between the public and private sectors in the energy sector. Finally, three concrete solutions using PPPP are proposed: design a co-investment solution, provide information sharing platforms, and create new incentives.

Automated summary

Norway is a major renewable energy developer in Europe, with a focus on hydropower, but research shows that solar energy also has potential. However, barriers to diffusion of photovoltaics in Norway include high initial costs and limited awareness of benefits. Public-private-people partnerships have the potential to overcome these barriers and create new incentives in the country.
