Hanne.Saele@sintef.nocis-8.1.1201907052019123120191229Solar power or photovoltaic (PV) systems have emerged as a leading low-carbon energy technology worldwide, but the deployment of residential PV systems in Norway has lagged behind other Scandinavian countries. Therefore, the Norwegian market provides an opportunity to gain insights on the demand factors that determine residential PV adoption. This paper presents results from a stated-preference survey designed to elicit household knowledge, preferences and willingness to pay for residential PV systems. Results suggest that meaningful growth in residential PV capacity depends greater knowledge among households, continued advances in technology, clarity with the grid tariff and stronger support systems. A review of recent experiences in the field corroborates the important role of effective regulatory structures and support programs.
