This paper estimates demand for residential solar photovoltaic (PV) systems using a new approach to address three empirical challenges that often arise with count data: excess zeros, unobserved heterogeneity, and endogeneity of price. Our results imply a price elasticity of demand for solar PV...

Purpose Over the past decades, the global solar photovoltaic (PV) market has experienced an unprecedented development associated with a substantial decline in solar PV module prices. A body of literature has attempted to identify and evaluate the different sources of price variation. However,...

With less than 2% of new renewable energy production, Switzerland is a poor performer in international comparison. A study carried out for the Swiss Federal Office of Energy showed constraints explaining this low number. One of these is a need for companies to optimize their sales process....
