Abstract
The determinants to the deployment of renewable energy technologies in general and solar PV in particular are multifaceted. They include technoeconomic factors (e.g. resource potentials and investment and variable costs), legal and administrative barriers, political factors, social acceptability and other factors (e.g. subsidies and other advantages to fossil fuels, lack of information, human capital factors and the role of pioneers) (del Río in Renew Sustain Energy Rev 15(5):2520–2533,
2011). However, public policies have been a critical driver in this context. In fact, solar PV has been, and to large extent still is, policy-driven. Relevant aspects with respect to support for solar PV include framework conditions, instruments, design elements within the instruments and the stability of support.
