Mir-Artigues P., Cerda E. & Del Rio P. (2015) Analyzing the impact of cost-containment mechanisms on the profitability of solar PV plants in Spain. Renewable and Sustainable Energy Reviews 46: 166-177

Abstract. From mid-2007 to September 2008, the Spanish PV sector experienced an investment boom, which led to a ten-fold increase in solar PV deployment. The concern of the government about the large increase in the associated support costs through a feed-in tariff led to the implementation of several cost-containment regulations.
