Environmental and economic analysis of solar systems in Madeira, Portugal

The solar market started growing in Madeira from 2008 to profit from great solar exposition. Initially, there was a strong investment, but the removal of the Feed-in Tariffs, and self-consumption regulations caused stagnation in new solar systems. This policy change is relevant to check the current lack of investments and an analysis of the environmental and economic effects over a decade is necessary to help defining the solar policy for the next decades. Results show savings of 100 thousand tons of CO2 and 38 million euros supporting the need of policy reversal to address a change in the net-metering regime.
