The GPM analyses show that full grid parity has been reached in several countries: Australia, Chile (Copiapó), Germany, Italy, Japan and Mexico for DAC consumers. The decreasing trend of installation costs, one of the main drivers of the cost of PV generation (expressed as LCOE), has recently slowed down in mature markets. Overall, from 2009 to 2014, the LCOE in the residential segment decreased in all of the cities analysed: from a 28% annual decline in Australia to a 5% in Spain.
