Photovoltaics (PV) is the most popular source of renewable energy today. It offers an important option to address the environmental issue of reducing CO2 emissions, but it is still heavily demonized because of the high cost and the need for incentives for its full market penetration. However the relative figures worldwide tell us of a healthy market with two-digit annual growth, even if in some countries, mainly in Europe, it is suffering a reduction because of reconsiderations of government support policies. In Italy –which is the leading country for PV contribution to the national electric demand (8.2%)– the end of incentives has led many to declare the death of PV which however, after suffering from the initial shock, is re-stabilizing at more reasonable values, far from the past years insane growth (370 MW installed in 2016; 600 MW annual installation expected in 2020). …
