During a few years, the photovoltaic (PV) market has shown unprecedented growth and wide-spread use of this environmentally friendly and distributed source of power generation. On a global basis, new PV installations approximately varies between 78 GW and 82 GW in 2016 and estimates for 2017 are in the 80–85 GW range.

For the 6th year in a row, solar power with 56% of total investment representing USD 161 billion (EUR 146 billion) took the largest share of new investments in renewable energies. These investments were almost evenly shared between large scale solar power and distributed solar energy systems.

The most impressive result is however the number of installations and therefore of individuals, companies, and public entities participating in this development: nearly 2 million single PV installations produce photovoltaic power already today.

The strong growth in PV installations is currently …
