2. 2 SOLARPHOTOVOLTAIK Preamble Europe has, like Japan, defined PV solar electricity as one of the most important future key technologies. In order to enable the production industry to develop competitively, market support programs were encouraged in the EU member states. This, however, will only be supported as long as a strong EU based production industry in harmony with the market size can be established. The industry from the most important world economy regions (Japan, Europe, US, SEA) should proactively secure their local market developments in correspondence with the respective local industry capacity increase.
