13 2. PV INDUSTRY TRENDS

14 PV INDUSTRY TRENDS

Global Developments

. Shift from Europe to Rest of the World

. Dramatic / retroactive support cuts

. Legislation changes and lack of direction

. Low confidence from investors Veules les Roses | France

. Long & painful correction:

 Further M&A activity / consolidation

 Bankrupcies (warranties?)

. Grid parity vs incentive schemes

. Service vs Product

Duransol | France

15 PV INDUSTRY TRENDS

Polish market Challenges

. Rules clarification (legal & technical)

. PV projects development (ready to build)

. Incentive Scheme definition (GC, PPA, FIT?)

. Market size & the Polish RES objectives

. Electricity market development

. Long term market stability & sustainability

. Investment capacity

. Investment attraction

16 PV INDUSTRY TRENDS

Lessons from our experience

. Legaslative clarity & stability are key

. Changes shall be planned in advance

. Clear and objective stratagy for RES

. Risk perception for Investors

. Tax & Investment incentives are important

. Secure project financing at an early stage

. Opex is as important as Capex ARUBA Business Centre | Slovakia . There is room for all
