5. Potential of solar energy What is Photovoltaics (PV)? Photovoltaics means turning daylight directly into dc electricity Done by photovoltaic cells (PV cells), assembled into PV modules  There are no moving parts  There is no 'fuel', apart from daylight  The modules need no maintenance  In principle, almost indefinite lifetime PV works with both direct sunlight and indirect daylight (more light = more power) Photovoltaic is the most elegant way of producing electricity

6. Potential of solar energy Grid-connected system – the main components 1 Solar modules 2 Array box 3 DC switch (optional) 4 Inverter 5 AC switch (optional) 6 Energy meters 7 House distribution box 8 Net connection  Connected in parallel with the public network  The systems work as small distributed power plants  The system does not have any energy storage – the grid serves as an energy storage balancing the load and production mismatch. 1 2 3 4 5 6 7 8

10. Photovoltaic markets World market – annual installed PV capacity  Average growth during last 15 year has been 25%  Grid connected systems dominating (98% 2010)  Large central power plant increase share and Asia market area  Top 5 markets 2010: Germany, Italy, Czech, France, USA, (appr. 80% of the markets). Japan and China to replace soon Cz and Fr. MW p Unforeseeable strong market incereases upwards: 2007- 2008 (120%, Spain), 2008-2009 (inspite of spanish market collapse) and 2009/2010 (Germany, Italy).
