Abstract
It is a fact that current society tends to the energetic diversification and to the sustainability for the future growth. In this process the knowledge of the different energetic renewable systems and inside them, the photovoltaic solar energy, plays a fundamental role. The new global conscience in questions of Environment, especially for the need to promote at every level the use of clean or renewable energies, make foresee important technological changes for the first years of the second millennium. The electricity of photovoltaic origin appears, on a worldwide scale, as one of the most important alternatives to satisfy the energetic needs in those cases in which it is needed to have clean, sure and quality energy compatible with sustainable development policies. The photovoltaic solar energy has met particularly favoured during last years in Greece for the diverse legislations and regulations promulgated recently and for the institutional support given to the development of the sector. Greek government is ambitious when it comes to PV energy, with the goal of having installed at least 700 MWp by 2020. Within this framework, in June 2006 a new feed-in tariff system was launched in Greece, guarantying €0.40 to €0.50 per kWh for the next 20 years. Accompanied by a relaxation of the licensing procedure and the possibility for combination of these benefits with investment grants and subsidies between 30 to 55%, the payback time of PV investment becomes very interesting in this sunny country, getting an even better return on investment than in Spain in certain market segments. Following this line of work, in the present report we make a complete analysis on the first Greek installation fitting the new regulatory framework, which will be useful to show the viability of solar power at Aristotle's country.
