SOLAR ENERGY IN PORTUGAL - Development perspectives based on a comparison with Germany - Rodrigo Pedro da Piedade Coelho Virgilio Project submitted as partial requirement for the conferral of Master in International Management Supervisor: Prof. António Robalo, Prof. Catedrático, ISCTE Business School, Departamento de Gestão September 2009 Resumo A energia solar é uma das energias renováveis que apresenta maior potencial de desenvolvimento futuro. Portugal é um dos países da Europa com melhores condições para a utilização da energia solar, mas não é certamente um dos países que melhor as têm aproveitado. Interessa, pois, saber porque é que Portugal não tem aproveitado a energia solar e potenciado o seu desenvolvimento de acordo com a sua vasta disponibilidade. Por outro lado, a Alemanha tem aproveitado a energia solar como nenhum outro país e é actualmente uma das nações líderes neste sector. Através de um estudo comparativo dos mercados de energia solar fotovoltaica e solar termal de Portugal e da Alemanha, concluiu-se que a diferença de desenvolvimento entre os dois países é em grande parte resultado das diferentes políticas adoptadas. Ou seja, o desenvolvimento da energia solar depende não só da radiação solar de cada país, mas sobretudo das políticas adoptadas para promover o seu desenvolvimento e dinamizar os respectivos mercados. De acordo com as conclusões deste estudo comparativo e tendo em consideração as futuras tendências do sector da energia solar, foram definidas uma série de orientações estratégicas para o futuro desenvolvimento da indústria solar em Portugal.

Portugal is one of the European countries with better solar conditions, but is certainly not one of the countries that has been taking the best advantage of it. It is therefore appropriate to know why Portugal is not using and developing solar energy in accordance with its wide availability. On the other hand, Germany is using solar energy as no other country and is currently one of the leading nations in this sector. After a comparative study of the photovoltaic and solar thermal markets in Portugal and Germany, the conclusion is that the different stage of development between the two countries is largely the result of the different policies adopted. That is, the development of solar energy depends not only on the solar radiation of each country, but above all on the policies adopted to promote its development and enhance these markets. According to the findings of this comparative study and taking in consideration the trends in the solar energy sector, a set of strategic guidelines for the future development of solar industry in Portugal was defined.
