Solar energy is the name given to radiation from the Sun and is one of the most important aspects of renewable energy. Electricity production from solar sources is possible through photovoltaic solar panels. When solar radiation strikes photovoltaic cells, part of it is directly converted into electrical energy through the so-called "photovoltaic effect". In Portugal, the availability of this resource is high, as is the potential for its use, not only due to the country's geographical location, but also because production occurs mainly during peak daytime electricity consumption hours, fitting the load diagram profile as an essential complement to other renewable generation technologies present in the national electricity mix.
