AFIQ.ER is an employers’ association set up to defend the interests of manufacturers and importers of firing equipment, which has now evolved into solar thermal. This evolution of the AFIQ.ER association has taken place as the market has evolved, while maintaining the same market operators. As there is no Portuguese association for solar thermal, the association has seen this positive development for its members. Overall, AFIQ.ER understands itself as an association for the defence of solar.
