Catalonia’s Telecommunications and Information Technology Centre (CTTI) invests in sustainable solar energy using Salicru technology. The project uses EQUINOX2 solar inverters. The use of solar energy by the public administration reduces environmental impacts by lowering the dependence on fossil fuels and implies a representative saving in long-term energy costs. By incorporating these solutions, organisations such as the CTTI become benchmarks for social responsibility and energy efficiency, aligning themselves with global targets for reducing emissions and caring for the environment.
