Résumé : The environmental balance (carbon footprint, primary energy) of three thermal solar collectors produced in Belgium from 1979 to now is presented; it accounts for the raw materials production and their manufacturing. The impact of each component is assessed. These impacts are then compared with the performance of these collectors, which reduce the consumption of carbon-intensive primary energies. The energy payback time turns out to decrease from the oldest to the newest collector, thanks to a better selection of the materials. The possible benefit or reusing some components is assessed, depending on the ease of dismantling. © 2012 EDP Sciences.
