Le bilan environnemental (carbone, energie) de trois capteurs solaires thermiques produits en Belgique de 1979 a nos jours est propose, en tenant compte des postes suivants : la production des matieres premieres, leur mise en forme. Les impacts respectifs de chaque fraction de materiau sont evalues. Le bilan est compare avec les performances de ces capteurs, qui permettent de reduire la consommation en energies fortement emettrices de CO 2 . Le temps de retour energetique s’ameliore sur le long terme, grâce a une meilleure selection des materiaux. Le benefice de la reutilisation de certains composants est evalue, en tenant compte de la facilite de demontage.
