New concepts are presented for solar mirrors : 1) Integration of aluminum first and second surface mirror ; 2) Composite aluminium first surface mirror with double layer and 3) Combination of integrated and composite mirrors. These concepts allow the mirrors to have longer life in spite of the corrosion phenomena. The total solar specular reflectance of these rnirrors is 0.85-0.86 before and after ageing tests for first surface films and 0.73 for second surface films.
