According to the condenser structure with "Fresnel" lens, parabolic mirror and heliostat.
Flat reflectors are used in tower solar plants with tracking equipment and are typically used in conjunction with parabolic mirrors. Plane mirror to focus the sun reflected in the parabolic mirror, parabolic mirror to focus.
