A solar condenser, comprising two or more parabolic mirrors; each parabolic mirror is provided with a different focal length and a common focusing plane; the parabolic mirrors consist of a plurality of staggeredly arranged mirror unit groups consisting of more than one reflecting units; the distance between every two parabolic mirrors with different focal lengths is the focal length difference thereof. Through the staggered installation of the reflecting units, the air flow between the mirrors is increased without increasing additional footprint or affecting the light-focusing effect, thus the impact of winds on the mirrors and structures is reduced; and ice, snow and dust do not easily accumulate on the mirrors, thus effectively improving the operational stability of the solar condenser.
