Solar energy utilization device

A solar energy utilization device, comprising:

• a light energy utilization unit having a light energy utilization portion capable of receiving, converting and utilizing sunlight, wherein the light energy utilization portion is divided into a first light energy utilization portion and a second light energy utilization portion arranged away from each other;
• and
• a first liquid condensing unit group and a second liquid condensing unit group, the first liquid condensing unit group concentrating the sunlight to the first light energy utilization portion, and the second liquid condensing unit group concentrating the sunlight to the second light energy utilization portion;
• wherein each liquid condensing unit group comprises two adjacent liquid condensing units which are arranged on a same side of the light energy utilization unit,
• each liquid condensing unit has a closed cavity being filled with a transparent liquid therein, a cavity wall of the closed cavity comprising a light receiver capable of transmitting sunlight into the transparent liquid, a reflector for reflecting incident sunlight and a condenser, the transparent liquid being in contact with the light receiver, the sunlight in each liquid condensing unit transmitted from the transparent liquid to the light receiver forming a total reflection phenomenon so as to concentrate the sunlight onto respective light energy utilization portion,
• the transparent liquid of the two adjacent liquid condensing units is communicated in each of the liquid condensing unit groups, the light receivers of the two adjacent liquid condensing units are connected to each other with a V-shaped connecting section in each of the liquid condensing unit groups,
• wherein the light energy utilization unit is arranged vertically, the first liquid condensing unit group and the second liquid condensing unit group are distributed in an X shape, and upper ends of the first liquid condensing unit group and the second liquid condensing unit group define a cavity with an upper opening.
