US 2021/0249550 A1 · DOUBLE-SIDED LIGHT-CONCENTRATING SOLAR APPARATUS AND SYSTEM

Abstract

A double-sided light-concentrating solar apparatus and system. The apparatus comprises a front-side concentrating groove (110), a back-side concentrating groove (110′), and a photovoltaic panel (120) provided at the bottom of each concentrating groove. Each concentrating groove comprises two groove walls (111, 112; 111′, 112′) extending along the bottom; opposite surfaces of the two groove walls are reflecting surfaces; the open side of each of the two groove walls forms an opening of the concentrating groove; the opening direction of the front-side concentrating groove (110) is opposite to the opening direction of the back-side concentrating groove (110′). According to the double-sided concentrating solar device, sunlight (LL) can be concentrated and received from two different directions, thereby enhancing direction adaptability and expanding device mounting methods.
