Solution Overview
Problem
Current light-concentrating solar systems are limited by their single-sided light-receiving method, restricting installation options and power generation time, especially without sun-tracking systems, necessitating a cost-effective and adaptable solution.
Innovation Solution
A double-sided light-concentrating solar apparatus with front-side and back-side light-concentrating grooves and shared or offset photovoltaic panels, utilizing reflective surfaces such as mirrors or Fresnel lenses to receive sunlight from two directions, enhanced by side reflective panels for improved light collection and concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-sided light-receiving method is used, then the device structure is simple, but the adaptability to different directions and installation methods is limited
Solution Approach 1:
The patent transitions from single-sided to double-sided light receiving by adding a second receiving surface in an opposite direction. The apparatus includes a first light-receiving surface facing a first direction and a second light-receiving surface facing a second direction opposite to the first direction, enabling light collection from both sides simultaneously.
Solution Approach 2:
The light-receiving structure is divided into separate first and second light-receiving surfaces with independent concentrating grooves on each side. This segmentation allows each surface to independently collect and concentrate light from its respective direction, improving overall adaptability.
2Productivity
If a single-sided light-receiving method is used, then the device structure is simple, but the light collection ability is limited
Solution Approach 1:
The patent transitions from single-sided to double-sided light receiving by adding a second receiving surface in an opposite direction. The apparatus includes a first light-receiving surface facing a first direction and a second light-receiving surface facing a second direction opposite to the first direction, enabling light collection from both sides simultaneously.
Solution Approach 2:
The patent combines two light-receiving surfaces into a single integrated apparatus, merging the functionality of separate single-sided devices. The first and second concentrating grooves work together to concentrate light from both directions onto their respective photovoltaic panels, doubling the light collection capability.
3Area of stationary object
If the opening lateral dimension is larger than the bottom lateral dimension, then the light collection area is increased, but the light concentration ratio is reduced
Solution Approach 1:
The light-receiving structure is divided into separate first and second light-receiving surfaces with independent concentrating grooves on each side. This segmentation allows each surface to independently collect and concentrate light from its respective direction, improving overall adaptability.
Solution Approach 2:
The patent employs reflective surfaces with specific geometric configurations (parabolic, Fresnel, or planar) to optimize the balance between collection area and concentration ratio. By changing the geometric parameters of the reflecting surfaces, the system achieves both large opening areas for light collection and appropriate concentration ratios for efficient energy conversion.

AI summary
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.
