Solution Overview
Problem
Traditional solar power generation systems face inefficiencies due to limited sunlight absorption rates caused by incorrect solar panel installation directions, environmental factors, and shading issues among multiple panels, leading to reduced energy output.
Innovation Solution
A solar power generation apparatus with a tracking method that adjusts the rotational angle of solar panels based on the sun's elevation and azimuth, incorporates a differential angle processing unit to correct installation errors, and implements a shade avoidance mode to optimize sunlight absorption by determining the optimal angle for each solar panel, using data from weather observation systems and pre-programmed conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple solar panels are installed on a vast area to avoid shading, then shading between panels is reduced, but land area requirement and power transmission complexity increase
Solution Approach 1:
The solar panels are equipped with tracking systems that enable them to dynamically adjust their orientation and position throughout the day to follow the sun's movement. This dynamic adjustment allows panels to maintain optimal angles for sunlight absorption while being installed in closer proximity, thereby reducing the land area required while preventing shading interference between adjacent panels.
2Ease of manufacture
If solar panels are installed in a fixed orientation to simplify installation, then installation complexity is reduced, but sunlight absorption efficiency decreases due to incorrect installation direction and environmental factors
Solution Approach 1:
The system employs tracking mechanisms that automatically adjust panel orientation based on the sun's position, compensating for installation location variations and environmental factors. This dynamic adjustment ensures optimal sunlight absorption throughout the day while allowing for relatively simple initial installation configurations.
Solution Approach 2:
The system incorporates sensors and control systems that continuously monitor the sun's position and panel orientation, providing feedback to automatically adjust panel angles. This feedback mechanism compensates for installation errors and environmental variations, maintaining high sunlight absorption efficiency without requiring extremely precise initial installation.
3Device complexity
If a sensor-based tracking system is used to track the sun, then the structure is simple, but the sensing range is limited and tracking fails when the sun is blocked or passes the sensing range
Solution Approach 1:
The tracking system integrates multiple functional components including sensors for sun position detection, programmable control units for calculating optimal angles based on geographical location and time, and actuators for panel adjustment. This multi-functional approach allows the system to maintain reliable tracking whether the sun is directly visible or obscured by clouds, combining the simplicity of sensor-based systems with the robustness of program-based systems.
4Area of stationary object
If solar panels are installed closer together to reduce land area, then land usage efficiency improves, but shading between panels increases reducing energy output
Solution Approach 1:
By equipping closely-spaced panels with dynamic tracking capabilities, each panel can independently adjust its orientation to follow the sun's movement throughout the day. This dynamic adjustment ensures that even panels installed in close proximity can maintain optimal sunlight absorption angles without shading each other, thereby preserving high energy output while maximizing land area utilization.

AI summary
A solar power generating apparatus and a solar tracking method for the same. When a plurality of solar collector plates are arranged, the solar collector plates may be adjusted at certain rotation angles to maintain a high level of solar absorption efficiently with respect to shade, and errors caused by the installed positions (particularly, the installed directions) of the solar collector plates having solar cells can be compensated for, to accordingly calculate and determine adjustment angles in order to accurately rotate the solar cells or solar collector plates to a desired direction and to increase solar absorption efficiency.
