Solution Overview
Problem
Conventional tracking photovoltaic generators require a motor for each solar module, increasing production and installation costs due to the need for time-based sun orientation adjustments.
Innovation Solution
A tracking photovoltaic generator that uses a linear actuator to rotate multiple solar modules in groups, reducing production costs by allowing simultaneous rotation or stopping of all modules with a single mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a motor is provided for each solar module to adjust orientation according to sun location, then the photovoltaic power generation efficiency is improved, but the production and installation costs are increased
Solution Approach 1:
The patent merges multiple individual motor functions into a single linear actuator that controls a common support bar. This single actuator simultaneously adjusts the orientation of multiple solar modules by moving the support bar, which is connected to all modules. This consolidation reduces the number of motors from multiple individual units to one shared unit, thereby lowering production costs while maintaining the ability to track sun movement and optimize power generation efficiency.
2Measurement precision
If multiple motors are used for each solar module to track the sun, then the sun orientation tracking accuracy is improved, but the installation complexity is increased
Solution Approach 1:
The patent combines multiple independent motor-driven tracking systems into a single linear actuator-based control system. The linear actuator moves a common support bar that all solar modules are attached to, ensuring they track the sun simultaneously. This unified approach simplifies installation by reducing the number of components to install and configure, while still achieving accurate sun orientation tracking through the centralized control mechanism.
Solution Approach 2:
The support bar serves as a universal component that performs the tracking function for multiple solar modules simultaneously. Instead of each module having its own dedicated motor and control system, the support bar acts as a multi-functional element that, when moved by the single linear actuator, adjusts the orientation of all connected modules. This universal component reduces installation complexity while maintaining tracking accuracy across the entire array.
