Solar Panel Sun Tracking with Reflective Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar energy systems are limited in energy production due to fixed positions relative to the sun, resulting in inefficiencies as solar panels do not face the sun as it moves across the sky, and they fail to utilize indirect sunlight effectively.
Innovation Solution
A solar energy system that includes a sun-tracking device with a base assembly, carriage assembly, and orientation sensor assembly to rotate photovoltaic devices to align with the sun's azimuth position, combined with reflective panels to concentrate additional sunlight onto the panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are positioned at a fixed orientation, then the system structure is simple and stable, but the amount of direct sunlight collected is limited because the panels cannot follow the sun's movement across the sky
Solution Approach 1:
The patent applies the dynamics principle by implementing a sun-tracking mechanism that enables solar panels to dynamically adjust their orientation throughout the day. The system uses motors and gear drives to rotate the panels, allowing them to follow the sun's movement across the sky and maintain optimal perpendicular alignment, thereby maximizing direct sunlight collection and energy production
Solution Approach 2:
The patent implements feedback through orientation sensors (such as light sensors or position sensors) that continuously detect the sun's position or the panel's orientation angle. This feedback information is used by a control system to adjust the panel positioning in real-time, ensuring the panels remain optimally aligned with the sun throughout the day
2Productivity
If reflector panels are added to concentrate peripheral sunlight, then the amount of sunlight impinging on solar panels increases, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies the dimensionality change principle by adding reflector panels positioned at the periphery of the solar panel array. These reflectors capture sunlight that would otherwise fall outside the active collecting area and redirect it onto the solar panels, effectively expanding the functional sunlight collection area without increasing the physical footprint of the solar panels themselves
Solution Approach 2:
The patent uses reflector panels as intermediary elements that mediate between the peripheral sunlight and the solar panels. The reflectors act as intermediate surfaces that intercept sunlight falling outside the direct collection area and redirect it onto the solar panels, thereby increasing the total sunlight utilization without requiring larger solar panels
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system significantly increases the amount of direct sunlight impinging on photovoltaic devices, enhancing energy collection efficiency by dynamically tracking the sun's position and reflecting peripheral sunlight, thereby boosting overall energy production.
Implementation Method 1
Photovoltaic (PV) devices, such as solar panels, are used to collect convert incident radiation from the sun (sunlight) into electricity
Implementation Method 2
attach one or more reflector panels at the outer periphery of the sunlight-collecting surfaces of the solar panels to reflect and concentrate incident sunlight on to the sunlight-collecting surfaces
