研究目的
Investigating the effects of solar tracking systems on the performance of photovoltaic power plants to enhance solar energy generation.
研究成果
The study concludes that solar tracking systems, particularly single-axis and double-axis trackers, significantly enhance the efficiency of solar power plants compared to fixed panel systems. However, in certain conditions like overcast skies and high latitudes, the benefits of tracking systems diminish, suggesting the need for adaptive strategies that can switch between tracking and fixed modes based on environmental conditions.
研究不足
The study acknowledges that in overcast and cloudy conditions, especially in high latitudes, the tracking systems may not provide significant advantages over fixed panel systems. Mechanical friction, wind loading, and external disturbances are noted as factors that could affect performance but were not deeply analyzed in this study.
1：Experimental Design and Method Selection:
The study involves the design and implementation of single-axis and double-axis solar tracking systems to compare their efficiency with fixed panel systems. Theoretical models and practical implementations are discussed.
2：Sample Selection and Data Sources:
The study uses photovoltaic panels and sensors (LDRs) for detecting sun position. Data on solar irradiance and energy output are collected under various conditions.
3：List of Experimental Equipment and Materials:
Includes PV panels, LDR sensors, servomotors, microcontrollers (PIC18F4520), and batteries.
4：Experimental Procedures and Operational Workflow:
Detailed steps include setting up the tracking systems, calibrating sensors, programming microcontrollers for automatic and manual modes, and comparing energy outputs.
5：Data Analysis Methods:
The efficiency of tracking systems is calculated by comparing the energy output with fixed panel systems. Statistical analysis is performed to validate the results.
