研究目的
Investigating the optimal tilt angle for photovoltaic panels in Barcelona to maximize solar energy capture and increase energy generation efficiency.
研究成果
The study concludes that adjusting the tilt angle of photovoltaic panels according to monthly, seasonal, and annual optimal angles significantly increases solar energy capture and energy generation efficiency in Barcelona. The annual optimum tilt angle is found to be 36.87?, leading to a 10.54% increase in energy generation compared to horizontal placement.
研究不足
The study focuses on Barcelona and may not be directly applicable to other locations without adjustments for local climatic and geographic conditions. The method improves upon the KT method but still relies on categorization of sky conditions which may not capture all variability.
1：Experimental Design and Method Selection:
The study uses the KleinThekilacker method (KT method) improved by considering sunny, semi-cloudy, and cloudy days to find the best optimum tilt angle.
2：Sample Selection and Data Sources:
The city of Barcelona is selected for its favorable solar energy conditions. Data includes solar radiation on horizontal surfaces and monthly temperatures.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
Calculation of solar radiation on tilted surfaces using mathematical models considering direct and diffuse irradiation, and the effect of tilt angle on solar radiation capture.
5：Data Analysis Methods:
Comparison of solar radiation and energy generation using horizontal versus optimal tilt angles, and analysis of monthly, seasonal, and annual optimal tilt angles.
