研究目的
To present an analytical study on the performance of photovoltaic system with various azimuth angles and solar array tilt positions.
研究成果
The study concludes that the azimuth angle and tilt position of solar panels significantly affect the performance of photovoltaic systems. Optimal performance is achieved when panels are placed close to the latitude position of the selected location. The study provides valuable insights for maximizing energy production and efficiency in photovoltaic systems through proper orientation and tilt.
研究不足
The study is limited to two specific geographical locations (Chennai, India and Beijing, China) and may not be directly applicable to other regions without further analysis. The simulation relies on the System Advisor Model (SAM), and actual performance may vary due to unmodeled factors such as local weather variations and installation specifics.
1：Experimental Design and Method Selection:
The study uses an analytical approach to evaluate the performance of photovoltaic systems under various azimuth angles and tilt positions. System Advisor Model (SAM) is used as a simulation tool for both locations (Chennai, India and Beijing, China).
2：Sample Selection and Data Sources:
Data from two different geographical locations (Chennai, India and Beijing, China) are used to study the effects of azimuth angles and tilt positions on photovoltaic system performance.
3：List of Experimental Equipment and Materials:
Mono-c-Si solar modules with a module area of
4：6 m2 and module capacity of 2 DC Watts, inverters with unit capacity of 8 AC kW, and input voltage of 250-480 VDC DC V are used. Experimental Procedures and Operational Workflow:
The study involves simulating the performance of photovoltaic systems at various azimuth angles and tilt positions using SAM, analyzing the output power, and comparing the results between the two locations.
5：Data Analysis Methods:
The analysis includes evaluating planes-of-array irradiance, net to inverter output power, net to grid output power, and performance ratio to determine the optimal azimuth angles and tilt positions for photovoltaic systems.
