研究目的
To analyze the performance of a 12 kWP rooftop grid-connected photovoltaic plant installed under net metering in Delhi, India, focusing on various performance parameters.
研究成果
The annual average energy generated was 1147 kWh/kWp with a performance ratio of 85-93%, the highest among other PV plants in India. The study highlights the effectiveness of rooftop grid-connected PV plants under net metering in urban areas like Delhi.
研究不足
The plant was non-operational for 86 days due to inverter malfunctioning, power cuts, and maintenance work. Energy generation was also affected by shadows from nearby structures and bird droppings on the modules.
1：Experimental Design and Method Selection:
The performance analysis is based on the evaluation of various performance parameters such as monthly average reference, array and final yield of PV plant.
2：Sample Selection and Data Sources:
The analysis uses data from a 12 kWP rooftop grid-connected PV plant installed in Delhi, India.
3：List of Experimental Equipment and Materials:
The plant includes PV modules, an inverter, digital energy meters, a pyranometer, and temperature probes.
4：Experimental Procedures and Operational Workflow:
Data on AC/DC voltage, current, and energy generated by the PV plant, along with solar irradiance and temperature, are recorded at 5-minute intervals.
5：Data Analysis Methods:
Performance parameters are calculated using formulas from the IEC 61724 standard guidelines.
