IS 16302:2016 is the Indian Standard (BIS) for photovoltaic (pv) systems - evaluation of performance. This standard specifies the procedure for measuring and analyzing the energy performance of grid-connected photovoltaic (PV) systems. It defines key metrics like Performance Ratio (PR) and system yields, and details the requirements for instrumentation, data acquisition, and reporting to verify a plant's operational efficiency.
Specifies methods for evaluating and reporting the energy performance of photovoltaic (PV) systems, including measurement and data analysis.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Primary Performance Metric | Performance Ratio (PR) and Capacity Utilization Factor (CUF) | Performance Ratio (PR) | IEC 61724-1:2021 |
| Irradiance Sensor Requirement | Pyranometer of 'Secondary Standard' or 'First Class' as per ISO 9060. | Class A monitoring requires 'Secondary Standard'; Class B requires 'First Class'. | IEC 61724-1:2021 |
| Module Temperature Sensor Accuracy | ± 1 °C | ± 1 K (for highest accuracy Class A monitoring) | IEC 61724-1:2021 |
| Reference Irradiance for PR Calculation | 1000 W/m² | 1000 W/m² (G_STC) | IEC 61724-1:2021 |
| Data Averaging Interval | Recommended 15 minutes | 1 to 60 minutes, depending on monitoring class (e.g., 1 min for Class A, 10 min for Class B) | IEC 61724-1:2021 |
| Wind Speed Monitoring | Required for systems >100 kWp, sensor at a height of 2m. | Required for Class A and B monitoring, recommended at hub height or 10m. | IEC 61724-1:2021 |
