- India inaugurated the world’s fifth National Primary Standard Facility for Solar Cell Calibration at CSIR – National Physical Laboratory, New Delhi.
- The facility provides high-precision calibration of solar cells to ensure accurate photovoltaic (PV) measurements.
- It uses a laser-based Differential Spectral Responsivity (DSR) system for calibration.
- The facility achieves a low measurement uncertainty of about 0.35%, meeting global standards.
- It was developed in collaboration with PTB (Physikalisch-Technische Bundesanstalt), Germany.
- The facility reduces India’s dependence on foreign solar calibration and supports the domestic solar industry.
