Primary Reference Cell Calibrations

Primary reference cells are calibrated for in-house use and for use by other national laboratories to provide clients and partners with a path for traceability to standards.

Our laboratory is one of only four facilities in the world certified to calibrate reference cells in accordance with the World Photovoltaic Scale, and these measurements are accredited to International Organization for Standardization 17025 standards. We are the only laboratory certified to calibrate primary reference cells, secondary reference cells, secondary reference modules, cells, and modules.

Once we obtain a reference cell, we subject it to carefully devised calibration procedures that minimize errors from the temperature-dependent spectral correction. Read about the accuracy of NREL's PV performance measurements.
