Accredited PV measurement and calibration lab

Over 25 years of PV research excellence, a meticulous characterisation of the measurement infrastructure and comprehensive uncertainty analyses culminated in CREST establishing the UK’s only accredited photovoltaic calibration laboratory: The CREST Photovoltaic Measurement and Calibration Laboratory (CPVMCL).

CPVMCL is UKAS (United Kingdom Accreditation Service) accredited to ISO/IEC 17025:2017 for the calibration of photovoltaic cells, modules and pyranometers.

Find out more about our ISO/IEC 17025:2017 accredited measurements below:

I-V curve measurements

Current-voltage measurements at Standard Test Conditions (STC) according to IEC60904-1.

Spectral responsivity measurements

PV device response to quasi-monochromatic light is measured using an over-illuminating system.

Irradiance Sensor Calibration

Reference cell and pyranometer calibration.

Further measurements

We provide a wide range of indoor and outdoor measurements to support energy yield predictions, energy rating of modules, reliability and durability investigations, support for warranty cases, etc.
