Calibration of Pyranometers (and more broadly – of the entire group of solar radiation measuring instruments) consists in comparing their measurements with those obtained using a pyranometer recognized as a reference. The reference instrument, in turn, must first be corrected and verified in an accredited metrological laboratory.
Benefits of Calibration
The benefits of carrying out the pyranometer calibration process include:
- Measurement reliability
Regular calibration ensures that pyranometers provide accurate measurements of solar radiation intensity, which is crucial in many fields such as meteorology, photovoltaics, and climate research. Measurement errors can lead to misinterpretation of data, inaccurate forecasts, financial losses in photovoltaic systems, and reduced quality of scientific research. - Compliance with standards and requirements
Many industrial standards, norms, and regulations require regular calibration of pyranometers to ensure compliance and measurement precision. - Error prevention
Calibration enables the early detection of any deviations from expected measurement results, allowing for quick correction and minimizing the risk of errors. - Increased confidence
Regular calibration of pyranometers contributes to greater trust in the obtained measurement results.
Calibration Regulations
There are regulations obligating pyranometer users to perform periodic calibrations. Depending on the country and industry, there may be different requirements concerning the frequency and procedures of pyranometer calibration. For pyranometers used in photovoltaics, for example, the calibration frequency is determined by the photovoltaic panel manufacturer. It is also advisable to thoroughly review national regulations governing these issues. Many pyranometer manufacturers recommend performing calibration at least once a year to ensure continuous measurement accuracy.
Both accredited and non-accredited metrological laboratories provide pyranometer calibration services. In addition to accreditation, it is important that the individuals performing the calibration have the appropriate qualifications. Metrologists should have experience and relevant certifications that guarantee high quality and reliability.
