Manual de calibración de piranómetros usando un piranómetro de referencia según la norma ISO 9847 : Calibración de instrumentos de medición solar (Piranómetros).

Abstract

Solar radiation is humanity’s oldest source of energy. Its understanding from various fields of knowledge has been a constant throughout the history of humanity. For example, it has been studied in the context of energy utilization through the implementation of solar technologies, or in the field of health, analyzing the influence of UV radiation on people’s skin. Due to its great importance, it is necessary to have instruments capable of measuring solar radiation accurately and reliably. One such instruments is the pyranometer, design to measure global solar irradiance in a horizontal plane. These instruments are constantly exposed to environmental factors such as humidity and heat, making them susceptible to measurement misalignments. For this reason, this document (TIC) will present a theoretical and experimental justification for the preparation of a pyranometer calibration manual, according to the ISO 9847 standard. Mainly, this calibration manual will be aimed at the technical personnel in charge of supervising these instruments, so its content has to be reliable and clear. Throughout the development of the TIC, two calibration processes were analyzed with the method (type Ia) in different sky conditions, in order to analyze the adjustment between the test and standard pyranometer, in each calibration process.
