Recent advances in solar irradiance monitoring devices and calibration methodsFunded under: FP1-ENNONUC 3C
A study was undertaken to determine and validate a cost-effective in situ calibration method for silicon solar sensors used in PV plants and to identify a reliable sensor design with a stable lifetime comparable to that of the modules. This paper summarises: (i) the present state-of-the-art devices used for monitoring solar irradiance mostly by the PV community; (ii) practices employed by device suppliers and users in calibrating such devices, and (iii) preliminary results of concerted action studies being carried out by several test centres in Europe regarding the use of Si-based devices and their calibration methods. It is observed that the simplified calibration method is effective and suitable for system designers, installers and operators, and that the Si-based devices evaluated (mainly monocrystalline) are cost-effective substitutes for the thermopile pyranometers.
