• Resumen

  • Knowledge of solar cell operating temperature is critical to evaluate the energy performance of a HCPV module. However, the measurement of the cell temperature in HCPV modules is a very complex task due to the special features of these types of modules, so it is useful to find indirect methods to calculate this. DNI, cell temperature and I-V curves have been measured for one year in the Centre of Advanced Studies in Energy and Environment of the University of Jaen located in the south of Spain. Thanks to these measurements, cell temperature can be determinate as a function of V oc with a mean relative error of -0.38 %.
