Analytical Modelling of High Concentrator Photovoltaic Modules Based on Atmospheric Parameters
International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015 The goal of this paper is to introduce a model to predict the maximum power of a high concentrator photovoltaic module. The model is based on simple mathematical expressions and atmospheric parameters. The maximum power of a HCPV module is estimated as a function of direct normal irradiance, cell temperature, and two spectral corrections based on air ...

RMS Current of a Photovoltaic Generator in Grid‐Connected PV Systems: Definition and Application
International Journal of Photoenergy, Volume 2008, Issue 1, 2008., 2008 This paper includes a definition of a new and original concept in the photovoltaic field, RMS current of a photovoltaic generator for grid‐connected systems. The RMS current is very useful for calculating energy losses in cables used in a PV generator. As well, a current factor has been defined in order to simplify RMS current calculation.
