tecnun Posted August 17, 2018 Share Posted August 17, 2018 Hello Team,I don´t know really what this parameter stands for: "voltage drop across series diode", in the array losses configuration.What´s its physical meaning, was it neglicted before? or now just it is isolated for individual study. I m appying it with default value of 0,7 V but i would like to understand it better.Thanks in advance, Best R.Jose Link to comment Share on other sites More sharing options...
André Mermoud Posted August 17, 2018 Share Posted August 17, 2018 This is now obsolete, you should put 0. In old PV systems, it was a common practice (and even a rule in some countries) of putting a diode in series with each string, for avoiding drawing current from one string to anothe weaker one. This is completely useless as the string voltages are quasi-identical, whatever the irradiance or electrical losses. Therefore the diode is never activated.
