Photovoltaic devices - Part 5: Determination of the equivalent cell temperature (ECT) of photovoltaic (PV) devices by the open-circuit voltage method

IEC 60904-5:2011 describes the preferred method for determining the equivalent cell temperature (ECT) of PV devices (cells, modules and arrays of one type of module), for the purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell temperature) and translating measured I-V characteristics to other temperatures. The main technical changes with regard to the previous edition are as follows: - added method on how to extract the input parameters; - rewritten method on how to calculate ECT; - reworked formulae to be in line with IEC 60891.

Dispositifs photovoltaïques - Partie 5: Détermination de la température de cellule équivalente (ECT) des dispositifs photovoltaïques (PV) par la méthode de la tension en circuit ouvert

La CEI 60904-5:2011 décrit la méthode préférentielle pour déterminer la température de cellule équivalente (ECT) des dispositifs photovoltaïques (cellules, modules et champs d'un type de module), dans les buts de comparer leurs caractéristiques thermiques, de déterminer leur NOCT (température nominale d'utilisation des cellules) et de transposer les caractéristiques I-V mesurées à d'autres températures que celles de leur mesure. Les principaux changements techniques par rapport à l'édition précédente sont les suivants: - ajout d'une méthode explicitant comment extraire les paramètres d'entrée; - réécriture de la méthode explicitant comment calculer ECT; - travail sur les formules pour qu'elles soient cohérentes avec la CEI 60891.

Fotonapetostne naprave - 5. del: Določanje ekvivalentne temperature celice (ECT) fotonapetostnih (PV) naprav po metodi napetosti odprtih sponk (IEC 60904-5:2011)

Ta del IEC 60904 opisuje prednostno metodo za določanje ekvivalentne temperature celic (ECT) fotonapetostnih (PV) naprav (celic, modulov in nizov modulov ene vrste) za namen primerjave njihovih termičnih značilnosti, ugotavljanje NOCT (nazivne delovne temperature celic) in prevajanje izmerjenih značilnosti I-V v druge temperature.
Ta standard velja za linerane naprave z logaritemsko odvisnostjo VOC od sevanja in za stabilne pogoje. Lahko se uporablja pri vseh tehnologijah, vendar je treba preveriti, da ni učinka kondicioniranja, ki bi vplival na meritev.
