Abstract

Sposób określania maksymalnej mocy przyrządu fotowoltaicznego, zwłaszcza w systemie pomiarowym, polega na tym, że dokonuje się pomiaru napięcia (U0) jałowego jednego lub więcej ogniw fotowoltaicznych wchodzących w skład przyrządu fotowoltaicznego, które pracują w stanie biegu jałowego, oraz dokonuje się pomiaru prądu (Iz) zwarcia jednego lub więcej ogniw fotowoltaicznych wchodzących w skład przyrządu fotowoltaicznego, które pracują w stanie zwarcia, z kolei dokonuje się obliczenia maksymalnej mocy przyrządu fotowoltaicznego jako iloczynu trzech parametrów: zmierzonego napięcia (U0) jałowego, zmierzonego prądu (Iz) zwarcia oraz współczynnika (k) będącego funkcją napięcia (U0) jałowego i prądu (Iz) zwarcia w postaci podanej zależności: k=a+b*U0+c*Iz+d/Iz, przy czym stałe (a), (b), (c), (d) są liczbami rzeczywistymi, które są wielkościami charakterystycznymi dla konkretnego typu i konfiguracji połączeń ogniw przyrządu fotowoltaicznego.The method of determining the maximum power of a photovoltaic device, especially in a measurement system, consists in measuring the open-circuit voltage (U0) of one or more photovoltaic cells in the no-load photovoltaic instrument, and measuring the current (Iz ) short-circuit of one or more photovoltaic cells included in the photovoltaic device, which operate in the short-circuit state, in turn, the maximum power of the photovoltaic device is calculated as the product of three parameters: measured open-circuit voltage (U0), measured short-circuit current (Iz) and factor (k ) which is a function of open-circuit voltage (U0) and short-circuit current (Iz) in the form of the following relationship: k = a + b * U0 + c * Iz + d / Iz, with constants (a), (b), (c), (d) are real numbers, which are characteristic quantities for a specific type and configuration of cell connections of a photovoltaic device.
