In order to write down as volt-ampere characteristic, load resistance coefficients R out is different from from 0 to very large resistance coefficient, because indefinite resistor.0 load resistance coefficient means when the volt-ampere characteristic test point that write down is for short circuit and records.In this case, tested photovoltaic concentrator module 26 does not have output voltage, and output current Iout is infinitely great, and the short-circuit current Isc that corresponding tested photovoltaic concentrator module 26 provides is also for infinitely great.
The value of pull-up resistor Rout has increased, and the about 0A of corresponding output current Iout is a standard.The Uout respective value of pull-up resistor Rout during with 0A tested photovoltaic concentrator module 26 open circuit voltages conform to.
When the value of pull-up resistor Rout increases since 0, the fixed value of the current I sc value of the short circuit that records with usual mensuration accordingly usually, the load resistance coefficient of large-scale relatively arrangement is a standard.So after by output current value IMP and output voltage values UMP mxm., the value that the output current Iout of standard shows quickly falls to 0A, when pull-up resistor Rout resistance further increases.In habitually describing, test component 1 makes the accurate volt-ampere characteristic of the photovoltaic concentrator module 26 that before general assembly record is tested become possibility, can guarantee reliable quality like this.
The volt-ampere characteristic of initial state record after be used as the control reference on identical point with the same corresponding characteristic of photovoltaic concentrator module.The difference of initial characteristic is used as the standard of the mode of operation of an evaluation photovoltaic concentrator module.This make accurately judge assembly whether continue reliable and effectively running or assembly must change and become possibility, increased the functional reliability of the installment work of this assembly.
Shown in Figure 9 before general assembly the skeleton diagram of the current voltage characteristic of different photovoltaic concentrator modules, value I1SC, I1MP, the U1MP of figure center line 110 expressions first photovoltaic concentrator module, value I2SC, I2MP and the U2MP of line 120 another photovoltaic concentrator modules of expression.
