| A method of the p-n junction overheating temperature evaluation in PV modules operating in the maximum power point (MPP) regime has been elaborated. It does not require the specialized equipment, as well as the data on the open circuit (OC) voltage temperature coefficients measured in pulsed regime. The method consists in measuring several open circuit voltage magnitudes accompanied by temperature measurements on the external module surface near one of the cells. In the procedure, a fast transition from MPP to OC operational regime is carried out, at which a time-dependent voltage measurement is performed with the help of a memory oscilloscope. The OC voltage temperature coefficient, as well as a ?reference? OC voltage magnitude in a ?cold? module (the conditions realized at the moment after instant opening the module to the sun illumination) are determined by calculations. Therefore, mechanical shuttering the module aperture area is not necessary (a procedure, which can not be standardized). Methodological temperature evaluation accuracy is higher, if PV modules of higher conversion efficiency are tested. | |
