Existing I-V tester: be applied in photovoltaic cell field tests, mainly under international standard required standard condition, the electrical property of test light photovoltaic assembly, obtains the peak power output of every photovoltaic module, and this test result can be approved customer, manufacturer and authenticating party.
There are 3 indexs about the classification of I-V tester, Spectral matching, irradiation non-uniformity and illumination unsteadiness.
Standard grading is as follows:
The maximum power that standard-required photovoltaic module factory can be used B level and B and above tester just can test photovoltaic cell.Irradiation non-uniformity computing formula:
In order to make test result accurate, buying back new equipment and just need to check 3 indexs at set intervals, one of them is the inspection of irradiation non-uniformity, existing method of testing is mainly that the surface that is close to photovoltaic module is tested, as shown in Figure 1, on a cross bar, be fixed with an I-V tester, because the cell piece in photovoltaic module is that matrix is arranged, therefore, in whole test process, only tester need be realized to the movement in horizontal or vertical direction, can realize each cell piece is tested.Therefore, be fixed on I-V tester 2 ＇ on cross bar 1 ＇, moving up and down to realize in different test points and test by cross bar 1 ＇, described cross bar 1 ＇ two ends and support 3 ＇ are bolted, and take off bolt when line feed, complete the rear inserting bolt of line feed, each line feed all will be done installation again, line feed process is cumbersome, and line feed also must ensure tester and photovoltaic module surface keeping parallelism at every turn, makes the radiation source energy vertical irradiation of tester in tested cell piece surface.
But, due to cross bar, 1 ＇ easily stirs in the time moving horizontally or vertically enter a new line, cause the radiation source of tester to occur larger fluctuation apart from the size on photovoltaic module surface, while causing the light of radiation source and perpendicular to cell piece surface, time and favour cell piece surface, cause result of the test inaccurate.Because the test point of test and the relative position of battery not quite identical, can increase the impact of the inhomogeneities of human error on light intensity each time.
