23、 and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates, as defined in IEC 60721-2-1. It applies only to crystalline silicon modules types. A standard for thin-film modules has been published as IEC 61646. This standard does not apply to m
24、odules used with concentrated sunlight. The object of this test sequence is to determine the electrical and thermal characteristics of the module and to show, as far as is possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in climat
25、es described in the scope. The actual lifetime expectancy of modules so qualified will depend on their design, their environment and the conditions under which they are operated. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、lification testing (plus spares as desired) shall be taken at random from a production batch or batches, in accordance with the procedure given in IEC 60410. The modules shall have been manufactured from specified materials and components in accordance with the relevant drawings and process sheets a
33、nd have been subjected to the manufacturers normal inspection, quality control and production acceptance procedures. The modules shall be complete in every detail and shall be accompanied by the manufacturers handling, mounting and connection instructions, including the maximum permissible system vo
34、ltage. If the bypass diodes are not accessible in the standard modules, a special sample can be prepared for the bypass diode thermal test (10.18). The bypass diode should be mounted physically as it would be in a standard module, with a thermal sensor placed on the diode as required in 10.18.2. Thi
35、s sample does not have to go through the other tests in the sequence depicted in Figure 1.When the modules to be tested are prototypes of a new design and not from production, this fact shall be noted in the test report (see Clause 8). 4 Marking Each module shall carry the following clear and indeli
36、ble markings: name, monogram or symbol of manufacturer; type or model number; serial number; polarity of terminals or leads (colour coding is permissible); maximum system voltage for which the module is suitable. The date and place of manufacture shall be marked on the module or be traceable from th
37、e serial number. _1Under consideration. EN 61215:2005 7 5 Testing Before beginning the testing, all modules, including the control, shall be exposed to sunlight (either real or simulated) to an irradiation level of 5 kWhm2to 5,5 kWhm2while open-circuited. The modules shall be divided into groups and
38、 subjected to the qualification test sequences in Figure 1, carried out in the order laid down. Each box refers to the corresponding subclause in this standard. Test procedures and severities, including initial and final measurements where necessary, are detailed in Clause 10. NOTE 1 Where the final
39、 measurements for one test serve as the initial measurements for the next test in the sequence, they need not be repeated. In these cases, the initial measurements are omitted from the test. In carrying out the tests, the tester shall strictly observe the manufacturers handling, mounting and connect
40、ion instructions. Tests given in 10.4, 10.5, 10.6 and 10.7 may be omitted if future IEC 61853 has been or is scheduled to be run on this module type. Test conditions are summarized in Table 1. NOTE 2 The test levels in Table 1 are the minimum levels required for qualification. If the laboratory and
41、the module manufacturer agree, the tests may be performed with increased severities. 6 Pass criteria A module design shall be judged to have passed the qualification tests, and therefore to be IEC type approved, if each test sample meets all the following criteria: a) the degradation of maximum outp
42、ut power does not exceed the prescribed limit after each test nor 8 % after each test sequence; b) no sample has exhibited any open circuit during the tests; c) there is no visual evidence of a major defect, as defined in Clause 7; d) the insulation test requirements are met after the tests; e) the
43、wet leakage current test requirements are met at the beginning and the end of each sequence and after the damp heat test; f) specific requirements of the individual tests are met. If two or more modules do not meet these test criteria, the design shall be deemed not to have met the qualification req
44、uirements. Should one module fail any test, another two modules meeting the requirements of Clause 3 shall be subjected to the whole of the relevant test sequence from the beginning. If one or both of these modules also fail, the design shall be deemed not to have met the qualification requirements.
45、 If, however, both modules pass the test sequence, the design shall be judged to have met the qualification requirements. 7 Major visual defects For the purposes of design qualification and type approval, the following are considered to be major visual defects: a) broken, cracked, or torn external s
46、urfaces, including superstrates, substrates, frames and junction boxes; EN 61215:2005 8 b) bent or misaligned external surfaces, including superstrates, substrates, frames and junction boxes to the extent that the installation and/or operation of the module would be impaired. c) a crack in a cell th
47、e propagation of which could remove more than 10 % of that cells area from the electrical circuit of the module; d) bubbles or delaminations forming a continuous path between any part of the electrical circuit and the edge of the module; e) loss of mechanical integrity, to the extent that the instal
48、lation and/or operation of the module would be impaired. 8 Report Following type approval, a certified report of the qualification tests, with measured performance characteristics and details of any failures and re-tests, shall be prepared by the test agency in accordance with ISO/IEC 17025. The rep
49、ort shall contain the detail specification for the module. Each certificate or test report shall include at least the following information: a) a title; b) name and address of the test laboratory and location where the tests were carried out; c) unique identification of the certification or report and of each page; d) name and address of client, where appropriate; e) description and identification of the item tested; f) characterization a
