21、certificates shall be listed on the data sheet. 3.2 Constructive material The descriptions of the following materials used to build the PV module are required: cell type and material; frame material; front cover type. 3.3 Electrical performance The characteristic quantities in 3.3.1 to 3.3.3 are req

22、uired. 3.3.1 P max , I sc , V ocand V mppat STC (1 000 W/m, (25 2) C, AM 1,5 according to EN 60904-3) For a-Si modules, nominal and minimum values of maximum output power at STC must also be specified. 3.3.2 P max , I sc , V ocand V mppat at 800 W/m, NOCT, AM 1,5 3.3.3 Reduction of efficiency from a

NOTE 2 NOCT (Nominal Operating C

24、ell Temperature): Module operation temperature at 800 W/m irradiance in the plane of module, air temperature 20 C, wind speed 1 m/s and open circuit condition. NOTE 3 P max : maximum electrical power; V oc : open circuit voltage (“open circuit“); I sc : short circuit current (“short circuit“); V mpp

25、 : voltage at point of maximum power (“maximum power point“). 3.4 General characteristics Specify information about the connection box such as, dimensions, IP-rating, electrical connection technique (e.g. connector or wiring): outer dimensions (length, width) of photovoltaic module, total thickness

26、of photovoltaic module, and the weight. NOTE More detailed information (e.g. mounting instructions, detailed dimension drawings, kind and thickness of front cover) is recommended. 3.5 Thermal characteristics 3.5.1 NOCT value is required. 3.5.2 Temperature coefficients (TC) in 1/K of I scand V ocare

27、required. NOTE 1 With the help of temperature coefficients “TC”, the electrical characteristic quantity “y reference” at the reference temperature “T reference” can be transformed to another operating temperature “T“: y = y reference 1 + TC (T - T reference) NOTE 2 Temperature coefficients with the

28、dimension 1/K are calculated from “determination of temperature coefficients“ EN 61215 qualification tests (no additional measurements). NOTE 3 In the case that the TC is non-linear, give more information about the TC. 3.6 Characteristic quantities for system integration Required are: 3.6.1 Design o

29、pen circuit voltage (V ocat STC), maximum permissible system voltage and protection classification. 3.6.2 Limiting reverse current I Rin A (reverse current carrying capacity) of the photovoltaic module. NOTE 1 Reverse current carrying capacity gives the maximal current for operation of photovoltaic

30、module at V V oc without permanent damages of the photovoltaic module. For operation voltages higher than open circuit voltage module, the current changes its sign. From the view of the photovoltaic module, it is then a reverse current. NOTE 2 A photovoltaic module can be operated at the limiting re

31、verse current I R (V V oc) at (60 2) C air temperature (in the dark) for eight hours without a change of maximum power P max of more than 5 % at control measurements at STC after the test. P max and V oc are the values at STC (see 3.3.1). EN 50380:2003 6 EXAMPLE Example for an experimental implement

33、 STC after 3.3.1). c) Assessment of photovoltaic module before and after each current step according to EN 61215 steps 10.1 to 10.3. d) Maximum power at STC after step “i” (current I i ) is P max,i . If P = | P max,i- P max| / P max 0,05 and P = | P max,i+1- P max| / P max 0,05, then the current I I

Therefore

35、this drawing may differ in some countries. 3.7 Power rating and production tolerances 3.7.1 Upper and lower production tolerances (in percent) for a given maximum power P maxare required. NOTE It is possible to agree minimum power values. 3.7.2 The electrical characteristic quantities according to 3

36、.3 have to be detected after pre-ageing in open circuit condition with 20 kWh/m irradiance in the plane of module and considering the measurement tolerances of the (external) test laboratory. NOTE For pre-ageing, natural sunlight or a solar simulator according to IEC 60904-9 has to be used. 7 EN 503

37、80:2003 EXAMPLE A PV module is rated with a nominal power of “P max “ of 50 watts at STC (with consideration of pre-ageing at start of operation) and production tolerances “ t” of 10 %. This module is measured in an external test laboratory with measurement tolerances “ m” of 4 %. In the unfavourabl

38、e case (lower tolerance limit), the photovoltaic module from production has an electrical power “P” of = 100 % 1 max t P P (1) In this example, P = 45 watts. In the unfavourable case (lower measurement tolerance), the external test laboratory measures the electrical power “Pmeasurement ” of = 100 %

39、1 t measuremen m P P (2) In this example, P measurement= 43,2 watts. This means in this example that a photovoltaic module, measured with 43,2 watts, agrees with the statement “Nominal power of 50 watts with production tolerances of 10 %“. 3.8 Data sheet language The data sheet shall be written in E

40、nglish and a local language. 4 Nameplate information Name and sign of origin of manufacturer or supplier, Type designation, Protection classification, Permissible maximum system voltage, P max production tolerances, I sc , V oc , V mpp(all values at STC). NOTE 1 All labels and characteristic signs a

41、re in durable construction in or at the photovoltaic module. All labels must be written in English. NOTE 2 A serial number identification containing the name of the manufacturer and the serial number must be placed in such a way it is non-removable (preferable by encapsulation and readable after ins

42、tallation). This serial number identification can be located e.g. at the edge of the photovoltaic module. It is allowed that this serial number identification is covered after installation by a frame e.g. in faade installations. NOTE 3 If it is not possible by the nature of the photovoltaic module t

43、o fix a nameplate, then it is necessary to announce the details according to Clause 4 to the user in other reliable, unambiguous and effective ways, e.g. in the accompanying documents (operating instructions, data sheets). These documents are then part of the photovoltaic module. They have to be enc

44、losed with every photovoltaic module. NOTE 4 STC must be defined as 1 000 W/m and 25 C cell temperature.
