BR-PV-UV-Preconditioning (UV resistance) Tester
The plan is specially designed UV ageing proof box by BV company for the photovoltaic industry. Refer to IEC 61215-2005、IEC 61730-2004、IEC 61345-1998《UV test PV modules》national standards , design notes are as follows :
1. PV modules materials and UV test principle
In the use of polymer materials often appeared in the process of the powder, discoloration, foaming, crack, shedding phenomenon, which has seriously affected the appearance of products, and other aspects of performance.
Therefore, the need to understand the polymer materials-aging mechanism and the search for a suitable artificial accelerated aging test-objective approach to simulate natural conditions, so as to the development and application of materials to provide rapid detection and evaluation of the quality of the basis.
Currently used artificial accelerated aging test method main xenon lamp, ultraviolet fluorescent lamps, metal lamps, and carbon arc lights etc.. The backplane materials (composite membrane) general we seek to reduce heat absorption, and effectively prevent excessive battery temperature increase reduces component / battery conversion rate, but xenon light source (280 to 3000 nm) in the infrared spectrum easily lead to the absorption of heat components, the components used UV weatherable performance test.
The B.R. company developed BR-PV-UV PV modules UV-testing machine dedicated to the PV modules resistant to climate experiment.
2. IEC 61215 UV-Pretreatment test conditions
1. Purpose
To precondition the module with ultra-violet (UV) radiation before the thermal cycle/humidity freeze tests to identify those materials and adhesive bonds that are susceptible to UV degradation.
2. Apparatus
a)Equipment to control the temperature of the module while it is irradiated by UV light. The equipment must be capable of maintaining the module temperature at 60℃ ±5℃.
b)Means for measuring and recording the temperature of the module(s) to an accuracy of while it is irradiated by UV light ±2℃.Te temperature sensors shall be attached to the front or back surface of the module near the middle. If more than one module is tested simultaneously, it will suffice to monitor the temperature of one representative sample.
c)instrumentation capable of producing of measuring the irradiation of the UV light produced by the UV light source at the test plane of the module(s),within the wavelength ranges of 280 nm to 320 nm and 320 nm to 385 nm with an uncertainly of ±15%
d)A UV light source capable of producing UV irradiation with an irradiance uniformity of ±15% over the test plane of the module(s),with no appreciable in the different spectral regions of interest as defined in 10.10.3
3. Procedure
a)Using the calibrated radiometer measure the irradiance at the proposed module test plane and assure that at wavelengths between 280 nm and 385 nm it has a uniformity of ±15% over the test plane
b)Mount an open-circuited module in the test plane at the location selected in a), normal to the UV irradiance beam. Make sure that the module temperature is ±5℃.
c)Subject the module(s) to a total UV irradiation of 15kwh.m-2 in the wavelength range between 280 nm and 385 nm, with at least 5 kwh.m-2 in the wavelength band between280 nm and 320 nm, while maintaining the module temperature within the prescribed range.
4. Final measurements
Repeat the test of 10.1, 10.2 and 10.3
5. Requirements
The requirements are as follows:
No evidence of major visual defects, as defined in clause 7;
The degradation of maximum output power shall not exceed 5% of the value measured before the test Insulation resistance shall meet the same requirements as for the initial measurements.
3. Instrument description
Reference IEC 61215-2005, IEC 61345-1998, and GB/T 19394-2003 "photovoltaic (PV) components UV test" corresponding standard clauses, which instrument was designed and manufactured, and technology indicators in the programme book for this technology.
