UV Aging Test Chambe for PV Module 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
UV Aging Test chamber for pv module apparatus
1.A temperature -controlled test chamber with a window or fixtures
for a UV light source and the module under test. The chamber shall
be capable of maintaining the module temperature at 60±5ºC
2.A means for monitoring the temperature of the module to an
accuracy of ±2.0ºC and repeatability of ±0.5ºC. the temperature
sensors shall be attached to the front or back surface of the
module near the middle without obstructing any of the UV light
incident on the active cells within the module. If more than one
module is tested simultaneously, it will suffice to monitor the
temperature of one representative sample
3.Instrumentation capable of measuring the irradiance of the UV light produced by the UV light source at the test plane of the module, within the wavelength ranges of 280nm to 320nm and 320nm to 400nm with an unceratinly of ±15% or better
4.A UV light source capable of producing UV radiation with an irradiance uniformity of ±15% over the test plane of the module with no appreciable irradiance at wavelengths below 280nm and capable of providing the necessary total irradiance in the different spectral regions of interest
5.For light sources with a negligible spectral content in the
visible range the module shall be short circuited. Alternatively
the module can be connected to a load sized such that the module
will operate near the maximum power point . the latter is
recommended for light sources emitting a significant portion of
light in the visible spectrum where the module exhibits a power
equal to or large than20% of its STC measured power
UV aging test chamber procudrue
1.Using the calibrated radiometer measure the irradiance at
proposed module test plane and ensure that at wavelengths between
280nm and 400nm it does not exceed 250w/m2 (i.e. about five times
the natural sunlight level) and that it has a uniformity of ±15%
over the test plane
2.Short-cicuit or attach the resistive load to the module and mount it in the test plane at the location selected in a 1), normal to the UV irradiance beam , make sure that the module temperature sensors read 60±5ºC
3.Subject the module front side to a total UV irradiation of at least 15KW/m2 in the wavelength range between 280nm and 400nm with at least 3% , but not more than 10% in the wavelength and between 280nm and 320nm ,while maintaining the module temperature within the prescribed range

Product Description
uv irradiation chambers can simulate the sun, rain and dew to
damage the material,the machine using UV lamp simulate the effect
of sunlight, cold rain and dew. Being tested materials are placed
in a certain environment which the light and moisture are
alternating. The materials are tested for several days or weeks,
you can know the damage of material at outside for several months
or several years, Damage types include: bleaching, discoloration,
loss of light, powder, crack, turbidity, bubble-based,
embrittlement, strength decline and oxidation.
Corresponding standard:
Accord with ASTMG53-77, GB,GJB,MIL,ASTM,CNS,IEC,JIS,AATCC,DIN,Fed
Test,BS,SAE
Applicable industries:
accelerated weather tests is widely used in paint, resins,
plastics, printing and packaging,aluminum, adhesives, auto,
cosmetics, metals, electronics, electroplating, medicine, etc.
