ultraviolet (UV) radiation UV exposure aging test chambers for pv
modules lab
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
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 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:
