UV Radiation Chamber for IEC 61646 & IEC 61215

UV light radiation test is an irradiance test to discover out to which prolong solar panels are inclined to ultraviolet (UV) degradation and as a result overall performance losses. The Wewon’s UV radiation chamber for IEC 61646; IEC 61215 test standard, which is basically utilized to solar panel certification and research, is normally carried out earlier than the thermal cycle and humidity rapidly tests. The UV radiation test is carried out at a temperature of +60°C ±5°C, whilst subjected to UV irradiation (UVA + AVB and UVB).

In PV modules testing, many exclusive factors are uncovered to the sunlight. Therefore, the IEC 61215 defines a UV preconditioning test (MQT 10) to test at whether or not these elements can face up to the UV radiation of the sun. In Weson’s uv radiation chamber, the UV radiation is up to 5 times the solar depth to speed up the test, as requested in the UV preconditioning test.

During the test, the module temperature is stored steady at +60°C in a distinct temperature chamber. We supply our UV light test chamber solutions which include the records acquisition unit, radiation and temperature sensors. For waste warmness disposal, the uv chamber is geared up with a water/air warmth exchanger that can be related to a bloodless water grid. This minimizes the warmness load in the room have been the machine is installed.

With the UVB-313 and UVA-340 lamps with 100W as the light source, the uv radiation chamber for IEC testing is simulating the solar to generate the UV light, for different material persistence testing. From the temperature shut loop control, it is capable to make adjustment to the irradiance degree for stability. At the equal time, time interval is controlled.

UV Radiation Chamber for IEC 61646 & IEC 61215

The UV radiation chamber used to be designed to meet the necessities of PV module check labs, certification our bodies and lookup institutes for quick UV preconditioning check in accordance to the modern-day IEC standards.
The uv chamber can be optimized to suit from 2 up to 6 PV modules, irradiance degree is up to 250 W/m² and mild non-uniformity is higher than 15%. The temperature range is +55ºC ~ +65ºC to meet the norm requirements.
UV Test Chambers manufactured by means of Wewon Environmental Chambers Co., Ltd. simulates the solar through producing UV light for material testing.
UV irradiation doses: 15 kWh/m² for IEC 61215 and 60 kWh/m² for IEC 61730
Wewon’s gorgeous UV test chambers are made from SUS 304 stainless steel and function UV lamps life of round 1200 hours. The Intensity of the mild supply can be adjusted with the uniformity vary of +15%.
The mild supply is a 100W UV light placed at a single or each facets of the chamber at a top of 1700mm. With the pryadiometer and current managed UV lamp system, the UV lamp’s intensity can be adjusted from the stage of modern flow.
In extra to the UV check a Bypass diode check is required to get right of entry to the adequacy of the thermal format and relative long-term reliability of the skip diodes used to restrict the dangerous results of module hot-spot susceptibility.
Wewon have mixed each the UV and Bypass check into one piece of tools therefore providing their clients a vast discount in set up space.
The Wewon’s UV radiation chamber can warmth the module to a temperature of +72 °C ± 3 °C. and measure / document the temperature of the modules to an accuracy of ±1 °C. and additionally measure the junction voltage of the skip diodes to an accuracy of 0.2
Wewon grant a full set of system that additionally permits cutting-edge equal to 1.25 instances the STC brief -circuit present day of to be utilized to the module underneath check and the capability for monitoring the float of modern-day thru the module, at some point of the test.
