KOMEG Specialized Environmental Test Chambers for Solar Panel Testing (Walk-in Type)
Specialized Chambers for Solar Panel Tests
KOMEG offers a wide variety of test chambers that allow you to test per the IEC and UL requirements. We can work with you to decide which equipment has the needed size and features to suit your application.
Factors
such as desired throughput, testing methodology, floorspace, and budget will affect the final selection.
Our chambers can be used for the following test methods:
•10.11 Thermal Cycle Test
Requires temperature cycling between 85°C and -40°C,
50 or 200 times.
•10.12 Humidity Freeze Test
Cycling between hot/humid 85°C/85%RH and subfreezing -40°C ten times, with extended soaks at 85/85.
•10.13 Damp Heat Test
A long term, 1,000 hours, test at 85°C/85%.
Selecting a Chamber
Because the change rates in the specifications are
flexible, you have a choice of selecting a slower system to save cost and utilities, or a faster system to shorten testing time.
In order for KOMEG to select the proper heating/cooling subsystems, we will need to know:
• Chamber interior space required
• Total mass of modules and supporting racks to be tested
•Desired heat & cooling rates (Otherwise KOMEG will quote systems to meet both minimum or maximum rates allowed by IEC.)
Lengthy IEC and UL Tests
All three of the IEC 61215 & 61646 environmental tests KOMEG chambers are used for can be done in the same test chamber. It may be better, however, to consider multiple chambers to save time and electricity due to the lengths of the tests:
•The temperature cycling test may last up to seven weeks.
•The damp heat test is six weeks long.
•The damp heat test requires only minimal refrigeration, reducing capital and energy costs if a dedicated model is selected for this test
