Overview

KOMEG large walk-in chamber is suitable for batches of small samples or large parts of the whole machine, simulating temperature, humidity and other climatic conditions that will affect the performance and life of the product.

Product Details

Specialized Chambers for Solar Panel Tests

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 hour, test at 85°C/85%.

Environmental Chambers for Solar Panel Testing (Walk-in Type)

Specialized Chambers for Solar Panel Tests

From compact type to large type, which can test a lot of full-size PV modules at one time, KOMEG provides various sizes of Solar Panel Walk-in Chambers.

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
