Large Highly Accelerated Stress Test System
(HAST Chamber)

Overview of Equipment

Perform accelerated tests of solar cell modules

The solar cells used for solar power generation, which is the major player among clean energy supply sources, are exposed to a variety of different environment because they are installed outdoors. Therefore, many different types of tests are conducted for their reliability evaluation. Service life evaluation of panel modules is particularly important, and various checks ranging from analysis of causes of failure to standard tests are conducted from the development stage continuing even after the start of mass production. ESPEC supports these requirements with test systems with larger capacity.

Solar cell modules are required by the market to have a longer period warranty, and durability test periods are lengthening.
Meanwhile, from the development stage to the mass production stage, person in charge of development and evaluation are grappling with how to efficiently evaluate reliability more quickly.
Therefore, accelerating the evaluation of solar cell modules is in demand more than ever.
This system has an inside capacity of 3,300 liters to enable testing of modules.
As with the EHS-431M, EHS-221M, and EHS-411M, this model is capable of providing the pressure cooker test and unsaturated pressure cooker test, enabling standard IEC60068-2-66 testing despite its large size.

  • Shorter testing time compared to humidity tests under atmospheric pressure
  • Equipped with an advanced fan for far improvement in temperature and humidity distribution
  • Chamber diameter of 1,450 mm and a length of 2,000 mm to enable large solar module testing
  • Equipped with mechanical door lock function and door lock safety function

  • * The specifications for the wide-range HAST test, whisker accelerated test, and air HAST test will be adjusted according to the requirements of each test.
  • * The specimen power supply terminal will be offered in accordance with the specifications requested by a customer
  • * If the requirements include the application of high voltage in the test area, it might cause electrical discharge inside the area; we will make specific suggestions to customers after studying their requirements in details. Please note that we might not be able to meet this requirement if a creepage distance cannot be secured or other reasons. Thank you for your understanding.
