Environmental Chambers for Solar Panel Testing
Our chambers are solid, one-piece construction, using fibreglass insulation and an angle-iron frame. The stainless steel interior liner is reinforced and continuously welded, including leak-testing for integrity.
The angle-iron frame provides enough structural strength to allow a full-opening door for easy loading of large arrays without restriction. A full-opening door can also allow floor-space saving over panel chambers.
Our chambers are compliant for the following test methods: Thermal Cycle Test
Requires temperature cycling between 85°C and -40°C, 50 or 200 times
Humidity Freeze Test
Cycling between hot/humid 85°C/85%rh and subfreezing -40°C ten times, with extended soaks at 85/85
Damp Heat Test
A long term, 1,000 hours, test at 85°C/85%
ESPEC chamber for Damp Heat Testing only is also available.
