PSE has introduced its new mechanical load test stand for the more realistic and comprehensive determination of mechanical stress from wind and snow loads.
Problem
Today’s standards require the determination of the effects of wind and snow loads on PV modules. The load tests are normally performed at room temperature with the module mounted horizontally and the artificial force acting vertically to the module. As snow loads do not occur at room temperature and wind does not affect vertically on the modules, these tests do not simulate the real stresses which occur in the field.
Solution
PSE developed a test stand which is able to test both non horizontal loads and loads at high and low temperature. The usage of high-tech components now offers the possibility to test loads of up to 10.000 Pa in a climate chamber from 80°C down to -40°C. The non-vertical application of force is realized through suction cup holders with angular adjustment.
Applications
All kinds of module testing according to IEC 61215 and IEC 61646 as well as solar thermal standards.
Platform
The standard size of the test stand is 2250 mm x 1500 mm with 24 pneumatic cylinders for an even load distribution. In order to shorten the set up time, all cylinders can jointly be adjusted to different module sizes. PSE offers a variety of options for enhanced testing.
Availability
Currently available.
