We go the crucial extra mile – for extraordinary quality.
When it comes to the quality of our solar modules, we make no compromises: in addition to independent test procedures, the modules are also subjected to many intensive tests while still in the Centrosolar Sonnenstromfabrik. Our specialists leave nothing to chance, and test the modules and solar cells both during and after production. All tests are carried out at random to ensure that any module or solar cell from our production line may be tested for its capacity, workmanship or overall quality.
This test procedure tests the embedded material in the module and gives reliable information about module stability and durability.
Hot water test
The hot water test was first developed by Centrosolar. In this test, the solar cell is exposed to water heated to approx. 70° C for a long period of time. This tests to see if the aluminium alloys on the rear of the solar cell begin to loosen from the solar cell under the influence of moisture. The test, which was first developed by the Centrosolar Research and Innovation Department, initially bore the name of its inventory, Erik Eikelboom. It has since become one of the standard test procedures for solar cells, and is in regular use by many companies in the photovoltaics field.
Electroluminescence (EL) test
The recently developed EL test makes it possible to detect even marginal damage to a module using a procedure similar to the production of an x-ray image. The test indicates areas of a cell where power flows and shows the efficiency at which the tested solar cell operates. Even microspcopic defects may be reliably established using this test.
Mechanical load test (ML test)
During the test, the module is clamped in place and subjected to a variable push and pull load to simulate the effect of snow and wind on the module.
Climate chamber test
The climate chamber is capable of recreating, in a controlled environment, the climatic conditions to which a solar panel is exposed over changing seasons. Several tests facilitate a reliable forecast of the probable life expectancy of a module and its performance.
The peel test is a measurement procedure which tests the quality of the soldered connections in a module under dynamic load conditions. It is carried out during running production so as to be able to eliminate weak points at cells or cell connectors at the earliest possible point.
