  • Quality control

We transport our solar cells with great care and implement strict transport control on our transporters. We also regularly test our solar cells for defects by carrying out random checks; this way we can be certain that the cells we deliver will provide the result that can always be expected from us. Our cells are tested by way of a flash test and electroluminescence. These quality checks are done by SolarTester, an independent party, on location.

Flash Test: Determination of nominal power to standard testing conditions (STC). The nominal power is determined by the current and voltage measured from the solar cell during the light flash, with a maximum light intensity of 1,000 Watt/m². A current-voltage graph (IV curve) comes from this measurement. This graph determines the point at which the solar panel supplies the maximum power. This capacity is the nominal (STC) capacity.

The SolarTester Flash tester has an A-classification and measurement accuracy of +5%.

Electroluminescence. Research into invisible damage that has a negative effect on the life of the cell. When light hits the solar cell, it produces power. The reverse is also true; when you send power through the solar cell, it will emit light. By using cameras that are sensitive to infrared light, this light can be recorded. The invisible cracks and fractures in cells and other hidden defects are made visible.
