Our products are continuously improved through innovative research methods
Every product we offer is carefully inspected for quality. During the manufacturing process, each cell is tested to detect invisible micro-cracks, so we can guarantee that only the highest quality panel will be on your roof.
The modules we offer double the IEC test standards.

| PID (voltage induced degradation) tests PID checks are performed to test resistance to the degradation phenomenon that causes damage to modules in the long term. This phenomenon occurs when low-quality modules are used. SOLSUM offers modules free of the PID phenomenon. |
Hot water test In this test, the cells are immersed in water heated to about 70°C for an extended period of time. The test demonstrates whether the aluminum alloys in the back of the cell de-laminate when exposed to moisture. |

| Link tests This test checks the module’s built-in link connections and gives reliable information on the module’s stability and strength over time. |
Mechanical load test During this test, the module is subjected to varying loads to simulate snow and wind loads on the PV module. |

| Electroluminescence test A recently developed method to detect even trace damage to a module using a technique similar to taking an X-ray. The test indicates areas of the cells where there are microcracks that are undetectable to the naked eye. |
Tests in a climate chamber The climate chamber is capable of reproducing, in a controlled environment, the climatic conditions to which the module is exposed under operating conditions during the change of seasons. Numerous tests facilitate a reliable prediction of the module’s lifetime and performance quality. |
