PV Module Testing Services
Supreme Solsun Energy (Pvt) Ltd. Offering highest quality lab testing services meeting international standards. Our in-house testing lab consists of equipment from PASAN SA – Switzerland who is renowned for their outstanding accuracy and reliability and being used by leading certification institutes as well as manufacturers of solar cells & PV Modules.
1- Electroluminescence (EL) testing
When current passes through PV cells, light emission occurs. This phenomenon is called Electroluminescence. Testing of modules using this phenomenon can detect hidden defects in the structure of PV cells. This method makes the current distribution visible in the PV module and helps detect defects.
With the help of an EL test, a PV manufacturer can evaluate the structural quality of the PV cells or any other defects generated while handling.
Defects that can be found from EL are as given below:
- Microcracks
- Cell cracks
- Soldering defects
- PID defects
- Diode failure
- Dead cell
- Back sheet scratches
- Wafer defects
2- Sun Simulator Test
A solar simulator (also artificial sun or sunlight simulator) is a device that provides illumination approximating natural sunlight. The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions.
3- High Voltage Test
High Voltage Test is conducted for photovoltaic module safety testing to identify modules with the potential for leaking hazardous electrical currents when modules are installed in the field.
