Manufacturing Facility

Tabber & Stringer
This is the cell assembly process which is done by soldering. It is crucial to maintain an accurate soldering time and soldering temperature that shall determine the durability of the cells.

Lamination process
In this stage of the process, all the components of the PV panel are placed on top of each other like a sandwich. They are then pressed to one piece. Then, the panels are sent to the framing area.  SRS is the first in World, to develop own Multi-stack Laminator. This process is crucial in the performance of the PV modules, enabling us to provide 25 years of service guarantee and performance warranty.

Framing 
After the lamination process, the excess parts of the compressed panels are cut out and taped on all sides. The framing machine then fixes the frame for the modules on all four adjacent sides.

Flashing 
The junction box is attached to the panel and then sent to the flashing section. The flasher measures the output produced by each panel; this is an in-line testing process that is done for 100% for-every single module. The qualified panels are then packed as per their grade and sent to the storage facility.

High voltage testing
The amount of leakage current in each of the modules is measured in this high-voltage testing process by applying 4,800 volts of current to the modules. The leakage current produced by the module should be less than 50 amps as per ISE regulations.

Insulation resistance testing 
The electrical safety between the PV module and the external environment is examined in this process. Up to 1500 volts of current is applied on the modules for this process and as per the regulations, the resistance of the module should be above 40 megawatts.

Electroluminescence testing 
The health of the module is identified through this test, which identifies micro-cracks that may be present in the modules and are not visible to the naked eye.

Mechanical load test 
Checks the mechanical stability of the module that ensures that the modules are capable of withstanding harsh weather conditions. 5,400 pascals of the load is applied to the modules for one hour and then the power output degradation is tested. The module is considered reliable when its power degradation is less than 5%.

Wet leakage test 
The performance of the modules in wet conditions is identified here. For this, the modules will be immersed in water and up to 1500 volts of current will be passed through the water to determine the power leakage in similar conditions.
