The production line
From cell to module, every step is controlled.
Automation handles the repetition. Our people handle the judgement. Checks sit between the stages, not only at the end.
- Incoming inspectionCells, glass and encapsulant checked before they reach the line.
- Cell stringingHalf-cells soldered into strings on multi-busbar stringers.
- LayupRobotic placement of strings on glass and encapsulant.
- Bussing & pre-lamination ELStrings interconnected and imaged before the laminate is closed.
- LaminationHeat and vacuum bond the stack into one weather-tight laminate.
- Framing & junction boxAnodised frame, sealant and IP68 junction box fitted.
- Flash test & final ELEvery module power-classed and imaged again.
- Packing & dispatchLabelled, packed and documented under your brand.
Quality checks
Tested before it leaves Vapi.
Every module passes through the same sequence of checks, so a module in your warehouse behaves like the one you approved.
Flash testing
Each module is measured under a calibrated flash to confirm its power class before it is labelled.
Insulation & hi-pot
Electrical safety checks confirm insulation integrity ahead of packing.
Visual & dimensional
Glass, frame, sealant and junction box are inspected against the approved specification.
Quality & standards
Qualified to international standards.
Our modules are tested to the IEC and BIS standards that developers, EPC partners and financiers ask for, and every module is EL-inspected and flash-tested before it leaves Vapi.
