PV Module

Our Products

Solar photovoltaic (pv) modules generate electricity from sunlight, which can be fed into the mains electricity supply of a building or sold to the public electricity grid. Reducing the need for fossil fuel generation, the growing grid-connected solar PV sector across the globe is helping create jobs, enabling families and businesses to save money, and cut greenhouse emissions.

Quality Control Systems

The quality system is followed in 4 sections in Insolation energy:

  • Incoming Quality Inspection (IQC)
  • In process Quality Inspection (IPQC)
  • Final Quality Inspection (FQA)


All raw materials are inspected as per Quality Plan of Insolation enegy.

The materials are checked for dimensions, Specifications, Quantity, weight,shelf life visual as per criteria laid out in Quality Plan of material. The following material are inspected whenever they arrive in the plant as per criteria laid out in Quality Plan: EVA, Glass, Cell, Backsheet, Ribbon, Busbar, Frame, Junction box, silicon Sealant, Labels, Packing Boxes, wooden pallets IN PROCESS QUALITY INSPECTION The product during manufacturing is inspected at various stages on line for various parameters as per criteria laid out in Quality Plan.
These are the stringent inspections performed at various stages so that product produces if of Premium Quality. The following inspections are performed on Product during manufacturing as per Quality Plan:

  • Visual Glass Inspection for Spots, transimission etc
  • Cell Testing with reference of calibrated cells
  • Visual inspection of cells
  • EVA and backsheet for dimensions
  • Ribbon Pull Test-peel strength
  • Gap between Cells
  • Gap between strings
  • Gap between cells and Glass side edge
  • Gap between cells and Glass top edge
  • String Polarity
  • Bus Bar Location w.r.t. Junction box terminal
  • IV testing at Lay up
  • EL test before Lamination and after lamination
  • Visual Inspection before & after Laminator
  • Gap between Bus bars
  • Gap between Busbar and cells
  • Visual Inspection after Lamination
  • Frame Inspection after fitment
  • Junction Box Assembly and pull test Inspection
  • Electrical Parameters of Modules
  • Leakage current at high voltage
  • IR at high voltage –HIliOT test
  • Wet leakage test
  • Module visual Inspection
  • Packing Inspection
  • Gel content Test
  • Back sheet Pull test
  • Sun shocking- R&R
  • Damp heat test*
  • Partial discharge test *


The Product is inspected before dispatch to customers for visual inspection, packing and electrical parameters. After stringent Quality inspection solar modules are dispatched to customers.


The sun simulator and High Voltage equipment are calibrated in every shift so that machine performs all the testing in accurate manner and product is of specified parameters.
