Inspection solutions for solar modules


  • Increased output: Achieve maximum yield with fully exploited production potential
  • Saved resources: Optimum use of material, equipment, and engineering times
  • Maximum process transparency: Anticipate process weaknesses at the earliest possible

Modules

Reduce your production costs and make sure that the modules you produce are of outstanding quality.

To achieve this outstanding quality, the raw materials have to be right. Our inspection solutions for incoming cells, thin film, foil, or solar glass detect the smallest defects and faulty material. Subsequent removal saves valuable production capacity.

Cloud-based data management reduces set-up workload and significantly accelerates commissioning and recipe adjustments. 

Our modules solutions are powered by our brand:

product branding

Incoming cell inspection & classification

final cell sorting

Identifying faulty cells before the stringer saves valuable module production capacity. CELL-Q identifies faulty cells in time and monitors their performance class. Damage caused by transporting and handling can be claimed and rectified.

Benefits

Save money: Reclaim poor cells to the supplier

Achieve homogenous modules regarding color and performance

Lowest overkill and underkill rates

PL String Inspection

Col q pl string inspection modules

Strings are the backbone of solar modules, and ensuring their quality is paramount. Photoluminescence (PL) inspection for the stringer ensures that only high-quality strings make it into the final assembly.

This cutting-edge technique employs the power of light to uncover imperfections and elevate the quality of photovoltaic strings.

At its core, PL inspection involves illuminating the cells with specific wavelengths of light, stimulating the emission of photons. This emitted light, when carefully analyzed, provides critical information about the string's material integrity and electrical characteristics. ISRA VISION’s PL inspection systems run laser-free, which reduces safety requirements.

Benefits

Quickly identify stringing problems

Integration directly into stringer outlet

No separate EL inspection station needed

Insection on-the-fly during string feedout
