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:

PL String Inspection

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 system LUMI-Q Scan runs laser-free, which reduces safety requirements.

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