lightway-solar-cell-inspectionLight Way Solar’s Exceptional Quality: From Ingot To Wafer To Cell To Module

As a PV manufacturer with one of the world’s leading integrated production lines, Light Way always keeps pace with the developing global standards for PV products, and works to continuously improve the technology and efficiency of their processes.

Lightway’s fully integrated value chain of multicrystalline silicon wafers, solar cells, and solar modules gives them the ability to improve every small detail and closely monitor quality throughout the entire process.

Here’s how the vertically-integrated production process works…

light-way-solar-ingotStep 1: Silicon Ingot:
LightWay use advanced heat exchange ingot furnaces with directional solidification technology.

By heating the silicon uniformly with infrared radiation and controlling the temperature variation, the resulting polysilicon ingot is aligned in the most favorable direction.

lightway-solar-waferStep 2: Silicon Wafer:
LightWay employs the world’s leading saw blade equipment with multi-wire cutting technology.

This enables them to produce high quality silicon wafers with flat and even surfaces, uniform thickness, no cracking and minimal waste.

Thanks to their top of the line equipment, coupled with advanced testing processes, only the highest quality wafers pass through to Light Way’s cell production phase.

lightway-solar-cellsStep 3: Solar Cell
Light Way’s advanced diffusion technology ensures uniformity in the diffusion process; high-quality wet etching equipment and etching processes increase the parallel resistance and improve the performance of the cell; advanced PECVD filming technology is utilized to produce a dark blue antireflection film that reduces the reflection rate; advanced net printing technology and high quality metal pulp produces the background field and electrode, ensuring high quality and efficiency of the cells.

Once Lightway has produced the high-performance solar cells, they are assembled into premium Lightway solar panels.

Hardened, high-transparency glass protects the cells from the extremes oif Australia’s weather, and the whole module is framed in tough, anodised, 50mm aluminium to ensure long life.

Superior performance is provided by the use of 3 Bus Bars per cell, for better low-light performance, and 6 bypass diodes per cell, to ensure optimum energy return in shaded conditions, and improved protection against hotspots.

At Every Step: Rigorous Quality Control and Testing


To ensure that every product passing through their factory to the customers is of the highest quality, Light Way have an advanced team of quality supervision officers that pay very special attention to quality control through the manufacturing process.

Every single wafer and solar cell is individually inspected and sorted in order to increasire efficiency and achieve maximum uniformity of the solar modules.

In addition to the 50 online inspection points there are 10 offline, which guarantee that no defective or unqualified products pass through to the next process. All the online inspection points are completed by very precise state of the art inspection equipment and the offline inspection points are executed by experienced officers and advanced technology.
