Solar photovoltaic industry MES system solution

Due to the increasing energy crisis and people’s increasing awareness of environmental protection, the global solar photovoltaic industry has developed rapidly. With the rise of world-class photovoltaic companies represented by Suntech’s Suntech, China’s photovoltaic manufacturing capacity has also been rapidly Ascension has become the world's largest solar cell producer.

After several years of continuous significant increase in production capacity, many leading companies in the solar industry have begun to realize the importance of quality management, but they suffer from the lack of a comprehensive quality control system, the lack of systems for collecting information production data, and the lack of manufacturing. Information base to support the quality control department to determine and monitor product quality.

The main products of the solar photovoltaic industry include the production and processing of silicon ingots, silicon wafers, solar cells, and battery modules, and the implementation of ancillary projects. Due to the complexity and particularity of the solar photovoltaic industry itself, most products need to be exported. The requirements for product quality and traceability are extremely high, which determines the demand for automated control and highly information-based integration of production sites in the solar photovoltaic industry.

Open Database (Open DataBase)

EAS-MES solar energy industry system can integrate management functions such as production scheduling, product tracking, quality control, equipment failure analysis, and network reports on a unified platform. It can use a unified database and can also be a production department, a quality inspection department, and a process department. Logistics departments provide workshop management information services.

EAS-MES PV production execution system helps customers to clearly understand all production process information of each batch of products, and immediately identify its raw material suppliers, operating machines, operating personnel, processes, production time and date, and can eliminate manual reports. , Automatically count the production quantity, qualification rate and defect code of each process.

Seamless integration between chips, sensors and equipment (such as string welding, lamination, curing, testing, binning, etc.) is achieved through automated integration technology, and key process parameters in the production process are collected to assist customers in the product The quality inspection data is automatically counted and analyzed, and the random fluctuation and abnormal fluctuation of the product quality are accurately distinguished, and the quality risk is eliminated in the bud;

Solar MES System Implementation Benefits

The purpose of the development of solar cell manufacturing equipment is to improve the final product quality of the battery, photoelectric conversion efficiency and the entire line production efficiency, while reducing production costs. Therefore, implementation of the EAS-MES solar photovoltaic industry management system will bring the following changes to the company:

1. Improve the automation level of single machine, increase the amount of batch loading, and increase the production efficiency of stand-alone machines.

2. Various costs (quality cost, management cost, material cost) are reduced by 15-30%, and production efficiency is increased by 55%.

3. Materialize more advanced technology into the equipment, further improve the photoelectric conversion efficiency of solar cells, reduce the cost per watt, automatically transfer equipment, detect online, improve overall production efficiency, reduce manual intervention, and reduce the fragmentation rate.

4. Through the implementation of the MES system, all production control links are implemented with standardized coding controls. All information is well documented and available, and all kinds of confusion are unclear.

5. MES provided all personnel with a platform and tools for full traceability. Any problems related to production, quality, and equipment can be directly traced back to specific workshops, production lines, processes, individuals, time, processing results, and processing methods through the MES system. Such as a series of information, which invisible to all levels of staff, has produced a great spur and promotion.
