Strict Quality Control System

Reliable quality is the first priority in Sonnex module production. We are applying the highest quality standard and the most stringent quality control process for our products. Only verified raw materials by Sonnex QC team will be used on our modules. The production of each and every module is controlled through our monitoring system;  this is your best guard against potential quality risks. To ensure the reliability of modules, Sonnex engineers test on incoming components and raw materials, equipment calibration, temperature and run-through time during production, PID, aging, mechanical loading of modules etc. 

More Reliable Warranty

By innovative design, engineering and quality control on solar modules, Sonnex provides up to 20 years product warranty and 30 years power warranty to provide more value for our customers. As the development of module technology, module power and size keeps changing, Sonnex also provides a strategic stock of spare modules . In our opinion, this is the most reliable way to fulfill the warranty obligations. With the support from our branches, offices and partners in different markets, we can react rapidly and guarantee a decent after sales service.
