YBOPTOTECH has 3 series of solar module products: YB-S3,YB-S4,YB-S5. and each series contains bifacial and monofacial module. YB-S3 and 54-cell type YB-S4 is mainly used on industrial, commercial and residential roofs. Both bifacial and monofaical of YB-S5 with 72-cell is mainly for large ground-mount power plants.

Bifacial modules are slightly more expensive than monofacial modules, but can generate more power under the right conditions. When the rear side of the module is not blocked, the light received by the rear side of the bifacial module can significantly improve energy yield. In addition, the glass-glass encapsulation structure of the bifacial module has better resistance to environmental erosion by water vapor, salt-air fog, etc. Monofacial modules are more suitable for installations in mountainous regions and distributed generation rooftop applications.

YBOPTOTECH took the lead in working with domestic and foreign institutions and customers to carry out empirical testing of bifacial modules for PV power plants, systematically studying the power generation mechanisms of bifacial modules. YBOPTOTECH also leads the industry in bifacial module shipments, surpassing 20 GW+, while providing customers with reference data and technical support.

YBOPTOTECH has the largest module production capacity in the industry, with more than 65 GW in its integrated capacity network fully guaranteeing the supply of modules. In addition, the production network facilitates the global distribution of modules with the help of land transportation, railway transportation and sea transportation.

YBOPTOTECH launched Life-cycle Standards to guarantee the whole life-cycel quality.YBOPTOTECH’s Integrated capacity layout can guarantee the traceability of each module, and our highly automated production lines feature end-to-end inspection and analysis processes to ensure that each module meets the highest quality standards. We select module materials according to the highest standards, with the requirement that all new materials be subject to extended qualification and reliability tests before being incorporated into our products. Third-party labs like RETC and PVEL have ranked our modules among the highest quality products on the market.
