Bifacial dual-glass solar panels can be categorized into various types based on cell technology, structural design, and application requirements. These types differ in terms of power generation efficiency, operating environments, and costs. Common types currently on the market include P-type bifacial dual-glass modules, N-type bifacial dual-glass modules, and modules featuring various encapsulation structures.
Based on cell technology, bifacial dual-glass solar panels are primarily classified as either P-type or N-type. P-type bifacial dual-glass modules typically utilize P-type monocrystalline silicon cells, achieving bifacial power generation through optimized cell structures; characterized by mature manufacturing processes and lower production costs, they were widely used in the early bifacial PV market. In contrast, N-type bifacial dual-glass modules employ N-type silicon cell technologies-such as TOPCon and HJT-offering higher conversion efficiency, lower power degradation, and superior performance in low-light conditions, making them a key focus of current development in the photovoltaic industry.
Based on cell structure, bifacial dual-glass solar panels can also be categorized into types such as full-cell modules, half-cut cell modules, and multi-busbar (MBB) modules. Half-cut cell modules-created by cutting a full cell into two halves and reconnecting them-reduce internal current losses and increase module output power, while also improving performance in shaded conditions. Multi-busbar designs increase the number of conductive lines on the cell, thereby reducing resistive losses and enhancing the cell's current-carrying capacity and reliability.
Depending on the specific application scenario, bifacial dual-glass solar panels can be further classified into standard modules and those designed for specialized environments. For instance, ground-mounted PV power plants typically prioritize power generation gain and long-term reliability, whereas residential and commercial/industrial projects place greater emphasis on module dimensions, ease of installation, and aesthetic compatibility. As photovoltaic technology continues to evolve, bifacial dual-glass solar panels are trending toward higher efficiency, greater reliability, and lower costs, offering increasingly flexible PV solutions for diverse application sectors.
