Product Description

PERC (Passivated Emitter and Rear Contact) solar photovoltaic panels are built on conventional monocrystalline silicon cells with an added passivation dielectric layer on the rear side, forming a locally opened rear contact structure that effectively reduces rear-side carrier recombination and improves photoelectric conversion efficiency. PERC technology is the mature mainstream solution for P-type silicon cells, achieving mass production cell efficiencies of 22%~24% and module efficiencies of 19.9%~21.57%.

PERC modules adopt Multi-Busbar (MBB) and half-cut cell technology, effectively reducing resistive losses and improving micro-crack resistance. The cells use gallium-doped wafers, significantly reducing Light-Induced Degradation (LID), with first-year degradation controlled within 2% and subsequent annual linear degradation of approximately 0.45%. Bifacial dual-glass PERC modules achieve bifaciality of 75%~80%, enabling an additional 10%~20% rear-side power gain on high-albedo surfaces.

The front side uses 3.2mm ultra-white anti-reflective coated tempered glass, with an anodized aluminum alloy frame and IP68-rated junction box. The modules withstand 5,400Pa snow load and 2,400Pa wind load, operating within -40℃ to 85℃, with resistance to salt mist, ammonia corrosion, PID, and sand/dust. PERC technology offers mature supply chains, low manufacturing costs, and high cost-performance, making it a reliable choice for distributed PV and large-scale ground-mounted plants.

System Components

PERC PV modules consist of P-type monocrystalline PERC cells, 3.2mm ultra-white anti-reflective coated tempered glass, EVA/POE film, TPT backsheet or rear glass, anodized aluminum alloy frame, IP68 junction box, and MC4-compatible connectors. Cells are soldered in series/parallel using Multi-Busbar (MBB) and half-cut technology, laminated and encapsulated, then assembled with the frame. Bypass diodes are built into the junction box to prevent hot-spot effects. The module outputs DC power through MC4 connectors, directly connectable to PV inverters or combiner boxes, suitable for grid-connected, off-grid, and hybrid power generation systems.
