Eco-Friendly 660W Lightweight Topcon Half-Cell Solar Panel for Green Energy Solutions

Adopts TOPCon N-type high-efficiency cell technology, achieving module efficiency up to 21.9% and max power output up to 680W.

Advanced half-cell design cuts internal current in half, effectively reducing resistive losses and hotspot risk for higher real-world energy yield.

Outstanding low temperature coefficient, minimizing power loss in high temperature environments for superior output in hot climates.

Ultra-low degradation guarantee: first-year degradation <=2%, annual degradation 2-30years<=0.55% ,retaining >=84% output power at year 30.

Positive power tolerance (0 to +5W or +3%) ensures delivered power never falls below rated, safeguarding customers energy yield and return on investment.

IP68-rated junction box with 3 built-in bypass diodes provides rapid protection during partial shading, effectively minimizing energy loss.

Standard MC4-compatible connectors enable plug-and-play compatibility with mainstream inverters, ensuring quick on-site installation and wide versatility.

Anodized aluminum frame + 3.2mm high-transmission tempered glass, withstanding 5400Pa front / 2400Pa back static load and passing Dia.25mm@23m/s hail impact test.

Max system voltage of 1500Vdc (IEC/UL) reduces string count and BOS costs (cables, inverters), ideal for commercial & industrial and utility-scale plants.

Full international certifications: IEC 61215/61730 performance & safety, plus ISO 9001/14001 and OHSAS 18001 factory system certifications for seamless global market access.
