TCL Solar: 620W G12R N-Type TOPCon Bifacial – VOC: 48.94V / ISC: 16.05A (HSM-ND66-GR620)

TOPCon (Tunnel Oxide Passivated Contact) technology is one of the most advanced solar cell technologies available today, designed to deliver high efficiency, reliability, and long-term performance. Building on traditional PERC technology, TOPCon introduces an ultra-thin tunnel oxide layer and a passivated contact structure that significantly reduce the electron recombination losses. This means more of the sunlight hitting the panel is converted into clean, usable energy. With its blend of high efficiency, low degradation, and excellent performance in both harsh conditions and low-light environments, TOPCon has rapidly become the preferred choice for residential rooftops, commercial buildings, and utility-scale solar farms aiming to maximize energy production from every square meter.​

TCL Solar TOPCon panels deliver significant benefits over PERC technology, producing more energy through higher efficiency, lower annual power degradation, better performance in high temperatures and low light conditions. They also offer enhanced reliability, and more efficient bifacial production, leading to more power generation per square meter, better value over the long term, and excellent reliability for installations in harsh environments. With superior performance in all operating conditions, TCL Solar TOPCon sets a new benchmark for high-efficiency, future-proof solar technology.
