Skip to content The NASCCLamp NAS-DG Series is a high-efficiency N-type TOPCon photovoltaic module, available from 575W to 590W. Featuring 0BB (busbar-less) half-cut cell technology, this panel increases energy density and delivers higher power output. The N-type cells are boron-oxide-free, effectively eliminating LID (light-induced degradation) and boosting long-term power generation. With a bifacial factor offering up to 25% extra power from the rear side, this module is ideal for ground-mounted and commercial rooftop systems. Passivated contact cell technology ensures stable performance even under high operating temperatures. Designed for distributors, EPC contractors, and project developers in Southeast Asia, Africa, South America, and the Middle East.
