Advancing TOPCon PV Technology: The innovation behind ASTRO N7 and N7s modules

About this event

The PV industry is currently embracing a new wafer type, the rectangular wafer, with a focus on two main formats: 210mm*182mm and 191mm*182mm. The primary reason for adopting this new wafer shape is to optimise shipping container space and reduce shipment and balance-of-system costs.

Astronergy has introduced its latest module product series, ASTRO N7 and ASTRO N7s, both of which utilise rectangular wafers. ASTRO N7, based on the 210mm*182mm wafer, is specifically tailored for utility-scale systems. It features dimensions of 2382mm*1134mm and a 66-cell layout design that effectively lowers Voc and increases string size. This design feature significantly reduces tracker and cable costs, leading to a reduction in LCOE by 0.44% to 4.37% compared to 182mm-wafer TOPCon modules. Furthermore, ASTRO N7 incorporates advanced cell and module technologies such as laser-induced firing, super multi-busbar, light-redirecting film, and double-layer coating glass to enhance module power output and reliability.

On the other hand, ASTRO N7s utilizes the 191mm*182mm wafer, along with a zero busbar and tiling film design. This innovative approach maximises power output within a module area of less than 2m², making it ideal for easy rooftop installations.
