Description Suntech STP575S-C72/Nsh+

Solar panel Suntech STP575S-C72/Nsh+

On a flat commercial roof with parallel rows of modules, bifacial output stops being a bonus and becomes a design tool. The Suntech STP575S-C72/Nsh+ is a 575 W bifacial module built on the Ultra V Pro N-type platform from 144 half-cells, and it's exactly this kind of site where the technology pays off most: a light-coloured roof membrane or gravel ballast under the array reflects extra light onto the rear side of the cells, lifting real output per square metre of roof without adding roof area.

22.26% efficiency — less roof per kilowatt

The module rates at 22.26% efficiency, a figure that directly sets how much roof area a planned system capacity requires. On commercial sites, where roof area is usually a hard constraint rather than a preference, every efficiency point converts into either extra modules that fit or fewer mounting rows for the same kilowatt-peak.

N-type TOPCon in a half-cut layout

144 half-cut N-type TOPCon cells are now the industry's mainstream replacement for P-type PERC. Half-cutting lowers current loading per cell and, with it, internal resistive losses, while N-type silicon skips the light-induced degradation that used to shave output off the previous generation in its first weeks. For a commercial project where the station has to reach its projected payback without surprises, that's predictability built into the hardware.

Glass-on-glass, IP68 and low-touch operation

The glass-on-glass build rated IP68, operating from -40°C to +85°C, is built for years of service without constant hands-on attention — the typical rhythm for commercial installations serviced on a schedule rather than weekly. A glass rear sheet resists moisture ingress and potential-induced degradation (PID) better than a backsheet panel, which matters under a damp climate.

1500 V and project-level economics

A 1500 V maximum system voltage lets a design engineer build longer strings, cutting the number of parallel groups, connectors and, in turn, spend on cabling and MPPT channels on the inverter. On industrial-scale sites that saving shows up already at the costing stage.

A note from project designers

Experience from completed commercial projects shows the real generation gap between a standard and a bifacial module on the same roof area is most visible where the surface is light or reflective — PVC membrane, light gravel, galvanised roofing. Where the base is dark and absorbs rather than reflects, the gain is more modest, so it's worth assessing the roofing surface as part of the sizing exercise before committing to a design.

Who it suits

Suntech STP575S-C72/Nsh+ fits mid-to-large commercial roofs, warehouse complexes and industrial sites where high efficiency per square metre, bifacial gain and a durable glass build for long, low-maintenance service all matter.
