The Suntech Ultra V Pro STP440S-H48-Nth+ is a 440W N-type TOPCon bifacial dual-glass solar panel designed for residential and commercial rooftop systems. It delivers 22.0% front-side module efficiency in a compact 1762 × 1134 × 30 mm format, with a transparent black glass-glass design and 80 ±5% bifaciality.
Its 1.6 mm + 1.6 mm semi-tempered dual glass, multi-busbar technology and strong low-light performance make it a practical option where durability, rooftop appearance and additional rear-side energy generation are important.

The STP440S-H48-Nth+ combines N-type TOPCon cells with multi-busbar technology to improve current collection and optical utilisation.
This design supports efficient power generation while also helping maintain output under lower-light conditions such as cloudy weather, mornings and evenings.
With dimensions of 1762 × 1134 mm and a weight of 21.5 kg, this module remains relatively compact for a bifacial dual-glass panel.
In practical rooftop installations, it can suit:
Metal roofs with compatible rail mounting
Concrete and terracotta tiled roofs
Residential roofs with limited usable area
Small to medium commercial rooftops
Elevated or open mounting layouts where reflected light can reach the rear glass
Its compact footprint can make system layout easier than larger commercial-format modules.
The transparent dual-glass design allows reflected light reaching the rear surface to contribute additional power generation.
The bifaciality factor is: 80 ±5%.
For the 440W model, reference rear-side gains are:
| Rear-Side Gain | Maximum Power | Effective Module Efficiency |
|---|---|---|
| 5% | 462W | 23.1% |
| 15% | 506W | 25.3% |
| 25% | 550W | 27.5% |
Actual bifacial gain depends on mounting height, surface reflectivity and installation conditions.
The module uses 1.6 mm + 1.6 mm semi-tempered front and rear glass with an anodised aluminium alloy frame.
Maximum static load is: 5400 Pa front / 2400 Pa rear.
The junction box is IP68 rated and incorporates three bypass diodes.

The Suntech Ultra V Pro 440W combines N-type TOPCon technology, bifacial generation and dual-glass durability in a relatively compact residential-format module. It is particularly suitable for rooftops where strong low-light performance, additional rear-side generation and manageable panel dimensions are important.
All our products are covered by the Manufacturer's Warranty, which guarantees that they will be free from defects in materials and workmanship under normal use and service. The specific terms and duration of the warranty may vary depending on the product and the manufacturer. Please refer to the product's documentation or contact our customer support team for detailed warranty information.
Warranty Claim Process
In the unfortunate event that you encounter a faulty product, we want to make the warranty claim process as seamless as possible for you. To initiate a warranty claim, please follow these steps:
If damage is confirmed to be from normal wear-and-tear, drops, unauthorized repairs, or other non-warranty factors, service and shipping fees will apply. In such cases, we will contact the customer for approval before proceeding with paid repairs.
Unfortunately we cannot provide loaner units during the warranty repair process. For mission-critical equipment, we highly recommend purchasing backup units to prevent downtime in case of defects.
You have 30 calendar days to return an item from the date you received it.
To be eligible for a return:
Upon receiving your order, we kindly request that you thoroughly inspect all packages within 7 days of delivery. This inspection period is crucial as it allows you ample time to identify any visible damage caused during transit. Please keep in mind that promptly reporting any freight damage is vital in safeguarding your right to file a claim and ensuring a swift resolution.
Should you identify any freight damage during the inspection, we urge you to notify us immediately. Our customer support team is ready to assist you through the claim filing process and provide the necessary guidance to ensure a smooth and hassle-free experience.
The advertised price for this product includes the applicable STC battery rebate, applied as a pre-discount at the time of purchase.
To be eligible for the battery rebate:
Supply-only purchases are not eligible for the battery rebate.
By proceeding with this purchase, the customer agrees to assign all eligible Small-scale Technology Certificates (STCs) associated with the battery installation to Solar Battery Supermarket (or its nominated agent).
This assignment allows the rebate to be applied as a point-of-sale discount.
If the customer does not agree to assign the STCs, the full non-rebated price of the battery system will apply.
Installation by a licensed and accredited installer is mandatory to qualify for the rebate-adjusted price.
Standard metro installation is available from $500, subject to property assessment.
Additional works (including switchboard upgrades, long cable runs, or non-standard installations) may incur extra charges and will be quoted and approved prior to installation.
To assess eligibility and proceed with installation, the customer may be required to provide:
Failure to provide required information may delay installation or affect rebate eligibility.
