The Trina Solar Panel Vertex S+ TSM-450NEG9R.25 is a 450W N-type i-TOPCon dual-glass designed for residential and C&I rooftop systems. It delivers 22.5% module efficiency in a compact 1762 Γ 1134 mm format, with an all-black front appearance suited to modern Australian homes.
Its lightweight 21.0 kg construction, 30 mm black anodised aluminium frame and compatibility with mainstream inverters, optimisers and mounting systems make it a practical option for rooftop installations where aesthetics, handling and reliability matter.

The TSM-450NEG9R.25 delivers 450W output with 22.5% module efficiency under STC conditions.
Trina Solar combines N-type i-TOPCon cells with high-density interconnect technology to increase power output while maintaining a relatively compact module size. The datasheet also highlights improved warm-weather performance through a low temperature coefficient and lower operating temperature.
With dimensions of 1762 Γ 1134 mm and a weight of 21.0 kg, this panel is relatively compact and easy to handle compared with larger commercial-format modules.
In practical installations, it can be suitable for:
Colorbond and other metal roofs with compatible rail mounting
Concrete and terracotta tiled roofs with appropriate mounting hardware
Residential roofs with multiple roof sections where a shorter module can provide more layout flexibility
Homes where a full-black panel appearance is preferred
Small to medium C&I rooftops using mainstream mounting systems
These roof-type examples are practical inferences based on the module size, weight and stated mounting compatibility; the datasheet itself does not specify individual roofing materials.
The module uses:
Front glass: 1.6 mm high-transmission AR-coated heat-strengthened glass
Back glass: 1.6 mm heat-strengthened glass
The dual-glass construction is designed for improved durability and resistance to harsh environmental conditions, while the black frame and full-black front appearance provide a cleaner look for visible residential rooftops.
The Pmax temperature coefficient is: -0.29%/Β°C.
This helps reduce output losses as module temperature rises, making the panel relevant for hot Australian rooftop conditions.
The operating temperature range is: -40Β°C to +85Β°C.

The uploaded datasheet lists IEC 61215, but it does not explicitly state the βIEC 61215:2021β edition. I would therefore avoid adding βIEC 61215-2021β to the Shopify description unless that edition has been separately confirmed for this exact product.
The TSM-450NEG9R.25 is a strong option for Australian residential rooftops where a compact module size, all-black appearance and reliable dual-glass construction are important. Its 450W output, 22.5% efficiency and mainstream mounting compatibility make it particularly practical for homes with segmented roof layouts or limited usable roof area.
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.
