marks the better value on rows where a higher number is better. Temperature coefficient counts as higher when it is closer to zero. Size measures such as rated power carry no marker, because a larger product is a different choice rather than a better one.

| Certifications | The current Australian approved-module export lists TWMNH-48HD440 through TWMNH-48HD465 to IEC 61215:2021, including the scored 465 W model. The 465 W approval expires on 26 June 2028. | Astronergy Australia's download centre identifies the exact ASTRO N7s CHSM48RN(DG)/F-BH series as CEC approved; its datasheet publishes IEC 61215 and IEC 61730. |
| Warranty scope | Australia only. The current Tongwei limited warranty for Australia (cover dated 30 April 2026; catalogue label AU-A4+Appendix_A5-260827) lists the TWMNH-48HDxxx family with a 25-year product term (clause 3.1.3) and a 30-year power term on front-side output, with 1% first-year degradation, 0.4% annual degradation thereafter and 87.4% at year 30 (clauses 3.2 and 3.2.2). The earlier Australian instrument dated 30 May 2025 lists the same family at 15 years. Which instrument applies to a given purchase is not publicly established. The current instrument starts the term at the earlier of delivery to the direct purchaser or six months after factory-out; the earlier one starts it at the earlier of installation or the 90th day after delivery. | Astronergy's current Australian warranty is published alongside the exact CHSM48RN(DG)/F-BH family. It provides repair, replacement or compensation remedies, conditional freight reimbursement and whole-warranty assignment after prior written notice while the modules remain at the original site. Removal and reinstallation are customer costs. |
| Warranty remedy | At Tongwei's sole choice: repair, replacement or additional modules, power compensation, financial compensation, or refund and return. After repair, replacement or compensation the original remaining warranty term continues and is not renewed. If Tongwei opts for remedies such as replacement or power compensation and the claimed module products are no longer manufactured, unavailable for supply or withdrawn from the market, Tongwei may provide new-technology products to replace them, with total power not less than the total reasonable claimed power of the original products. A refund and return ends the warranty. | At Astronergy's sole discretion: repair, replacement, or fair-market-value compensation for the warranted wattage at the time of claim. A performance claim may instead receive replacement modules. |
| Labour and reinstallation | Direct repair work selected by Tongwei is covered; independent site labour is not separately promised. Costs of dismantling, repacking, installation or re-installation of the modules during power compensation, and other related expenses, are borne by the buyer. | No separate labour reimbursement is stated. The customer bears the costs of dis-installation, repacking, replacement installation and reinstallation. The customer bears the costs of dis-installation and repacking of the defective module, installation of replacement modules and reinstallation of repaired modules. |
| Freight | For repair, replacement or power compensation, Tongwei bears the freight for shipping additional products to the buyer, excluding insurance, air freight, customs clearance, tariffs and other additional costs not caused by Tongwei, such as demurrage or warehousing caused by the buyer's or end-user's negligence. | A return requires Astronergy's RMA. The customer pays return transport first; after an accepted claim, Astronergy reimburses invoiced reasonable return transport up to a written pre-agreed amount and bears reasonable delivery transport for the repaired or replacement product. Taxes, duties, insurance and excess or delay-related costs are excluded. |
| Transfer and registration | Transfers to a lawful successor or assignee while the modules remain intact at the original installation site, with no arrears, assignment of all rights and obligations, and acceptance of the complete warranty. Tongwei may require evidence of succession within 15 working days of its notice. No pre-registration requirement is stated. A claim needs written notice to Tongwei or its authorised distributor with the claimant, a detailed description of the situation, supporting photos or data, module serial numbers and models, purchase vouchers, the module location and any other supporting material Tongwei requests, and must be raised within 30 natural days of finding the breach. Tongwei may issue a return authorisation, and the claimant must cooperate with the return. Tongwei may reject a claim that misses these requirements. | The complete warranty may be assigned to a title holder after reasonable prior written notice. The modules must remain at the original site, Astronergy must have received full payment, and the new owner must accept the warranty if asked. No product-registration condition is stated. A claim must include model and serial details, installation information, proof of purchase and supporting evidence, and must be raised within 30 calendar days of discovery. |

| Review note | The scored TWMNH-48HD465 is current in the Australian approved-module export of 24 September 2026, with approval expiring on 26 June 2028. Tongwei's Australian download page lists the exact 440 to 465 W datasheet (AUS-Ver.20260501) and the current limited warranty. The warranty's importer appendix lists TWMNH-48HD440~480 for Tongwei Solar (Australia) Pty Ltd and TWMNH-48HD440~465 for Blue Sun Group Pty Ltd and One Stop Warehouse Pty Ltd; the Krannich entries cover 440 and 445 W only. The warranty sets remedy, freight, claim and transfer terms and states that Australian Consumer Law guarantees are not excluded. Stock levels are not published in these documents. | The exact 455-475 W family is published by Astronergy Australia. |

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.
Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.
Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.
Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.
Match the exact module model number, power class and label to the final design. Then check the proposed array size, roof layout, inverter limit and any export control as one system.
Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
A score lead is only meaningful inside this shared class or tier. Weigh it against the specification and evidence rows above before deciding.
