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 list includes SRP-440-BTE-BG through SRP-455-BTE-BG as bifacial modules, certificate Z2 098455 0003 Rev. 05, with approval through 27 August 2027. | 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 | The governing 2025 dual-glass warranty expressly includes SRP-XXX-BTE-BG. It provides a 15-year product warranty and a 30-year TOPCon performance warranty ending at 87.4%. Authorised documented shipping may be reimbursed, but installation, removal, reinstallation, customs and transit insurance are excluded. | 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 | Repair, replacement or another remedy under the governing terms. | 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 | Installation, removal and reinstallation are excluded. Installation, removal and reinstallation are excluded. | 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 | Reasonable documented shipping is reimbursable only with Seraphim customer-service authorisation; customs and transit insurance are excluded. | 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 | Transfer is conditional on the modules remaining at their original registered location; moving them from the original continent of destination voids the warranty. No separate product-registration condition was located in the governing exact-family warranty. | 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 technical datasheet also publishes 435 W and 460 W variants. They are excluded because only the exact 440-455 W BTE-BG codes were current Australian approved-module entries at review. | 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.
