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 JAM54D50-530/GR, 535/GR, 540/GR and 545/GR with approval from 8 July 2026 to 8 July 2029. | 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 2026 global JA Solar warranty names JAM54D50-XXX/GR with a 15-year product term and 30-year power term for modules first sold on or after 16 June 2026. JA Solar's current Australian CEC warranty instrument reviewed does not name D50, and the global instrument routes governing law through the original supply contract. Exact Australian remedy, cost and transfer terms therefore remain held. | 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 | Not published in a current exact-family Australian governing instrument; no credit awarded. | 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 | Not published in a current exact-family Australian governing instrument; no credit awarded. Not published in a current exact-family Australian governing instrument; no credit awarded. | 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 | Not published in a current exact-family Australian governing instrument; no credit awarded. | 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 | Not published in a current exact-family Australian governing instrument; no credit awarded. Not published in a current exact-family Australian governing instrument; no credit awarded. | 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 | JA Solar publishes a current Australian office and service contact, but local contact does not by itself make JA Solar Australia Pty Ltd the warrantor for D50. The exact global D50 warranty and current AU approval support duration and output only; no Australian exact-family governing instrument was recovered. | 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.
