| Certifications | CS6.2-48TD-470 is in the current Australian approved-module export through 14 February 2028. Higher generic suffixes do not prove the all-black construction. | 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 and New Zealand; TopHiKu warranty V2.0 explicitly includes CS6.2-48TD and gives its black and all-black variants a 25-year product term plus 30-year power cover at 87.4%. | 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 | CSI Solar may repair, replace, add modules, or provide the applicable fair-market-value or output-gap refund. | 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 | Reasonable repair material and labour are covered when CSI Solar selects repair. Removal, installation and reinstallation remain with the buyer. Removal, installation and reinstallation remain with the buyer unless CSI Solar agrees otherwise in signed writing. | 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 | After authorization, CSI Solar covers reasonable transport to its nominated point and return transport for the selected remedy. Taxes, duties, insurance and buyer-cooperation costs remain 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 | The warranty transfers to a later legal title holder while the modules remain at the original installation location. No product registration condition is stated. No product registration condition is stated. Claims require prompt written notice, serial numbers and purchase evidence. | 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. |

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.
Both products are scored in the Global Tier-1 class, on the same rubric weighting. Scores are not comparable across classes or tiers. Full methodology.
