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 CER export lists REC450AA, REC455AA, REC460AA, REC465AA, REC470AA and REC475AA Pure-RX through 9 July 2029. Older 440 W and 445 W approvals are outside the current exact datasheet range. | The current CER export lists AIKO-A475-MCE54Mw, AIKO-A480-MCE54Mw, AIKO-A485-MCE54Mw, AIKO-A490-MCE54Mw, AIKO-A495-MCE54Mw and AIKO-A500-MCE54Mw through 4 June 2028. |
| Warranty scope | Australia; REC Alpha warranty Rev 8 explicitly names Alpha Pure-RX and REC Solar Pte. Ltd. as warrantor. Standard cover is 20 years product and 25 years performance, with 98% in year one, 0.25% later annual degradation and 92% at year 25. Conditional REC ProTrust can extend product and labour benefits when its installer, registration and system-size conditions are met. | Australia; warranty 1.6.3 explicitly names AIKO-Axxx-MCE54Mw. The public baseline is 15 years product and 30 years performance, with 1% first-year and 0.35% later annual degradation to 88.85% at year 30. Paid 20- or 25-year product extensions require a recorded sales contract and separate paid agreement. |
| Warranty remedy | At REC's choice: repair, equivalent replacement or refund of the current market price; a performance claim may instead receive additional panels. | At AIKO's choice: repair, replacement or additional modules, residual-value refund, or payment for a warranted power shortfall. |
| Labour and reinstallation | The standard warranty excludes on-site labour. Eligible REC ProTrust systems receive a fixed labour payment to an REC Certified Solar Professional, not uncapped labour cover. The standard warranty excludes de-installation, removal and reinstallation costs. | AIKO may perform its chosen repair, but the voluntary warranty does not promise reimbursement of independent site labour. Removal, repacking, installation and reinstallation costs are borne by the customer. |
| Freight | REC covers non-air transport to a REC-designated facility. Freight beyond that facility, including delivery to the buyer's site, is discretionary case by case. | AIKO bears inspection freight only when responsible. Remedy freight and related costs otherwise follow the original sales-contract destination and Incoterms. |
| Transfer and registration | Transfers to a subsequent owner of the same unaltered solar facility while the panels remain installed at the original property. Proof of each sale is required with a claim. No pre-registration is required for the standard warranty. ProTrust requires an REC Certified Solar Professional installation and installer registration with REC. | Transfer requires AIKO approval and a tripartite agreement. The modules must remain at the original site, all amounts must be paid and the new owner must accept the complete warranty. No pre-registration is stated for the 15-year baseline. Paid 20- or 25-year extensions must be recorded at sale and supported by a separate paid warranty agreement. |

| Local product pathway | No separate local pathway recorded | No separate local pathway recorded |

| Review note | The warranty routes claims first through the authorised seller or distributor and then REC's regional office. Its Australian annex names current Pure-RX distributors, but the warrantor remains REC Solar Pte. Ltd. in Singapore. No separate Australian REC entity is inferred as warranty obligor. | AIKO publishes the exact family and an Australian sales path. AIKO Energy Australia Pty. Ltd is an active Australian entity, but the governing warranty names Zhejiang Aiko Solar Technology Co., Ltd. and affiliated companies under common control. The ABR record is local-presence evidence, not proof that the Australian entity is the warranty obligor. |

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.
