What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (545 W) applied to the guaranteed floor; modular/format differences aside, this is the same rated-power spec shown above.
Modelled effective output, year by year
Year 1 to year 25, at 30°C and 1000 W/m². Rated 545 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 545 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000 W/m² against the 1000 W/m² STC reference). This is the dominant real-world effect at low light, whether from cloud, shading or soiling. Output is then further derated for heat, from this panel’s own NOCT (45°C) and temperature coefficient (-0.26%/°C), giving an estimated cell temperature of 61°C at that ambient and irradiance. A datasheet-derived estimate, not a field measurement or a warranty guarantee: it does not account for this panel’s own low-light efficiency response (a separate, less-consistently-published spec), or for wind and system design. See NOCT and temperature coefficient in the glossary.

Market context
Global evidencechange in the site menu
Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. Reconciled 4 October 2026: canonical physical measurements and authored AU listing already use 545 W. Scored metadata now uses the same exact JAM54D50-545/GR anchor; global 525–550 W range remains separate. Existing AU 530–545 W range is retained as its dated approval observation, not a fresh renewal. AU warranty terms do not add global scoring credit. Scored model: JAM54D50-545/GR · checked 2026-10-04.

Strong evidence coverage
16 of 16 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

AU Warranty scope
- Current text
- Australian instrument Q/JASO-QAM-125-Aus A/11-Aus, effective 10 May 2026, expressly includes JAMXXD50-XXX/GR under its model-placeholder convention. The D50/GR row gives 15-year product and 30-year power terms, 1% first-year and 0.35% subsequent annual degradation, with 88.85% at year 30. Applies to modules first sold after the effective date; earlier sales retain their original policy. Warranty starts at delivery or six months after factory dispatch, whichever occurs first. JA Solar Technology Co., Ltd. issues the policy; JA Solar Australia Pty Limited receives local claims without automatic reassignment of warrantor liability.

AU Warranty conditions
- Current text
- labour: Independent onsite labour reimbursement is not promised; removal/reinstallation costs remain the customer's responsibility (page 6).; registration: Written claim notice is required within 14 calendar days of awareness or before expiry, with documentary proof and authorised return procedure. This is a claim condition, not a purchase-registration requirement (page 4).; remedy: At JA Solar's option: repair, replacement, depreciated/current-market refund or agreed compensation; the power remedy may include additional modules. Replacement carries the original remaining term (pages 4–5).; removal reinstallation: Removal/reinstallation and customs costs are allocated to the customer (page 6).; transferability: Assignment requires written notice, retention at the original installation site, no outstanding supply-contract payment and the assignee accepting the terms (page 7).; transport: Verified claims may receive actual supported return/testing transport costs under specified conditions. Destination/shipping costs follow the original supply contract; all freight is not unconditionally covered (pages 4–6).

- Exact maker-hosted D50/GR sheet Global-EN-20260624A and Australian governing warranty A/11-Aus were recovered on 4 October 2026. The Australian policy names the D50/GR family, provides a local claim recipient and preserves Australian Consumer Law rights; governing law and disputes otherwise follow the original supply contract. Conditions, remedies and costs are explained below. Current approval renewal and US/DE availability were not rechecked in this bounded integration.
