Performance guarantee: 25-year linear output
Wattage figure based on the sourced rated power (440 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. Rated 440 W at STC.
How this is modelled
Modelled from this panel’s own published first-year (1.5%) and annual (0.33%/yr) degradation figures, compounded against its 440 W rated (STC) output. This is a datasheet-derived estimate, not a field measurement or a warranty guarantee. Actual output also depends on site irradiance, temperature, soiling and system design.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score is anchored to the highest published rating in this exact published US series. Scored model: Q.TRON BLK M-G2+ 440 · checked 2026-08-23. Evidence.

Strong evidence coverage
25 of 25 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.

Record revision. Q.TRON BLK M-G2+ Rev02 April 2026 sheet, June 2026 warranty and Hanwha 2025 financials rechecked 2026-08-23. Exact thermal and LeTID review, 6 October 2026: North American Rev02 April 2026 datasheet pages 1–2 include the unsuffixed 440 W model. The manufacturer’s Anti-LeTID claim receives claim-only credit; no IEC TS 63342 test result is established. Published NMOT 43 ±3°C is not relabelled NOCT. The unchanged 170.7 W/m² descriptive density is 333.3 W minimum NMOT output divided by 1.952748 m². The datasheet’s continuous-duty T98 limit of 70°C differs from the generic website’s 85°C operating limit; 85°C is not treated as a demonstrated continuous-duty rating. Existing warranty, market and verification dates remain unchanged; the whole-product depth review is incomplete.

US Warranty scope
- Current text
- Qcells Rev05, issued 1 June 2026, names Q.TRON BLK M-G2+ sold and installed in the United States, Canada, Mexico, Panama or Costa Rica (section 1.a). It provides 25-year product and performance warranties, with remedies chosen by Qcells. Confirmed-claim transport is covered; dismantling and installation costs are excluded (sections 2, 4.d and 5).
The previous text is not reproduced here: both versions run to a full research paragraph. Both are in the JSON record linked below.
Cell technology tierPrimary datasheet+3 in JSON recordUS Warranty conditions
- Current text
- labour: Rev05 offers repair at Qcells’ discretion but is silent on a separate labour reimbursement entitlement. Section 5.d excludes reimbursement of dismantling and installation costs.; registration: Rev05 is silent on warranty pre-registration. Claims must follow Qcells’ current return-authorisation process and include the original receipt or invoice showing purchase and delivery dates, panel serial numbers and the authorised distributor or seller (sections 4.c-d).; remedy: Qcells chooses repair, replacement or monetary compensation; performance claims may also be settled with additional panels. Product compensation applies 4% annual depreciation to the purchase price; performance compensation applies the depreciated price per watt to the guaranteed-output shortfall (Rev05, sections 5.a-b).; removal reinstallation: Rev05, section 5.d, excludes reimbursement of costs incurred in dismantling or installing the original panels, replacement panels or parts.; transferability: Transfers automatically with title while the complete system remains intact at the original installation site; no transfer registration is required.; transport: The customer pays to send panels to Qcells for evaluation. Under Rev05, section 4.d, Qcells pays the technical inspection and transport costs if the claim is confirmed; otherwise the customer is charged those costs.

AU Support Note
- Current text
- Qcells told its Australian team in February 2024 that its Australian subsidiary would be closed and that winding up operations would take a few months. Qcells told SolarQuotes, as reported by pv magazine on 16 February 2024, that modules and batteries would continue to be covered by its manufacturer warranties and that after-sales support would be provided by Zeco; that statement was not reconfirmed against a current Qcells source. The Australian company ABN was later cancelled on 11 November 2025. This exact product remains a valid global comparison record, while historical Australian warranty support is separate from current new-product availability.
