Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (495 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 495 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 495 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.

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. The score uses the highest exact manufacturer bin; no market scope is claimed. Scored model: AIKO-A495-GRH48Dw · checked 2026-08-21. Evidence.

Strong evidence coverage
21 of 21 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 a guarantee that a claim is correct.
How far the evidence reaches
1 of 3 questions with checkable rows has a row beyond the maker's claim.
- Output1 of 6 checkable rows beyond the maker's claimMaker-only: 4 maker's commitments
- Endurance5 checkable rows, none beyond the maker's claim
- SafetyNot scored for panels
- BackingMaker-only: 2 maker's commitments; no checkable rows
- Fit1 checkable row, not beyond the maker's claimMaker-only: 3 design facts
- FootprintNo audit rows recorded for this product
- Third-party source
- Certified or regulator-listed
- Manufacturer claim
- Reviewed absence
Each bar is one question's checkable rows for this product at true share, stronger tiers first; hatching marks a reviewed absence: not published, we looked. Maker-only rows (warranty terms and design facts that rest on the maker's own documents) are counted under each question, never dropped. review.solar has measured none of these rows itself. How the evidence puzzle works
Record revision. Built from AIKO's exact August 2026 V1.1 datasheet. The shared GRH48Dw code is not treated as permission to merge the bifacial and monofacial catalogue entries. First-market overlay review 2026-08-30: AU, US and DE overlays recorded from official regional surfaces; scores and identities unchanged.

DE Warranty scope
- Current text
- Germany; the German V4.1 sheet prints a 15-year product graphic, extendable to 25 years, and a 30-year performance graphic. Distributed Common Modules 1.6.3 names MAH78Dw and MCE54Dw but does not name GRH48Dw, so six-field terms are not transferred from that instrument or from the datasheet graphic. Rechecked 7 October 2026: the five German-language Modulgarantie documents on AIKO's German resource centre (WI-0BQM-M005, M006, M008, M009 and M021, listed 22 November 2025) and the five English warranty documents on the global resource centre (Residential Modules 1.7.2, Full-black Gen 3 Infinite Modules 1.1.1, Distributed Common Modules 1.6.3, Utility-Scale Module Warranty 1.6 and Lightweight Module Warranty 1.5) do not name GRH48Dw. The English product page's Download Warranty button points to Residential Modules 1.7.2, which does not list GRH48Dw and states a 25-year product term in clause 2.1; it is not joined to this model.
