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 (1000W/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. The score uses the highest exact manufacturer bin; no market scope is claimed. Scored model: AIKO-A495-GRH48Dw · checked 2026-08-21. Evidence.
Sources & references · checked 2026-08-30
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 an independent guarantee that a claim is correct.
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 Certifications
- Before
- Not previously recorded
- After
- The August 2026 German datasheet V4.1 for Neostar 2P+48 names AIKO-A465-GRH48Dw through AIKO-A495-GRH48Dw and prints IEC61215/IEC61730.

AU Support Note
- Before
- Not previously recorded
- After
- AIKO's Australian catalogue checked 30 August 2026 does not list NEOSTAR 48 dual glass. The CER approved-module export last modified 20 August 2026 has no GRH48Dw row.

DE Support Note
- Before
- Not previously recorded
- After
- AIKO's German product page and German V4.1 datasheet name AIKO-A-GRH48Dw as bifacial dual glass 465-495 W. The shared GRH48Dw code is not permission to merge this bifacial record with the monofacial 470-500 W sibling. Manufacturer listing is established; distributor inventory is not inferred.

DE Warranty scope
- Before

- 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.
