The verdict. In our Specialist & Local class, Meyer Burger Glass leads on performance & degradation. See the financial standing note above. A long warranty is only as good as the business behind it.

Compare this panelAsk Watt →
Legacy record. Meyer Burger manufactured the Glass family at Freiberg, where module production closed in the first quarter of 2024. Its later US module operation also shut, German production companies entered insolvency proceedings, and US module-production equipment was sold. The record remains available for installed-product and warranty-history research. Source. Scored 70 under panel v2.10.0 and frozen as of 2026-08-06: this product is no longer in active assessment or live comparison, and its score is not maintained against the current rubric.
Worth knowing. Meyer Burger's German operations entered insolvency in 2025 and its US manufacturing assets were sold. Bankruptcy was opened over Meyer Burger (Switzerland) AG on 23 June 2026 and the entity is now in liquidation. No public warranty-servicing arrangement was located in this review. Treat ongoing warranty support as at serious risk. Source. A warranty is only as valuable as the entity standing behind it. Ask your retailer who services this warranty now.

How this is modelled

Compounds this panel’s own published first-year (1%) and annual (0.2%/yr) degradation figures against its 390 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 (43°C) and temperature coefficient (-0.259%/°C), giving an estimated cell temperature of 59°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.

    Current text
    Meyer Burger manufactured the Glass family at Freiberg, where module production closed in the first quarter of 2024. Its later US module operation also shut and production equipment was sold during insolvency proceedings. On 12 March 2026 Swift Solar acquired Meyer Burger's heterojunction (HJT) patent portfolio, manufacturing assets and personnel. The reviewed sources describe an asset and intellectual-property purchase and do not state that any warranty obligation to existing module owners transferred; readers encountering that acquisition headline should not read it as a restoration of warranty backing. No current Australian channel or applicable Australian warranty was established; retain this as an installed-product legacy record.
