Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
ET Solar is a Chinese solar panel manufacturer founded in 2005 and headquartered in Nanjing, China. The company operates a vertically integrated supply chain covering ingots, wafers, cells, and modules, and has shipped more than 7.2 GW worldwide since its founding. It holds BloombergNEF Tier 1 status, meaning project finance banks have extended non-recourse debt to projects built with its modules - a key benchmark for institutional buyers. Production capacity is estimated at around 1.7 GW per year, placing it in the mid-tier of Chinese manufacturers by volume. Its US operations filed for Chapter 11 bankruptcy in 2017 under pressure from American trade tariffs, but successfully reorganized and relaunched by 2019; in September 2023, Anhui Gourgen acquired a majority stake. On institutional footprint, ET Solar carries measurably more weight than its counterpart here, given its verified bankability and multi-gigawatt global track record.
A.B. Energy srls is an Italian business based in Catanzaro, southern Italy, with roots in the electric and electronic equipment sector. Critically, available sources list it as a solar distributor and seller rather than a panel manufacturer - it resells modules from brands such as REC Solar, JA Solar, Trina Solar, and LONGi Solar, alongside inverters and storage systems. No independent manufacturing review, BNEF Tier 1 listing, or production capacity data exists for A.B. Energy, which is consistent with its role as a regional reseller serving the Italian domestic market rather than a panel fabricator.
A direct product-to-product comparison is therefore difficult to make fairly. ET Solar is a bankable panel manufacturer with its own cell-to-module production line and a global distribution footprint. A.B. Energy is better understood as a procurement channel that supplies panels made by third-party brands. For a buyer seeking manufacturer-backed warranties, bankability certification, and production-level quality controls, ET Solar is the clearer default. Buyers in Italy already working with A.B. Energy as a local supplier should be aware they are effectively buying whichever brand that distributor sources, not an A.B. Energy-fabricated panel.
