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

G-STAR (trading as Gstar Solar) is a solar module manufacturer headquartered in Singapore and incorporated in 2019 under the Standard Energy Group, a vertically integrated supply chain that includes wafer production in Indonesia and frame manufacturing in Laos. Its most significant recent development is the launch of a dedicated cell and module factory in Subic Bay, Philippines, with a first-phase nameplate of 1.5 GW of cells and 1 GW of modules, with a second phase intended to bring module capacity to 2 GW. G-STAR holds certifications from ETL, TUV, and the California CEC, though its presence on the BloombergNEF Tier 1 bankability list has not been confirmed by available sources. A.B. Energy SRLS, by contrast, is an Italian company rooted in three decades of electrical and electronic equipment trade that operates today as a solar products distributor rather than a panel manufacturer - sourcing modules from established brands such as LONGi, Trina Solar, JA Solar, and REC for resale across the European market. In terms of institutional scale and vertical manufacturing footprint, G-STAR is the larger and more production-oriented entity.

G-STAR's catalog spans residential, commercial, and utility-scale applications, covering P-type, N-type, HJT, and Back Contact cell technologies with outputs from around 100 W to over 700 W. Its May 2025 Philippines launch centered on an N-type bifacial dual-glass module reaching a reported conversion efficiency of 23.03% and a peak output of 595 W. A.B. Energy does not produce panels of its own; its value proposition lies in aggregating proven third-party brands - primarily N-type TOPCon and Back Contact products from top-tier Chinese and European makers - for Italian and European buyers who want local-language support and simplified procurement.

For a buyer seeking a direct relationship with a panel manufacturer, G-STAR is the relevant choice, particularly for projects in markets such as the United States, Europe, or India where its Southeast Asian factories are building trade-compliant supply chains. A.B. Energy fills a different role entirely - it is a regional distributor and is not interchangeable with a manufacturer like G-STAR.
