# A.B. Energy vs QSun Solar

Both brands are closely matched on catalog size, efficiency and bifacial share - the choice comes down to local availability, price and specific model features.

## Summary

Q-SUN Solar is a Chinese photovoltaic manufacturer with its international headquarters in Nanjing, Jiangsu, and production sites in Tianchang, Yancheng, and overseas locations in Oman and Bulgaria. Founded in 2014, the company claims annual module shipments of more than 8 GW across more than 50 countries, based on its own corporate materials; independent BloombergNEF Tier 1 bankability confirmation for Q-SUN specifically was not surfaced by available sources, though the brand is listed across established industry directories such as ENF Solar and Photonik. A.B. Energy is a much smaller Italian concern, registered as A.B. Energy SRLS, whose core activity centers on energy efficiency distribution and consultancy; available sources do not confirm it operates as a panel manufacturer with meaningful production capacity, proprietary technology, or bankability rating, placing it squarely in the niche regional distributor category rather than alongside volume module producers.

On the product side, Q-SUN offers at least three identifiable module families that are confirmed by third-party datasheets: the Mercury Series based on N-type TOPCon cells, targeting residential and commercial rooftop projects; the Nebula Series using heterojunction technology for efficiency-sensitive applications; and the Onyx Series, a full-black residential line. A.B. Energy's solar offering, to the extent it exists as a distinct product line, appears to consist of resold or distributed panels rather than proprietary manufactured modules, and no independent datasheet or cell technology specification was confirmed through available sources.

For a buyer evaluating these two brands in 2025, Q-SUN Solar is the substantially better-documented option - it has a traceable manufacturing footprint, confirmed cell technology families, and international distribution reach. A.B. Energy does not appear to be a comparable panel manufacturer based on available evidence, and any specific product claims from that brand would warrant direct verification before a procurement decision is made.
