SMA Solar vs A.B. Energy - solar panel manufacturer comparison
Both brands are closely matched on catalog size, efficiency and bifacial share - the choice comes down to local availability, price and specific model features.
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

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.
What each of them builds
Written summary
SMA Solar Technology AG is a German company founded in 1981 and headquartered in Niestetal, Hesse, Germany, originally spun out of research at the University of Kassel. It is not a solar panel manufacturer in the conventional sense but rather the largest Europe-based solar technology company by revenue, specializing in inverters, battery storage integration, and energy management systems for PV installations of all scales. With worldwide sales exceeding EUR 1.9 billion and roughly 4,400 employees across offices in 20 countries as of 2023, SMA has a decades-long track record and has been listed on the Frankfurt Stock Exchange since 2008. A bankability report published in 2025 placed the company at a B rating - down from AAA in the 2021-2023 period - following two years of falling inverter prices and reported net losses exceeding US$75 million in 2025. The company expects a return to positive operating earnings by 2026.
AB Energy (Gruppo AB), also founded in 1981 and headquartered in Orzinuovi, Brescia, Italy, occupies an entirely different segment of the clean-energy market. The company designs, manufactures, and services cogeneration and biogas-to-biomethane systems under its ECOMAX brand rather than producing photovoltaic panels or inverters. Over 1,250 cogeneration plants have been installed globally, representing more than 1,600 MW of nominal electrical capacity, and the group operates across 22 countries with more than 1,400 employees. Its renewable-energy credentials rest on bioenergy and gas-engine efficiency rather than solar photovoltaics.
A direct comparison as solar-panel manufacturers is not possible here because the two companies do not compete in the same product category. SMA Solar is the relevant name for a buyer or project developer seeking proven European inverter technology, while AB Energy is the appropriate reference for cogeneration, biogas upgrading, or biomethane infrastructure. If the procurement decision genuinely involves PV system components, SMA Solar is the clear default choice of the two, though buyers should weigh its current financial pressures against the stronger balance sheets of competing inverter brands before committing to long-term service contracts.
