## Summary

Solitek is a Lithuanian solar panel manufacturer headquartered in Vilnius, founded in 2009 and operating its own production facility since 2013. It is widely cited as the largest solar panel manufacturer in Northern Europe, with an annual module production capacity of approximately 250 MW. The company does not appear on the BloombergNEF Tier 1 list, which is reserved for high-volume producers operating at multi-GW scale, but it holds the Microgeneration Certification Scheme (MCS) certificate for the UK market and has a Cradle to Cradle gold certification - a distinction no other panel maker has claimed. A.B. Energy srls is an Italian firm based in Orzinuovi in the province of Brescia, with roots in the electrical and electronic equipment sector spanning roughly three decades. Independent industry sources are sparse on A.B. Energy specifically as a solar panel manufacturer; the company appears primarily oriented toward cogeneration and broader energy efficiency solutions, with solar modules treated as part of a wider portfolio rather than a core product. On institutional footprint, Solitek has the clearer identity as a dedicated module maker.

Solitek's product line is aimed at the premium European residential and light commercial segment. The company confirmed a shift toward TOPCon cell technology in 2024, unveiling 435 W in-roof modules under its Solid Solrif series with cell efficiency reaching 22.04%, while continuing to offer PERC-based products for cost-sensitive projects. All panels are manufactured using 100% renewable energy, carry a 30-year product warranty and a claimed 50-year operational lifespan, and are described as 98% recyclable. Roughly 80% of Solitek output is exported to markets including Germany, Italy, Austria, the Netherlands, Switzerland, and the United States. For A.B. Energy, no independently verified panel datasheet, cell technology specification, or warranty term could be confirmed through available sources, so any product-level comparison would risk misrepresentation.

For a typical buyer in 2025 seeking verified European-made modules with transparent sustainability credentials and confirmed technical specifications, Solitek is the better-documented and more purpose-built choice of the two. A.B. Energy may serve specific regional project needs in Italy, but the absence of publicly accessible product data makes it difficult to recommend on equal footing without direct engagement with the company.
