Solitek vs AEET - solar panel manufacturer comparison

Solitek is a Lithuanian solar manufacturer headquartered in Vilnius, founded in 2009 as part of the BOD Group. The company has built an annual module production capacity of around 250 MW, positioning itself as the largest solar panel manufacturer in Northern Europe. Its panels are produced entirely within the European Union using renewable energy, a distinction that carries weight for buyers in markets where carbon footprint and supply-chain provenance matter. Solitek holds Cradle to Cradle GOLD certification - the only solar manufacturer to do so according to the company - though it does not appear on BloombergNEF Tier 1 lists, which typically favor multi-GW-scale players. AEET Energy Group GmbH is a German company based in Bad Gandersheim, active in photovoltaics since around 2004. AEET operates primarily as a full-service photovoltaic wholesale distributor, partnering with leading global module manufacturers, but also markets panels under its own brand. No verified Tier 1 or BloombergNEF bankability designation was found for AEET. In terms of institutional footprint, Solitek's in-house manufacturing at scale gives it the stronger standing as a named panel brand.

Solitek's product range is centered on premium glass-glass modules, including bifacial designs such as the Blackstar series, and building-integrated solutions like the Solid Solrif roof system. Efficiency on recent lines reaches up to 22.93%, confirmed by PV Europe coverage. The 30-year product and performance warranty, with a stated 50-year panel lifespan, targets quality-conscious residential and commercial rooftop buyers across Europe. AEET's own-branded modules are TUV-tested and carry IEC 61215 and IEC 61730 certifications, signaling basic market conformity. Because AEET sources production externally, the underlying cell technology - whether PERC, TOPCon, or HJT - depends on its supply agreements at any given time and could not be confirmed via independent sources.

For a buyer in 2025 who wants a traceable European-made panel with clear sustainability credentials, Solitek is the more transparent choice. AEET's value lies primarily as a distributor that bundles panels with broader PV procurement services, rather than as a standalone brand to specify by name.
