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

AEET Energy Group GmbH is a Germany-based photovoltaic wholesale distributor headquartered in Bad Gandersheim, Lower Saxony. Rather than operating its own large-scale fabrication lines, AEET sources modules from third-party factories and markets them under its own brand, positioning itself primarily as a trading and logistics partner for installers and developers across Europe. The company holds TÜV Rheinland certifications on its modules and offers a 10-year product warranty with a 25-year linear performance guarantee, but it does not appear on the BloombergNEF Tier 1 solar module manufacturer list because that designation tracks actual module producers, not distributors. BYD - Build Your Dreams - is a vertically integrated Chinese conglomerate headquartered in Shenzhen, founded in 1995 and best known globally for lithium-ion batteries and electric vehicles. Its solar division has achieved BloombergNEF Tier 1 bankability status, reflecting financeable track record on independently financed projects above 10 MW. BYD carries a substantially larger institutional footprint.

BYD's current panel portfolio spans residential and utility-scale applications, anchored by the MLK bifacial series running from roughly 395 W to 545 W with module efficiency reaching approximately 21% as confirmed by multiple 2025 review sources. The lineup includes both TOPCon and HJT cell technologies, and the premium AURO N series carries a 30-year linear power warranty with a stated maximum annual degradation of 0.5%. Pricing is generally positioned 10-15% below the most premium tier brands while still competing on efficiency. AEET's modules, being sourced from various upstream manufacturers, cover monocrystalline, polycrystalline, and thin-film form factors, making the brand difficult to characterize around a single dominant cell technology. Their offering suits price-sensitive European commercial and small residential projects where local logistics support matters more than bankability on large financed deals.

For a typical buyer financing a mid-to-large solar project in 2025, BYD is the clearer choice: it offers verified manufacturing provenance, Tier 1 bankability for lender due diligence, and a well-documented modern cell technology stack. AEET may suit smaller integrators who value a European-based wholesale partner and do not need to satisfy institutional bankability requirements.
