Epax Solar vs AE Solar - solar panel manufacturer comparison

AE Solar is a German-headquartered photovoltaic manufacturer operating production facilities in China, Georgia, and Turkey, with a combined annual capacity of approximately 2.5 GW. The company achieved its 16th consecutive placement on BloombergNEF's Tier 1 Global PV Module Manufacturer list in Q1 2025 and has been recognized as Europe's sole Tier 1 manufacturer with high bankability for 2024. AE Solar also holds the distinction of being the first DIBt-certified Tier 1 producer and received the Kiwa PVEL Top Performer Award 2025. Wood Mackenzie ranked AE Solar 18th globally among module manufacturers in 2025, making it the only German company on that list. Epax Solar GmbH, by contrast, is an owner-managed firm based in Deggendorf, Bavaria, operating primarily as a PV distributor and wholesaler serving installers and system designers across Germany and wider Europe. Epax Solar carries own-brand panel lines but does not appear on the BloombergNEF Tier 1 list and does not have a comparable manufacturing footprint. On institutional credibility, AE Solar holds a clear lead.

AE Solar's product range centers on N-type TOPCon modules under the Meteor series, reaching up to 725 Wp, alongside hybrid back-contact modules rated at up to 24% efficiency and conventional PERC options. The lineup spans residential rooftop installations, commercial and industrial (C&I) projects, and utility-scale ground-mount arrays, all backed by a 30-year product and performance warranty. PV Magazine awarded AE Solar's TOPCon line a five-star rating in performance testing. Epax Solar distributes components from multiple manufacturers and offers own-brand panels in HJT technology at around 375 Wp and approximately 20.4% efficiency, as well as some N-type TOPCon bifacial models. Its value proposition centers on broad stock availability, short lead times, and flexibility for small-to-medium installers operating in the DACH region and Central Europe.

For a typical international buyer - whether procuring modules for a financed rooftop project or a larger C&I tender - AE Solar is the more straightforward recommendation given its bankability status, verified third-party performance data, and long warranty terms. Epax Solar serves a useful role as a flexible distribution partner but is not a like-for-like competitor in terms of manufacturing scale or institutional standing. The two brands occupy different positions in the supply chain rather than being directly interchangeable.
