## Summary

AE Solar was founded in 2003 by Alexander Maier and his brothers in Königsbrunn, Bavaria, Germany, where the company is still headquartered. It operates manufacturing facilities in China (since 2009), Georgia (since 2019), and Kayseri, Turkey (since 2021, with capacity exceeding 1 GW at that site alone), giving the group a combined annual production capacity of 2.5 GW. AE Solar appeared on the BloombergNEF Tier 1 PV Module Manufacturer List for the 16th time in Q1 2025 and holds the distinction of being the first DIBt-certified Tier 1 module maker in the industry - a meaningful credential for project finance in European markets. The company also received the Kiwa PVEL Top Performer Award in 2025 and is present in more than 95 countries. Resun Solar, headquartered in Changzhou, Jiangsu, China, has been operating since approximately 2005 and manufactures mono- and polycrystalline modules across a wide wattage range. It holds standard industry certifications including TUV, IEC61215, IEC61730, and CE, and its panels have been declared PID-free by PI-Berlin. Resun does not appear on published BloombergNEF Tier 1 lists, and production capacity figures vary considerably across sources, making direct comparison difficult. On institutional footprint, AE Solar holds a clear advantage.

For residential and commercial buyers, AE Solar targets a broad spectrum of applications - from residential rooftop installs to commercial C&I projects and utility-scale ground-mount - and markets itself on innovation credentials such as NFC-chip anti-counterfeiting and shade-resistant module design. Its 30-year product warranty exceeds the typical industry standard of 10 years. Resun Solar addresses residential rooftop and smaller ground-mount segments with a cost-competitive positioning, offering modules including monofacial, double-glass, and BC-family variants across a power range from 5 W to 720 W. The company cites over 15 years of experience supplying solar home systems for World Bank projects across multiple continents as evidence of its reliability track record.

For international buyers choosing between the two, AE Solar offers a stronger bankability profile - confirmed Tier 1 status, European manufacturing presence, and independently validated performance awards - making it the more straightforward choice for projects requiring project finance or long-term institutional backing. Resun Solar may appeal to price-sensitive buyers or markets where BloombergNEF Tier 1 status is not a procurement requirement, though the lack of independently confirmed capacity figures and Tier 1 recognition are factors worth weighing before committing to large volumes.
