## Summary

Boviet Solar was founded in 2013 in Vietnam and has grown to a production capacity of 3 GW with a workforce of over 1,000 employees. Despite being a smaller-scale producer relative to the dominant Chinese manufacturers, Boviet holds Tier 1 bankability status and has earned PVEL Top Performer recognition for multiple consecutive years, demonstrating consistent module quality. Its portfolio of 60 modules is built primarily around PERC-based monocrystalline technology. JA Solar, by contrast, was founded in 2005 in China and is publicly listed on the Shenzhen Stock Exchange. With over 37,000 employees and manufacturing capacity exceeding 100 GW, it consistently ranks among the top global module suppliers by shipment volume - earning a joint top position in Wood Mackenzie's Global Solar Module Manufacturer Ranking for the first half of 2025. JA Solar's portfolio spans 524 module variants, reaches a peak efficiency of 24.4%, and has rapidly shifted output toward N-type TOPCon technology, which accounted for over 95% of shipments in Q1 2025.

Boviet's standout portfolio characteristic is its high share of bifacial modules - 66.7% of its lineup - combined with an average module power of approximately 484 Wp and a maximum efficiency of 22.7%. This makes Boviet well suited for residential rooftop installations and small-to-medium ground-mount projects where bifacial energy gain is a priority. Its average temperature coefficient of -0.336%/°C is in line with standard PERC performance. JA Solar's breadth of offering, with modules reaching 740 Wp, positions it strongly for utility-scale ground-mount and large commercial C&I projects. Its slightly better average temperature coefficient of -0.323%/°C provides a marginal real-world yield advantage in warm climates. The company's global distribution network and extensive track record across European and emerging markets make it a reliable default for large-scale procurement.

For international buyers choosing between the two, JA Solar is the natural fit when maximum panel power, cutting-edge efficiency, and supply chain depth are the primary criteria - particularly for projects above 1 MW or where TOPCon technology is specified. Boviet Solar represents a compelling niche option for buyers seeking a Tier 1-certified, PVEL-validated alternative with a strong bifacial portfolio and Vietnamese manufacturing origin - a factor that may carry weight for procurement teams diversifying away from Chinese-origin modules in response to evolving trade policy in the US and EU markets.
