## Summary

JA Solar, founded in 2005 and headquartered in China, is one of the world's largest solar module manufacturers, with a declared production capacity exceeding 100 GW and a workforce of over 37,000 employees. Listed on the Shenzhen Stock Exchange (SZSE) and holding Tier 1 bankable status, the company serves residential, commercial, and utility-scale markets globally through a portfolio of 524 panel models, reaching a peak output of 740 Wp and a maximum efficiency of 24.4%. Meyer Burger, by contrast, is a Swiss precision engineering company founded in 1953 and listed on the SIX Swiss Exchange, which pivoted from supplying solar production equipment to manufacturing premium panels itself. Its portfolio is narrow - just 24 models with a peak power of 560 Wp and maximum efficiency of 21.8% - but it is built entirely around heterojunction (HJT) cell technology, widely regarded as a step above conventional PERC. Both companies hold Tier 1 bankable status, yet they differ fundamentally in scale, pricing strategy, and - critically at the time of this comparison - operational continuity.

JA Solar's lineup is anchored by PERC technology (52.1% of the portfolio), with TOPCon increasingly represented in newer high-output series. An average panel output of approximately 441 Wp, a temperature coefficient of -0.323%/°C, and 44.3% bifacial penetration make JA Solar modules a versatile fit for rooftop residential installs, commercial C&I projects, and large utility-scale ground-mount arrays alike. Meyer Burger's entire range uses HJT cells, delivering a notably better temperature coefficient of -0.259%/°C - a meaningful real-world advantage in warm climates or poorly ventilated roof installations where power loss on hot days is a key concern. With 58.3% of its portfolio being bifacial and an average output of approximately 419 Wp, Meyer Burger panels were particularly well suited to space-constrained commercial and industrial rooftops where per-square-meter energy yield matters most.

For most buyers weighing performance against cost and supply-chain reliability, JA Solar is the clear practical choice - its global manufacturing scale, broad distribution network, and competitive pricing make it easy to specify across virtually any project type or budget. Meyer Burger's HJT technology genuinely outperforms PERC on thermal behaviour and real-world yield, and the premium was justifiable in stable conditions. However, in May-June 2025 Meyer Burger's German manufacturing subsidiaries - including the solar cell plant in Thalheim and the R&D unit in Hohenstein-Ernstthal - filed for insolvency, and its US factory in Arizona was simultaneously closed. Only a small Swiss entity of roughly 60 employees in Thun remains operational. This effectively leaves Meyer Burger without meaningful manufacturing capacity, posing serious questions about long-term warranty backing and product availability that buyers must carefully weigh before specifying the brand in new projects.
