## Summary

JA Solar and HY Solar represent two very different tiers of the global solar manufacturing landscape. JA Solar was founded in 2005 in China and has grown into one of the world's largest module manufacturers, employing over 37,000 people and operating production capacity exceeding 100 GW annually. It jointly topped Wood Mackenzie's Global Solar Module Manufacturer Ranking for the first half of 2025 alongside Trinasolar, and its Tier 1 bankable status is confirmed by S&P Global Commodity Insights. Its shares are listed on the Shenzhen Stock Exchange. HY Solar, by contrast, is a much smaller and less established manufacturer with no Tier 1 designation, a catalog of only 91 modules, and limited public financial history - though its 2025 earnings forecast of RMB 180-250 million (net attributable profit) signals a profitable, if niche, operation. The efficiency gap at the top end is narrow - JA Solar's best modules reach 24.4% versus HY Solar's 23.8% - but HY Solar's average efficiency across its entire catalog (22.94%) is notably higher than JA Solar's portfolio average (20.87%), reflecting HY Solar's focused, premium-only positioning versus JA Solar's broad multi-segment offering.

Technology-wise, HY Solar has committed entirely to n-type TOPCon cells, with 100% of its portfolio bifacial and averaging 571 Wp per panel - a clear signal that the company targets high-density, high-performance installations. Its average temperature coefficient of -0.29%/°C is better than JA Solar's -0.32%/°C, a meaningful advantage in warm-climate or summer-peak generation scenarios. HY Solar's average product warranty also stands at 30 years versus approximately 27.9 years for JA Solar. JA Solar's portfolio spans PERC (52% of catalog) through to advanced TOPCon and its DeepBlue 5.0 flagship series, giving installers a wide price-to-performance ladder. JA Solar has achieved PVEL Top Performer status for the tenth consecutive time in 2025, and real-world field data consistently shows modules performing at or above nameplate. For residential rooftop installs, commercial C&I projects, and large utility-scale ground-mount farms, JA Solar's combination of scale, bankability, and supply chain resilience makes it a default choice for international developers and financiers.

For international buyers choosing between the two, the decision hinges primarily on project type and financing structure. Where bankability, insurer acceptance, and lender familiarity are non-negotiable - as in utility-scale or project-financed C&I installations - JA Solar is the safer, better-documented choice with a decades-long track record. HY Solar is a compelling option for buyers who prioritize cutting-edge TOPCon efficiency and a fully bifacial portfolio in space-constrained residential or commercial rooftop applications, and who are comfortable accepting the reputational and supply-chain risk that comes with a less globally recognized brand.
