An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

Checking cache...

Astronergy is a Chinese photovoltaic manufacturer and a subsidiary of the CHINT Group, one of China's largest energy conglomerates. The company has grown into a top-tier global supplier, reporting shipments exceeding 40 GW in 2024 alone and a cumulative worldwide total surpassing 130 GW, placing it consistently among the top six module producers by shipment volume. Astronergy holds BloombergNEF Tier 1 bankability status and operates nine manufacturing facilities across China, with additional international plants in Thailand and Turkey and a new facility under construction in the United States. Horay Solar is a smaller but credible Chinese manufacturer, founded in 2010 and headquartered in Wuxi, Jiangsu Province. The company achieved BloombergNEF Tier 1 status and retained it into Q1 2026, with an annual production capacity of approximately 2.5 GW and manufacturing operations in both China and Malaysia. On the basis of scale, cumulative shipment history, and institutional backing, Astronergy commands a considerably stronger global footprint.

Astronergy's portfolio is anchored in n-type TOPCon technology across all major market segments. Its ASTRO N series - including the ASTRO N7 and N7s lines unveiled at SNEC 2025, which feature a Zero-Busbar TOPCon cell architecture - targets utility-scale ground-mount projects where high power density and low balance-of-system costs are the primary drivers. The company also addresses commercial and industrial rooftop installations and residential systems, with flagship module efficiencies reaching 24.4 to 24.5%. Astronergy panels earned Top Performer recognition from PV Evolution Labs in 2024, ranking highly across six out of seven reliability test categories. Horay Solar similarly centers its current line-up on n-type TOPCon modules, carrying certifications from TÜV, IEC, CE, INMETRO, and CQC, and covering residential, commercial, and utility-scale use cases. Independent reliability benchmarking results are, however, significantly less visible in the public domain for Horay Solar than for Astronergy.

For most international buyers - whether procuring modules for a utility-scale project where bankability is non-negotiable, or specifying panels for a commercial rooftop where long-term yield and warranty backing matter - Astronergy is the more defensible default. Its production scale, independent test results, and deep BNEF Tier 1 track record give project lenders and developers considerably stronger grounds for confidence. Horay Solar is a legitimate Tier 1 alternative, particularly in markets or procurement rounds where Astronergy supply or pricing is less competitive, but its smaller production base and thinner publicly available independent testing record make it a secondary option for risk-averse buyers.
