## Summary

Sunlike Solar is a Chinese manufacturer founded in 2010 and headquartered in China, operating as a mid-scale private enterprise with an annual production capacity of approximately 2 GW across solar cells and modules. The company holds ISO 9001, ISO 14001, and OHSAS 18001 certifications and supplies products calibrated against Fraunhofer ISE standards, though no independent confirmation of BloombergNEF Tier 1 bankability status was found in available sources. Tongwei, by contrast, is a much larger Chinese conglomerate headquartered in Chengdu, Sichuan, with deep vertical integration spanning high-purity polysilicon, solar cells, and modules. Its solar cell division has led global shipment rankings for eight consecutive years and reached approximately 150 GW of cell capacity by 2025. Tongwei has maintained BloombergNEF Tier 1 module manufacturer status continuously through 2025 and was named a Top Performer in the 2025 Kiwa PVEL Module Reliability Scorecard. In terms of institutional footprint, Tongwei is substantially larger and more bankable.

On the product side, Sunlike Solar offers monocrystalline and polycrystalline modules ranging roughly from 200 W to 600 W and is positioned primarily as a cost-accessible supplier for smaller commercial and residential projects, particularly in export markets. Its cell technology mix is not prominently documented in recent independent reviews, limiting confident technology claims. Tongwei markets its TW Solar modules across residential, commercial, and utility-scale segments, with TOPCon N-type technology driving the majority of its current portfolio - over 88% of its 2025 cell shipments from the top-five cell segment used TOPCon - and select bifacial dual-glass models carrying 30-year performance warranties.

For most buyers in 2025, Tongwei is the more defensible default: its BloombergNEF bankability, independent third-party scorecard recognition, and verified technology roadmap reduce project risk compared with Sunlike Solar, whose smaller scale and limited public review trail make it harder to assess with confidence. Sunlike may still suit buyers prioritizing lower upfront cost where bankability is less critical.
