## Summary

Longi Solar, officially LONGi Green Energy Technology Co., Ltd., is a Chinese manufacturer founded in 2000 and headquartered in Xi'an, Shaanxi. It has held BloombergNEF Tier 1 status continuously - confirmed through Q3 and Q4 2025 and reinforced in Q1 2026 when the company simultaneously earned Tier 1 recognition in energy storage, a double classification very few manufacturers hold. With roughly 67.5 GW of modules shipped in 2024 and an internal target approaching 80 GW for 2026, LONGi ranks among the largest PV module producers on the planet. Techwise Solar Technology Co., Ltd. is also a Chinese manufacturer, operating at approximately 1 GW of annual production capacity. It holds standard industry certifications - TUV, CE, ISO, and CGC - and functions primarily as an ODM/OEM supplier to larger Tier 1 brands, but has not earned an independent BloombergNEF or PV-Tech bankability designation in its own right. By any institutional measure, LONGi carries a substantially stronger global standing.

LONGi's product strategy is built around its proprietary HPBC 2.0 back-contact cell technology, delivered through the Hi-MO 9 series for utility-scale and commercial ground-mount projects - reaching up to 670 W and 24.8% efficiency in mass production - and the Hi-MO X10 Guardian lightweight module for commercial and industrial rooftop systems. A newer HIBC line, combining heterojunction with back-contact architecture, entered mass production in 2025 and pushes module efficiency above 25.9%. The EcoLife residential range covers full-black and bifacial configurations for homeowners. Techwise Solar markets panels under its Sun-Pursuit label in PERC, TOPCon, and bifacial glass formats across cell sizes from 166 mm to 210 mm, primarily addressing volume B2B buyers and integrators seeking flexible OEM sourcing rather than end-customers prioritizing long-term brand support.

For most international buyers - whether residential homeowners, commercial integrators, or utility-scale developers - LONGi is the more defensible default. Its unbroken Tier 1 bankability record, industry-leading cell efficiency, and global service network reduce long-term project risk and simplify financing negotiations. Techwise Solar can be a reasonable fit for cost-sensitive B2B procurement or OEM sourcing where brand recognition is secondary, but the absence of an independent bankability rating is a meaningful gap whenever project lenders or resale value enter the picture. These two manufacturers are not interchangeable in risk profile, even if individual datasheet figures occasionally appear similar.
