Modules below the Grade 3 threshold will be barred from production, sales and domestic project bidding, fundamentally reshaping the industry’s supply structure. At its investor briefing, JinkoSolar said the new standard tightens energy consumption and efficiency requirements across polysilicon and wafer production. LONGi Green, focusing on the BC route, noted the new standard sets the minimum entry efficiency at 23.5%, equivalent to 635W for the standard module size of 1134mm × 2382mm. Canadian Solar said the dual efficiency-cost framework will steer the industry away from destructive price wars that have affected the Chinese solar sector in recent years. Its TOPCon 3.0 modules deliver up to 670W and 24.8% in efficiency, with mass shipments starting in August 2026.
