China on July 2 approved and published three mandatory national standards
setting energy‑consumption limits and efficiency thresholds across the
photovoltaic value chain. The Ministry of Industry and Information Technology,
jointly with the National Development and Reform Commission and SAMR, issued:
Energy Consumption Limit per Unit Product for Monocrystalline Silicon; Energy
Efficiency Limit Values and Efficiency Grades for Crystalline Silicon
Photovoltaic Modules and Inverters; and Energy Consumption Limit per Unit
Product for Polysilicon and Germanium. The standards cover key links including
polysilicon, wafers, modules and inverters, impose graded energy and efficiency
metrics to curb high‑energy, low‑efficiency capacity, and introduce a coupled
environmental‑stress degradation rate metric for modules. Industry bodies will
accelerate promotion and implementation. Authorities say the rules aim to
strengthen China’s PV industry competitiveness and support the country’s green
low‑carbon transition and dual‑carbon targets.
