China to impose stricter necessities on PV manufacturing – pv journal International


The new provisions are meant to cut back overcapacity available in the market whereas choosing probably the most environment friendly applied sciences and merchandise.

China’s Ministry of Industry and Information Technology (MIIT) has submitted an modification to the “Photovoltaic Manufacturing Industry Normative Conditions” coverage for public session.

The coverage outlines necessities for brand spanking new development tasks and enlargement of all PV manufacturing parts, together with polysilicon, ingots, wafers, photo voltaic cells, modules, and inverters.

The necessities embody funding sourcing ratios, manufacturing format, technological course of, power consumption, useful resource utilization, sensible and inexperienced manufacturing, environmental safety, high quality administration, mental property safety, and occupational security.

Originally issued by MIIT in 2013, adopted by additional revisions in 2015, 2018, and 2021.

A key change will increase the minimal capital ratio for brand spanking new development and enlargement tasks within the photovoltaic sector to 30%. Previously, this requirement was 30% for polysilicon manufacturing tasks and 20% for different photovoltaic manufacturing tasks.

Industry analysts say this modification is a measure to curb funding impulses as a result of issues over overcapacity within the PV trade, lowered company debt and leverage ratios.

The revised requirements additionally enhance the effectivity necessities for photo voltaic cells and modules. The present capability should obtain photoelectric conversion efficiencies of at least 21.4%, 23.2%, and 25% for multicrystalline silicon cells, p-type monocrystalline silicon cells, and n-type monocrystalline silicon cells, respectively. The effectivity necessities for multicrystalline silicon modules, p-type monocrystalline silicon modules, and n-type monocrystalline silicon modules are set at at least 19.4%, 21.2%, and 22.3%.

In distinction, the 2021 model units effectivity necessities of at least 19% for multicrystalline silicon cells and 22.5% for monocrystalline silicon cells, and at least 17% and 19.6% for multicrystalline silicon modules and monocrystalline silicon. modules, respectively.

The revised doc additionally raises the necessities for degradation charges of photovoltaic modules and electrical energy value ranges for photovoltaic manufacturing tasks. For instance, the deterioration charges of p-type crystalline silicon modules don’t exceed 2% within the first 12 months, with a subsequent annual price of not more than 0.55%, and a cumulative 15% in 25 years. 12 months. Similarly, n-type crystalline silicon modules are capped at 1% within the first 12 months, 0.4% yearly thereafter, and 11% in 25 years. In addition, the common complete electrical energy consumption for cell tasks should be lower than 50,000 kWh/MW, and fewer than 70,000 kWh/MW for module tasks.

Energy consumption requirements have additionally been adjusted downward for a number of levels of manufacturing, together with polysilicon, ingots, wafers, crystalline silicon cells, and modules. Previous necessities specified a discount of particular power consumption to lower than 60 kWh/kg for present polysilicon tasks and complete power consumption to lower than 80 kWh/kg. Under the brand new requirements, these figures are adjusted to 46 kWh/kg and 60 kWh/kg, respectively, for present tasks, and 44 kWh/kg and 57 kWh/kg for the bag -ong development and enlargement tasks.

The new requirements additionally improve the water consumption necessities of photovoltaic manufacturing tasks. For instance, the water recycling price for polysilicon tasks has been adjusted from a minimal of 95% to 98%, and water consumption for wafer tasks should be at least 900 tons per million items, down from the earlier requirement of 1300 tons per million items. .

Industry observers say these increased requirements will speed up the elimination of outdated manufacturing capability.
