4 FAQs about [China Solar Collector Retest Requirements]
What are China's changes to photovoltaic manufacturing standards?
SUN KAIFANG/FOR CHINA DAILY China's Ministry of Industry and Information Technology has announced revisions to photovoltaic manufacturing industry standards, addressing current challenges like businesses' repetitive expansion of low-level production capacity and falling profitability, to promote the PV industry's healthier development.
How much solar power did China install in 2024?
On the application side, China installed 102.48 gigawatts of PV stations in the first half of 2024, marking a 30.7 percent year-on-year increase. However, the growth rate slowed, reflecting a contraction in downstream demand.
What are the new photovoltaic industry guidelines?
The revised guidelines encourage photovoltaic companies to focus on technological innovation, product quality improvement and production cost reduction, rather than merely expanding capacity, MIIT said. In recent years, the PV industry has faced significant internal competition.
How did China's PV industry perform in 2024?
Data from the China Photovoltaic Industry Association revealed that despite a more than 32 percent year-on-year increase in the production of silicon wafers, cells and modules in the first half of 2024, the domestic PV manufacturing output value (excluding inverters) fell by 36.5 percent to approximately 538.6 billion yuan ($74.3 billion).
