Frequently Asked Questions
How much solar capacity does China install annually?
China installed 217 GW of new solar capacity in 2024, the world's largest annual installation. This includes 130 GW of distributed solar (rooftop) and 87 GW of utility-scale. China's cumulative solar capacity exceeded 800 GW, accounting for 40%+ of global installed solar capacity.
How low have solar module prices fallen?
Solar module prices in China fell below RMB 0.8/W (USD 0.11/W) in 2024, a 60%+ decline from 2022 peaks. This price crash was driven by massive overcapacity in silicon wafer and cell production. At these prices, solar generates electricity at USD 0.02-0.03/kWh, cheaper than coal in most locations.
Which solar technology dominates: TOPCon or HJT?
N-type TOPCon dominates with 70%+ of new cell capacity in 2024 due to lower cost and compatibility with existing PERC production lines. HJT (Heterojunction) has higher efficiency ceiling (26%+ vs 25%+ TOPCon) but higher cost. BC (Back Contact) cells, pioneered by LONGi, are emerging as a third option with 26%+ efficiency.
How are Chinese solar companies responding to US/EU trade barriers?
Chinese companies are: (1) building factories in Southeast Asia (Vietnam, Thailand, Malaysia), (2) establishing US manufacturing (JA Solar, Trina Solar in the US), (3) developing non-Chinese supply chains for the US market, and (4) focusing on emerging markets (Middle East, South America, Africa) with fewer trade restrictions.
What is the solar overcapacity situation in China?
China's solar manufacturing capacity significantly exceeds demand: module capacity is 800+ GW vs 600+ GW global demand, wafer capacity is 700+ GW, and cell capacity is 600+ GW. This overcapacity has driven prices to unsustainable levels, causing losses for many manufacturers and triggering industry consolidation. Only the top 5-6 companies are expected to survive the shakeout.
