China Solar Energy - Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026-2031)

China solar energy market size in 2026 is estimated at 1.41 Thousand gigawatt, growing from 2025 value of 1.23 Thousand gigawatt with 2031 projections showing 2.85 Thousand gigawatt, growing at 15.03% CAGR over 2026-2031. This report is Segmented by Technology (Solar Photovoltaic and Concentrated Solar Power), Grid Type (On-Grid and Off-Grid), and End-User (Utility-Scale, Commercial and Industrial, and Residential). The Market Sizes and Forecasts are Provided in Terms of Installed Capacity (GW).

China Solar Energy Market Trends and Insights

Record-Low Module Prices Drive LCOE Competitiveness

Module prices fell to RMB 0.75/W in early 2024 after China’s manufacturing capacity ballooned to 861 GW against global demand of 600 GW. Cost leadership pushed solar LCOE below coal in more than 25 provinces, prompting developers to accelerate gigawatt-scale projects without subsidies. Industry consolidation is inevitable, yet leading firms such as LONGi and JinkoSolar benefit from N-type TOPCon lines that preserve margins.

14th Five-Year Plan Targets Accelerate Capacity Expansion

The 14th Five-Year Plan set a 1,200 GW renewable goal by 2025, with solar expected to add more than 600 GW, spurring provincial quotas of 50 GW in Shandong, 40 GW in Henan, and 35 GW in Jiangsu. Bundling mandates that pair every 1 GW of solar with 200 MW of coal or 100 MW of storage raise project capital costs by up to 20%, channeling market share toward vertically integrated developers able to internalize key inputs.

Grid Congestion Constrains Northwestern Capacity Utilization

Curtailment has subsided nationally but remains above 5% in parts of Xinjiang and Gansu. The Qinghai-Henan ±800 kV UHVDC corridor evacuated 8 GW of clean power in its first year but averaged only 60% utilization because receiving grids saturate during off-peak demand. Mandatory two-hour storage for every 10 MW of new capacity adds USD 0.015 per kWh, squeezing project returns in regions where midday wholesale prices drop below USD 0.03 per kWh.

Other drivers and restraints analyzed in the detailed report include:

• Corporate PPA Market Transforms Energy Procurement
• Mandatory Rooftop PV Policies Drive Distributed Growth
• Overseas Trade Barriers to Chinese Modules

Segment Analysis

China's solar energy market size for photovoltaic technology stood at 1,223.24 GW in 2025, equaling 99.45% of total installed capacity, while CSP reached 6,760.76 MW. N-type variants, TOPCon, and heterojunction expanded their domestic shipment share from 25% in 2023 to 45% in 2024, encouraged by LONGi's world-leading 27.09% cell efficiency and Trina's 26.5% milestone. CSP is slated to grow at a 18.95% CAGR, buoyed by a feed-in premium of CNY 1.5 (USD 0.21) per kWh that cushions its three-times-higher capex compared with.

Perovskite-silicon tandems touched 33.9% laboratory efficiency in 2024, and pilot lines targeting mass production by 2027 suggest future cost parity with current mono-crystalline units. Hybrid CSP-PV projects under construction in Qinghai, pairing 200 MW of thermal storage with 1 GW of PV, promise four-hour post-sunset dispatch and 2 percentage-point higher IRRs versus standalone PV. Off-grid PV remains below 9% of yearly additions but serves strategic niches such as telecom base stations and border surveillance, where diesel displacement justifies premium pricing
