Solar Panel Industry News: Record Installations, Technological Breakthroughs and Global Market Shifts
2023-04-19
Global Solar Panel Installations Set New Record, Surpassing 446 GW DC
2023 marked a historic milestone for global solar panel installations, with the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) reporting that global newly added photovoltaic capacity reached 446 GW DC, a dramatic increase from 236 GW in 2022. The global cumulative installed solar PV capacity also climbed to 1.6 TW, highlighting the accelerating adoption of solar energy worldwide as a core renewable energy source.
China emerged as the primary driver of this growth, with newly added solar panel installations surging to 235.5 GW DC, accounting for over 60% of the global total. This figure is nearly equivalent to the cumulative installed photovoltaic capacity in Europe, underscoring China’s pivotal role in the global solar industry. The country’s solar industry output value exceeded 1.75 trillion yuan, with production of polysilicon, wafers, cells, and modules all increasing by more than 60% year-on-year.
Other major markets also delivered strong performances: the United States added 33.2 GW of solar capacity, benefiting from the Inflation Reduction Act (IRA) which boosted domestic solar manufacturing and installations. Brazil installed 11.9 GW, cementing its position among the world’s top ten solar markets. In Europe, a total of 61 GW was installed, with Germany leading at 14.3 GW, followed by Spain (7.7 GW), Poland (6.0 GW), Italy (5.3 GW), and the Netherlands (4.2 GW).
Technological Breakthroughs: Efficiency Records Broken, N-Type Technology Takes Center Stage
2023 was a landmark year for solar panel technology, with continuous breakthroughs in efficiency and the widespread adoption of next-generation technologies. Perovskite-silicon tandem solar cells emerged as a key focus, with LONGi Green Energy achieving a world-record conversion efficiency of 33.9%, certified by the U.S. National Renewable Energy Laboratory (NREL). This breakthrough followed a series of incremental improvements throughout the year, including 31.8% in May and 33.5% in June, solidifying China’s leadership in this cutting-edge field.
N-type solar panels, including TOPCon and HJT technologies, became the mainstream in mass production, replacing traditional P-type panels. Tongwei Co., Ltd. set a world record for HJT mass production efficiency at 26.18%, with module power entering the 730W+ era. Trina Solar further pushed the envelope, achieving a maximum HJT module power of 776.2W and breaking the 27% efficiency barrier multiple times. For TOPCon technology, Tongwei’s TNC pilot line reached 25.8% efficiency, with mass production exceeding 25.5%, while Trina Solar’s i-TOPCon technology also achieved significant improvements in efficiency and power.
Global Market Dynamics: China Dominates Supply Chain, Price Wars and Export Trends
China’s dominance in the global solar panel supply chain continued in 2023, with Wood Mackenzie reporting that China will hold over 80% of the world’s polysilicon, wafer, cell, and module manufacturing capacity from 2023 to 2026. This dominance is driven by advanced technology, low costs, and a complete supply chain, with a Chinese-manufactured solar module costing 50% less than those produced in Europe and 65% less than in the United States.
Despite strong global demand, the industry faced challenges from overcapacity and price wars. In 2023, global solar module inventory reached 150 GW, leading to a sharp decline in prices: monofacial and bifacial solar module prices fell by 26% and 31% respectively. This overcapacity primarily affected older production lines producing low-efficiency P-type products, with demand for P-type cells declining significantly and expected to account for only 17% of supply by 2026.
China’s solar panel exports remained robust, with total exports of silicon wafers, cells, and modules reaching 490.66 billion US dollars. While this represented a 5.58% year-on-year decrease in export value, export volume increased by 25.56% to 1818.27 million tons, reflecting the impact of lower module prices. Europe remained China’s largest overseas market, accounting for 41.14% of exports, while “Belt and Road” countries such as Saudi Arabia, Pakistan, and South Africa saw exponential growth in imports, becoming strategic pillars for China’s solar exports.
