The surge in China’s solar power generation from 2023 to 2025 can be attributed to record capacity additions, rapidly falling technology costs, and accelerated project deployment. According to international energy agencies, China dominated global solar installations during this period, with annual additions reaching unprecedented levels and substantially expanding the country's installed base. A large portion of this growth stemmed from the completion of delayed projects, which had been postponed due to pandemic-related disruptions and supply chain challenges in earlier years.
