截至7月底，中国光伏发电装机容量首次超过煤电，成为全国第一大电源1。光伏发电装机在全国发电装机总容量中的占比达到31.5%1。这一转变标志着中国能源结构发生了历史性变化，但专家指出其内涵更为复杂。
从实际发电贡献看，光伏的主导地位并未完全确立。今年上半年，全国煤电发电量为2.5万亿千瓦时，占总发电量的比重仍为49.7%1。尽管年内煤电发电量占比历史性跌破50%1，但今年1-7月光伏发电在全社会用电量中的占比仅为13%1。这反映出光伏虽然装机容量领先，但年利用小时数远低于煤电1。前7月全国每用8度电就有超过1度来自光伏1。
专家认为，这一转变代表中国电力系统运行机制的深刻调整。华北电力大学能源互联网研究中心副主任王永利指出，"光伏装机超过煤电不是宣告煤电时代结束，而在于中国电力系统开始从单一主力电源转向多元电源协同支撑"1。煤电正在从发电主力向灵活调节电源转变，与新能源协同运行1。国家发改委政策研究室副主任李超表示，煤电要"让其加减速都更快、怠速稳得住、高低速都更省油"1。
展望未来，光伏产业仍有巨大投资空间。未来5年，中国光伏产业投资预计超过2万亿元人民币1。
China's photovoltaic power generation capacity has exceeded coal-fired power for the first time as of the end of July, becoming the nation's largest electricity source and signaling a fundamental transformation in the country's energy landscape 1. Solar capacity now accounts for 31.5 percent of total installed generating capacity nationwide 1, though its annual utilization hours remain significantly lower than coal power.
Despite this milestone in installed capacity, solar's actual contribution to electricity supply tells a more nuanced story. During the first seven months of the year, solar accounted for just 13 percent of total electricity consumption across society 1, while coal-fired generation supplied 49.7 percent of total power output in the first half of the year 1—marking the first time coal's share has historically fallen below 50 percent 1. On average, more than one of every eight kilowatt-hours consumed nationally comes from solar 1.
Energy experts emphasize that this transition does not mark the end of the coal power era, but rather a fundamental restructuring of China's electricity system. According to Wang Yongli, deputy director of the Energy Internet Research Center at North China Electric Power University, "The fact that solar capacity exceeds coal power does not herald the end of the coal power era, but rather signals that China's power system is transitioning from relying on a single dominant electricity source to coordinating multiple diverse sources" 1. Coal-fired power is shifting from serving as the primary source of generation toward becoming a flexible adjustment resource that operates in coordination with renewable energy sources 1. Looking ahead, China's solar industry is expected to attract investment exceeding two trillion yuan over the next five years 1.
