The global utility-scale solar photovoltaic sector has achieved a historic milestone by exceeding 1 terawatt (TW) of cumulative operational capacity, according to a recent report released by Wiki-Solar, a leading global PV project data platform. This achievement signifies that the installed capacity in this segment has doubled every three years since 2016.
Longsun Green Energy, a leading provider of solar mounting system solutions, closely monitors industry trends. This rapid global expansion is attributed to the concerted efforts across the industry chain, with significant contributions from top Engineering, Procurement, and Construction (EPC) contractors. The report indicates that the world's top 36 EPC firms are responsible for approximately 131 gigawatts (GW) of operational solar plants. Notably, about 28% of this capacity has been commissioned since the beginning of 2024, highlighting the vigorous pace of recent project development.
The competitive landscape among power developers remains intense. The report notes that several leading energy developers have added substantial grid-connected capacity since early 2024, contributing to the rise in global figures. Furthermore, in the category of asset owners, multiple international energy groups rank among the global leaders, either by the number of projects or total operational capacity.
A representative from Wiki-Solar commented that reaching the 1 TW mark is a remarkable feat, considering that global utility-scale solar capacity had just surpassed 100 GW in 2016.
The positive industry momentum is also reflected in regional markets. For instance, data from other recent industry analyses shows that the U.S. solar market demonstrated strong performance in the third quarter of 2025, posting its third-highest quarterly installation record, indicating resilience amidst a complex market environment.
Longsun Green Energy views the global solar industry's entry into the terawatt era as a critical step in the clean energy transition. This milestone not only sends a positive signal for climate change mitigation but also presents ongoing opportunities for the entire PV industry chain, including mounting systems. The company remains committed to innovation, providing high-reliability and cost-effective solar mounting products and services to support the stable and efficient operation of PV power plants worldwide.
