In a major advancement for high-voltage photovoltaic technology, the world’s first 2,000-volt photovoltaic (PV) empirical certification base has been inaugurated in Wenchang City, Hainan Province.
Operated by Datang Hainan Energy Development Co., Ltd., a subsidiary of China Datang Corporation Limited, this facility features comprehensive data collection and systematic performance-evaluation capabilities.
Currently, the PV industry is undergoing a high-quality transformation, but it lacks a unified standard for 2,000-volt technology promotion. As a future direction for large-scale ground power stations, 2,000-volt technology reduces cable usage and lowers electricity costs compared to traditional 1,500-volt technology. However, its long-term operational stability, device compatibility and adaptability to extreme environments require authoritative empirical support.
This facility will test whether PV products can operate stably for extended periods under conditions of high temperature, high humidity, and high salt fog. By establishing uniform test conditions and monitoring more than 20 parameters in real time, it can provide scientific outdoor operation data for essential equipment such as PV modules, inverters, and brackets. According to Datang Hainan Energy Development Co., Ltd., the PV industry is crucial for achieving the “dual carbon” goal, and empirical PV research is the key link that connects laboratory theory with actual applications at power stations. The company will leverage its advantages in clean energy in Hainan to promote the safe and reliable application of the 2,000-volt technology in high-temperature, high-humidity, and high-salt-spray environments.
