Hopewind Powers China’s largest standalone environmental desert control PV project


Hopewind has significantly contributed to the construction of China’s largest standalone environmental desert control photovoltaic (PV) project. Situated in the Kubuqi Desert, Mengxi Base, this 2GW project is groundbreaking in its scale and impact.

Project Significance

The Kubuqi Desert project is crucial for improving the ecological environment of the “Jiziwan” basin of the Yellow River and the Kubuqi Desert. It sets a valuable precedent for the application of PV sand control technology in desert areas. With an installed capacity of 2GW, the project aims to rehabilitate and control 6,667 hectares of desert, reducing annual sand transport to the Yellow River by about 2 million tons.

Environmental and Economic Benefits

This project is expected to generate an average of 4.1 billion kWh annually, saving approximately 1.23 million tons of standard coal and reducing carbon dioxide emissions by about 3.19 million tons each year. Moreover, under the PV panels, forage and medicinal plants are cultivated, and livestock such as chickens and sheep are raised. The panels help block light and wind, cool the land, reduce water evaporation, and increase soil moisture, creating a sustainable habitat for both vegetation and animals.

Technological Advancements

The project utilizes 5,604 sets of Hopewind inverters and 6 sets of Static Var Generators (SVGs). Hopewind’s HSHV350K, the world’s most powerful string inverter with a maximum output of 385kW, demonstrates exceptional performance even in harsh climatic conditions. The inverter operates efficiently at temperatures up to 45°C without derating, thanks to its IP66 ingress protection. It also has a low short-circuit ratio (SCR) of 1.03, indicating excellent adaptability to weak grids. Safety features include AFCI, AC/DC terminal temperature detection, high-precision string detection, intelligent I-V curve scans, and DC intelligent shutdown, all of which enhance operational efficiency and ease of maintenance.

Enhanced Stability and Efficiency

In addition to supplying all photovoltaic inverters, Hopewind provided six sets of 35kV direct-mounted indoor water-cooled SVGs to enhance the operational stability and efficiency of the station equipment.

Transforming the Desert

The Kubuqi Desert, once known as the “Sea of Death,” has been transformed into a vibrant energy oasis, lighting up thousands of households as night falls.

Hopewind’s involvement in this pioneering project underscores its commitment to technological innovation and sustainability, paving the way for future advancements in desert control and renewable energy.
