Recently, a reporter learned from China Electric Power Construction Corporation that the Luzenfa Solar Photovoltaic Project, the first hydropower and solar power complementary project in Zambia, has officially been connected to the power grid for operation. The project has a total installed capacity of 27 megawatts and adopts the "photovoltaic priority, hydropower regulation" mode, achieving efficient linkage of the hydropower and solar power complementary system.

The project site is a mountainous terrain, facing challenges such as difficulty in controlling photovoltaic shading. The project team implemented the "one slope, one plan" approach, ensuring the maximum utilization of land while achieving uniform tilt angles for the supports and strictly controlling the verticality deviation of the columns within ±0.5 degrees. As a result, there was no shading throughout the 9-15 hours in the factory area. In addition, the project innovatively adopted techniques such as zone-based flow-line construction, reducing the overall construction period by nearly 30%. After full production, it will effectively alleviate the local power supply shortage, help Zambia optimize its national energy structure, and promote the development of renewable energy.

Stainless steel bolts manufactured and sold by Goshen Hardware are applicable for hydro-solar complementary projects.
