JinkoSolar has delivered 1GW of its high-efficiency N-type TOPCon bifacial modules for Phase 1 of the Delingha solar-storage project in Qinghai. Built to handle harsh desert conditions like extreme temperature shifts, strong UV radiation, and sandstorms, these modules are powering reliable clean energy in the Qaidam Basin.
Thanks to an 85% bifaciality rate and the natural reflectivity of desert sand, these modules generate 3–5% more power from the rear side compared to standard bifacial panels. They also have just 1% first-year degradation and only 0.4% annual decline, along with a low temperature coefficient of -0.29%/°C—ensuring solid performance even in over 60°C surface heat.
This project is the first in Western Qinghai to combine solar PV with thermal energy storage, enabling round-the-clock power supply. Once complete, it will produce 1.8 billion kWh annually and cut 650,000 tons of CO₂ emissions.
