2 Huawei Micro Grid Solar Solution, Lighting the World New Energy, New Era, Huawei Micro Grid Solar Site Lights All Over the World Huawei micro grid solar solution has been widely applied in the areas without electricity such as remote villages, islands. The solution is based on the design concept of simple, efficient and reliable, replacing D.G. with PV power generation and energy storage system, which significantly reduces the cost of electricity. Huawei micro grid solar solution aims to improve the living standard of people, and it is an effective way to realize the electrifi cation of the area without electricity. Scenario 1:Remote village, sufficient solar energy, without grid or unstable grid, using D.G. to supply power, high cost of electricity. 01 Scenario 2:Island, sufficient solar ene rgy, without grid, using D.G. to supply power, high cost of electricity, high e nvironmental protection requirement, difficult fuel transporta tion. Scenario 3:Remote public facilities (schools, hospitals, etc.), replacing D.G. with PV power generation and energy storage system to reduce electricity cost. 02
