It is estimated that China will build about 50 distributed energy microgrid demonstration projects by 2025, forming a distributed microgrid technology system, market system and management system.
In China, the microgrid projects that have been completed can be divided into island microgrids, remote areas microgrids, and urban area microgrids based on their geographic locations.
It is comprised of multiple distributed energy resources (DERs), such as solar panels, wind turbines, energy storage systems, and traditional generators, that can generate, store, and distribute energy within a defined geographic area. . Microgrids are small-scale power grids that operate independently to generate electricity for a localized area, such as a university campus, hospital complex, military base or geographical region. [1] It is able to operate in grid-connected and off-grid modes.

Solar PV capacity in Ethiopia has almost tripled in the past five years. However, 14 MW of solar PV systems has been installed up to now, counting for 0.3% of the Nation's total energy capacity. Ethiopia's solar capacity is expected to increase in the coming years with the number of ongoing solar PV projects.
For effective and efficient utilization of solar energy in Ethiopia, the following recommendations and policy implications will be useful: • Government should subsidize the cost of importation of Renewable Energy Technologies (RET) most especially solar PV to bring down the high cost in Ethiopia, and make it affordable.
