How residents choose grid-tie solar system or off-grid solar system

May 06 , 2022

The grid-tie solar system needs to be connected to the grid, and is suitable for areas covered by the grid and stable power supply. The main purpose of installing a residential grid-tie solar system is to save energy and reduce consumption, increase the proportion of green energy, and reduce pollution. Based on the requirements for the installation site of the residential grid-tie solar system, it can be found that the urbanized rural areas are more suitable for the promotion of the residential grid-tie solar system. There are few high-rise buildings around (there is not much shading). There are many high-rise buildings in the city, which is difficult to realize, but the villa area is still suitable for promoting the grid-tie solar system for residents.


The off-grid solar system for residents is mainly used to solve the problem of people's domestic electricity consumption in areas without electricity or in areas with severe power shortage. It is more applicable in Africa, island countries and some remote areas with low grid coverage. Compared with the traditional diesel power generation system, the initial investment cost of the off-grid solar system is higher. At the same time, the follow-up maintenance is more difficult than the diesel power generation system. Therefore, the coverage of the current residential off-grid power generation system is not as wide as that of the diesel power generation system. However, the advantages of residential off-grid solar system lie in energy saving and consumption reduction, government policy support, and no subsequent consumables. In view of these advantages of residential off-grid solar system, its market potential is better than that of diesel power generation systems.
