wind solar hybrid system

Compared with the grid-connected power generation system, the cost of the off-grid power generation system is higher than that of the grid-connected power generation system because it needs to be equipped with a battery as an energy storage device. The size of the power generation system generally needs to be smaller than that of the grid-connected system, and the power generation efficiency is low, but the off-grid power generation system exists independently from the national grid, which can save the cable lines connected to the power grid, so that the length of the cables used in the entire system is much less than grid-connected power generation system, so the off-grid power generation system can be installed faster and more conveniently on site.
