Data speaks louder, upgrade grid-tie system to storage makes more money?
In recent years with the popularization of new energy, the scale of grid-tie system has increased significantly. However, due to the primitive power grid construction in a lot of areas, decreased or canceled Feed-in-Tariff, and low PV self-consumption rate, the phenomenon of feed-in power limitation and solar station abandonment has frequently occurred, resulting in resource waste, investment return reduction or even deficit. In view of this situation, our company put forward the energy storage AC-couple retrofit scheme and has been widely applied. Grid connected energy storage system can store the surplus power and improve the self-consumption ratio. It is applicable to the scenarios that PV power cannot be sold to utility grid, and self-use electricity price is higher than the feed-in price, or solar power generation and consumption are not in the same period.
