The first stage: starting stage -stable and slow photovoltaic industry development

In the early stage of development, that is, decades ago, at that time, optical power generation was still a relatively new concept. The system cost was extremely high and the economy was very low.

The second stage: the rise of the photovoltaic industry -the start of energy storage

With the decline in the cost of photovoltaic systems and large -scale applications, the installation volume of photovoltaic systems has increased rapidly. The demand for power has grown rapidly, and the government has continuously provided financial subsidy support. Because the battery cost is still very high at this stage, the energy storage system has grown slowly.

Third stage: explosion point -energy management system

The amount of installation of photovoltaic systems has developed rapidly, which puts pressure on the public power grid system and quickly reached the limit. Therefore, government subsidies fell quickly. In this context, the plan for household energy storage and anti -countercurrent is widely used in the needs of new energy grid management and increasing self -use rate. Therefore, more intelligent and grid -friendly energy management systems are gradually becoming more and more popular; the energy management system includes virtual power plants, microfil network systems, frequency control, and FCAS in specific markets such as Australia, RCR control in Germany, Japan's Japan, Japan HEMS systems and IEEEEEEEEE2030.5 in the United States.
