In order to reduce the cost of solar power generation facilities, departments and enterprises of various countries provide incentive measures, and more and more users deploy solar power facilities to save electricity costs. Today, the deployment of solar battery energy storage systems is accelerating, and it has become an important part of the booming solar industry.

Because the intermittent power supply of solar power generation will adversely affect the operation of the power grid, Hawaii does not allow newly built solar power facilities to send its excess power to the power grid. Hawaii began to restrict the deployment of solar power facilities that directly access to the power grid in October 2015. It also became the first regulatory agency in the United States to take restricted measures. In order to ensure that they store excess power and use it during the peak demand, instead of directly transporting the power to the power grid, many customers who operate solar power facilities in Hawaii have deployed a battery energy storage system. Therefore, the relationship between solar power generation facilities and battery energy storage systems is now closer.

Since then, electricity prices in some US states have become more complicated, partly because of preventing the power of solar power facilities from exporting to the power grid at an inappropriate time. Although the additional cost of deploying battery energy storage systems will make the financial return of solar power generation facilities lower than the direct access to the power grid, the battery energy storage system provides additional control capabilities and flexibility for the power grid. More importantly, the battery energy storage system will become the integral part of most solar power generation facilities in the future.

For a long time, the battery energy storage system provider has been supporting the development of solar energy storage projects, and some large solar power generation facilities installations have begun to provide their customers with their own battery products in the past few years. These companies said that with the significant increase in market share of solar energy storage projects, the lithium -ion battery energy storage system with long working life and good deployment performance is more attractive to users. The marketing, information transmission, and industry influence of these companies will increase the consciousness of consumers, enterprises, and departments. When the main developers in the solar power generation field are participating in battery production. Their smaller competitors are also taking action to ensure that they will not lag behind others.
