• Japan and Germany are pioneers in developing distributed solar and energy storage technologies

Japan and Germany have higher electricity prices and receive more regulatory support, thus establishing an early market that combines solar energy and energy storage technologies. The resulting innovation will benefit the world. Japan has a huge battery manufacturing industry, and the industry will continue to grow as the domestic market expands. In Germany, the business model innovation of solar energy storage technology has emerged. For example, consumers can rent a part of the power storage facilities for grid operators, and power companies such as StromBank set up community energy storage projects to support the development of rooftop solar energy. As forerunners, these two countries have also undertaken some negative influences. The lessons they have learned can ultimately benefit other countries.

• The US market is relatively fragmented, but in the long run, the combination of solar energy and energy storage technology may dominate.

California and Hawaii now have the highest solar energy penetration in the world, but the direct obstacle to the combination of solar energy and energy storage technology in the United States is the continuously lower natural gas price, which is the low cost of electricity generation. Despite this, U.S. start-up companies have embarked on the development of a complex combination of distributed solar energy and energy storage technology. Companies such as Tesla have also used the link between electric vehicles and energy storage technologies to recently launch the PowerWall residential battery system.

• China is prioritizing the development of power plant-scale solar projects, but there is still room for development with a combination of distributed solar energy and energy storage technologies.

China is currently drafting its “Thirteenth Five-Year Plan”. The latest guidance documents show that although the state supports the development of distributed solar energy facilities, the current focus of energy storage technology is still to ensure the reliability of large-scale energy storage. If rooftop and community solar power and energy storage technologies are further developed in China, they will begin in the highest-priced commercial and industrial sectors.

• India is ready to become a leader but still faces potential obstacles

India has more and more lead-acid battery companies committed to solving the grid power supply instability problem, and is ready to apply good domestic experience to foreign markets. However, with the development of the power industry and regulatory regulations, it is crucial that the central government and state governments implement strong policies to ensure that state-owned enterprises and the private sector can establish profitable and sustainable business models. Quality standards and quality assurance will also help support investments in distributed solar and energy storage technologies.

• Industry and policy makers need to start addressing the issues that may arise in the future from now on

The most pressing issues currently faced by the combination of solar energy and energy storage are the high cost of energy storage technology and the obstacles to regulatory regulation. However, other problems that form scale may also affect the development of the market, especially if we do not anticipate beforehand. Get ready and ready. Problems that can be foreseen at this stage include: impact on reputation due to low installation quality (it is recommended to establish uniform standards in the industry and implement certification systems to solve problems), and regulatory policies caused by poor integration of power grids (recommended through continuous investment pilot projects) , Widely share best practice knowledge to cope with), Lack of skilled workforce (suggested training program for installers and engineers), and cyber attacks, etc. (Proposal to establish alliances with IT industry and strengthen cooperation in grid integration). The discontinuity of trade barriers and supply chains may also hinder the development of this area, reduce the dependence on materials, and promote the research of alternative chemicals to ensure that technical costs continue to decline.
