According to estimates from the industry and securities firms, based on the scale of China's real estate and building area, the total space of distributed photovoltaic systems on rooftops in China may exceed 600GW, which is 2.36 times the current installed capacity of photovoltaics. The size of the photovoltaic building market is expected to reach trillions. After more than a decade of development, China's photovoltaic industry has established a mature industrial chain. With the current decline in photovoltaic product prices, the dual attributes of energy and building materials given to photovoltaic roofs, along with the implementation of national policies, will usher in a new period of rapid development for the industry.

Due to the instability of photovoltaic power generation and difficulties in grid scheduling, its integration into the grid is subject to certain limitations. Although the installed capacity has been increasing year by year, it has also resulted in the problem of power abandonment losses. One way to promote the healthy development of the distributed photovoltaic industry is through the development of corresponding energy storage and microgrids.
