Governments' policy support for home photovoltaic and energy storage technology is mainly reflected in the following aspects:

Financial subsidies: The government encourages households to adopt solar photovoltaic power generation and energy storage systems through financial subsidies and other means to reduce the purchase and installation costs of users.

Tax incentives: The government can give tax incentives to home solar photovoltaic power generation and energy storage systems, reducing the burden on users.

Policy advocacy: The government advocates a low-carbon, environmentally friendly and energy-saving lifestyle through publicity and promotion, and encourages households to adopt solar photovoltaic power generation and energy storage systems to reduce dependence on traditional energy sources.

Regulatory policy: The government protects the rights and interests of users by developing regulatory policies and standards to ensure the safe, reliable and efficient operation of home solar photovoltaic power generation and energy storage systems.

Grid support: The government supports the access of household solar photovoltaic power generation and energy storage system through the construction of smart grid and other ways to realize the two-way flow of electricity and improve the utilization efficiency of the system.

In general, governments' policy support for household PV and energy storage technology has been strengthened, providing a strong guarantee for the popularization and promotion of the technology. At the same time, the government's regulation of technology and the formulation of standards are also conducive to improving the safe, reliable and efficient operation of the system and protecting the rights and interests of users.
