Talking about the promotion model of residential grid-connected power generation system in the Chinese market solar street light-liters

The promotion model of residential grid-connected power generation system in the Chinese market: After China launched the subsidy policy for residential grid-connected power generation system in 2013, the local government also introduced corresponding incentive policies, making more and more photovoltaic enterprises invest more resources To develop and promote residential grid-connected power generation systems. At present, the more common methods in the market are as follows: 1. The house owner recognizes the advantages of the residential grid-connected roof system and the benefits it can bring in the future, and then goes to the supplier to purchase the system by himself, and asks the installation company to install it. Responsible for follow-up maintenance and directly enjoy the economic benefits brought by the system. The power generation is given priority to self-use, and the surplus power is connected to the grid. 2. Residential grid-connected power generation system suppliers look for suitable roof installations in the market, and reach an agreement with the homeowner. The system supplier will provide equipment, install and be responsible for subsequent maintenance, and the homeowner will provide the roof for a fee (rented as a roof). form, or share the power generation revenue with the system supplier in a certain proportion). The generated electricity is directly connected to the grid for sale. 3. Residential grid-connected power generation system supply to provide financial support to homeowners with suitable installed systems (such as the mode of installment payment). After the homeowner has passed the credit review, the system supplier will provide the system and install it. The homeowner has the right to use the system and enjoy the economic benefits brought by the power generation of the system, but it needs to report to the financial institution designated by the system supplier within a certain period of time (generally For the bank), the system lease fee is paid on time. When the lease expires, the homeowner can choose to become the system holder, renew the lease or terminate the contract. Due to the high initial installation cost of the residential grid-connected power generation system and the long capital recovery period, these two factors restrict the development of the market. Therefore, the innovation of business models has become an important factor in the promotion of the system. Residential photovoltaic power generation system example analysis and income accounting: According to the current policy, for the self-generated electricity of residential photovoltaics, the state will subsidize 0.42 yuan per kilowatt-hour of electricity, and the subsidy time limit is 20 years. In 2018, assuming that the municipal subsidy is 0.2 yuan per kWh (coming soon, the subsidy time limit is 5 years), the total subsidy for residential photovoltaic power generation can reach 0.72 yuan per kWh. If there is surplus power generated by the photovoltaic power generation system, the power company will purchase the surplus electricity unconditionally and pay the owner 0.45 yuan per kilowatt-hour of electricity.
