The difference between distributed photovoltaic power station and ground photovoltaic power station

In the early years, when it comes to photovoltaic photovoltaics, many people may be a little unfamiliar, and they have no accurate understanding of whether photovoltaic power generation is good or not. However, with the development of science and technology in recent years, photovoltaic power generation has gradually entered the public’s field of vision and is well known by people. As one of the most competitive strategic emerging industries at present, photovoltaic power generation is developing rapidly at an inestimable speed.

Do you know the difference between distributed photovoltaics and ground photovoltaics?

In the early years, when it comes to photovoltaic photovoltaics, many people may be a little unfamiliar, and they have no accurate understanding of whether photovoltaic power generation is good or not. However, with the development of science and technology in recent years, photovoltaic power generation has gradually entered the public’s field of vision and is well known by people. As one of the most competitive strategic emerging industries at present, photovoltaic power generation is developing rapidly at an inestimable speed.

When it comes to the principle of photovoltaic power generation, it is relatively simple and easy to understand. It is a technology that directly converts light energy into solar energy by using the photovoltaic effect of the semiconductor interface. According to relevant data, as of January-August 2019, the newly installed photovoltaic capacity was 14.95GW. The International Energy Agency (IEA) said that it is expected that the global installed capacity of renewable energy will reach 200GW in 2019, a year-on-year increase of 12%. The speed is the highest since 2015.

With the rapid development of photovoltaics, is there any difference between distributed photovoltaics and ground photovoltaic power plants? Xiaobian can briefly introduce to you:

Distributed photovoltaic power station refers specifically to photovoltaic power generation facilities constructed near the user site, and the operation mode is characterized by self-generated self-use on the user side, excess electricity connected to the Internet, and balanced adjustment in the power distribution system.

The ground power station refers to the solar photovoltaic power station that is connected to the public grid and jointly undertakes the power supply task.

Distributed photovoltaic power plants differ from large-scale ground photovoltaic power plants in the following aspects:

1. Project location

Large-scale ground photovoltaic power plants are generally located in suburbs or remote deserts and hills. Distributed photovoltaics emphasize on-site consumption, and are generally located in industrial plants, commercial buildings, agricultural facilities, municipal and other public buildings, remote farming and pastoral areas, and islands. Distributed photovoltaic power plants involve more complex issues in project site selection and agreement signing, and various factors such as the integrity of the building owner, the safety and life of the building, and the risk of default need to be considered.

2. Electricity price

Large-scale ground power stations adopt 3 regional benchmark electricity prices (uniform purchase and sales model): 0.90, 0.95, and 1.0 yuan/kWh.
For distributed photovoltaic self-consumption and reverse transmission, a subsidy of 0.42 yuan/kWh is given; distributed photovoltaic self-consumption is based on the grid sales price + 0.42 yuan/kWh; distributed photovoltaic reverse transmission is based on The purchase of local desulfurization electricity price (about 0.35-0.45 yuan/kWh) + 0.42 yuan/kWh; the subsidy funds for distributed photovoltaic projects are transferred to power generation projects through power grid companies, and investors can choose to sell electricity from the grid with a higher price. Industrial parks for distributed photovoltaic investments.

3. Project process

The project process of large-scale ground power stations in most provinces is to obtain road signs, feasibility study report and review, handle various supporting documents, project approval, and start construction. At present, some provinces and cities have been simplified to prefecture-level or county-level departments for filing, handling various supporting documents, and starting construction. The process of distributed photovoltaic projects is to handle documents, record with prefecture-level or county-level departments, and start construction, and some places are even more simplified. During the construction of Nenghuanbao Power Station, at the initial stage of the project, Nenghuanbao Company carried out detailed research and preparations, including research on the area of ​​electricity consumption enterprises, research on land use by electricity consumption enterprises, research on workshops and roofs of electricity consumption enterprises, and electricity consumption. Research on the power consumption of enterprises, etc., to ensure stable work during the period; at the same time, provide sufficient power for enterprises, and do a good job of connecting surplus power to the Internet.

As a new energy enterprise, Nenghuanbao has taken practical actions to help the development of my country’s real economy, save electricity costs for enterprises, improve market competitiveness, provide individuals with multiple types and all-round new energy transaction services, and promote the development of the environmental protection industry. Humans and the environment win-win!
