What are the main differences between distributed photovoltaic power stations and large-scale ground photovoltaic power stations?

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

In the early years, when it comes to photovoltaics, many people may be a little unfamiliar, and they have no accurate knowledge 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. As one of the most competitive strategic emerging industries, photovoltaic power generation is developing at an immeasurable speed.

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

With the rapid development of photovoltaics, is there any difference between distributed photovoltaics and ground-based photovoltaic power plants? Briefly introduce to you:

Distributed photovoltaic power plants specifically refer to photovoltaic power generation facilities that are built near the user’s site and operate on the user side for spontaneous self-use, excess power to the Internet, and balance adjustment in the power distribution system.

Ground power stations refer to solar photovoltaic power stations that are connected to the public grid and share power supply tasks.

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 the suburbs or remote deserts and hills. Distributed photovoltaics emphasize on-site consumption, and are generally located in public buildings such as industrial plants, commercial buildings, agricultural facilities, municipalities, remote agricultural and pastoral areas, and islands. Distributed photovoltaic power plants involve more complicated issues in terms of project site selection and agreement signing, and various factors such as the integrity of the building owner, the safety and longevity of the building, and the risk of breach of contract need to be considered.

2. Electricity price

Large-scale ground power stations adopt 3 district benchmark electricity prices (the unified purchase and unified sales model): 0.90, 0.95, 1.0 yuan/kWh.

For distributed photovoltaic self-consumption and reverse transmission power, a subsidy of 0.42 yuan/kWh is given; the self-consumption power of distributed photovoltaic is based on the grid sales price + 0.42 yuan/kWh; the reverse transmission power of distributed photovoltaic is based on Purchase of local desulfurization electricity price (approximately 0.35~0.45 yuan/kWh) + 0.42 yuan/kWh; subsidy funds for distributed photovoltaic projects are transferred to power generation projects through grid companies, and investors can choose higher grid sales prices Distributed photovoltaic investment in the industrial park.

3. Project process

The project process of large-scale ground power stations in most provinces is to obtain roads, feasibility study reports and reviews, handle various supporting documents, project approvals, 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, prefecture-level or county-level departments for filing, and start construction, which is even more simplified in some places. During the construction of Nenghuanbao Power Station, in the early stage of the project, Nenghuanbao Company conducted detailed research and preparation work, including surveys on the location of power users, surveys on the use of land by power users, surveys on the factory buildings and roofs of power users, and electricity consumption. Research on the company’s electricity consumption, etc., to ensure stable work during the period; at the same time, provide companies with sufficient electricity and do a good job of surplus electricity online.
