Application scenarios of distributed photovoltaic grid-connected systems

At present, my country's distributed photovoltaic grid-connected power generation systems are mainly concentrated in developed areas with relatively tight power consumption and remote areas with unstable public power grids. They are more suitable for application in the following industries:

1. Factory buildings in the industrial field: Especially factories with large electricity consumption and high online shopping prices usually have large roof areas and open and flat roofs, which are suitable for installing photovoltaic arrays; due to the large power load, distributed photovoltaic grid-connected systems can be consumed locally. , offset part of the electricity consumption of online shopping and save users’ electricity consumption.

2. Commercial buildings:
Distributed solar photovoltaic for commercial buildings

Similar to the effect of an industrial park. The difference is that most commercial buildings have cement roofs, which are more conducive to the installation of photovoltaic arrays; however, the aesthetics of the building are often required. According to the characteristics of commercial buildings, office buildings, hotels, conference centers, resorts and other service industries, user load characteristics are generally high during the day and low at night, which can better match the characteristics of photovoltaic power generation.

3.Agricultural facilities:
Distributed solar photovoltaic for agricultural facilities

Photovoltaic roof areas are large in rural areas, including rooftops of self-owned residences, vegetable greenhouses, fish ponds, etc. Rural areas are often at the end of the public power grid, where power supply is difficult to guarantee and power quality is poor. The construction of rural distributed photovoltaic systems can improve the power guarantee rate and power quality.

4. Municipal and other public buildings:
Due to unified management specifications, relatively reliable user loads and business behavior, and high enthusiasm for installation, public buildings such as municipalities are also suitable for the centralized connection construction of distributed photovoltaics.

5. Remote agricultural and pastoral areas and islands:
Due to the distance from the power grid, remote agricultural and pastoral areas and millions of people without electricity in Tibet, Qinghai, Xinjiang, Inner Mongolia, Gansu, Sichuan and other provinces, off-grid photovoltaic systems or photovoltaic and other energy complementary microgrid power generation systems are very suitable for these areas.

Distributed photovoltaic grid-connected systems are widely used in education, telecommunications, petrochemicals, transportation, military and other industries.
