Recently, Wang Bohua, vice chairman and secretary-general of China Photovoltaic Industry Association, introduced that in the first half of 2019, China's new PV installations were 11.4GW. Among them, the centralized installation of new power plants is about 6.8GW; the newly installed distributed photovoltaics is about 4.6GW.

Industry status analysis

Although due to policy reasons, China's new PV installations in the first half of 2019 fell by more than 50% compared with the same period of last year, the industry generally believes that the new PV installations in China are expected to exceed 40GW this year.

In other words, in the second half of this year, the Chinese PV market will have 30 GW of demand and focus on a short period of time.

Centralized power station

Make full use of the rich and relatively stable solar energy resources in the desert area to build large-scale photovoltaic power stations, and connect high-voltage transmission systems to supply long-distance loads.

The main advantage:

1. Power station location:

The location is more flexible, the PV output stability is increased, and the positive peaking characteristics of solar radiation and power load are fully utilized to play the role of peak clipping.

2. Operation mode:

It is more flexible, and it is more convenient to perform reactive power and voltage control than distributed PV. It is easier to participate in grid frequency adjustment.

3. Construction period:

The cycle is relatively short, the environment adaptability is strong, and there is no need for raw materials such as water source and coal-fired transportation. The operating cost is low, and it is easy to centrally manage. It is limited by space and can be easily expanded.

Distributed photovoltaic

Mainly based on the surface of the building (such as the roof of the factory), not only solve the problem of power consumption of the user, but also realize the compensation and delivery of the power supply difference through the grid connection.

Its main advantages:

1. The photovoltaic power supply is on the user side, and the power supply is supplied to the local load, which is regarded as the load, which can effectively reduce the dependence on the power supply of the power grid and reduce the line loss.

2. Make full use of the surface of the building, and the photovoltaic cell can be used as a building material at the same time, effectively reducing the floor space of the photovoltaic power station.

Where is the explosion?

In recent years, with the strong support of national policies and the joint efforts of industry enterprises, China's photovoltaic industry has achieved remarkable results: China has become the world's largest producer of photovoltaic products and the largest installed country of photovoltaic installations. There are world-class installation processes in both centralized and distributed PV.

Compared with distributed photovoltaic power, centralized power plants have larger individual scales and larger investments. Distributed PV is more widely used and has less investment. It is more suitable for industrial and commercial enterprises, and uses its own factory roof for distributed photovoltaic installation, saving power operation costs.

Xiaobian firmly believes that the development potential of the photovoltaic industry is huge, and the explosion point in the second half of the year is also inevitable. Let us wait and see.
