Guangdong has built 15 photovoltaic power plant projects

A few days ago, the “Dongguan Photovoltaic Application Development Research Report” was published. At present, the total scale of the photovoltaic power plant project in our city is 46.32MW, and the total installed capacity in 2017 is expected to exceed 3GW.

The distribution map of photovoltaic power generation projects in Dongguan surfaced. Recently, the City Economic and Trade Bureau issued the "Diamond Photovoltaic Application Development Research Report" (hereinafter referred to as the "Report"). The city has built 15 photovoltaic power station projects with a total investment of 553 million yuan and a total size of 46.32MW, accounting for the country's total installed photovoltaic power. At 0.67%, it is tentatively estimated that by 2017, the total installed PV capacity in the city will exceed 3GW.

At present, of the 15 photovoltaic power generation projects, there are 2 projects that have been connected to the grid for power generation, and the cumulative power generation is about 2 million kWh. The photovoltaic power generation application projects that have been built or under construction are mainly concentrated in Humen, Mayong and Songshan Lake, and there are a small number of distributions in Nancheng, Shijie, and Dongcheng.

The cost of photovoltaic power generation continues to decline

The "Report" disclosed that at present, the city has already built and under construction photovoltaic power generation application projects include solar roof power generation in Xinyi Industrial Park and Vanke Residential Industrialization Base, solar photovoltaic building integration projects, mainly concentrated in Humen, Ma Yong, Songshan Lake, a small amount Distributed in Nancheng, Shijie and Dongcheng.

Regarding the prospect of photovoltaic power generation, the "Report" pointed out that under the support of technological innovation and industrial chain optimization, the cost of photovoltaic power generation has continued to decline, and the operating price of photovoltaic power generation has dropped from 2-3 yuan/kWh to below 1 yuan/kWh (not including Taxes, management, maintenance, and grid sharing fees, etc.). It is expected that before 2020, photovoltaic power generation is expected to have the same competitive low-cost Internet access as coal power, and it will usher in an outbreak of growth.

The Municipal Economic and Information Bureau believes that the country has accelerated the pace of application of domestic photovoltaic power generation and has issued a series of policies and measures to support the development of the photovoltaic industry, which will provide good opportunities for the city to develop the photovoltaic industry. And compared with other developed areas of the photovoltaic industry, "Dongguan's photovoltaic industry has no historical burden and is more adaptable to innovation and development under the new circumstances."

Photovoltaic Power Generation Application Call for Policy Support

However, the "Report" also pointed out that the city's photovoltaic power plant projects are all self-initiated and connected to the power grid in the form of "connected to the grid without access to the Internet." “In terms of the entire industry, the biggest problem of photovoltaic power generation is still on the Internet, and there is a gap between traditional power prices,” said a person in charge of a photovoltaic power generation company that Matsuyama Lake is unwilling to name.

At the same time, the Municipal Bureau of Economics and Communications proposed that photovoltaic power generation at rest time (weekends or holidays) cannot be consumed by business units themselves for enterprises that use electricity during the daytime. This will affect the power station project if the energy cannot be recovered. The investment income also causes a waste of power resources.

In addition, since Dongguan has not yet introduced a special supporting policy for photovoltaic power generation applications, project declarations are mainly concentrated in enterprises within the industry, and it has not been able to effectively mobilize ordinary power companies and units to participate in the construction of photovoltaic power plants. The demonstration effect is not yet obvious.

Dongguan photovoltaic application "most"

Xinyi Industrial Park has the largest installed capacity
At present, the largest installed capacity of photovoltaic power generation in Dongguan is the solar roof power station project of Xinyi Industrial Park in Humen, with an installed capacity of 20MW and a total investment of 220 million yuan. It is expected that the annual power generation will be 21 million kWh after grid connection.

Of the 15 photovoltaic power generation projects in the city, 2 have been connected to the grid for power generation, and the cumulative power generation is about 2 million kWh. Among them, the project with the longest grid-connected operating time was the solar photovoltaic building integration project of Vanke's residential industrialization base. The cumulative grid-connected operation lasted 26 months and accumulated power generation reached 940,000 kWh.

Songshan Lake Photovoltaic Power Project is the Closest

From the distribution point of view, Dongguan has built and is currently constructing photovoltaic power generation application projects, mainly in Humen, Machong, and Songshan Lake. Nancheng, Shiqian, and Dongcheng also have a small number of distributions.

It is worth noting that Humen has 2 photovoltaic power station projects with a total installed capacity of 20MW; Mayong has 2 photovoltaic power station projects with a total installed capacity of 15.81MW; Songshanhu has 5 photovoltaic power station projects with a total installed capacity of 8.4MW; Nancheng has a photovoltaic power station project. 4, with a total installed capacity of 3.26MW; Shiqi has a photovoltaic power station project with a total installed capacity of 2.3MW.

The "Report" believes that with the application of large-scale photovoltaic enterprises to establish thin-film photovoltaic bases, and the application of distributed photovoltaic power generation application demonstration zones in the Mayong and Songshan Lakes, Qishi, Songshan Lake and Mayong will gradually become the city's recent photovoltaic power stations. The main area of ​​construction.

The country supports the most photovoltaic projects

Photovoltaic projects in Dongguan are mostly national support projects. Among them, the "Golden Sun" project is 43.14MW, and the photovoltaic building project is 2.92MW. Other companies self-built projects 0.17MW, government self-built projects 0.1MW.

The sources of funding for existing photovoltaic power plant projects are mainly from the state's Golden Sun project and photovoltaic construction project investment. National funds account for about 50% of the total project investment. The remaining investment funds are self-financing by the company and there is no separate loan for the project.

The highest proportion of the use of crystalline silicon components
According to the "Report," the existing PV power plant project investment recovery period is 5 to 13 years. The length of the investment recovery period mainly depends on the difference in the cost of the procurement period. In particular, the module price has fallen by more than 50% in 2011. The types of components used in existing projects are mainly crystalline silicon, accounting for 98%, and the local component usage rate is approximately 50%.

According to the data collected in the “reports”, the average power generation per kilowatt per day of the crystalline silicon module is 2.824 degrees, and the average daily power generation per kilowatt of the thin film module is 2.766 degrees. The crystalline silicon module is 0.06 degrees higher than the average daily power generation per kilowatt of the thin film module.

Photovoltaic power generation applications in Dongguan need to "push"

Electricity is the source of power for manufacturing. As a “world factory” that is known throughout the world, Dongguan needs a lot of electricity every year to support the development of the manufacturing industry.

According to relevant statistical data, the total electricity consumption in 2012 was 60.428 billion kWh, of which industrial electricity consumption was 45.229 billion kWh, an increase of 1.5% year-on-year, accounting for 14.9% of the province’s industrial electricity consumption, and electricity consumption per unit of GDP was 0.12 kWh. / Yuan, the industrial power consumption per unit of GDP 0.09 kWh / yuan ranked first in the province. According to the energy saving target issued by the province, the energy consumption per unit of GDP during the “12th Five-Year Plan” period in our city should be reduced by 19.5%, with an average annual decrease of 4.25%.

According to Dongguan's preliminary plan to promote photovoltaic power generation within five years, by 2017, the annual photovoltaic generation capacity will reach 4.0123 billion kilowatt-hours, accounting for 6% of the city's electricity consumption, which will enable the industrial power consumption per unit of GDP to drop from 0.090 kWh/yuan. To 0.068 kWh/yuan, the total electricity consumption per unit of GDP will fall from 0.121 kWh/yuan to 0.095 kWh/yuan.

If 3.7 GW of photovoltaic power generation projects are installed in the city, the price of photovoltaic products will decline by 5.7% every year, and a total of 24.952 billion yuan of product consumption will be driven within five years. Among them, the consumption of photovoltaic modules consumes 12.476 billion yuan, driving 1.5GW of production capacity.

Obviously, photovoltaic power generation has important economic and social benefits regardless of whether it meets the demand for electricity in Dongguan or whether it is energy-saving and consumption-reducing. According to the "Report," compared with the 0.4 to 0.7 yuan / kWh industrial electricity price in the Midwest, the electricity prices in various industries in the city are generally higher. It can be seen that the higher sales price means that photovoltaic power generation can use the electricity bill settlement method in Dongguan to recover investment faster. The economic benefits of building photovoltaic power stations are obvious.

The market has determined the application of photovoltaic power generation in Dongguan in both time and location. If we can get special support for photovoltaic power generation applications, the prospects will be even broader.
