Photovoltaic power generation last hit "strengthener"

Recently, China Steel Group's roof photovoltaic power generation project in Changxing County, Huzhou, Zhejiang Province was formally connected to the grid for power generation and operation, giving a boost to the photovoltaic industry in the “winter”.

This year, China's exports of photovoltaic products have been severely hampered, and the search for the domestic market has become an important path for photovoltaic companies to get out of trouble. Zhejiang Changxing adheres to the national policy of low-carbon energy, taking the new energy industry as an important target for cultivation, and has embarked on a development path of positive interaction between ecology and economy.

Planning and clarifying the advantages of industrial clusters Since clearly acquiring the first batch of 13 “Golden Sun” PV demonstration zones in 2010, Changxing has firmly grasped the regional advantages of industrial clusters and successively attracted Zhengtai New Energy, Hanergy PV, and Guangpu Solar Energy. A large number of industry giants settled in Changxing, with a total investment of over 10 billion yuan.

Changxing County takes advantage of the situation and seizes the favorable opportunity for the rise of new energy sources such as photovoltaics to seize the commanding heights of future competition. In December 2011, Changxing County promulgated the “Opinions on Accelerating the Development of New Energy Industry (2011-2015)”, and clarified the key points for the future development of Changxing PV industry. According to the “Opinions”, by 2015, it is expected that the photovoltaic output value will reach 20 billion yuan, and a photovoltaic integrated industrial park based on development zones and a relatively complete industrial cluster with an industrial chain will be initially formed.

Continuing to strengthen the grid-connected foundation As a national gold sun demonstration project in 2010, the total investment of the 10MWp rooftop solar power generation project in Changxing Economic and Technological Development Zone is 200 million yuan. It covers an area of ​​approximately 154,000 square meters and is distributed on the roofs of 20 enterprises in the development zone. In the past two years, thanks to the support of local governments and the power supply sector, a large number of projects such as Changxing Pharmaceutical, CHF Electronics, and Bolumeng have been installed one after another.

According to the plan, the 10MWp rooftop solar power project will be designed to use distributed power generation and grid connection. The average annual power generation capacity will reach 10 million degrees, and it is estimated that 1390 tons of standard coal can be saved annually.

During the installation and commissioning of the project, the Changxing County Power Supply Bureau established the photovoltaic grid-connected research and development team to take the initiative to provide on-site service and guide the preparation of the project to the grid. At the same time, the Bureau also cooperated with universities to carry out the "coordinated operation technology research of high-density multi-access point rooftop photovoltaic system and distribution network" to make technical preparations for grid-connected work.

Policy Breakthrough Title Photovoltaic grid-connected and orderly promotion In response to the State Grid Corporation's policy of supporting photovoltaic power generation projects, the Changxing County Power Supply Bureau established a photovoltaic power generation project service team to strengthen special training for employees and launch the “full-range guidance system” and “time-limited solution system”. For the photovoltaic companies to open up a green channel, full guidance, so that project construction and grid access more standardized and efficient, to minimize the processing cycle. On November 30 this year, the 10MW photovoltaic grid-connected power generation project in Changxing Development Zone was applied for on-grid connection. The Changxing County Power Supply Bureau sent a person to supervise and completed the data reporting of 20 grid-connected sites in just one hour. The "Distributed Photovoltaic Power Generation Grid-connected Service Manual" is provided to users, which facilitates the user to follow the map, accelerates the implementation process, and fully understands the interconnection process and technical specifications.

It is reported that Changxing currently has 22 rooftop solar photovoltaic power generation projects under construction, with an installed capacity of 14 megawatts. It is expected that all of them will be connected to the grid early next year. According to the plan, by 2015, the total installed capacity of photovoltaic power generation in Changxing County will reach 150 MW.
