Overcapacity looming
After the central government asked local governments to save energy, reduce carbon emissions and develop high-tech industries, the local governments have been eager to develop the solar industry in their regions in the past few years. The photovoltaic industry happens to meet all those requirements.
More than 300 Chinese cities are making efforts to develop the solar photovoltaic industry, mostly driven by short-term interest, leading to the issue of overcapacity in the sector, said an official from the NEA who declined to be named.
Overcapacity in the polysilicon sector - a key material in the production of solar panels - led to 80 percent of the plants shutting down this year.
"There are more than 2,000 companies in the country's photovoltaic industry, half of which are focusing on producing solar products," according to Shi Lishan, deputy director of the New Energy and Renewable Energy Department with the NEA.
China controls nearly 70 percent of the world's solar panel production capacity and exports almost 90 percent of its output to Europe and the US. In comparison, Chinese companies only account for about 8 to 10 percent of the global solar products value chain.
Over the past eight years, the price of solar products has significantly dropped due to the development of solar technology in China. The cost of solar modules has been lowered to $1 per watt. The solar cells conversion rate has continued to increase, rising from 14 percent to 19 percent.
The investment return of downstream businesses - solar farms - is around 8 percent now, which is relatively good, industry players said.
Challenges ahead
Meanwhile, the challenges the wind power industry now faces could be the next hurdle for solar power development.
Roughly 25 percent of China's wind power isn't connected to the power grid due to limitations in the grids' capacity to transmit power from the distant regions where the power is generated to the power consuming areas. Also, local grids lack the ability to absorb wind-generated power, which can be quite unstable.
The less populated western part of China - which has more sunshine hours per year than other regions in the country - is the major destination for large-scale solar power projects.
In terms of installed capacity, China's top 10 solar power producers are: Qinghai, Ningxia, Gansu, Shandong, Jiangsu, Hebei and Shaanxi provinces and the Inner Mongolia, the Xinjiang Uygur and the Tibet autonomous regions. Those provinces and regions account for almost 90 percent of the country's output. Seven of those provinces and regions are in western China.
Located in Northwest China's Qinghai province, Golmud has been labeled the Photovoltaic Capital of China due to a series of large projects. One example is a 200 mW project by CPI Huanghe Hydropower Development Corp.
The province vowed to approve 1 gW of solar farms this year - one-third of the country's newly added capacity, an aggressive target that has raised concerns.
Solar power rationing has happened twice over the past year in Golmud, partly because the local grid was unable to absorb the solar-generated power, causing millions of yuan in losses for local solar farm developers.
In 2011, China's connected solar capacity was 2.12 gW, or nearly 70 percent of the installed capacity, according to the China Electricity Council.
"The grid infrastructure in the western regions is not adequate to support solar connections," said Zhang Qian, a senior official at Canadian Solar. "More transmission lines need to be built."
Electricity needs to be transmitted to the grid before being distributed, which requires companies to convert solar power into high-voltage electricity.
"This process adds more costs," said Lian of Solarbuzz.
Therefore, electrical grid companies are reluctant to connect solar power into their systems.
The central government started subsidizing grid companies in 2012 in an effort to encourage them to bring more renewable energy into the country's power system.
However, the subsidies only cover part of the costs, according to Jiang Liping, deputy director of the Energy Research Institute, which is affiliated with State Grid.
More costs may occur as local governments start to tax the land for the projects, and getting the limited approvals is becoming expensive.
Most developers are State-owned power companies, such as China Huaneng Group, China Huadian Corp, Datang International Power Generation Co, and China Power Investment Corp.
A few private developers such as Hanergy and Astronergy are also involved in the business.
For now, the issues do not seem urgent as installed capacity is still limited, but they might hamper the development of the solar sector in the future.
Solar power integration could become a more serious issue that it was for the wind power industry when applications scale up because solar power requires more flexible technology, according to Bai Jianhua, chief economist of the Energy Research Institute.
Another 35 gW of solar projects are in the pipeline, according to Solarbuzz's estimate.
But China wants solar power to be a real alternative to traditional power plants by 2015, which means that the price of solar power can be comparable to traditional power sources.
And despite a recent adjustment in renewable energy policies, the country is still committed to develop clean energy, with unprecedented investment flowing into the sector.
In the second quarter of the year, the country led clean energy investment with $18.3 billion, a 92 percent increase compared to the first quarter of last year. The largest Chinese PV project financed recently was the Shanlu & Shengyu Bayannur Wuyuan plant, with $316 million, Chinese media reported.
