China's PV solar market will develop at an annual growth rate of about 20.2 percent over the next few years, Wang predicted. Meanwhile, the share of distributed solar power generation among the overall solar market will grow from 30.3 percent in 2011 to 45.24 percent in 2015.

"The current overcapacity problem in the global PV solar market is temporary, lasting just a few years," he said. "The demand in the market will grow by a large extent after about five years."

The Chinese government is not the only one supporting the PV industry across the world.

The US government provides tax breaks for homes or businesses supporting the domestic solar PV market, according to a report from GlobalData, an international business intelligence organization that focuses on energy, resources and healthcare sectors.

It said between 2009 and 2011 the US Treasury provided 3,731 grants for solar power projects, amounting to a total of $1.56 billion, for the installation of solar power projects equivalent to 1,290.64 megawatts.

The US government has also increased spending on PV in federal buildings and the defense sector, investing in PV equipment for military power supplies and the government sector, the report said.

Currently, the solar PV module market in North America is dominated by the US, which accounted for more than 85.3 percent of regional additions in 2011.

Chinese company Trina Solar Ltd is working on expanding the Canadian market by investing in the area and cooperating with local partners.

Many foreign experts believe Chinese companies will survive the crisis.

"It's easier for Chinese companies to beat the competition," said Buttgereit. "In the EU it is impossible to get loans from banks because of the bad economy there."

He said the debt crisis and weak economy is a much tougher issue in Europe than PV industry problems and some companies will not survive - a natural outcome of market economics.

He believes that China will become the biggest PV solar player in one or two years.

In the Chinese government's 12th Five-Year Plan (2011-15) on the energy industry, it states the country will reach a total solar power installation capacity of more than 21 million kilowatts by the end of the plan period.

Opportunities

As PV solar companies struggle to survive, some thin-film solar power producers have been making moves to speed up their development.

Thin-film solar cells, which have a 20 percent market share globally, are a less efficient photovoltaic technology than the widely used silicon panels which are the products that aroused the US and European probes into anti-dumping and anti-subsidies involving Chinese products.

First Solar Inc, a US-listed clean energy developer that specializes in thin-film technology, said in early December that it will cooperate with Chinese company Zhenfa New Energy Science and Technology Co to supply two megawatt thin-film solar modules for Zhenfa's solar projects.

The solar projects owned by Zhenfa have been approved and are located in Xinjiang Uygur autonomous region.

Just a week before the US company's announcement, Chinese private power generator Hanergy Holding Group Ltd announced it had become the world's largest maker of thin-film solar modules, replacing First Solar, with an annual capacity of up to 3 gigawatts.

Hanergy has invested around 27 billion yuan ($4.3 billion) in its thin-film research and development and production bases so far, according to the company.

Although both the domestic and foreign companies are eyeing China's thin-film solar market, experts say its future is uncertain.

"The market share of thin-film solar cells has been falling over the past few years globally because the price of polysilicon has dropped dramatically," said Meng from the China Renewable Energy Society. "Compared with the polysilicon-made PV solar panels, the thin-film solar cell's energy efficiency and lifetime both have much room to improve."
