Is there a policy on solar photovoltaic panels in China
The government subsidies for solar power energy projects have been considered "unsustainable" as the costs of subsidizing a rapidly growing industry are massive and some of China's struggles dealing with the costs have become visible. The renewable energy fund, which is paid by consumers, has a 100 billion yuan deficit while tariff payments have occasionally been paid late. Government subsidies for solar power have also been attributed to over construction, as many.
