FAQs about Are there any subsidies for photovoltaic panels connected to the grid

How does PV technology cost affect PV subsidies and PV capacity?

According to China's policy regulation, an important basis for reducing subsidy levels lies in the reduction of PV technology cost. Thus, PV technology cost affects PV subsidies and PV capacity simultaneously, and should therefore be controlled for in the regression analysis.

What is the Current PV subsidy policy?

The current PV subsidy policy—the zonal FIT policy—was enacted in August 2013 and went into effect in 2014 . It divides mainland China (except Tibet) into three different zones (Fig. 1).

How will China's solar subsidies affect the solar industry?

The reduction in subsidies could place additional strain on China's solar industry, which is already grappling with overcapacity and plummeting panel prices that threaten the viability of smaller manufacturers.

Does governmental subsidy support China PV companies?

Although governmental subsidy strongly supports the China PV companies, few of them have competitiveness in the global market. This dramatically conflictive phenomenon attracted many researchers' attentions in recent years.
