The value of China's total solar photovoltaic (PV) manufacturing output topped $31 billion in the first half of 2015, the industry ministry said on Wednesday, as the push for renewable energy continues in the world's largest solar PV producer. 

In the first half of 2014, the total output value surpassed 150 billion yuan ($23.44 billion). 

China, the world's top greenhouse gas emitter, has committed to halting the rise in CO2 within the next 15 years to help build a United Nations climate deal in late 2015.
