Why is China doubling its rooftop solar capacity?

The country's rapid development of rooftop solar capacity is also driven by government incentives. Newly added annual installed capacity for solar stations has been around 30 GW on average over the past few years, China New Energy Investment and Financing Alliance said.

How many rooftop solar photovoltaic projects are there in China?

It has entered a rapid development stage (Li and Huang, 2020, Anon, 2022a). There are 676 rooftop solar photovoltaic (RTSPV) pilot projects in 31 provinces in China in 2021 (Anon, 2021a). Rooftop solar photovoltaics use building roof resources to design distributed photovoltaic power stations (Tripathy et al., 2016).

Will rooftop solar PV installations in China surge in the next 3 years?

Rooftop solar PV installations in China may surge in the next three years as the country goes through a green energy transition and plans to make renewable energy a key cornerstone in the country's path to a greener economy, a recent research report said.

Will China's rooftop solar market grow in 2021?

Rooftop installations in China increased to 27.3 gigawatts in 2021 from 19.4 GW in 2017, and the growth should keep rising for the rooftop solar market, a Rystad Energy analysis piece said. Before 2017, rooftop solar was almost non-existent, with only 4 GW of installed capacity in 2016.

How much electricity can China generate from rooftops?

The result shows that the rooftop generation potential in China is 3.27×109MWh annually, which is close to half of the total electricity generation of China mainland in 2020, and will contribute to 2.41×109tons of CO2emission reduction per year.

How has China impacted global solar capacity?

The increased adoption of rooftop installations in China has also driven the world's total global rooftop solar capacity, which has jumped 64 percent in five years, rising from 36 GW in 2017 to 59 GW in 2021, representing 30 percent of total global solar capacity, it said.
