Why do Chinese residents install and use household distributed photovoltaic (PV) systems?

Given the importance of promoting renewable energy, the Chinese government has enacted policies to encourage residents to install and use household distributed photovoltaic (PV) systems. However, only a few studies investigated factors influencing residents’ use intention for household PV systems.

How big is solar PV in China?

Solar PV of China accounted for about one third (174GW) of the global total installed capacity in 2018 and contributed to 3.5% of national total power generation in 2020 .

How many photovoltaic projects are there in China?

By the end of 2019, the cumulative installed capacity of household photovoltaic projects exceeded 10 GW, reaching 10.1 GW. In 2019, the total number of installed households in China exceeded 1 million, reaching 1.085 million ( Fig. 1 .1).

What is the future development trend of solar PV in China?

For the pathway modelled in this study, in which the technology improvement rate of HSPV during the past five years was considered, the total installed capacity would increase from 253 GW in 2020 to 1998 GW and 4548 GW in 2030 and 2050, respectively.

Why is photovoltaic power important in China?

In recent years, China's distributed photovoltaic power generated by households has developed rapidly, the NEA said, adding that this has played a vital role in ensuring the safe and reliable supply of electricity, promoting the green transformation of energy as well as driving the growth of farmers' incomes.

How does solar PV affect household adoption?

Qureshi et al. claim that a high level of generation enables households to switch more appliances to using solar PV, consequently increasing the likelihood of adoption. Panos and Margelous suggest that a household's ability to efficiently use energy generated from solar PV also plays a role in adoption.
