Dongwen Liu, CEO of Chongho Bridge, noted that rooftop solar projects could boost the annual cash income of rural populations by 10%-20%. The collaboration with Chongho Bridge is anticipated to yield significant environmental and social benefits for rural households, businesses and their wider communities through rooftop solar power generation.

These installations, accounting for 58% of new PV installations in 2022, are favored due to lower investment requirements, reduced construction costs and greater flexibility.
Rooftop photovoltaic (RPV) systems offer a viable solution for urban energy transition by utilizing idle rooftop space and meeting decentralized energy needs. However, due to limited information on building function attributes, detailed assessments of RPV potential at the city scale are still complicated.
It will require an extensive expansion not only in solar PV but in other types of renewable energy, such as wind and hydropower, which in all are projected to account for up to 80% of power generation by 2060.
