How much energy does a rooftop PV system generate in Xiamen?

The results show that in Xiamen City (Fig. 7), a 1 kW rooftop PV system generates 3,873 kWh annually. Based on the PVWatts model, a 4 kW PV system covers approximately 28 m², and the usable rooftop area in Xiamen is estimated to accommodate about 1,915,279 units, generating approximately 7,427 GWh annually.

Does Xiamen have a PV-GR system?

Using Xiamen City as a case study, research shows that Xiamen has about 54 km² of rooftops suitable for PV-GR. Annually, PV-GR can produce about 5.931×10 3 tons of biomass and generate 7,427 GWh of electricity, meeting about 22.13 % of Xiamen's annual electricity demand.

How much carbon does Xiamen's PV-GR reduce?

The annual carbon reduction from Xiamen's PV-GR is estimated at about 5.131×10 6 t CO 2-eq, offsetting around 29.28 % of the city's annual carbon emissions. Over a 30-year lifecycle, PV-GR's carbon emissions and reduction benefits amount to 2.274×10 7 t CO 2-eq and 1.539×10 8 t CO 2-eq, respectively.

Are PV facilities on cropland a problem in China?

However, the rapid expansion of PV facilities on cropland in China has become a global concern. The location of PV facilities to croplands with high agricultural productivity has exacerbated the conflict between renewable energy production, food production and ecological conservation in China .

Is China a hot spot for solar energy development?

Currently, China has become the global hot spot for PV solar energy development. Notably, China's installed PV capacity attained a leading position worldwide for the first time in 2015. Since then, China has maintained its dominance in the PV industry.

What are the future directions of PV development in China?

4.5. Future directions and limitations The rate of PV development in China is rapid, with government initiatives targeting desert, arid, and barrens for the establishment of large-scale PV facilities. The goal is to achieve an installed capacity of 552.05 GW by 2030.
