6 FAQs about [Rooftop solar photovoltaic power generation investment promotion]

Does rooftop PV generate economic benefits?

In this study, we calculated two kinds of economic benefits. First, we calculated the economic benefits generated by the annual electricity generation of rooftop PV. Since the annual electricity generation of rooftop PV was lower than the resident's electricity consumption, we assumed the second situation.

Why is rooftop PV an unattractive investment?

The high cost of PV components and the continued reduction of government subsidies would lead to the rooftop PV being an unattractive investment. Therefore, these factors need to be considered when developing rooftop PV.

Is rooftop PV a trend for building energy conservation?

Mainzer et al. (2017) employed open earth data and image recognition techniques to obtain the roof useable area at the city level of Freiburg and identified the rooftop PV potential of 524 GWh/a. As described above, previous research has shown that the use of rooftop PVs is a trend to realize building energy conservation.

Is rooftop PV a good investment in Nanjing?

Moreover, according to the results of the economic benefits assessment of rooftop PV, the installation of rooftop PV in old communities in Nanjing cannot generate high returns, especially when the cost of distributed PV systems is high ( Martinopoulos, 2020 ).

Can rooftop PV be used in large-scale energy-saving renovation in cities?

These conclusions provide evaluation method references for the application of rooftop PV in large-scale energy-saving renovation in cities, and also provide theoretical guidance for the development of rooftop PV plans by energy sectors in China. Peng Wang: Conceptualization, Methodology, Formal analysis.

Is rooftop PV a viable alternative to a pure PV system?

PV is extensively used, Liu et al. (2022a) proposed that an integrated system of rooftop PV and electric vehicles has a higher PV utilization rate than a pure PV system, promoting the integration of PV with multiple industries.
