Economic analysis has been undertaken for PV systems designed for the apartment and villa buildings described in Section 4. The main approach used to assess the feasibility of rooftop PV systems in this study is the levelized cost of electricity (LCOE).
A novel systematic method for assessing the potential of urban rooftop PV is proposed. Residential areas contribute 50% of the total rooftop PV potential in Guangzhou, China. The rooftop PV potential in Guangzhou reaches 44.06–72.12 billion kWh per year. Rooftop PV reduces carbon emissions in the power sector in Guangzhou by 72.12–100%.
The economic evaluation of rooftop PV systems should be considered in a case by case scenario. The assessment cannot be generalized due to the factors like buildings energy load profile, available solar resource, roof utilization factor and PV system design mechanics.
For cities with rich solar energy resources (such as Mohe), rooftop PV systems can yield substantial benefits, even under high shading. However, in cities like Urumqi, despite having ample solar energy resources, the on-grid electricity prices are relatively low, leading to much lower investment returns and longer investment payback periods.
