Why is rooftop solar potential important?

The assessment of rooftop solar potential is vital for optimal photovoltaic (PV) system placement and renewable energy policy in dense urban areas. Complex shading from buildings and diverse rooftop obstacles have posed significant challenges to this evaluation.

Can rooftop solar power be used in high-density cities?

In sum, the approach developed in the current study appropriately estimate the potential of rooftop solar power generation, which can establish clean and low-carbon energy systems, including photovoltaic systems, for buildings in high-density cities.

Can rooftop solar power be produced in Shanghai?

Using this hybrid framework, we calculated the available rooftop area in Shanghai, excluding the Chongming Island, and produced a detailed map of PV potential. Results show that the estimated annual potential for rooftop solar radiation in Shanghai stands at 257,204 GWh, with a predicted annual PV electricity generation of 49,753 GWh.

How to simulate rooftop solar potential in Adelaide?

Zhao et al. used building models of several different types of blocks in Adelaide to simulate the solar radiation, which are mainly constructed by converting building parameters (building type, height, area, etc.) to 2.5D building models. Finally, random forest algorithm was utilized to simulate the rooftop solar potential of Adelaide .

Should city rooftop solar capacity be assessed?

The International Energy Agency (IEA) predicted a growth of the world's total renewable-based power capacity of 50 % between 2019 and 2024 . Thus, it’s vital to assess city rooftop solar capacity in order to develop relevant policies and plans for PV system design, which facilitates the realization of low-carbon cities. 1.2. Literature review

How much electricity can a rooftop solar system generate a year?

It then calculates that if every suitable roof was used, rooftop solar could generate 19,500 TWh of electricity per year, allowing for fossil fuel-based electricity to be replaced almost entirely, when coupled with load shifting and battery-electric storage.
