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.

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 PV compete with electricity from the grid?

The results showed that rooftop solar PV cannot compete with electricity from the grid due to the current residential electricity prices. Even assuming aggressive reductions in the investment cost of solar technology, photovoltaic solar rooftop installations were not encouraging .

Can rooftop photovoltaic systems generate energy in cities?

Urban environments can be considered as high-potential electricity producers using rooftop-mounted photovoltaic systems. There is an increasing number of studies investigated the rooftop photovoltaic potential to generate energy i cities.

Does a high-resolution global assessment of rooftop solar photovoltaics potential exist?

Yet, only limited information is available on its global potential and associated costs at a high spatiotemporal resolution. Here, we present a high-resolution global assessment of rooftop solar photovoltaics potential using big data, machine learning and geospatial analysis.

Is residential solar rooftop potential cost-efficient?

Residential solar rooftop potential was presented in Riyadh (Saudi Arabia), to assess the cost-efficiency, by combining two different methodological approaches, namely standard Leverage cost of electricity approach, and nightlight intensity methodology.
