Rooftop solar photovoltaic power generation atlas

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.

What is rooftop solar PV?

Rooftop solar PV is a valuable addition to other renewable-energy sources, like open-field PV, as it utilizes existing infrastructure, reduces land consumption, and supplies electricity where it is needed. An accurate assessment of the rooftop solar PV potential is essential for efficient and sustainable resource use.

Do rooftop solar panels generate electricity?

The first detailed global assessment of the electricity generation potential of rooftop solar panels has revealed that the total global potential for electricity produced in this way exceeds all the energy used worldwide in 2018.

Can rooftop solar photovoltaic systems contribute to Europe's energy transition?

Rooftop solar photovoltaic (PV) systems can make a significant contribution to Europe's energy transition. Realising this potential raises challenges at policy and electricity system planning level. To address this, the building stock to quantify the available rooftop area for PV systems.

How do I use the Global Solar Atlas?

Welcome to the Global Solar Atlas. Start exploring solar potential by clicking on the map. Select sites, draw rectangles or polygons by clicking the respective map controls. Calculate energy production for selected sites. The Global Solar Atlas provides a summary of solar power potential and solar resources globally.

Do rooftop photovoltaics have a potential?

Due to the spatiotemporal variability in the solar radiation on roof surfaces, it is essential to determine the potentials of the rooftop photovoltaics and its variations in specific regions. In Germany, this potential was assessed in 5 km × 5 km zones, as well as at the federal-state and national levels.
