Solar power generation assessment report

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.

Which parameters affect solar power generation?

Normalized total sensitivity of each parameter. The results show that the theoretical power generation is most sensitive to the changes in solar altitude, the tilt angle of the PV panel, and solar azimuth.

Are solar power generation and land suitability based on ERA5 data?

Firstly, the high spatial-temporal resolution and high-quality ERA5 data and related technical, geographic, and social factors were used to assess the theoretical power generation and land suitability of PV power generation.

How much power does a solar panel produce per unit area?

In other words, the peak power per unit area can be up to about 200 W/m 2 (standard state: solar radiation: 1 kW/m 2; the temperature of panel: 25 °C; solar spectrum: AM1.5). But in practice, not all PV modules can reach the highest level. Therefore, a conservative estimation is used in this study.
