FAQs 6

Do photovoltaic solar farms affect global solar power production?

This may further lead to disturbance in the global climate and hence the global solar power production. We aim to quantify the impacts of a large-scale deployment of photovoltaic solar farms in the Sahara on global solar power generation as a pilot case study, and investigate the underlying forcing mechanisms.

Do large-scale solar farms increase rain and vegetation cover?

Li, Y. et al. Climate model shows large-scale wind and solar farms in the Sahara increase rain and vegetation. Science 361, 1019–1022 (2018). Lu, Z. et al. Impacts of large-scale Sahara solar farms on global climate and vegetation cover. Geophys. Res. Lett. 48, e2020GL090789 (2021).

Do solar panels affect climate?

Here we find that solar panel electricity generation will redistribute the energy from the sun, thus affecting regional and global climates. Without the solar panels, solar radiation reaching the surface is partitioned into absorption and reflection.

How do PV panels affect rainfall?

The raindrops intercepted by PV panels during rainfall will concentrate along the lower edges of PV panels and fall onto ground surface, causing heterogeneous spatial distribution of rainfall (Barron-Gafford et al., 2019, Jahanfar et al., 2019). Some researches indicated that runoff in slopes or hillslopes can be increased by PV panels.

Do climate-altering solar farms affect solar power production?

In our new research we have looked at the effect such climate-altering solar farms might have on solar power production elsewhere in the world. We know that solar power is affected by weather conditions and output varies through the days and seasons. Clouds, rain, snow and fog can all block sunlight from reaching solar panels.

How would a solar farm affect solar power generation around the world?

In our recent study, we used a computer program to model the Earth system and simulate how hypothetical enormous solar farms covering 20% of the Sahara would affect solar power generation around the world. A photovoltaic (PV) solar panel is dark-coloured and so absorbs much more heat than reflective desert sand.
