Solar power rain around the world

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.

How does weather affect solar power?

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. On a cloudy day, output can drop by 75%, while their efficiency also decreases at high temperatures.

Could solar farms boost rainfall in the Sahara Desert?

In a 2020 study, researchers found that implausibly large solar farms, taking up more than 1 million square kilometers in the Sahara desert, could boost local rainfall and cause vegetation to flourish. But the bounty would come with a cost, the researchers found: By altering wind patterns, the solar farms would push tropical rain bands north.

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.

Could solar panels increase rainfall in arid regions?

Rainmaker: installing solar panels in some arid regions could increase rainfall. (Courtesy: Shutterstock/motorolka) Placing large-scale solar farms on the Arabian Red Sea coastal plain could dramatically increase rainfall in this arid part of the world, a new modelling study claims.

Can solar power change weather patterns?

Branch works in an emerging field that studies how renewable energy, a key response to climate change, can in turn alter regional weather patterns. In a 2020 study, researchers found that implausibly large solar farms, taking up more than 1 million square kilometers in the Sahara desert, could boost local rainfall and cause vegetation to flourish.
