Is there any reason why solar and wind farms cannot share the same piece of land? The number of solar arrays that would have to be omitted to make way for the turbines should be relatively few. The advantages are:
- Dual use of the land, (more power per square metre) and you could still graze animals.
- Shared use of much of the infrastructure such as transformers, switchgear and cables.
- Somewhat more even supply, more chance that the site would be producing something 24/7.
- Possibly output would be less weather dependent. I can't say for sure, but sunny days tend to be calm (Summer high pressure weather systems) and cloudy days are windy (Winter weather). This is a generalisation with exceptions and caveats.
There would be downsides, higher capital investment and sunny sites are not necessarily windy and vice versa. However they both are often found on less productive agricultural land, so in that respect vie for similar sites. But on the whole are there any technical disadvantages?
