I know, old gravel pits, but I can’t help wondering what would be the effect of the lack of sunlight in the long run? You can’t compare them with deep underground reservoirs that has no sunlight either. They also have no fresh oxygen supply nor other external influences.
It can reduce evaporation and reduce algae growth afaik. It doesn’t have to be bad.
Though … swimming vertical solar panels are also a thing.
Quite a bit of sun radiation gets through the panels i believe, so it wont be completely dark below. Im sure the types of flora to be found will change a lot tho.
Yeah, would a panel farm at a heigh sheep can graze beneath not be lower impact? Stagnant water isn’t much of an ecological bonus, though the panels would be more efficient if the water cools them effectively

That’s not what I said. I know about advantages of water cooling them, but i’m just wondering if this not might come with an un-expected ‘pricetag’ at some point in the future.
How does it compare to an alternative as mounting them over a parking lot (or even some roads)? Yes, the panels would be less efficient, but you don’t need to transport the electricity far and there would be savings on airco usage of the vehicles. Would it also be beneficial for the temp in the area not having the sun scorching the road but the panels which are air cooled at the top and bottom ?
France has already mandated PV placement in parking lots. I think you may be confusing “instead of” with “as well as”
This is an industrial site with no aquatic life in the pit to save. Yes rehabilitation would be great, but at least positive environmental use is being made of an otherwise dead site

Nope, never said instead either ;)
While it’s an abandoned industrial site I’d like to point out to the Kreidsee, in Hemmoor in Germany which also is an abandoned quarry (1862 - 1976) which is filled with water. Today is’t used for deep diving and deco training and has it filled itself with all sorts of underwater life too (yes, i’ve seen it first hand).
So don’t get me wrong, I’m not against it, I’m just wondering about the effects this solution could/might have. I’d expect the higher humidity levels directly above the pond will have (negative) effect on the live expectancy of the panels too. So i’m just questioning if it’s a good idea in the long run, but I guess time will tell. (Would been nice if they left a pit uncovered so we have something to compare it with but I doubt that)
