Dams normaly have a specificly designed spillway as it could otherwise be VERY dangerus (the water removeing dirt at its base , possably leading to dam failure)
I doubt the solar panels were put on it tho
If water is just overflowing it entirely like a glass of water then shits so fucked that the solar panels just dont matter

What better way to prevent war then ensureing your primary enemy is fiscally , demographically and politically unable to fight?
Let alone militarily
