Wouldn’t it be better to have some underground cistern and as water flows down it passes through a turbine? A roof solution will generate a tiny amount of electricity.
Congrats, you've invented the hydroelectric dam.
I pay about $30/month for local utility water. It's metered, but I rarely exceed the minimum billing amount.
If the generator cost $100 to buy and install, it would take nearly a century to pay back its install cost even in one of the rainiest locations in America.

Or at least put a remote trigger on it so you can get some splash damage on your target.
