Anyone have a solar setup for a pond/pool filter?

We currently are only using a small plastic kiddie pool for our 3 ducks. Not sure in the end when they are full grown how big of a pool/pond we will go.
So, keep in mind that currently I'm referring to a kiddie pool, any idea what size filter and pump I would need for a duck pool?
How about solar. Has anyone used solar to power pump and filter?

Thanks

I have the same question being invthe same situation.  I have six ducks and they make do with their kiddie pool and really appreciate it.  I hope to offer them more next spring and dig a small pond for them.  Solar is my only option to keep the water moving and filtered.  Will probably need something to skim out feathers too.   They found my ornamental pond/waterfall and quickly clogged the pump with feathers.  As I conduct my research I can post it here.  Please do the same.  This is my winter project.

You could look into airlift pumps. Quite simple to build and can’t get cluttered with feathers.

Air lift, will check into them, thank you for the tip!
