Solar Charger for Peephole.

Hello, I live in a townhouse rental where I can’t get hardwired/drilled doorbell so I’m currently using a peephole doorbell instead.

It’s great so far but the battery life is terrible. Extra battery doesn’t really help. I get sunlight where I live so it would be nice if you guys could make solar charger for the peephole as well where my doorbell camera can keep it running.
