A new Solar option for battery powered doorbell

I have a doorbell 2. House is not wired for a doorbell, so am using battery option. The doorbell is under a 6 ft+ portico. I currently have 2 battery packs I alternate, and am swapping about every 2 weeks. A solar option with wire that I can run to remote solar device I can place where it would get sun would be nice. Having to swap batteries so often gets a bit old. (Of course, I guess I could get an electrician to wire house for the doorbell if you think that’s the better option.)
