Solar calculators can run off ambient lighting and BLE is very efficient so you’ll get months of runtime from a few hours in the sun, and most people leave their house (or refrain from using the PC in the daytime) at least that much.
I wonder if the “battery lasts 10 years” claim refers to a single charge or its chemical lifetime, either is possible with BLE and the form factor.
Not really. I have a logitech mini pop keys bluetooth keyboard, and it has a year-long battery life with 2 AAA’s. The Pro ones with key backlights have week-long battery life.
So you need two of them, one in use, and one charging in the garden. Unless you enjoy using your computer in the sun for some reason.

This is easily doable.
