Is powering an ATMega328 & ESP8266 via indoor lights possible?

Experts,

Some vendors sell solar panels that can be powered by indoor lighting, and I am looking for a power solution that will not need to be revisited (battery change, charging, etc.). The only draw will be from the regulator/solar shield and an ESP8266 or maybe a nRF24L01... (obviously the panel(s) and Lion battery(ies) are there, but I wasn't considering them a load...)

So has anyone been able to keep an ATMega328P or nano running indefinitely under these conditions?
