A solar panel can run this. Or, to be more specific, a small (3" x 3") solar panel could charge a 3v battery which could power this device. I have solar-powered holiday lights which operate on 3v, this application would be simply replacing the lights with this chip. I've actually replaced the charging circuit with a TI MSP-430[1], and powered it directly with solar power. [1]a microcontroller similar to Arduino which operates on 3.3v and was intended to cost $4.30 for the entire development kit. http://www.ti.com/msp430 http://www.ti.com/msp430
