Power bricks today are really simple regulated DC Power Supplies. They just supply a fairly precise Voltage up to some amount of Current. I have a DC Supply that is adjustable from 5 to 30 volts up to 50 amps. It does not care what it is connected to, all I have to do is match the Voltage and ignore current because I have more than will be required by any device.
What I am driving at is all you have to do is match the Voltage and supply the maximum amount of current your gizmo uses. It can be done with solar and a few components about $4 worth. No the problem is how the heck you are going to be able to supply a dynamic power from a solar panel? One would think if you needed say 14 volts @ 3 amps all you need is a 50 watt panel. Wrong Dead wrong. A 50 wat panel only puts out 50 watts for a few minutes around noon. What do you do in the morning or afternoon when the panel can only generate 25% of its rated power.
How do you get around that? That is the problem you have to solve. Extremely easy to do, but expensive and impractical, you use a 250 watt panel for a 50 watt device. But even then you are limited to only bright sunny days for a few hours around noon. What do you do for the other 18 hours of the day?
