Hello /diy/,

I have a basic understanding of electricity but need some help. I am purchasing some solar cells that each have 2.8 watt, .5 volt output. What could I do to change that to 5 volt 1 amp? This is a project for making a solar powered USB charger.

5 volts at one amp is 5 watts
2.8 watts is less than 5 watts

Buy more cells.
Arrange series/parallel until you achieve 5 watts output.
???
buy something useful.

He'd have 5.6 amps. Each cell is 5.6 amps. Putting them in series adds up the voltage, not the current.
