Arduino Mega Powered by Solar

I am using an Arduino Mega 2560 in order to gather wind and GPS data and present it, but I want the board to be powered by solar panels. Anyone know what kind of panels I should be using and how much wattage I need from the solar panels?

Measure the current drawn by your mega and post it. Say where you live. Nasa publishes insolation values for the sun by location.

Use the solar panels to charge a good big 12v lead acid battery and drive the Mega from the battery. And, of course, the solar panels must be able to produce considerably more energy than the Mega requires.
