Can we power SCUTTLE robot 100% using $22 worth of solar panels?

SCUTTLE uses 7 watts to perform driving, computation, and communication simultaneously. (from a previous test) If we hook up a cheap solar panel from can we provide enough power for the whole robot? This panel is rated for 10watts, but in today’s test I could get just 5W. That means with two units, I can fully power our mobile robot and even charge the batteries some for later! I’m sure this panel is easy to get in USA through amazon as well. Who wants to help build a fully SOLAR SCUTTLE? SCUTTLE Project:
