Electric charges and Asteroids

I was thinking that if many asteroids are loose collections of dust held together by the weak gravity they generate, then there couldn't be much of an electric charge on them or the dust particles would be repelled from like charges.

Could it be that if there were massive dust balls with large electric changes on them then they'd be hollow? Or fluffy sort of the way a kids hair stands up when touching a van de graff generator?

Wouldn't the solar winds almost certainly create large electric charges on anything in space?
