@LiberalEd - the pressure of the solar wind near Earth's orbit is usually about 6 ×10⁻⁹ newtons/square meter, where a newton is enough force to accelerate a gram at one meter/second². This is not much. The Lisa Pathfinder satellite was a test of concept satellite with micronewton thrusters and a mass floating inside it; it worked fine.

There's a lot of material on it in the references here:
