I am a retired N.A.S.A. Eng. almost all of our sat elites use solar cells. What kins of load u thinking about,u need to calculate the solar cells for a minimum of 100% over your load. That sounds like a lot and u need a battery system to store it. In space there is no clouds so u think u could use much less. In space the thing that most people don't think about is when the spacecraft is in the shadow of the earth,even if it is in a orbit of 23,000 miles it can still get in trouble during equinox. If u use an antenna that points at the earth if the sun is blocked it will loose sync. Another problem is to let the voltage drop until it affects the stability of the transmitter or receivers.

At present, impractical, due to problems getting power from satellite level to the ground. It has been proposed to use microwaves for this, but the waves would have to be sharply focused at a suitable collector to avoid one-over-r-squared losses, which would be prohibitive.
