If you want 24/7 energy in space you're saying "My satellite will be in sunlight 24/7". And there is a also a downside to that.

1) Space is not cold. Space is not hot either. Temperature is a property that matter has, and space is literally the absence of matter. Empty space does not have temperature at all, just like it doesn't have weight.

2) Heat is passed by conduction, convection and radiation. Across space, only radiation applies. Light carries heat across empty space.

3) If you're in sunlight 24/7, the sun is sending heat to you via radiation. 24/7. Where does that heat go? Unless you radiate it, nowhere. It just builds up, along with the inevitable heat from running chips.

How hot? In The surface temperatures on the Moon - in sunlight, same distance from the sun and in vacuum - get up to 250F / 120C during the day there.
