This energy would then be transmitted to one or more stations on Earth.

And how do you suppose to do that?

Beam the power from space like they do in Mirai Shounen Conan? Or space shuttles with batteries? Or a giant cable that somehow doesn't break?

It's not possible.

RD1 generates power 99% of the year and collects solar radiation by autonomously redirecting its reflectors toward a concentrator to focus sunlight throughout each day. RD2 uses flat panels, with solar cells facing away from Earth and microwave emitters facing toward the Earth. RD2 generates power 60% of the year due to its limited capability to reposition itself or redirect solar radiation toward its solar cells.
