This has been researched and found impractical. First you have power conversions solar > electric > microwave > electric. Then the microwave transmission receiver has to grow at the square of the distance. Receivers need to be huge on the order of kilometers. Also to be stationary to the ground the satellites need to be in geo orbit making the distance huge.
