JAXA's pie in the sky SSPS project avoids the problem of variability of supply. Emplaced at a Lagrange point, one could imagine a potential 24/7 source of energy. Also, one of the proposed ways to transmit the energy back to earth is via lasers. Could be fun if there are issues with the targeting subsystems :)
