All four Cluster satellites will fly independently, controlled by radio contact with a ground station on earth, rather than talking among themselves about where they are.

ECONOMIST: Birds of a feather

Instead of trying to maintain a constant stream of communications with a subscriber, the satellites simply receive short messages and zap them down to one of their ground stations on earth.

FORBES: Iridium for truck trailers

Given the risks of aiming such a powerful beam of high-intensity radiation at an Earth ground station, as well as the cost of building billions of dollars in infrastructure to collect the energy in space, the efficiencies you can get from terrestrial solar power seem a safer bet--at least for now.
