Solar energy is attractive, the sun’s energy is free and in the upper altitudes is easily available. The challenges are also great. The sun does not shine at all times and some kind of interface between the sun and the engine is usually necessary, most commonly as a battery. Also, the current efficiency of power conversion to power incident is low, somewhere around 20% with a theoretical maximum believed to be around the mid-30% level.
