When a solar array in Low Earth Orbit has a high voltage of 100V or higher, an arc occurs. It causes surface degradation, electromagnetic interference and other undesired side-effects. Considering a large space platform of 1MW power in future, solar array which can operate at a voltage of 300V or higher is required.

If it had, I suspect that the use of these dangerous vehicles would be restricted to “autonauts” and we common citizens would revel that highly trained “autonauts” could operate these incredible high performance automobile machines. ... The fact is, there is plenty of business for a reliable low cost system.
