Regarding solar power it's currently hard to fulfill all of the requirements
Which is why I mentioned beamed power. Perhaps thin-film solar panels could be used for range/endurance extension. Since these craft are more weight challenged than space challenged, perhaps hydrogen fuel cells could be used instead of batteries?
