It's conceivable that if solar panels were very expensive and launch costs dropped sharply, they could be placed above the atmosphere to maximize energy.

(A) Panels are in fact, inexpensive, and even with significant reductions in launch costs, the overall feasibility remains doubtful. The difficulty becomes more apparent when one considers the conditions required to keep such systems operating over time.

(B) Outside the atmosphere, by contrast, large arrays would be exposed to radiation, space debris, and constant heat, making regular intervention unavoidable and long-term operation increasingly inefficient.

(C) On Earth, however, those conditions are relatively easy to meet. Solar panels can be cleaned and managed with minimal effort and simple tools, often requiring little more than routine care.
