Challenge missions
Mission 1: Shade shock
Lower system efficiency to 65%. How much energy and savings disappear?
Mission 2: Bigger roof
Double the panels. Does solar cover the whole station, or is some energy unused?
Mission 3: Investor pitch
Find settings that make payback under 8 years. Which number helped most?
Mission 4: Public message
Practise explaining the project clearly in one extra language.
