Starship Mars Surface Power
I was doing some calculations around solar panels on Mars surface and thought I should keep it for future reference Electrolysis: 50 kwh produces 1 kg Hydrogen and 8kg Oxygen 2000kwh produces 40kg Hydrogen and 320kg Oxygen 1000t of Oxygen takes 3125 hours to produce 130 Days * 6 hours Peak Sunlight = 781 Days (approx two Earth Years) Produces 125t of Hydrogen Liquify CO2 from atmosphere Sabatier Power Requirement Assumptions 570w per metre squared insolar at Mars surface 39% Solar Cell efficiency (space panel) 230w per meter squared of Solar Cells Normal Commercial Solar Panel Dimensions (1.9mx1.3m) (2.47m2) (40mm Depth) 25kg Square that fits in a 9m diameter Starship Cargo bay has an area of 63m2 Power Specifications 1,000,000w (1Gw) divided by 230w/pm2 needs 4400m2 of Solar Cells or 1781 normal commercial sized panels 25kg each or 44t for all the panels If you create the panels in such a way as to maximise space in the quare you can fit about 25 panels worth flat in that squ...
