Wait — the 350 kWh/day is generated *per sol*, so over 9 sols: 3150 kWh total. Demand: 8×3.2×9 = 230.4 kWh. So they need 230.4 kWh in storage to cover during storm. But if no initial storage, they must import 230.4 kWh. But imported implies external supply — which they don’t have.

Understanding Energy Demand and Storage Needs: Why 3,150 kWh Over 9 Sols Shapes Survival in Storm Scenarios When preparing for extreme weather events—especially prolonged storms with limited sunlight—accurate energy forecasting is critical. A common calculation points to a substantial energy demand and the necessity of reliable storage. But what does that really mean? Let’s break down the energy dynamics and the real challenges in off-grid resilience. ### The Solar Generation Equation
Assume your off-grid system generates 350 kWh per sol—that’s 350 kilowatt-hours of electricity powdered daily under ideal sunlight. Over 9 consecutive sols, total solar generation adds up to: 350 kWh/day × 9 sols = 3,150 kWh
