DELTA-SIERRA MARS TOOL
Mars solar + battery calculator
Educational sizing with an explicit Mars sol duration of 24.65979 h.
Essential answer
A “per sol” calculation must use the actual Mars-sol duration or state a different time basis. Here the average load is integrated over 24.65979 hours, then losses and storage are treated separately.
Every value is editable. Scenario values are not an official NASA architecture.
Calculator
Method and limitations
The previous Lot 15 multiplied by 24 h and then labeled the result kWh/sol. This is fixed: sol duration is now a visible editable input, prefilled at 24.65979 h from Mars24. Other values remain educational scenarios.
Primary sources and evidence status
The calculation distinguishes physical relation, demonstrated value, standard, educational assumption, and Delta-Sierra scenario.
