DELTA-SIERRA TOOL — MARS

Mars solar + battery sizing calculator

Explore how load, losses, equivalent sun hours and autonomy change system size.

Essential answer

All climate and technology values are inputs. The tool deliberately avoids pretending there is one universal Martian solar yield; the reader must state the assumption.

Every value below can be changed. Prefilled values are educational examples, not an official NASA architecture.

Calculator

E_day = P_load × 24 ; E_generation = E_day/η ; Area = (E_generation/solar hours)/power density
Edit the values and run the calculation.

Method and limits

The calculator deliberately shows intermediate operations. Keep units visible, state the calculation boundary and distinguish a chosen assumption from measured performance.

A numerical result does not prove an architecture is feasible: availability, maintenance, contaminants, storage, redundancy and failure cases still require separate sizing.
