Lunar Base Power & Night Survival Simulator

Build an energy budget instead of assuming that solar panels alone solve lunar power. Set generation, load, daylight, darkness, battery capacity, storage efficiency and reserve to see whether stored energy bridges the selected night.

How the energy balance works

Daytime generation first supplies the selected daytime load. Any remaining energy can charge storage up to the entered battery capacity. The simulator then protects the selected reserve and applies the entered round-trip storage efficiency once when calculating the energy that can actually support the night load.

The difficult part is stored energy

At many lunar locations, darkness can last roughly two Earth weeks. A continuously occupied solar-powered system must generate daytime energy for immediate loads and also store enough usable energy for the long night. Battery mass and thermal management can therefore dominate the design.

Polar locations are different

Some high polar terrain receives extended illumination, while nearby depressions can remain in permanent shadow. Local topography matters; the lunar pole is not one uniform lighting environment.

Limitations

This is an energy-balance simulator, not habitat engineering software. It does not model changing solar incidence, battery degradation, temperature-dependent capacity, charge and discharge efficiencies separately, converter losses, dust, redundant buses, eclipse geometry or equipment startup loads.
