This is mostly true on Mars too except perhaps the eternal light part

  Mars has a lot more benefit here, in that it has a normal-length day. Much better to reliably have sunlight for roughly half of every day than to rely on a few polar areas that are in sunlight most of the time. The equator of the Moon is more suitable for other reasons, so what are you going to do, put the solar panels at the poles and run long power lines down to the equatorial regions where the power is used? Nah. Mars is better for solar power because you won't need nearly as much battery capacity, as you get light on a ~24 hour cycle same as Earth. The Moon with its slow rotation is much more challenging.

    On the minus side, Mars gets less than half the amount of sunlight per square meter.
    • CydeWeys 7y ago
      That's true, but I think the fact that you get light reliably every day is still a big point in its favor. It's probably a lot less mass total to send up twice the solar panels and 18 hours' worth of batteries vs half the solar panels but 16 days' worth of batteries. Solar panels are pretty light; batteries are not.

    Plus Mars has an atmosphere (95% CO2, 3% Nitrogen, 2% Argon, 1% other at 1% of Earth atmospheric presure IIRC), which the Moon utterly lacks. Compress that into a tank and you can chemically (or biologically) convert that into an oxygen-nitrogen atmosphere to breathe.
