Mars is about 1.5 AUs from the Sun, so light intensity (and solar power) is about (1/1.5)^2 = 44% that of Earth. That doesn't rule out solar power, but it does

Mars is about 1.5 AUs from the Sun, so light intensity (and solar power) is about (1/1.5)^2 = 44% that of Earth. That doesn't rule out solar power, but it does make alternatives relatively more appealing.
One partial source might be the burning of biomass (e.g. potato leaves and, um, other things).
