We have commercial satellites that also use much cheaper arrays with much higher efficiency.
Using 30 year old solar tech with a very mass-inefficient design is putting your thumb on the scale of such a comparison.
I like kilopower and am a fan (it really helps for super deep space missions that currently have to rely on the tiny amount of Plutonium-238 we have and can make), but we're going to use a LOT of solar power on Mars just as we do today.
You should use Ultraflex or similar as a standard. Instead of the ~7W/kg you used for ISS arrays at Earth orbit, you'll get ~150W/kg at Earth orbit:
