Time to do some maths!
Crude + conservative estimate of total panel area is ~50m2 if 2 x panel segments per HLS Starship.
Assuming 1,300W/m2 solar irradiance and a pitiful 15% conversion efficiency with 50% cosine losses, we get 6kW max power or 1,450W per crew member. https://twitter.com/C_S_Skeptic/status/1384738683069157377

The Apollo LEM had a total battery capacity of 296Ah at 28V (~8kWh). Over it's 75hr design life, this averages out to ~53W per crew member.
Ofc, the entirety of the power budget was not used for life support, but I hope this quick calculation shows that the large panels are perfectly adequate for supporting a crew of 4 on the Moon.
Additionally, since Artemis missions will land near the Lunar South Pole, solar power is plentiful and the 8-10day surface mission duration will allow for near-ideal conditions.
