It pretty much wouldn't do anything because of insufficient production and losses. They say it's 1.1kW, then there are geographic multipliers (sun angle), seasonal variations and less than ideal panel placement all of which will reduce the production from 1.1kW down to 700-800W or less. Then more than a 3rd of that will be wasted on keeping the computer running during charging, and if HVAC kicks in to condition the battery then even more will be wasted. And of course there is a bit of loss in the DC-AC-DC conversion. It would be a lot more interesting if the panels were over 2kW, without a battery, and direct DC output of 350-400V...
