While plugged in, especially in the A.M. before you leave, turn on the Climate Control for ~5 minutes before you leave via the Tesla app (tap the fan icon on the main app screen.) This will cool (or heat) the passenger cabin to your preferred temperature, replenish any power taken from the lithium battery from the grid. Try and use covered parking during the day to keep the passenger cabin from heating up in the sun. Cabin Overheat Protection (COP), if you set this Safety setting to be On, will use the AC while parked to maintain the cabin at or under 105F. Be aware that this can use 6 or 7 kWh over 8 hours (~750Wh/hour). The COP with No AC (HVAC Fan Only) setting uses about 1/3 of the power that the COP with AC uses but can't maintain the passenger cabin to a maximum of 105F (but still cooler than if COP is turned off.)
Tinting the glass windshield, other side glass with a good ceramic tint can help. A sunshade for the glass roof can also improve comfort while driving (sun feels less intense with a mesh sunshade installed.) Tinting the glass roof can provide some benefit but the glass roof comes with factory UV and IR (heat) rejection treatment so the improvement is less than for the windshield, other side glass and rear glass.
