My bay window faces SW and I have bright sun from around 1pm until the sun sets which in summertime is around 9 to 9:30 pm, I have to keep the draperies closed as it get really hot in the living room, temperature can get up to 125 behind those drapes so I have to remove the plants on the really hot days as soon as the sun hits the window or they get fried, then I put them back when the sun sets. Winter time it is the opposite, gets too cold at night so I have to remove them at sunset, I get a lot of exercise moving those plants back and forth.
