I thought the thing to do these days is put them flat and as close together as practical. You lose a few points of efficiency but double the number of panels you can fit in a given area. And panels are so cheap that this trade-off makes perfect sense.
Can fit more if you tilt them a little bit. Also easier for maintenance/access, although they don't need much if at all beyond some cleaning.
