Install solar panels at an angle equel to the latitude at the site and facing the sun. (This works in both the Northern and Southern hemisphere.) Examples: Montreal, Canada: Latitude 44 degrees 30 minutes (60 minutes in one degree, so you do the math... ;-) Cabo San Lucas, Baja California Sur, Mexico: Latitude 22 degrees 53.5 minutes.
