For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy..
Think of your panel's orientation as the direction it's facing in terms of north, south, east and west. The angle is how flat (lying on its back and facing straight up) or tilted your panel is..
Therefore, the ideal solar panel angle for your array would be about 34 degrees..
A rule of thumb for optimizing the angle of your solar panels is to mount them at an angle equivalent to the site’s latitude, facing due south. The latitude of Normal, Illinois, is 40.5°. [pdf]
