How does PV angle affect output?

The latitude of where your solar system is installed will affect your solar output.

Here is how PV Collector Tilt away from your latitude will affect PV panel output (shown as a percent of the potential for 100% output, and 41 degrees latitude is assumed)

Top row is tilt from the horizon (south), side column is degrees (east or west) from true south.
