The difference between fixed and tracked solar systems

This is a graph from an installation in Nevada USA which shows the difference in output patterns between a fixed solar array and a tracker.

At midday the output is similar between either system. The tracker does manage to get more power from the sun at other times of the day.

This has two benefits…
1. It generates more power – so this is either saving $ or producing $.
2. In a Stand Alone Power System (with batteries) it extends the life of the batteries because they are being drawn down less.
