output from PV panels will vary depending on the orientation, location,
daily weather and season. On average, in summer, a panel will produce
about five times its rated power output in watt hours per day, and in
winter about two times that amount. For example, in summer a 50 watt
panel will produce an average of 250 watt-hours of energy, and in winter
about 100 watt-hours. These figures are indicative only, and
professional assistance should be sought for more precise calculations.

Trackers are used to keep PV panels directly facing the sun, thereby
increasing the output from the panels. Trackers can nearly double the
output of an array (see figure 7). Careful analysis is required to
determine whether the increased cost and mechanical complexity of using
a tracker is cost effective in particular circumstances. A variety of
trackers, which will take about 10 panels, are manufactured in
Australia."
