translates into 36,000 W/day. Figure 5.1 depicts a residential roof-mount PV array lay-
out, in Palm Springs, California and Figure 5.2 the solar power system schematic
wiring diagram.
Since the average daily insolation in southern California is about 5.5 hours, the
approximate solar power system required to satisfy the daily demand load should be
approximately 6000 W. Occupancies that are not fully inhabited throughout the day
may require a somewhat smaller system.
In general, an average 8 hours of habitation time should be used for sizing the solar
power system, which in this example would yield a total daily power demand of
24,000 Wh, which in turn translates into a 4000-W solar power system.
