Isorads (contours)
showing the annual average daily solar energy
available (in MegaJoules per square metre per
day, MJ/m2day) for a fixed solar collector facing
north and tilted to the latitude angle for near
optimum year round performance.
By way of example,
the solar energy available in western Victoria
on an average day (18.1 MJ/m2day) would provide
about 1 kWh (kiloWatt hour) of electricity through
a commercially available system comprising a small
battery bank and two square metres of solar panel
with an overall efficiency of just 10%. This is
ample to light 4 rooms for 10 hours each using
fluorescent lighting of either the compact or
conventional tube designs.
Energy from the sun can be used
to generate electricity (solar-electric), or heat
(solar-thermal). Victoria has excellent solar
resources, for example, Mildura receives 90% of
Brisbane 's solar radiation levels.
Victoria's average yearly global solar exposure
on a horizontal surface ranges between 12-20 Megajoules
per square metre per day (MJ/m2/day).
