Sunny Brisbane is the ideal place to install a solar power system
. Not only do Brisbane solar panels generate more power than their southern counterparts in Sydney
and Melbourne, but the increase in sunshine hours also entitles you to receive a greater solar rebate
A typical 5kW system in Brisbane generates, on average, 21kWh of electricity every day. The average household uses 18kWh of electricity every day, so theoretically, a 5kW system can power the average Brisbane household. However, it is essential to perform your calculations
, especially as your electricity consumption habits play a significant part in how much you can save. Solar panel output will also vary a little depending on your rooftop.
The table below shows the solar panel output
of varying system sizes in Brisbane:
Panel orientation for Brisbane conditions
For generating solar power in Brisbane, it is best to position your panels so that they face north. If for example, you are only able to position your panels on a west facing rooftop, this is ok; keep in mind that they will still generate as much solar power as panels in Melbourne
that face north.
Optimum panel angle for Brisbane conditions
It is best to position your panels at the same angle as the latitude of the location
to maximise year-round solar production; for Brisbane, this means that a solar panel angle of 27.5° is optimal
. If your roof pitch is not exactly 27.5° do not despair, the panel angle is not typically a decisive factor. For example, a higher pitch will receive more sun in winter when the sun travels at a lower arc, and this may be advantageous depending on your consumption habits.
