Looking at Solar Power? There Are a Few Things to Consider

If you’re keen to reduce your energy use with solar power there are a few things worth considering.

Your Daily Power Usage Patterns

Solar power panels need the sun’s light so they only generate electricity during the day, so it’s most economical to install a system that can supply your expected daytime electricity usage.

Of course any electricity you don’t use isn’t wasted – you’ll be able to sell it back to the grid at a feed in tariff agreed with your electricity provider.

These tariffs vary by energy retailer and from state to state, your Solahart Expert can give you an idea of what applies in your area.

Your Roof Space and Orientation

Our smallest solar power system needs just 10 sqm of roof space to generate around 30% of the average Australian household’s energy use. The more power you would like to generate the bigger the roof space you will need.

In Australia, solar power systems are most efficient when installed on a North facing roof.  The further from North your roof faces, the more the efficiency of the system is reduced.

It is best if the angle of the roof is close to the angle of latitude of your town, as that is where the sunlight falls most directly on the panels.  For example, in Brisbane (latitude: 27°) the ideal roof angle is approximately 25-30°.

Shading from objects such as buildings, trees, antennas or power lines will reduce the effectiveness of your solar panels.
