How much does a solar system cost? There are so many factors that come into play before the final figure that it is extremely difficult to estimate.

Below we have gone into detail on the different factors that will likely impact your bottom line cost of solar installation.

The Top Factors Influencing The Cost Of A Solar System Installation in Queensland

Obviously, cost varies from property to property, depending on a variety of different factors. We’ve detailed some of the most important considerations below to give you the best idea of what to think about when planning their solar installation. Remember that if you need further information or a quote that’s customised to your individual requirements, the team is happy to help.

Your Roof and Panel Aspect

Although traditionally people have accepted that a north-facing aspect is going to generate the most power (on the basis that the sun is at its highest point in the north), this isn’t always the case. Although a PV cell will be exposed to more light in the north, it will also get much warmer than if it faced slightly east or west.

A hot PV cell is less efficient than one that’s kept at a lower temperature, as there is a drop in voltage between the cells as the temperature rises.

Generally, PV cells that face the north-east, through the north, to the north-west are likely to generate the most energy.

If your panels are going to have a good aspect, it’s likely you can buy a less efficient model and still generate sufficient energy to recoup purchase costs.

The Type Of PV Cell

There are several different types of PV cells, each of which has a different price point.

These are:

Monocrystalline PV cells – These have an efficiency of around 18% and are the cheapest type of cell.

Polycrystalline PV cells have an efficiency of 14-16%. They are slightly cheaper than a monocrystalline option.

Thin-film solar panels – These have around 9-13% efficiency. Their flexible, lightweight structure enables them to be installed in locations that wouldn’t be suitable for a larger, more rigid cell.

PV Cell Size

As you would expect, larger cells are almost always more expensive than a smaller option.

Amount Of Direct Sunlight

We get a considerable amount of sunlight here in Queensland. With more than 300 days of sunshine each year, Queensland is a great place to install solar panels.

Installation Considerations

Depending on the pitch of the roof and the type of panels you choose, there may be additional installation considerations. For example, there might be a need to ensure fixings that are resistant to deterioration by saltwater if you live in a coastal location.

Some installations will also require barriers to prevent birds from nesting underneath the panels.

Solar Rebates And Grants

The Queensland government offers rebates and interest free loans for homeowners opting for a solar power installation. If you are eligible for these initiatives, they can make a solar installation far more affordable.
