Frequently Asked Questions

  • How do I know what size solar system I need for my Cairns property?

    Solar power is a renewable energy source that can help reduce your carbon footprint and save you money on your energy bill. The power is a clean, green energy source that doesn’t produce any harmful emissions, making it a great choice for those who want to do their part to protect the environment. In addition to being good for the planet, solar power can also save you money on your energy bill. Solar panels typically have a lifespan of 20-25 years, so they’re a long-term investment that can pay off for years to come.

  • Are solar systems effective in Cairns’ tropical climate?

    If you're planning on doing any major renovations to your home or business, it's always a good idea to check with your local electrician to see if your electrical system needs to be updated. Depending on the scope of your renovation project, you may need to upgrade your electrical panel, add new outlets, or rewire some of your existing wiring.

  • How much can I save on my power bills with solar in Cairns?

    Savings vary from property to property, but many Cairns homeowners and businesses see a noticeable reduction in their electricity bills once their system is sized correctly and used wisely. The main savings come from using the power your system generates during the day instead of drawing from the grid. Choosing efficient appliances, running high-use items (like washing machines and dishwashers) while the sun is shining, and considering options like a battery or hot water timer can all help maximise the value of your solar systems, Cairns-wide.



  • What maintenance do solar systems in Cairns need?

    Solar systems are relatively low-maintenance, but they’re not completely set-and-forget. In Cairns, it’s a good idea to have your system checked every couple of years to ensure panels, wiring, isolators, and mounting are all in good condition and compliant with current standards. Cleaning the panels to remove dust, leaf litter, bird droppings, and salt film can also improve performance. Professional inspections can pick up small issues early, helping to maintain output and protect your investment over the long term. 



  • How long does a solar installation take, and will it disrupt my home or business?

    Most standard residential solar installations in Cairns can be completed within one to two days once the design, approvals, and metering arrangements are in place. Commercial jobs may take longer, depending on the system's size and complexity. Our team plans the work to minimise disruption, keeps the site tidy, and lets you know in advance when power will need to be briefly turned off so you can plan around it. Once the system is installed, we’ll show you how it works, explain how to monitor your usage, and answer any questions you have before we leave.
