Frequently Asked Questions

In Cairns, homeowners are entitled to rebates of between approximately $1,100 and $3,700. However, rebates depend on the size and location of your solar system. This is calculated using a sort of currency called Small-scale Technology Certificates (STCs), which are used to determine your rebate value. Smaller systems receive lower rebates, with stronger systems offering higher ones. 

If hiring our team for residential solar panel installation, we’ll provide you with an appropriate solar system and discuss your solar rebate entitlements.

Due to Cairns’ harsh climate and average household electricity use, we recommend a 6.6kW solar system, which provides around 27kWh per day. However, some properties require something a little stronger. When you engage our services, our team will perform a thorough inspection of your home and recommend a suitable system that meets your needs.

If well-designed and priced, the average payback time for a residential solar system is between 3-4 years, sometimes longer, with the appropriate maintenance and care. Additionally, solar panels have an estimated return on investment of about 450% over 25 years!

Not on their own. However, if your solar system includes a battery-ready solution, it should continue to supply power to the premises. Battery-ready solar solutions are a great way to get the most out of your solar system as they store excess power accumulated throughout the day, acting as an energy ‘backup’ when you need it most.

Absolutely! Cairns has strong sunlight for about two-thirds of the year. During the lower light seasons, though, your solar panels will continue to produce sufficient energy for your home, operating at about 25%, depending on the strength of UV rays. This ability to generate power throughout the year, regardless of the weather, presents a wonderful opportunity for Cairns homeowners to benefit from solar energy.
