Choosing the right residential solar system begins with understanding your household’s energy usage, roof layout, and long-term goals. The most suitable system will match your daytime consumption, future needs, and the physical characteristics of your property, while also incorporating high-quality components for long-term reliability. Batteries are worth considering if you use significant power at night, want backup during outages, aim for greater energy independence, or plan to support future loads such as EV charging or air conditioning. For many households, installing a battery-ready system provides strong savings now with the flexibility to add storage later as needs and incentives evolve.

Frequently Asked Questions
Are there rebates available?
In North Queensland, 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.
When pursuing our TREU Solar team for residential solar panel installation, we’ll provide you with an appropriate solar system and discuss your solar rebate entitlements.
How long do solar panels last?
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.
Will my solar panels work in a blackout?
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.
Are solar panels still effective in wet weather?
Yes – solar panels are still effective during rainy or cloudy parts of the year. While they do produce less energy compared to clear, sunny days, they continue generating electricity because panels work from light, not heat. Diffused sunlight that passes through clouds is still captured by the solar cells, typically resulting in around 10–40% of normal output depending on cloud density and conditions.
