Your power bill jumps every time the AC turns on
Townsville summers don't let up, and neither does your air-con. It runs most of the day just to keep the house liveable, and by the time your quarterly bill lands, the number can be hard to look at. Add a pool pump or bore running in the background and it climbs even higher. You start doing the math before you switch anything on, wondering if a cooler house is worth what it's costing you. It shouldn't feel like a trade-off between comfort and your budget every single day.

Had a very positive experience with Solar Dimension. They were quick, thorough and also helpful in explaining to me everything I needed to know.
Just had my solar panels and battery system installed, estimated time frame 3 days but completed in under 2 days. All work was done to the highest of standards and the fitting out is fantastically neat and looks great. All the Solar Dimension staff were very professional and helpful.
After deciding to finally get solar, I received quotes from several companies. Solar Dimension stood out because they focused on what I actually needed rather than trying to upsell me on unnecessary extras. Vu was fantastic throughout the process — explaining everything clearly, making what could have been a confusing decision feel simple and stress-free.

Common questions
How much does solar and battery cost in Townsville?
The cost depends on the system size your home needs, which comes down to your power bill, roof space, and whether you have a pool or bore pump running as well. Government incentives can reduce the upfront cost, though the exact amount depends on your system size and installation date. The best way to get an accurate figure is to check your recommended system above and follow up for exact pricing based on your property.
Do I need a battery, or is solar enough on its own?
You can install solar panels without a battery. A battery lets you store extra power generated during the day so you can use it later, like in the evening when your air-con is running. Whether it's worth adding depends on your household's routine — a good installer will look at your usage pattern rather than upselling a battery you don't need.
How long does a solar and battery installation take?
Most residential installs are completed within a few days. The exact timeframe depends on your system size and how easy your property is to access. Your installer will confirm exact scheduling once they've assessed your property.
Will solar actually lower my power bill in Townsville?
Solar can reduce how much electricity you buy from the grid. Townsville's daytime air-con use overlaps well with when solar panels produce power. How much your bill drops depends on your system size, usage pattern, and whether you add a battery for evening use — there's no guaranteed saving figure that applies to every household.
Are solar and battery rebates guaranteed if I apply?
No, rebate eligibility isn't guaranteed. Incentive programs can change, get capped, or be wound back over time. Checking your eligibility earlier generally gives you a better chance of qualifying for what's currently on offer.
Does having a pool or bore pump change what system I need?
Yes. Pool and bore pumps add a steady, predictable chunk of electricity use on top of your normal household consumption. Properties with a pool, bore, or both often need a larger solar and battery setup than a similar sized home without them.
What happens after I submit my details for a quote?
A team member will follow up to confirm your details and talk through your options, then arrange a time to provide your personalised quote. You're not obligated to proceed after this conversation.
Do I need to be home during the installation?
Yes, someone will need to be on the premises to allow us to work.
Will my system still work if the power grid goes down?
This depends on how your system is set up. Some battery systems include backup capability to keep essential circuits running during an outage, while others shut off for safety reasons even with a battery installed. [Confirm which systems include grid outage backup, and any conditions]
