The Solar + Battery Advantage

Why Solar Alone Is No Longer Enough

Gone are the days when people installed just solar panels. More and more Australians are now pairing their solar system with a battery and for good reason:

Double the Rebates, Double the Savings
By installing both solar and a battery, you can access multiple rebates, stacking the federal solar rebate with the battery rebate to slash your upfront costs.
Feed-in Tariffs Are Dropping
The money you get for sending excess solar back to the grid keeps going down. In some areas, you're even charged to export power. A battery lets you store and use that energy instead.
Unstable Grid? No Worries.
With blackouts becoming more common, having a battery means you can keep the lights on when the grid goes down. Stay powered up and in control, no matter what.

Customer Stories

"Having solar is the most sensible thing you can do to save money."

Robert, 1KOMMA5° Customer

Here's everything you need to know about installing a 30kW solar system:

Is a 30kW solar system the right size for my home?

A 30kW system is ideal for large homes with high energy use, or properties with EVs, pools, or home businesses. It's also suitable for small commercial spaces. If your bills are over $1,000/month, this could be a perfect fit.

How much can I save with a 30kW solar system?

You can save up to $9,000–$12,000 per year depending on your usage and feed-in tariff. Savings increase if you add a battery. Over time, the system pays for itself and then some.

How much roof space do I need for a 30kW system?

You’ll need around 135–160 square metres of roof space. With most panels now rated at 445–460 watts, you’ll need roughly 65–70 panels. We'll confirm the layout during your site assessment.

Can I add batteries to my 30kW solar system later?

Yes, you can add a battery anytime. Many customers start with solar and add storage later as energy needs grow or budgets allow. We’ll ensure your system is battery-ready from day one.

Are there rebates or incentives for installing a 30kW solar system?

Yes, government rebates and small-scale technology certificates (STCs) can reduce your upfront cost by thousands, depending on where you live. Typically, rebates for a 30kW system are around $9,900.

How much does it cost to install a 30kW solar system?

The price typically starts from $36,000. Depending on the quality and brand of panels and the inverter, the cost could go up. Premium systems with longer warranties may cost more upfront but offer better long-term value. Be sure to compare quotes and ask about hidden fees or exclusions.

What warranties are available with a 30kW solar system?

At 1KOMMA5°, we only offer premium solar panels and inverters from trusted, high-performance brands known for their reliability.
