Question 1

Should I get a solar battery or just add more panels for my Canberra home?

Accepted Answer

For years our honest answer was that more panels almost always paid back faster than a battery, and for a lot of homes that's still true. But the maths shifted in 2026. A federal rebate now takes roughly 30% off battery cost, and with solar feed-in tariffs falling, storing your own power is worth more than exporting it for a few cents. So batteries have moved from rarely worth it to genuinely worth it for the right home. The right home is one with real evening usage, a low feed-in rate, and plans to stay long term. Without a battery, most homes only self-use about 30% of what they generate, where a battery lifts that to 70 to 90%. If your roof still has room and you use most of your power in daylight, more panels can still be the smarter spend. We run your actual numbers and tell you which way it falls, rather than pushing batteries because they're the upsell of the moment. A typical solar-and-battery install lands most of our clients around $15,000.

Question 2

How much does a good solar system cost in Canberra?

Accepted Answer

Solar pricing depends on system size, panel and inverter quality, and how clean the install needs to be. A common starting point for a medium Canberra home is a 6.6kW system. Larger homes, or homes adding an EV and battery, size up from there. Federal STCs come off the upfront price at point of sale, and the ACT Sustainable Household Scheme offers interest-free loans for solar that spread the cost over a multi-year term. A design-integrated system, with flush black-on-black panels, hidden conduit and the array placed to suit the roofline rather than just maximise count, sits above a builder's-special install, because the care and the components are different. The number that actually matters isn't the sticker price, it's the payback, and that depends on how much of your own power you use. We size to your real usage and give you the honest payback rather than the biggest system that fits the roof.

Question 3

What solar rebates and incentives can I get in the ACT?

Accepted Answer

Two main schemes apply to most Canberra homes, plus a battery rebate as of 2026. Federal Small-scale Technology Certificates (STCs) come off the upfront cost of an eligible system at point of sale. Your installer claims them, so the discount is on the invoice, and the value scales with system size. The ACT Sustainable Household Scheme (SHS) offers zero-interest loans for solar and batteries, which improves your effective payback by spreading the cost interest-free. On top of that, the 2026 federal Cheaper Home Batteries rebate takes roughly 30% off battery cost. There's no separate standalone ACT solar cash rebate beyond these. All of them carry caps and conditions, and the rules change, so we confirm exactly what currently applies to your situation at quote time rather than quoting a figure that's six months stale. You also have to use an accredited installer to qualify — accreditation is administered by Solar Accreditation Australia, which we hold.

Question 4

How big a solar system do I actually need?

Accepted Answer

System size should come from how much power you use and when, not from how many panels fit on the roof. The starting point is your electricity bill: your annual kilowatt-hour usage, and where possible the time-of-use data showing when you draw the most. A home with electric hot water, a pool, or an EV needs a very different system to a basic household. Here's the key trade-off. Every unit you use directly from your panels saves you the full grid import rate, but every unit you export only earns the lower feed-in rate. So we size for self-consumption first, not for the biggest export figure. A 6.6kW system is a common starting point for a medium Canberra home, but we work it out per home from your actual usage. Oversizing to chase exports rarely pays. Sizing to your daytime load, and shifting things like the dishwasher and EV charging into daylight hours, is what makes the system earn its keep.

Question 5

Do solar panels work well in Canberra's cold winters and frost?

Accepted Answer

Yes, better than most people expect. Panels generate from light, not heat, and they actually run closest to their rated efficiency on cold clear days, because high temperatures reduce output. Canberra winters are cold but often bright and sunny, which means solid winter generation. The real seasonal difference is day length. Shorter winter days mean fewer peak sun hours, so monthly output drops compared to summer. That's normal, and we factor it into every sizing calculation so a July bill isn't a surprise. Frost on the glass is temporary. It clears as soon as the sun hits it and the panel resumes generating. Snow is rare here and generally slides off a tilted roof before it matters. The point is that Canberra is a strong solar location year-round. The winters don't undermine the case, they just shift the monthly numbers, which a properly sized system already accounts for.

Question 6

Can I charge my electric car from my solar panels?

Accepted Answer

Yes, and it's one of the strongest reasons to go solar right now. An EV is a big, predictable daily load you can schedule to charge in the middle of the day when your panels are generating. A smart, load-managed charger can be set to draw only when there's surplus solar, so you're effectively filling the car from the roof instead of buying power from the grid, and displacing petrol on top of that. To do it well, the system needs to be sized to cover your base household load plus the EV charging during daylight, which we calculate from your real driving and usage. It doesn't require a battery. Plenty of clients add solar specifically because they've bought, or are about to buy, an EV, and the solar payback is often faster when it's offsetting fuel as well as power bills. We can install and integrate the charger as part of the same job so the whole thing is coordinated.
