Solar and battery package deals are everywhere in Australia — installers love bundling them, and homeowners love the idea of a one-stop energy solution. But are these packages genuinely good value, or are they a way for installers to mask margins? In this guide, we break down what to look for, what to avoid, and whether bundling actually saves you money.
Common Package Configurations and Prices
Here are the most popular solar-plus-battery packages being offered to Australian homeowners in 2026, with typical price ranges for quality products from reputable installers:
| Package | Price Range (installed, after STCs) | Best For |
|---|---|---|
| 6.6kW solar + 5kWh battery | $10,000–$14,000 | Small households, basic backup |
| 6.6kW solar + 10kWh battery | $14,000–$18,000 | Average households (2–3 people) |
| 10kW solar + 10kWh battery | $16,000–$22,000 | Medium-large households (3–5 people) |
| 10kW solar + 13.5kWh battery | $19,000–$25,000 | Large households, EV owners |
| 13kW solar + 13.5kWh battery | $22,000–$30,000 | High-usage homes, full energy independence |
Red Flags in Cheap Deals
If a deal seems too good to be true, it probably is. Watch out for these warning signs:
Suspiciously Low Prices
A 6.6kW solar + 10kWh battery package for under $10,000 should raise immediate questions. Either the components are bargain-basement quality, the installer is cutting corners, or there are hidden costs not included in the headline price.
Unknown Brands
Stick with established panel brands (LONGi, Trina, Jinko, Canadian Solar, REC, SunPower) and reputable inverter/battery brands (Fronius, SolarEdge, Enphase, Goodwe, Sungrow, Tesla, BYD). Unknown brands may lack local warranty support — and if the brand exits Australia, your warranty becomes worthless.
No Itemised Quote
Any installer who won't provide a detailed breakdown of components, labour, and additional costs is hiding something. You have every right to know exactly what panels, inverter, and battery you're getting.
High-Pressure Sales Tactics
- "This price is only available today"
- "We only have 3 spots left this month"
- "The government rebate is ending soon" (it's phasing down gradually, not ending abruptly)
- Door-to-door sales reps who push for an immediate sign-up
Excessive Deposit
A deposit of 10–20% is normal. Anything over 50% upfront is a red flag. Reputable installers don't need large deposits because they have established supply chains and cash flow.
Questions to Ask Your Installer
Before signing anything, ask these essential questions:
- What specific panels, inverter, and battery are included? Get model numbers, not just brand names.
- Is the inverter a hybrid? If not, you'll need a separate battery inverter, which adds cost and complexity.
- Is backup power included? Not all battery installations include blackout protection — this often costs extra.
- Will my switchboard need upgrading? If so, is that cost included in the quote?
- What's the total installed price including GST? No hidden extras.
- What's the warranty process? Who do you contact — the installer, the manufacturer, or both?
- How long has your company been operating? Longevity matters for warranty support.
- Are you CEC-accredited? All solar installers in Australia should have Clean Energy Council accreditation.
- Can I see recent reviews or references? Check Google Reviews, ProductReview.com.au, and SolarQuotes.
- What monitoring system is included? You need to be able to track your system's performance.
Does Bundling Actually Save Money?
In most cases, yes — but the saving is moderate, not dramatic. Here's why bundling makes sense:
- Single installation visit: One crew, one day. Separate installations mean two site visits, two sets of electrical work, and potentially two sets of scaffolding.
- Shared switchboard work: The electrician is already at the switchboard for solar — adding battery circuits at the same time is more efficient.
- Hybrid inverter efficiency: A package with a hybrid inverter handles both solar and battery with one device, rather than needing separate solar and battery inverters.
- Single point of contact: One installer responsible for the entire system simplifies warranty and support.
However, bundling doesn't always make sense:
- If you already have solar: Adding a battery to an existing system is common and doesn't require a full package. An AC-coupled battery can be added to any solar system.
- If battery prices are still too high for your budget: Install solar now and add a battery later when prices drop further. The solar savings start immediately.
- If you're being pushed into a bigger package than you need: A 6.6kW solar system without a battery is a better investment than a 5kW solar system with a battery if your budget is limited.
Get the Numbers Right
Before committing to any package deal, model the financial return of each component separately. Use our Solar ROI Calculator to check the solar return and our Battery Payback Calculator to verify the battery economics. This ensures the package genuinely represents good value rather than just a convenient bundle.
