Solar in Baldivis — What You Need to Know
Baldivis is one of Perth's fastest-growing southern suburbs, with almost entirely post-2000 housing on large estates. The modern Colorbond roofs and clean electrical systems make it one of the easiest suburbs in Perth for solar installation. The City of Rockingham supports solar with no restrictions. Baldivis has a slightly inland position that means less sea breeze cooling than coastal suburbs, pushing summer temperatures higher and electricity costs up. The flat terrain, zero mature trees, and wide open sky conditions provide maximum solar generation potential. Many Baldivis homes already have solar, creating a strong network of experienced local installers.
For detailed guidance on choosing the right inverter for Baldivis conditions, see our best solar inverters 2026 guide. If you are considering battery storage, our solar battery costs and payback guide covers options for WA households.

Solar rebates in Baldivis (6171)
Baldivis sits in STC Zone 3, which sets the federal Small-scale Technology Certificate discount: roughly $1,817 off a 6.6kW system in 2026, taken off the quote by your installer rather than claimed afterwards. Bigger systems earn more certificates — a 10kW array attracts about $2,753.
On top of that, Western Australia offers the WA Residential Battery Scheme (Synergy up to $1,300, Horizon up to $3,800, VPP required) plus an interest-free loan up to $10,000. WA has no state panel rebate, but the Residential Battery Scheme stacks a state discount on the federal one for VPP-connected batteries, and the DEBS feed-in scheme pays more for 3–9pm exports — a reason to consider a west-facing array or a battery.
- Federal STC discount: ~$1,817 on 6.6kW, applied at point of sale
- Federal Cheaper Home Batteries discount: $252 per usable kWh — about $2,516 off a 10kWh battery
- State support: the WA Residential Battery Scheme (Synergy up to $1,300, Horizon up to $3,800, VPP required) plus an interest-free loan up to $10,000

What size solar system for a Baldivis home?
With 5.4 peak sun hours a day and Rockingham electricity at around 33c/kWh, each kilowatt of panels in Baldivis generates roughly 1537 kWh a year. A 6.6kW system suits most three-to-four person households; go to 10kW if you have an EV, a pool pump or a battery on the horizon, and the roof to fit 25 panels.
| System | Cost after STCs | Yearly saving | Simple payback |
|---|---|---|---|
| 5kW | $4,720–$6,930 | $1,030–$1,430 | 5.7 yrs |
| 6.6kW | $5,780–$8,400 | $1,360–$1,880 | 5.2 yrs |
| 10kW | $8,400–$12,180 | $2,050–$2,850 | 5.0 yrs |
The payback range runs from the suburb's best-case saving to a conservative estimate that assumes you use about a third of what you generate during the day and export the rest at the 2.8c feed-in rate. Self-consume more — run the dishwasher, pool pump and hot water in daylight — and the numbers improve.
Is solar worth it in Baldivis?
Yes — Baldivis earns a solid grade (None/100) on our scorecard, which makes a reasonable case. A typical 6.6kW install costs $5,780–$8,400 after rebates and saves about $1,360 a year, so it pays for itself in around 5.2 years depending on how much you use during the day, and then delivers 15–20 more years of near-free daytime power.
Coastal note: within a kilometre of salt water, ask for marine-grade (C5 or "coastal") rated mounting and panels with a salt-mist certification. It adds little to the price and protects the 25-year warranty.
Finding a solar installer in Baldivis
Look for Clean Energy Council accreditation (the installer, not just the sales company), a local track record in Rockingham, and a quote that itemises panels, inverter, mounting and the STC discount separately. Ask what happens to your warranty if the retailer closes — panel and inverter manufacturer warranties are the ones that last.
When you request quotes through SolarScorecard, we text you first to confirm the details, then share your enquiry with up to two vetted installers who service 6171. No call centres, no selling your details. Get your Baldivis solar score and ask for quotes only if the numbers look right.
