| 8kW ~18 panels | $8,609–$11,649 | −$1,889 | $6,720–$9,760 | $1,300–$1,800 | 4.6–6.3 yrs |

Most Devonport homes land on 6.6kW ($5,780–$8,400) or 10kW ($8,400–$12,180). Go bigger if you run ducted air-con, a pool pump or charge an EV — the fixed install cost is spread over more panels, so cost per kW falls as the system grows. Not sure? The free Devonport solar score sizes it from your bill.

Devonport solar panel prices by quality tier
"Solar panel price" in Devonport really means three markets. Budget systems suit a simple north-facing roof; mid-range is where most installs land; premium buys efficiency (more kW on a small roof), 25-year product warranties and panel-level monitoring. All installed, after STCs.
| Tier | 6.6kW | 10kW | 13kW | Per watt |
|---|---|---|---|---|
| Budget — Tier 2 panels, basic string inverter | $4,770–$6,932 | $6,932–$10,051 | $8,665–$12,560 | $0.89/W |
| Mid-range — Tier 1 panels, Fronius / Sungrow / GoodWe | $5,780–$8,400 | $8,400–$12,180 | $10,500–$15,220 | $1.07/W |
| Premium — REC / Maxeon panels, Enphase micro-inverters | $7,576–$11,010 | $11,010–$15,964 | $13,762–$19,949 | $1.41/W |
Anything under $0.77/W in Devonport deserves hard questions: which panel brand, who holds the warranty, and whether the installer (not just the salesperson) is CEC-accredited.
Solar rebates in Devonport (TAS) that set these prices
- Federal STC discount: $1,558 off 6.6kW and $2,361 off 10kW in Zone 4, taken off the quote by the installer. Deeming drops to 4 years on 1 January 2027, so the same system costs roughly $312 more next year.
- Tasmania: the Energy Saver Loan Scheme (interest-free up to $10,000).
- Federal Cheaper Home Batteries discount: $252 per usable kWh — about $2,516 off a 10kWh battery, $3,397 off 13.5kWh. Steps down 1 January 2027.
Tasmania has lower sun hours, but the Energy Saver Loan Scheme lets you finance solar and batteries interest-free, and Aurora's regulated 8.9c feed-in tariff is the best in the country — exported solar is worth more here than anywhere else. Full detail on the TAS solar rebates page.
STC Zone 4 ×1.185 certificates per kW
$1,558 off a 6.6kW system in Devonport — the federal discount your installer deducts at point of sale. The tropics (zone 1) earn the most certificates per kW; Melbourne, Hobart, Canberra and Tasmania (zone 4) the fewest.
- Zone 1 ×1.622
- Zone 2 ×1.536
- Zone 3 ×1.382
- Zone 4 ×1.185
Adding a battery in Devonport
A 10kWh battery installed with the solar costs $6,984–$9,984 after the federal discount; a 13.5kWh Tesla Powerwall 3 class unit $8,603–$11,603. At 30c/kWh and a 9.3c feed-in rate, every kWh you shift from export to evening use is worth about 21c, so a 10kWh battery adds roughly $605 a year on top of the panels.

What moves a Devonport solar quote up or down
- Roof: tile and steep-pitch roofs cost $300–$800 more than Colorbond; two storeys adds scaffolding or a boom lift
- Switchboard: an old board with no room for a solar breaker adds $400–$1,200
- Phases: three-phase homes need a three-phase inverter (+$400–$900) but can export more
- Shading and orientation: split east/west arrays or optimisers add $500–$1,500 but recover most of the lost output
- Timing: STC deeming steps down every January, so an identical system costs a little more next year
Solar in Devonport: the short version
Devonport gets about 3.6 peak sun hours a day, sits in STC Zone 4 (a $1,558 federal discount on 6.6kW), and pays around 30c/kWh for electricity with a 9.3c feed-in tariff. On those numbers a 6.6kW system costs $5,780–$8,400 installed and pays back in 4.8–6.6 yrs. Tasmania has lower sun hours, but the Energy Saver Loan Scheme lets you finance solar and batteries interest-free, and Aurora's regulated 8.9c feed-in tariff is the best in the country — exported solar is worth more here than anywhere else.
Regional pricing note: Devonport quotes run about 5% above the national average for travel and a smaller installer pool. Two or three like-for-like quotes close most of that gap.
Solar panel prices by Devonport suburb
Prices barely move suburb to suburb inside Devonport — roof type and switchboard matter more than the postcode — but each suburb page carries its own STC zone, feed-in rate, adoption rate and payback so you can check your street.
Finding a solar installer in Devonport
Look for Clean Energy Council accreditation (the installer on the roof, not just the sales company), a track record in Devonport and the surrounding region, and a quote that itemises panels, inverter, mounting and the STC discount. Ask who services the system in year five.

Devonport solar cost questions
How much does a 6.6kW solar system cost in Devonport in 2026?
$5,780–$8,400 installed after the federal STC discount of about $1,558, for Tier 1 panels and a quality string inverter. Premium panels with micro-inverters run to about $11,010.
How much does a 10kW system cost in Devonport?
$8,400–$12,180 after STCs. It is the better buy for homes with air-conditioning, a pool or an EV: cost per kW is lower than 6.6kW and the extra export still earns the 9.3c feed-in tariff.
What is the payback period for solar in Devonport?
About 4.8–6.6 yrs on a 6.6kW system saving $1,070–$1,490 a year. Self-consume more during the day (dishwasher, hot water, pool pump on timers) and you land at the short end.
Is solar cheaper in Devonport than the rest of Australia?
Devonport prices are about 5% above the national average ($5,500–$8,000 for 6.6kW). Freight, labour and a smaller installer pool push quotes up.
Are these prices the ones installers will actually quote?
They are the installed, GST-inclusive ranges we see across Devonport quotes in October 2026, refreshed monthly from the Solar Choice price index, Clean Energy Regulator STC values and installer quotes. A quote outside the range is not automatically wrong — ask what is driving it.
