SAA-accredited · Tier-1 brands only
Federally-accredited. Top-10 brands only. STC rebate applied automatically. Size your system below — takes 30 seconds — then see a firm net price you can commit to.
Step 1 — How big a system?
No sales calls. No "book a consultation." The sizing tool below uses the same rules I'd use on your roof — household size, EV plans, pool, how much you work from home — and recommends a system that actually suits how you live.

Step 2 — Pick your panels
Aiko is my first recommendation for most Sydney homes — the new ABC cell tech gets genuinely more output per square metre. Jinko if budget matters more than absolute efficiency. REC if you want Norway/Singapore-made.
Step 3 — Pick your inverter
Sigenergy's SigenStor is my default — the inverter and battery stack as one tidy unit, no separate hybrid box. GoodWe for the best value hybrid. Fronius if you want the Austrian gold standard. Sungrow for the biggest AU installed base.
Battery choice in the next step will be filtered by which battery pairs cleanly with the inverter you pick.
Step 4 — Add a battery?
Battery-to-inverter compatibility is the silent killer of dodgy solar jobs. These are the options that pair cleanly with the inverter you picked — no AC-coupling workarounds, no voided warranties.
Step 5 — Your quote
Solar FAQ
The federal Small-scale Technology Certificate (STC) rebate is a government incentive for rooftop solar. Only SAA-accredited installers (like me) can claim it on your behalf. The price you see on this site is already net of the rebate — you don't lodge anything, you don't wait for a cheque. The rebate amount depends on system size, your postcode zone (Sydney is Zone 3), and the current STC market price, which I update quarterly.
For a 6.6kW system in Sydney in 2026, the rebate is typically around $2,400–$2,600. A 13.2kW system: around $4,800–$5,100.
If my on-site assessment flags the roof isn't ready — cracked tiles, dodgy flashing, a structural issue — we pause and you fix the roof (or I refer you to a roofer I trust). No point installing panels on a roof that's going to leak in two winters. The quote stays valid while you sort it.
For most residential systems up to ~10kW, single-phase is fine. Beyond that, three-phase is often better — smoother export to the grid and you can run bigger inverters. If you've got three-phase, tick it in the sizing tool; I'll spec the system accordingly. Unsure? I'll check at the site visit, no stress.
Honest answer: it depends. For most Sydney homes with daytime occupancy and moderate evening use, a 10kWh battery pays back in 6–9 years at current grid prices. If you're rarely home during the day and feed a lot back to the grid for a low feed-in tariff, it shortens. If you're home all day and barely feed back, batteries make more sense. Build your sizing above and you'll see your specific payback.
Both excellent. The honest trade-off:
Manufacturer warranties: panels typically 25 years product + 30 years performance, inverters 10 years (extendable), batteries 10 years. My workmanship warranty: 5 years on the install itself. If something goes wrong with the install, I'm the one who comes back.
Yes. Every inverter I fit has a monitoring app (Fronius SolarWeb, SolarEdge monitoring, Sungrow iSolarCloud). You can see real-time generation, daily totals, and get alerts if something underperforms. I also check your system remotely after install to make sure it's performing to spec.
