What's in a 10kW Sydney install
The $10,900 isn't just panels on a roof. Here's what's actually in the system, and why each piece matters.
24 × Jinko Tiger Neo 415W panels
Jinko is a Tier-1 manufacturer on the Clean Energy Council's approved list. The Tiger Neo series uses N-type TOPCon cells, which means lower degradation than the older P-type panels (about 1% loss in year one, then ~0.4%/year for 25 years). Product warranty 12 years, performance warranty 30 years. They make about 14,200 kWh/year on a north-facing Sydney roof.
Fronius Primo 10.0-1 inverter
Single-phase string inverter, made in Austria. The reason it's the default for Sydney homes: it has a full Australian service network, ten-year warranty, integrated Wi-Fi monitoring via the Fronius Solar.web app, and known compatibility with both Ausgrid and Endeavour grid-connection requirements. If something goes wrong, a sparky can get it fixed inside 48 hours.
Mounting + DC + AC + grid connection
Rail-style mounting for tile or Colorbond roofs (specified per your house), DC string wiring through proper conduit, rooftop isolator, switchboard isolator, separate solar circuit on its own breaker, and the grid-connection paperwork with your DNSP (Ausgrid or Endeavour depending on suburb). Plus the CES (Certificate of Electrical Safety) lodged within 7 days.
What 10kW actually does to your bill
Sydney sits in STC Zone 3, which translates to about 1,420 kWh per kW per year on a clean, north-facing roof. So a 10kW system makes ~14,200 kWh/year.
The real question isn't how much it generates — it's how much you self-consume. Power you use directly off the panels saves you the full retail rate (around 32c/kWh in Sydney in 2026). Power you export goes back to the grid at a feed-in tariff of around 5c/kWh.
Typical Sydney household economics
- Generation: 14,200 kWh/year
- Self-consumed (30%): 4,260 kWh × 32c = $1,363/year saved
- Exported (70%): 9,940 kWh × 5c = $497/year earned
- Total annual benefit: ~$1,860
- Simple payback: $10,900 ÷ $1,860 = 5.9 years
- Panel warranty: 25 years performance
Households that shift bigger loads to daytime (pool pump, dishwasher, EV charging, heat pump hot water) lift the self-consumption rate to 50%+, which cuts payback to under 4 years. A battery does the same thing for evening loads but doubles the system cost.
Should you add a battery?
A 13.5kWh Tesla Powerwall 3 adds $11,900 to the install. So 10kW + Powerwall = $22,800 all-in. The shorter answer:
- Add a battery if: you use a lot of power after sunset, you're on a high-tariff retailer (>35c/kWh), you have an EV you'd like to night-charge from stored solar, or you have frequent grid outages.
- Skip the battery if: your evening use is low, your tariff is sub-30c, or you're more focused on shortest payback than energy independence. The panels-only payback is faster.
The Sungrow SBR096 10kWh battery is a cheaper alternative at +$7,500 — same modular battery used by Tesla's commercial competitors, full Australian warranty network. Worth considering if you want some battery but the Powerwall premium isn't justified.
How the STC rebate works
The Small-scale Technology Certificate (STC) is a federal scheme that subsidises solar installs. It works like this:
- Your installer registers the system with the Clean Energy Regulator after install.
- The regulator issues a number of STCs based on system size, location (zone), and the deeming period remaining until 2030.
- The installer sells those STCs on the open market (currently ~$38.50 each) and passes the value through as a discount on your invoice.
- A 10kW Sydney system in 2026 is worth about 97 STCs, so the rebate is roughly $3,700.
Only SAA-accredited installers can claim it. If a quote says "system price excl. STC" and asks you to claim it yourself, walk away — you can't, only an accredited installer can. The displayed Power Play prices are already net of STC.
Why some quotes are $6,000 for "10kW"
Five things hide behind a cheap solar quote:
- Tier-2 / Tier-3 panels from brands that disappear in five years (when you actually need warranty support).
- No-name string inverter with no Australian service centre. When it fails in year four, you're shipping it overseas.
- Avanco-recalled DC isolators still being installed despite the recall. Look up the brand on the recall list before signing.
- Subcontracted install through a phone-room sales operation. The sales person is in Melbourne, the installer is whoever was free that week.
- "Approximate STC value" in the quote, with the actual claim done at a lower rate after install. You wear the difference.
