## Overview
Solar in Sydney only pays if it's sized properly for your daytime consumption and installed with quality gear that lasts 15+ years. We design systems around your actual usage (bill and interval data pulled from your retailer), not a generic "6.6kW fits all" default — most Sydney households benefit from 8-10kW of panels feeding a hybrid inverter that's battery-ready even if you don't add the battery on day one.
For battery storage we install Tesla Powerwall 3, Sungrow SBH, and Alpha ESS SMILE — sized to your evening load, not oversold. A well-sized battery covers the evening peak and overnight base load, cuts grid import by 70-90%, and keeps essential circuits alive during a blackout. The NSW battery rebate (from 2024) is available to eligible households and we handle the paperwork.
Every install is designed and signed off by a CEC-accredited designer/installer — the legal requirement to unlock STC rebates. We handle Ausgrid grid-connection approval, the switchboard changes required for solar/battery integration, EV-charger-ready wiring and CT clamps for consumption monitoring, and the compliance package your retailer needs for feed-in tariff.

## FAQs
**How big a system do I need?**
Most Sydney households sit best on an 8-10kW panel array. Enough to cover daytime consumption, charge an EV or battery, and generate a healthy feed-in on sunny days. Bigger isn't always better — over-sizing beyond your export limit wastes money.

**Is a battery worth it?**
For most households on a Sydney time-of-use tariff, yes — a properly-sized battery cuts grid import by 70-90% and pays back in 6-9 years with the NSW rebate. If you already have solar and pay high evening tariffs, the payback is shorter.

**Do you handle rebates and paperwork?**
Yes — STC rebate, NSW battery rebate (where eligible), Ausgrid grid-connection approval and retailer feed-in tariff notification are all handled by us.

**How much does a solar and battery system cost?**
A quality 6.6kW system starts around $5,500 after STC rebate. 10kW solar + 10kWh battery lands around $18,000 after STC and NSW battery rebates. Written fixed quotes provided after a proper site assessment.

**Are you CEC-accredited?**
Yes — CEC-accredited design and install (legally required to claim the STC rebate). All electrical work certified with a Certificate of Compliance.

**Can the battery keep the house running in a blackout?**
Yes — Tesla Powerwall 3 and Sungrow SBH both support whole-home or essential-circuit backup. We wire it as part of the install so lights, fridge and Wi-Fi stay live through outages.

**Will you match a cheap door-knocker quote?**
No — we'll show you exactly what you'd be getting for that price (usually tier-3 panels, an unsupported inverter and no consumption monitoring) and quote a properly-designed system that will still be running in year 15. Cheapest and best rarely overlap in solar.
