Estimates only, including GST, checked September 2026. STC figures use postcode 2147, 2026 deeming and an assumed $38 per certificate — the discount you receive depends on the certificate market on your installation date. Savings are modelled on typical usage and tariffs and are not a guarantee.
Selling and buying
What happens to solar when a Seven Hills house is sold
A solar system is fixed to the roof, so it goes with the property rather than with you. That sounds simple, and it mostly is — but three things decide whether a buyer treats it as an asset or as somebody else's problem.
The paperwork
Installation and compliance documentation, the accredited installer, and the panel and inverter models with their warranty terms. No paperwork usually means no warranty anyone can rely on.
The inverter's age
The part most likely to need replacing, and it rarely lasts as long as the panels. A buyer who knows its age can price it; one who doesn't assumes the worst.
Proof it works
A week of monitoring data, and feed-in credits on a recent bill. Between them they show the system is connected, approved and actually generating.
Warranties follow the system, not the owner
Product and performance warranties attach to the equipment on the roof, and workmanship warranties to the installation, so a change of owner does not reset them — the new owner inherits whatever remains. What does not carry across is the retail account: the buyer arranges their own, with their own feed-in rate, which is worth knowing before anyone assumes the seller's tariff comes with the house.
Network rules change and every connection is approved on its own merits — we confirm the limit that applies to your address in writing before install day.
Batteries
Adding a battery in Seven Hills
Home batteries attract two separate incentives. The federal Cheaper Home Batteries Program takes an estimated $3,402 off a 13.5 kWh battery, and NSW’s PDRS battery incentive + VPP bonus can add more on top. Already have solar? We check your inverter first — some systems take a battery as they are, others need a hybrid inverter.

Planning an EV?
Size your solar for it now. Our 10kW package comes pre-wired for a battery and an EV charger, so adding one later is a small job rather than a rebuild.
