Solar panels in Sanctuary Point

As an estimate, a 6.6kW system starts from $7,410, a 10kW system starts from $10,300 and a 13.2kW system starts from $11,250 (with battery prices starting from $4,290), with the STC discount for postcode 2540 already taken off (incl. GST for metro areas; regional areas subject to freight and travel costs). Those are starting estimates for a straightforward install, not a fixed price. For a household that is home during the day, 6.6kW is more often the right answer here than the larger sizes — and we would rather sell you the size that suits than the one with the bigger number on it.

Sanctuary Point is in STC Zone 3, rating 1.382 — the same zone as Sydney, so nothing is lost by being down the coast. In 2026 a 6.6kW system creates 45 certificates, worth roughly $1,710 off the price. That discount comes off the price at the point of sale rather than being claimed back later, so the figures above already include it and there is no paperwork for you to chase.

Better, and by a wide margin — this is the single best case for rooftop solar there is. The value of a system comes from using what you generate rather than selling it: on the figures this site models with, a kWh you use at home is worth about 6 times a kWh you export. A household that is out from eight until six exports most of its generation at the lower rate. A household that is home can run the washing machine, the dishwasher, the heating or the air-conditioning in the middle of the day and use it directly. Same roof, same system, considerably better result.

Not necessarily, and it is worth being clear about why. A battery earns its keep by storing generation you cannot use at the time, for use after dark. If you are home during the day you are already using a large share of it directly, which is the cheapest possible outcome — there is nothing to store. That makes the battery case weaker here than it is for a household that is out all day, not stronger. It can still be worth it for evening load or for backup, but it should be a separate decision made on its own numbers, after you have seen what the panels alone do.

It can be, and the honest framing matters more than the sales pitch. Solar replaces a bill you are already paying with a one-off cost, so the question is how long that takes to come back and whether the money is available now. We will show you the payback on your own bill, not an average one. It is also worth checking, separately from anything we do, whether you are receiving every energy rebate or concession you are entitled to — those are administered by the state and have nothing to do with buying a system, but they reduce the same bill, and plenty of eligible households have never claimed them.

Anything with a timer or a switch: the washing machine, the dishwasher, the pool pump if you have one, and hot water if it can be moved off an overnight circuit. Reverse-cycle heating and cooling is the big one in winter and summer — warming or cooling the house while the sun is up costs you nothing extra if the panels are covering it, and the house holds that temperature into the evening. None of this needs new equipment, which is why we raise it before anyone talks about batteries.

The distribution network that owns the poles and wires in your street approves it — not your retailer — and we lodge the application for you. That network also decides how much your system may export: on a flexible export connection, eligible customers can send up to 10kW per phase back to the grid most of the time, while a fixed export limit caps exports at 1.5kW. For a household using most of its own generation, that limit rarely binds.
