Solar panels in Glenwood

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 2768 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. Homes here are newer with modern switchboards, so the usual complications do not apply — the question that decides the price is how much of the size you want will physically fit.

Glenwood is in STC Zone 3, rating 1.382. In 2026 a 6.6kW system creates 45 certificates, worth roughly $1,710 off the price, and a 10kW system 69 certificates, roughly $2,622. Certificates follow the capacity you install, so a system trimmed to fit the roof earns proportionally fewer.

Fewer than the roof looks like it should take, and that surprises people. A 6.6kW system is 14 × 475w panels and a 10kW is 21 × 475w panels, each panel a little under two metres by a little over one. What eats the space on the houses here is roof shape: hips and valleys break a roof into several smallish triangles rather than one large rectangle, and panels only go in whole rows. Add the vents, the whirlybirds, the aerial and the clearance the array must keep from every edge and ridge, and a roof that looks generous from the street can take less than you would expect.

Usually because one measured and the other estimated. A quote produced without a proper look at the roof — or from satellite imagery alone — tends to assume a clean rectangle and a full row count. When the crew arrives and the panels do not fit, you get a phone call about a reduced system or a higher price, and neither is a good conversation to have on install day. Ask to see the layout drawn on your roof, face by face, before you sign. If a quote cannot produce one, it has not really been designed.

There are three honest options and we will tell you which applies. Higher-output panels put more watts in the same footprint, which costs more per panel but can recover a size that otherwise would not fit. Splitting the array across two faces uses roof that a single-face layout wastes, at the cost of some extra rail and cabling. Or you accept a smaller system, which is sometimes simply the right answer. What we will not do is quote a size that needs the panels to overhang the edge.

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. Most homes in these estates are three-phase, so the allowance rarely constrains what the roof does first.

Yes. We cover the whole 2768 postcode — Glenwood, Stanhope Gardens and Parklea. The pricing, the process and the connection paperwork are the same right across it.
