Solar panels in Glenmore Park

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 2745 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. In the estate itself most homes quote close to those numbers. Out at Mulgoa, Wallacia, Luddenham and Greendale the variable is distance: a long run from a shed or a second building back to the switchboard adds cable and labour, and we measure it before we quote rather than after.

Glenmore Park 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. The discount shrinks each January until the scheme ends in 2030, and the exact amount depends on the certificate market on your installation date.

Not on its own — and this is the single most misunderstood thing about rooftop solar. A grid-connected system shuts down the moment the grid goes out, by design and by law: it has to, so it cannot push power into lines that a crew may be working on. Sun on the roof makes no difference. What changes that is a battery with a backup circuit, which disconnects your house from the grid and keeps running from stored energy. It is an extra piece of switchgear and it has to be designed in, so it is worth deciding before the install rather than after the next storm.

You choose, within the battery's output. A typical backup setup covers lights, power points, the fridge, the internet and a few essentials — enough to make an outage an inconvenience instead of an emergency. Whole-house backup including ducted air-conditioning, an oven or a pool pump needs considerably more inverter output and storage, and is a much larger system. We size it from what you actually want to keep on, and the quote lists those circuits by name so there is no argument later.

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. Semi-rural properties are sometimes on a different arrangement to the estate streets, so we confirm your site's limit rather than assuming the standard one.

Usually not. In NSW most rooftop solar on a house is exempt development, so it does not need a development application from Penrith City Council. Rural and environmentally sensitive land is where exceptions turn up, and a ground-mounted array on acreage is treated differently from panels on a roof. If your property is out towards Mulgoa or Wallacia and you are thinking about a ground mount, ask us early and we will check it before you plan around it.

Yes. We cover the whole 2745 postcode, including Regentville, Mulgoa, Wallacia, Luddenham, Greendale. The pricing, the process and the connection paperwork are the same right across it — the only thing that changes on the larger blocks is the cable run.
