Solar panels in Harrington 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 2567 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. Most homes here are newer and simple to work on — modern switchboard, metal roof, often three-phase — so the quote usually lands close to the figure. The decision that costs or saves you real money is the size, not the extras.

Harrington Park is in STC Zone 3, rating 1.382. In 2026 a 10kW system creates 69 certificates, worth roughly $2,622 off the price, and a 13.2kW system 91 certificates, roughly $3,458. The discount shrinks each January until the scheme ends in 2030, and the exact amount depends on the certificate market on your installation date.

A pool changes the answer more than most people expect. A typical single-speed pump drawing around 1kW and running six hours a day uses roughly 2,000 kWh a year on its own — comparable to the rest of an average household's daytime use. The good news is that it is the most flexible load in the house: it does not care when it runs. Set the timer to the middle of the day and that consumption comes off your own roof instead of your bill. Practically, a pool household in this estate is usually looking at 10kW rather than 6.6kW, and we size it from your actual bill rather than the pool's volume.

If yours is an older single-speed unit, it is often the cheapest efficiency gain on the property — a variable-speed pump can run longer at lower power for the same turnover and use markedly less energy doing it. We do not sell pool equipment, so treat that as advice rather than a quote: we would rather you spend less on the pump and put the savings into a system that is sized right. What we will do is set the timing so whatever pump you have runs in your solar window.

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 this estate are three-phase, which is what makes a 13.2kW system straightforward here.

Almost never, but it is worth checking rather than assuming. Master-planned estates around Harrington Park were sold with design guidelines, and some of them are registered on title and outlast the build — occasionally with something to say about what is visible from the street. That is a private agreement between you and the community association, separate from council, and separate again from the network's connection approval. In NSW, rooftop solar on a house remains exempt development regardless. We raise it at the assessment so you can check before install day rather than after.

Yes. We cover the whole 2567 postcode, including Narellan Vale, Currans Hill, Smeaton Grange, as well as Narellan and Mount Annan. The pricing, the process and the connection paperwork are the same right across it.
