Solar panels in Horsley

As an estimate, a 6.6kW system comes to about $3,990, a 10kW to about $5,490 and a 13.2kW to about $7,990, with the STC discount for postcode 2530 already taken off. Those are typical figures for a straightforward install, not a fixed price. The addition that turns up here rather than elsewhere is mounting: an exposed roof needs closer rail spacing and more fixings than a sheltered one, which is more hardware and more labour. It is not a large number, but it should be in the quote rather than absorbed by cutting corners.

Horsley is in STC Zone 3, rating 1.382, the same as Sydney. 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.

It is a design input rather than a problem, and the distinction matters. Panels are not blown off well-installed roofs; poorly fixed arrays on exposed sites are where failures come from. An array is a large flat surface, and the forces on it rise sharply with wind speed and with how exposed and how high the roof is — which is why the installation standards require the mounting to be designed for the site's wind classification rather than to a single national recipe. On a ridge here that usually means rails closer together, more roof attachments and shorter panel overhangs than an identical system would need on a sheltered block in the valley.

Ask two questions. First, what wind region and terrain category the mounting has been designed for — anyone doing this properly will answer without hesitating, because it comes out of the racking manufacturer's own software. Second, how many roof attachments the layout uses, and whether that number changed for your site. A quote that is identical to one written for a flat suburban block twenty kilometres inland has not accounted for anything. We put the figures in the quote so you can compare them.

Rarely, and the honest answer is that the failure we see is almost never the panel itself. Modern panels are tested to withstand substantial wind and hail loading. What fails on a bad install is the connection to the roof — a fixing pulled through a batten, or a rail span longer than the manufacturer allows. That is an installation decision, not a product one, which is why we would rather spend your money on the mounting than on a marginally higher panel wattage.

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. The same rules apply right across the 2530 postcode.

Yes. We cover the whole 2530 postcode, including Avondale, Wongawilli, Huntley, as well as Dapto and the suburbs towards the lake. The pricing, the process and the connection paperwork are the same right across it.
