Solar panels in Erskine 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 2759 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. The usual variations on a home here are a concrete tile roof, which takes longer to work on than metal, and an older single-phase switchboard that needs upgrading before a larger system goes on it. Both are itemised in your written quote after we have seen the roof.

Erskine 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. From 1 October 2026, systems between 100kW and 1MW can also create STCs, with a fixed five-year deeming period, or use large-scale certificates instead. The two work differently, so we explain that at the site visit rather than on a web page.

Yes, and it is a good fit. A warehouse or distribution shed in the Erskine Park estates usually has the three things commercial solar wants: a large unshaded roof, a daytime load from lighting, dock equipment and refrigeration, and a tariff where demand charges make midday generation worth more than the feed-in rate suggests. Our standard systems run to 100kW. The roof structure and the existing main switchboard decide most of the cost, and a commercial connection is assessed individually by the network, so the approval takes longer than a home — we start that early.

Yes — most homes in this part of Penrith have one, and it is routine work. It differs from metal in two ways worth knowing before you compare quotes. It takes longer, because each mounting foot means lifting tiles and fitting a proper flashing rather than screwing into a rib; and older tiles can be brittle, so some breakage is normal on any tile job. We carry replacements and swap any we break. If a roof is near the end of its life, we will say so rather than mount 25 years of panels on it.

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. Many homes in this postcode are single-phase, so that 10kW is the whole allowance rather than 10kW three times over. Commercial sites are assessed separately and on their own terms.

For a house, usually not: in NSW most rooftop solar on a home is exempt development and needs no development application from Penrith City Council. Commercial and industrial buildings are a different matter — a large system can need approval depending on the site and its zoning, and we handle that assessment as part of the quote rather than leaving it with you.

Yes. St Clair shares the 2759 postcode with Erskine Park, and we cover both — the pricing, the process and the connection paperwork are identical. St Clair has its own page, which goes into roof age and warranties, because the housing there is a decade older than the estates on this side.
