Solar panels in Hoxton 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 2171 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. Housing here spans about three decades, so the variable is the switchboard: the 1990s homes often need an upgrade, the newer ones off Cowpasture Road rarely do.

Hoxton 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 certificates go to whoever owns the system, which on a rental means the landlord rather than the tenant.

It depends on something most quotes skip: you pay for it, and your tenant gets the lower bill. That is the split-incentive problem, and pretending it does not exist helps nobody. Where it does stack up is when the system supports the rent or the asset — a property that is easier to let, lets faster, or lists with a genuinely lower running cost — and when you are holding the property long enough for that to matter. The STC discount goes to you as the owner. We will give you the generation and savings figures for the house so you can judge it against your own numbers rather than ours.

Not on your own initiative, because it is a permanent alteration to someone else's property — you need the owner's written consent, and in practice the owner arranges and pays for it. What you can do is make the case, and it is a reasonable one: a system improves the property and costs the owner nothing to run. If it helps, we will provide a written quote and a savings estimate addressed to the owner or the managing agent, and we are happy to talk to them directly. Anything portable — a plug-in battery, a balcony panel — is a different product and not something we install.

The system belongs to the property, so warranty work is arranged with the owner, but we are not precious about it: if a tenant calls because an inverter is showing a fault, we will take the call and sort out the paperwork afterwards. What we ask is that the owner tells us who the contact is at install time, so nobody is chasing a managing agent to get a light switched back on.

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. On a tenanted property the application goes in the owner's name, though the retail account stays with the occupant.

Yes. We cover the whole 2171 postcode, including Cecil Hills, as well as Carnes Hill and the estates around it. The pricing, the process and the connection paperwork are the same right across it.
