Local knowledge

Solar on bigger, leafier blocks

Onkaparinga Hills has larger blocks, lots of established trees and the Onkaparinga River National Park on its doorstep. Trees are great until they shade your roof, so we map shade at the site visit and place panels where they'll actually produce.

Where part of a roof gets shade, Tigo optimisers help stop one shaded panel dragging the rest of the string down. On some blocks a shed roof is a better spot for the panels than the house.

Being on the semi-rural edge, outages can hit harder here, especially in summer. A battery with backup can keep essentials running when the grid drops out. For a remote shed or a block without a cheap grid connection, off-grid solar is worth a look.

What we do in Onkaparinga Hills
Nearby work: Nearby in Kangarilla we've done off-grid builds and a 27.5 kW solar and 96 kWh Sigenergy battery system at the Kangarilla General Store.

FAQ

Questions people ask us.

Do trees around my Onkaparinga Hills property rule out solar?

Not usually. We check where the shade falls through the day and the seasons, then place panels and pick the inverter setup to suit. If solar won't pay its way on your roof, we'll tell you.

Do sloping or multi-level roofs cost more?

They can take a bit longer to install safely, which can affect the price. It's assessed on site and shown on your itemised quote, not added as a flat surcharge.

Can a battery keep my power on in a blackout?

Many can, if the battery and inverter support backup and your switchboard is set up for it. We'll explain which circuits will stay on before you buy.

Can you power a shed that's a long way from the house?

Yes. Depending on distance and what you're running, that might be a sub-main from the house or a standalone off-grid system. We'll quote the options side by side.

How far is Onkaparinga Hills from you?

A few minutes. Our workshop is in Hackham, right next door.

What did your recent Onkaparinga Hills install include?

In September 2026 we installed 8.7 kW of solar with a 24 kWh usable GoodWe battery on three phase, and put the hot water on a solar timer so it heats from the panels. It came to about $15,400 after rebates, incl GST. Every quote is free and itemised.
