Estimates only, including GST, checked October 2026. STC figures use postcode 2526, 2026 deeming and an assumed $38 per certificate — the discount you receive depends on the certificate market on your installation date. Savings are modelled on typical usage and tariffs and are not a guarantee.
Steep and high roofs
What a hillside home in Unanderra adds to the job
The system on a steep two-storey roof in Farmborough Heights is the same as one on a single-storey house in Unanderra. Getting the crew onto it safely is not, and that is where quotes for the same size system part company.
Access
Two storeys, a steep pitch or a sloping block means scaffold, edge protection or another fall-prevention system for the whole job.
Pitch
Panels mount flush on steep roofs as they do on low ones. A steeper north face can even do slightly better in winter, when the sun is low.
The foothills
Mount Kembla sits to the west. On the highest streets it can take winter afternoon sun, so the array leans east and north there.
A quote with no access line is a question
If you live in a two-storey home or on a steep roof and the quote says nothing about scaffold or edge protection, ask how the crew will work safely. Either it has been included without being named, or it has been left out. Our quotes list it separately so you can compare like with like.
Network rules change and every connection is approved on its own merits — we confirm the limit that applies to your address in writing before install day.
Running a business in Unanderra or Kembla Grange?
Workshops, warehouses and offices use most of their power in daylight, which is when solar makes it. A business system is sized from the site’s daytime load and its connection rather than from a household bill, and the assessment looks at the switchboard, the roof structure and how much of the output the site can use itself.
How we assess a commercial siteBatteries
Adding a battery in Unanderra
Home batteries attract two separate incentives. The federal Cheaper Home Batteries Program takes an estimated $3,402 off a 13.5 kWh battery, and NSW’s NSW VPP connection incentive (battery via federal program) can add more on top. Already have solar? We check your inverter first — some systems take a battery as they are, others need a hybrid inverter.
≈ $3,402
Estimated federal rebate on 13.5 kWh of usable storage
+ NSW
NSW virtual power plant (VPP) incentive when you connect an eligible battery to a VPP, on top of the federal Cheaper Home Batteries discount. The NSW upfront battery discount ended for installs from 1 July 2025.
Planning an EV?
Size your solar for it now. Our 10kW package comes pre-wired for a battery and an EV charger, so adding one later is a small job rather than a rebuild.
From quote to switch-on
How an Unanderra install works
- Step 1
Free assessment
We look at the roof pitch, the height and the way onto it, as well as shading, the switchboard and a recent bill. On a two-storey home or a steep block, how the crew safely reaches the roof is decided here.
- Step 2
Written quote
A quote with the panel layout, the inverter and every extra itemised. Scaffold or edge protection, where needed, is its own line with the reason.
- Step 3
Network approval
We lodge your grid-connection application and confirm any export limit before install day.
- Step 4
Installation
Fall protection goes up first. CEC-accredited electricians then install, test and commission the system, and clean up.
- Step 5
Switch-on
Your retailer updates the meter and we set up monitoring so you can see every kWh.

What our customers say
“I'd like to thank Nessar and my neighbour Hasan for doing a wonderful job organising the installation of solar panels on my house. Wei and his team worked incredibly hard, especially since my home is double-storey, making the installation quite challenging. They spent the entire day ensuring everything was completed correctly. I'm very happy with the service.”
“Loved the service and the quality of the products provided. The analysis and recommendations before installation were extremely helpful. Highly recommended.”
