What we install

One crew, start to finish

Every system is sized to your roof, your shading and the way your household actually uses power — not to a package on a price list.

Most popular Solar panels installed on a residential roof

Rooftop solar systems

Tier-1 panels and inverters chosen for coastal conditions and South West heat, laid out to get the most out of your roof rather than the most panels onto it. Monitoring app included so you can see what you’re generating.

Battery storage

Keep the solar you make during the day and use it at night, with backup that keeps the essentials running through an outage.

Electric vehicle charging at a home charger

EV charging

A properly wired home charger that talks to your solar, so the car fills up on sunshine instead of grid power.

How it works

Four steps, about three weeks

You’ll deal with the same two people from the first phone call to the day it switches on.

  1. 1

    Site visit

    We look at your roof, switchboard and last four bills, then tell you honestly whether solar stacks up for your place.

  2. 2

    Design & quote

    A layout drawn for your roof with panel positions, expected output and a fixed price. One page, no fine print.

  3. 3

    Approvals

    We lodge the Western Power application and the rebate paperwork, and keep you posted while it’s processed.

  4. 4

    Install & switch on

    Most homes take a day. We test, commission, set up your monitoring app and walk you through it before we leave.

What customers say

Trusted across the South West

Read all reviews

Professional and knowledgeable, and easy to deal with from the first visit. They explained what we needed and, just as usefully, what we didn’t.

JTJames T.Margaret River · 13.2 kW + battery

Start to finish the process was easy. The team were local, friendly and tidy, and they came back a month later to check everything was performing.

SLSarah L.Dunsborough · 10.5 kW solar

Quality install and a fair price. Our bills have dropped well past what we expected, and the EV charger was sorted on the same day.

MRMichael R.Busselton · 6.6 kW + EV charger

Straight answers

Questions we get asked every week

Still not sure? Call 0499 711 203 and ask us directly — no sales script.

What does a system actually cost?

For most South West homes a 6.6 kW system lands between $4,500 and $6,500 after the federal rebate, and 10–13 kW systems between $7,500 and $12,000. Adding a battery typically starts around $8,000 installed. We give you a fixed price after the site visit, not a range.

Is a battery worth it yet?

It depends on when you use power. If most of your household load happens after dark, a battery usually pays for itself well inside its warranty. If you’re home during the day, a bigger solar array often makes more sense first. We’ll tell you which one your bills point to.

How long does the install take?

A day for most homes. Battery installs and switchboard upgrades can stretch to two. You’ll know which before we start, and we clean up after ourselves.

Do you handle the Western Power paperwork?

Yes. We lodge the connection application and the rebate claim, and we follow them up. You don’t need to chase anyone.

What happens if something goes wrong later?

You call us, not a national hotline. Workmanship is covered for 10 years, panels and inverters carry their manufacturer warranties, and we handle the claim on your behalf if one is ever needed.

Can you add to a system someone else installed?

Usually. We’ll test the existing inverter and wiring first and tell you whether adding panels or a battery is sound, or whether you’d be better replacing the inverter.
